A Case Study of Online CommunityA Case Study of Online Community

Автор: Jason Ohler

One of the earliest studies of online community, pre-Internet, that considered the ethos, activities and goals of one of the earliest computer conferencing communities in existence. In it, we see the beginnings of Facebook and other online communities that are commonplace today. This study considers what is truly important in an online community, why people turn to them, and what they ultimately get from them. Above all, it points to the future we now take for granted, in which we all live two lives, one online and one in geographic community, and considers how we blend those in one integrated approach to living. This study is well suited for anyone trying to understand the phenomenon of online community today, the roots of Facebook and other other cyber gatherings, and where our current push into cyberspace as a new territory for human colonization might take us.

A CITATION ANALYSIS OF MLIS DISSERTATIONSA CITATION ANALYSIS OF MLIS DISSERTATIONS

Автор: CHUN KEAT YEAP

Many academic libraries attempt to source their collections from all the publications available. However, librarians may fail in this attempt because of some economic factors that prevent them from building a comprehensive collection of materials. The increasing price of periodicals and books and the unchanged budget for inter-library loan have precluded librarians from providing their best reference service to users. This study makes a contribution in topping a list of core journals cited in Library and Information Science (LIS) dissertations. A core list is helpful for students to use as a guide when they carry out a literature review. The aim is to identify the characteristics of cited literature in Master of Library and Information Science (MLIS) dissertations submitted to University of Malaya. This includes finding out the various type of information resources used in research projects as well as other main variables, such as: language distribution of cited documents, publication...

A Classification Method to Extract Knowledge from Text DocumentsA Classification Method to Extract Knowledge from Text Documents

Автор: Fathi Saad,Beatriz de la Iglesia and Duncan Bell

This book addresses the problem of text classification. The main motivation is the accurate classification of medical text reports. Such documents contain important information about patients, disease progression and management, but are difficult to analyse and query with conventional techniques due to their unstructured nature. We show how these medical reports can be classified automatically with a high degree of accuracy. A novel method is developed for accurate classification of medical reports. The method uses clustering as a pre-processing step to improve the final classification accuracy. The work requires the investigation of different methods for document representation, clustering and classification. In addition, it requires the use of Natural Language Processing tools. A new approach that requires minimal labelling effort, is found to be an effective classification tool for this task. Results show that the approach produces good classification performance on a real-world...

A comparison of Android against J2ME for location-based servicesA comparison of Android against J2ME for location-based services

Автор: Takayedzwa Gavaza

Since ancient times, man has been curious to find out his location. Ancient people used landmarks, stars and verbal queries to locate themselves. In the middle ages, man used compasses and maps to find out his locations. The mobility, portability and the ever increasing services that are being offered by mobile devices has led people living in the current world into focusing on embedding Location Based Services (LBS) into mobile devices. This is a result of the curiosity for knowing each other’s present position and the mobile user’s current position. This is a feature that can be used to locate a mobile device or the user carrying the mobile device. To accurately locate a mobile device, developers must have the right tools to make it easier and more efficient to develop, deploy and manage location-based applications on mobile devices. As a result of the hunt for better tools, new mobile platforms like Android are now emerging and joining the competition with well established...

A Component Testing Approach Supported By a CASE ToolA Component Testing Approach Supported By a CASE Tool

Автор: Fernando Raposo da Camara Silva

The reuse of assets instead of building them from scratch, a process generally known as software reuse, can be considered a good option of competitive advantage for software development companies. In this context, component-based development has been one of the most used techniques applied to promote software reuse, establishing a promising component market. However, the main consolidate methods to develop components are more aware in demonstrating component development as a feasible approach and some important activities, for example, related to quality, and more specifically, to testing, are sometimes neglected. Component producers have difficulties to design their products to work properly on different contexts of use, as well as to prepare their products to be validated by third party. In the same way, component consumers have limitations to test if external components, these ones addressing specific needs of their systems under development, work as specified, and if they are able...

A Computer Experiment Oriented Approach to Algorithmic ComplexityA Computer Experiment Oriented Approach to Algorithmic Complexity

Автор: Soubhik Chakraborty and Suman Kumar Sourabh

This book forms the much needed strong interface between algorithmic complexity and computer experiments using a careful blending of traditional ideas in algorithms with untraditional research in computer experiments (esp. fitting stochastic models to non-random data). While establishing the aforesaid interface, the important role of statistical bounds and their empirical estimates obtained over a finite range (called empirical O) is discovered as a bonus. While these bounds are very valuable for the average case, our research suggests in addition that there is no need to be over-conservative in the worst case just as the statistical bounds safeguard against making tall optimistic claims for the best cases. In short the statistical bounds have a sense of "calculated guarantee" that is neither too risky nor too conservative. In parallel computing, with every change of the processor, it can be argued that it is the weight of the operation that changes. Hence, if the...

A CONCATENATIVE TURKISH TEXT-TO-SPEECH SYSTEMA CONCATENATIVE TURKISH TEXT-TO-SPEECH SYSTEM

Автор: Zeliha Gormez and Zeynep Orhan

This study is intended to build the framework of a concatenative TTS (Text to Speech) system for Turkish. The system is based on concatenative, unit selection approach. It contains two different speech databases comprised of units which are directly recorded and cut from a continuous speech. Some digital signal features such as zero crossing rate and energy of speech have been used. PSOLA (Pitch Synchronous Overlap and Add) algorithm has been used for smoothing while concatenating the units. Some subjective tests are used to measure the success. The quality of the synthesized speech is measured depending on intelligibility, the ability to be understood, and naturallness, the closeness to human speech. Mean Opinion Score (MOS) has been used for naturalness and Diagnostic Rhyme Test (DRT) and Comprehension Test (CT) have been applied for intelligibility. Although the system uses simple techniques, it provides promising results, since the method is very well suited...

A Content Delivery System for Computer Aided Language InstructionA Content Delivery System for Computer Aided Language Instruction

Автор: Shyma Mohaisen

North American children have a variety of cultural and linguistic backgrounds. For children whose mother tongue is still being spoken at home, maintaining and advancing parental linguistic instruction is an ongoing effort. This effort must be upheld by the parents and other classroom based media if the child is to preserve and further his mother language acquisition. We propose a means for computer assisted language delivery based on an expandable language content delivery system. The system is applied to the instruction of the Arabic language for grade one, second language instruction. All aspects of the delivery process are demonstrated in terms of letter shape, composition, recognition, connection shapes, and relevant vocabulary models. The model discussed in this thesis is relevant to the instruction of cursive languages such as Urdu or Persian. We drew on relevant research to enhance and contrast our system where necessary. A total of seven students were asked to use the...

A contribution to enterprise interoperability maturity assessmentA contribution to enterprise interoperability maturity assessment

Автор: Wided Guedria

Many models, methods, methodologies and tools exist to help an organization, an enterprise, or more generally a system, to develop interoperability with its partners. However, most of existing works in this domain have been done to develop operational solutions to solve interoperability problems. Basic and fundamental researches, allowing characterizing and measuring the potential of an enterprise to interoperate, are still missing. In particular, this thesis deals with the definition of metrics for evaluating enterprise interoperability. By focusing specifically on interoperability maturity, a Maturity Model for Enterprise Interoperability (MMEI) is elaborated. The proposed MMEI is based on existing relevant maturity models and extends existing works to cover all main aspects and dimensions of enterprise interoperability. Possible contribution from existing scientific theories, in particular General System Theory considered as most relevant, are investigated and core concepts are...

A Decision Model for IT Supplier SelectionA Decision Model for IT Supplier Selection

Автор: Lucas Goncalves Grossi and Jose Antonio Calvo-Manzano

In the past few years IT outsourcing has gained a lot of importance in the market and, for example, the IT services outsourcing market is still growing every year. Now more than ever, organizations are increasingly becoming acquirers of needed capabilities by obtaining products and services from suppliers and developing less and less of these capabilities in-house. IT supplier selection is a complex and opaque decision problem. Managers facing a decision about IT supplier selection have difficulty in framing what needs to be thought about further in their discourses. The main objective of this work is the development of a decision model for IT supplier selection that will try to decrease the amount of failures seen in the relationships between the client-supplier. Most of these failures are caused by a not well selection of the supplier. In the case study, nine different Spanish companies were analyzed based on the IT supplier selection decision model developed in this work. Two...

A Decision Procedure For The WSkS LogicA Decision Procedure For The WSkS Logic

Автор: Tomas Fiedor

Various types of logics are often used as a means for formal specification of systems. The weak monadic second-order logic of k successors (WSkS) is one of these logics with quite high expressivity, yet still decidable. Although the complexity of checking satisfiability of a WSkS formula is not even in the ELEMENTARY class, there are approaches to this problem based on deterministic tree automata that perform well in practice, like the MONA tool that efficiently solves the class of practical formulae, but fails for some others. This work extends the class of practically solvable formulae with the use of recently developed techniques for efficient manipulation of non-deterministic automata (such as the antichains algorithm for testing universality) and designs a new decision procedure using non-deterministic automata. The procedure is implemented and is compared with the MONA tool and for some cases yield better results than MONA.

More recently, with an increase in distributed approaches to the study of Multi-Agent Simulation (MAS), those critical issues such as interoperability among distributed simulation systems, time synchronization, and performance efficiency have become major research object. Up to present, most related research works have been focus on virtual environment simulation model, while studies that are concerned with providing an analytic simulation framework which can make future estimation for target systems are quite relatively few. Therefore, in this thesis, we proposed an extensible event-driven agent-based simulation infrastructure (E2ASI). With this infrastructure, we try to enhance interoperability, deal with time synchronization mechanism, and conduct statistical analysis in hope of mitigating those issues as mentioned above. In addition, to verify the accuracy of E2ASI, we conceived an example scenario ran with both traditional sequential simulation technique and E2ASI. By comparing...

A Desktop System for Attack-Resistance and Rapid RecoveryA Desktop System for Attack-Resistance and Rapid Recovery

Автор: Todd Deshane

General-purpose computing devices, such as PCs, and the operating systems that run on them provide more functionality and capabilities than most users will ever want or need. Too much of the burden of keeping these computer systems secure is placed on the end users. Users are often required to keep the operating system, applications, security software, and anti-virus definitions up-to-date. Even with the latest security updates, users are still susceptible to the newest exploits. When a system does become compromised, the process of then restoring it to a usable state can frequently result in the loss of personal data stored on the system. Personal data can often only be recovered through repeated effort and in some cases can never be recovered. In addition to problems caused by malicious software (malware), software bugs and conflicting software packages can also cause system instability and data corruption. This book describes a unique desktop system architecture solution to the...

This is a study to identify the contributing factors of crashes on road curves and understand the effect of various dependencies between these factors on crash severity. Data mining techniques are employed based on the ability to identify patterns and the various dependencies between the contributing factors among vague, uncertain and imprecise data that characterised the insurance incident records. Results are more meaningful when the dependencies between the contributing factors are determined. This technique complements existing statistically based tools approach to analyse road crashes. The data mining approach is supported with proven theory and will allow road safety practitioners to effectively understand the dependencies between contributing factors and the crash type with the view to design tailored countermeasures.

A Fast Recognition System For Isolated Printed CharactersA Fast Recognition System For Isolated Printed Characters

Автор: Ahmed Shaffie

The purpose of this book is to propose a new multi stage algorithm for the recognition of isolated characters. The algorithm can be applied for any isolated character such as Latin, Chinese, Japanese, and Arabic characters but it has been applied in this paper for Arabic characters, since the Arabic characters OCR systems are rarely considered in literature, so the challenge was to use the system on non-Latin script .The approach uses normalized and isolated characters of the same size and extracts an image signature based on the center of gravity of the character and then compares this values to a set of signatures for typical characters of the set. The system then provides the closeness of match to all other characters in the set which is expressed in a triangular confusion matrix. This algorithm is believed to be new and, to the contrary of earlier investigations, its accuracy and running time can be tuned to get the best strategy for any character set.

A Framework for Designing Home TelecareA Framework for Designing Home Telecare

Автор: Farah Magrabi

Communications and information technology are enablers for new models of healthcare delivery in the home. Existing methods do not systematically account for the overall process of implementing home telecare. The specific structural and process aspects of utilising home telecare in healthcare delivery have largely been overlooked. This study proposes a framework that divides the design of home telecare into six stages. The framework is shown to be a valid structure in terms of the broad objectives of each of the design stages and its applicability in implementing a model for cystic fibrosis. The framework is generic, the specific instances of which will vary according to the home telecare model in question.

A Framework for Evaluating ICT Integration in Teacher EducationA Framework for Evaluating ICT Integration in Teacher Education

Автор: John Oredo and Freddie Acosta

This book proposes a framework for evaluating ICT integration in Teacher Education. The material presented in this book is distilled from a research that was done using primary school teacher training colleges in Kenya as a case study.This research was motivated by the fact that there is a lot of disjointed initiatives aimed at integrating ICT into education in Kenya with little effort directed at evaluating the impact of these initiatives. This has created a gaping rhetoric-reality gap that new research efforts need to bridge.The research presented in this book is a step towards bridging this gap by proposing a framework to guide evaluation of ICT in Education. Though this research used primary teacher education as a case study, its findings can provide insight and a basis for further research in evaluation of ICT integration at other levels of Education. This book can be of use to researchers and practitioners in the field of Technology in Education. Teachers at primary and...

A Framework for ICT Implementation in Public Primary Schools in KenyaA Framework for ICT Implementation in Public Primary Schools in Kenya

Автор: Michael Warui

Despite the emergence of ICT resources - such as computers, multimedia and the Internet, the proportion of public primary schools in Kenya making use of ICT is still very low. This research revealed that lack of technical support and access to educational software and e-content, and limited understanding on how to integrate ICTs into teaching were perceived as the key barriers to the further uptake of ICT in primary schools. Consequently, schools are unable to embrace an effective learning and quality pedagogy as they relate to ICT integration. This dissertation developed a framework that would support, describe and promote good practice in the use of ICT in learning and teaching in public primary schools. To help schools introduce sustainable ICT into learning environments, this framework has seven basic execution steps. In each step, a school has to undertake several activities as the inputs in the execution of the framework. There is a resultant outcome after execution of each...

A Framework for Managing Patients Medical RecordsA Framework for Managing Patients' Medical Records

Автор: Ebenezer Afari-Kumah

Patient medical data are collected at the hospitals of low resource settings but they are not processed electronically. In the current medical record management system, the majority of out-patients do not have a full medical record. Thus, physician’s time is wasted by having to collect all the information again. In addition, it becomes very difficult to keep track of the patients and to review a patient’s medical record. A Data Mart was designed and built using Microsoft Access 2000 Database Management Systems (DBMS) to collect, store, organize and retrieve medical information of patients at the Medical Records Unit of a Hospital. The Data Mart was mined to provide timely, accurate and reliable reports adequate for clinical research and improving health care continuity. The Data Mart interfaces are intuitive and easy to use. The queries are flexible and the reports well labeled.

A Framework For Testing As A ServiceA Framework For Testing As A Service

Автор: Iman Sadooghi

Software testing has become almost the most important phase of software development. In recent years, several testing tools have been developed to accomplish the testing phase of the project. Most of these products cannot perform software testing in very large scales. Testing as a Service (TaaS) is the latest solution that has been proposed for this problem. It is a specific type of Software as a Service (SaaS) that performs software testing. It will be launched over the cloud environment and uses cloud’s unlimited resources to test software in any scale. The goal of the TaaS is to create an application that is very scalable and flexible in testing. This book explains the procedure of designing a framework for TaaS that supports functional, performance and scalability testing for online and offline applications.

A Framework to Measure Intranet Usage in Kenyan Public UniversitiesA Framework to Measure Intranet Usage in Kenyan Public Universities

Автор: Kelvin Omieno

These days intranets are becoming more and more popular throughout the business world and other types of organizations including learning institutions. This study develops and validates a credible body of evidence supporting the value of corporate intranets in relation to learning institutions’ productivity. There are currently no accepted frameworks or methodologies to compare and evaluate Intranet usage in Kenyan public universities. Part of the difficulty for adopting a common comparison framework for intranets in institutions of higher learning (IHL) is that they are in constant reform and, more importantly, they have strong financial, social and cultural links and implications. The aim of this book is to develop a framework of measuring corporate intranets usage in Kenyan public universities. Factors such as organizational, technological and individual factors are perceived as possible contributors to effective intranet usage and service quality in IHL. Other three variables...

A Fuzzy Logic Approach to Property Searching in a Property DatabaseA Fuzzy Logic Approach to Property Searching in a Property Database

Автор: Jiri Slaby

Properties are a very important commodity in any contemporary market. To find the right property for a targeted purpose still seems to be a hard task. With the development of computers and electronic information systems and with the evolution of the internet; electronic property portals and databases have emerged. The search function within these databases is capable of producing fast results, but only results that match ‘hard specified’ criteria. However, the need of a user is different as he seeks the ‘best’ result according to his preferences. Currently no public property portal offers the possibility to accommodate user’s preferences into the search. The approach of the user when searching for a property is shown. Theoretical analysis of this problem with mathematical possibilities of how to solve it is presented. Then a fuzzy approach to searching incorporating user preferences (with theoretical and practical background) is proposed. Finally the verification of the fuzzy logic...

A Fuzzy Set Theoretic Approach To CPU SchedulingA Fuzzy Set Theoretic Approach To CPU Scheduling

Автор: Vandana Rana and Diwakar Pandey

About the work- The contents of this work are based on the research work of the authors in the field of CPU scheduling. Quite a lot of work has already been done in this area and several scheduling algorithms are available in the literature. Most of the existing algorithms select a process from the ready queue on the basis of one of the three major attributes attached with an admitted process; that is- time of arrival, size of CPU burst and its priority. Main features of this work are that its process selection criteria is based on the effect of the combination of more than one attributes and the use of fuzzy set theoretic techniques make it tolerant to imprecise and uncertain knowledge of parameters. Fundamental concepts, techniques, some basic scheduling algorithms and a brief review of the current literature, have been introduced in the beginning of the work to facilitate smooth onward reading.

A Fuzzy-Mathematical Model to Motion Detection with Monocular VisionA Fuzzy-Mathematical Model to Motion Detection with Monocular Vision

Автор: Suneth Pathirana

Vision based inference for mobile robots in order to avoid obstacles, is one of the most attracted areas for both domains of Computer Vision and Robotics. Computer Vision, more specifically the vision for intelligent machines enables mobile robots to perceive the external world with 'wisdom'. Therefore Vision based obstacle avoidance has become one of the major research areas of Robotics. Estimating the motion path and predicting the motion behavior of a dynamic object with only single camera (monocular vision) is a real challenge. We realized this can be done by analyzing a sequence of image frames extracted from a live video stream. But, these analytic techniques must be extremely fast in real time processing, since the decision drawn within reasonably short response time is the only 'god' to safeguard the robot & ensure the safety of others in environment! Therefore, we postulate a fuzzy-mathematical model: an Artificial Intelligence approach to achieve the ultimate objective,...

A Generalized Approach To Amharic Text-to-speech(TTS) Synthesis SystemA Generalized Approach To Amharic Text-to-speech(TTS) Synthesis System

Автор: Alula Tafere,Million Meshesha and Sebsibe H/Mariam

A text-to-speech (TTS) synthesis system converts natural language text into speech. However, written text of a language contains both standard words (SWs) and non-standard words (NSWs) like numbers, abbreviations, synonyms, currency, and dates. These NSWs cannot be detected by an application of “letter-to-sound” rule.This work try to produce Amharic TTS system, which handle both standard words(SWs) and Non-standard words (NSWs) of Amharic language. The model described in this work has two major parts: Natural language processing (NLP) and Digital signal processing (DSP). The NLP handles the text analysis (transcription of the input SWs and NSWs) and extraction of the speech parameters. The DSP further enable to generate the artificial speech. Finally, the performance of the system shows that on the average 73.35% words both SWs and NSWs correctly pronounced. In addition, an assessment of intelligibility and naturalness of synthesized speech using MOS testing techniques results a...

A generalized architecture for linear transformA generalized architecture for linear transform

Автор: Swapan Kumar Samaddar,Atri Sanyal and Amitabha Sinha

This book is discussed with FPGA implementation of the combined processor of Linear Transform, which can be partially reconfigured. It contains the SIMULINK files (*.mdl) which are block design files of various transform systems such as FFT, DCT, Walsh and Hadamard. From the SIMULINK model appropriate languages (VHDL) for the target boards (FPGA) can be generated. The codes generated from SIMULINK for the target boards are usually convoluted, and may not be the most efficient. But, the time it takes to implement complex systems using SIMULINK is considerably shorter than manually coding in VHDL. The VHDL code for transform scheme is given and the code is run in MODELSIM XE III /Starter 6.1e-customXilinx Version. Here the target board is XILINX VIRTEX-IV PRO.

A generic architecture for e-Government and e-DemocracyA generic architecture for e-Government and e-Democracy

Автор: Carlos Grima-Izquierdo

Is online electronic vote (e-Voting), using Internet, secure enough? Could someone view or change my vote? If I pay my taxes online, could my financial information be compromised? How can I ensure that a hostile government does not commit fraud? Is it possible to design a generic, extensible, scalable, reusable and highly secure software architecture to develop an e-Government system? Is the direct democracy through Internet (e-Democracy) realistic? This book, the author’s PhD thesis, tries to solve all these questions. Using UML, it proposes an architecture to implement any e-Government, for any country at any level (local, national, supranational...), and with any political and administrative layout. It includes both administrative (eg: paying taxes) and decision-making procedures (eg: voting), and there are no paper-based traditional processes. This book also finds and catalogues all typical security problems in e-Government and e-Democracy, researching solutions for all of them....

A Generic Framework for Medical Image SegmentationA Generic Framework for Medical Image Segmentation

Автор: Agam Adityas Nugroho

Medical image segmentation is challenging and requires more sophisticated algorithms. Medical images are obtained by several different modalities and each of them has certain characteristics. For this reason, there is a need for developing a method which works for any kind of medical images. Deformable model is one of the most popular method in medical segmentation that requires some features (such as an edge) to be present along the boundary of the object, and pull the deformable curve toward that feature. This methods may be sensitive to the starting position and may leak through the boundary of the object if the edge feature is not salient enough in certain regions in the image. On the other hand, level set method evolves a contour implicitly by manipulating a level set function .In this book, we implemented level set region-based method to segment several images from different modalities. Its performance is tested by comparing the segmented results with those obtained by...

A Generic Natural Language Processing Tool for OdiyaA Generic Natural Language Processing Tool for Odiya

Автор: Sasmita Sahoo and Sachi Nandan Mohanty

Computational Linguistics involves both the branches, computer science and linguistics and deals with the computational aspects of natural language phenomena, where one of its goals is to give computers the ability to properly understand natural language texts. The two main directions in contemporary Computational Linguistics are Natural Language Processing (NLP) and Natural Language Generation (NLG) respectively. The purpose of NLP is to design and build a computer system that will analyze ,understand and generate languages that humans use naturally,so that eventually one can address the computer as though he is addressing another person.NLG is enabling computers to produce syntactically correct natural language texts conveying the semsntic meanings from some underlying non-linguistics representation of information. In this project, we will develope some NLP tools which expected to be building blocks of complex NLP systems. Here we have developed a grapheme to phoneme converter for...

A Genetic Algorithm Scheme to Solve Complex Triangle ProblemA Genetic Algorithm Scheme to Solve Complex Triangle Problem

Автор: Swapan Kumar Samaddar

This book provides a scheme based on genetic algorithm (GA) to solve the complex triangle elimination (CTE) problem of rectangular dualization approach in VLSI floor planning. Rectangular dualization, where each module is realized as a rectangular area, is an important approach in VLSI floor planning. It is known that if the input adjacency graph contains a complex triangle (CT), i.e. a cycle of three edges that is not a face, and then its rectangular dual does not exists. Elimination of CTs therefore becomes essential before constructing a floor plan. There are two versions of the CTE problems -weighted and unweighted adjacency graphs. The weighted CTE problem is known to be NP-complete (Sun, 1993). Recently it has been proved that unweighted problem is also NP-complete. In this paper we present a genetic algorithmic scheme to solve unweighted CTE problem and weighted CTE problem.

A GIS Data Model for Disease Surveillance and MonitoringA GIS Data Model for Disease Surveillance and Monitoring

Автор: Peter Adebayo Idowu

Despite the fact that Sub-Saharan Africa is a region characterised by high rates of several deadly diseases, there is relatively little consistent or reliable data that can be used for surveillance, monitoring and management of these diseases in the region. In order to alleviate the problem of patchy and inconsistent epidemiological data, a well structured, interoperable spatial data model for disease surveillance and monitoring is developed. This book reviews some of the existing health data models which were modified and extended to develop a data model for disease surveillance, monitoring, and management. The data model captures information required for the development of diseases surveillance systems. The model is developed using the Unified Modelling Language. The work aims to produce the model as an open standard in order to promote collaboration and encourage researchers in developing nations to contribute to the maintenance of the data model. The model is implemented in...

A Goal-oriented Approach for the Development of Web ApplicationsA Goal-oriented Approach for the Development of Web Applications

Автор: Jose Alfonso Aguilar Calderon

In recent years, new proposals have emerged to address the development of Web applications, some of which focus primarily on the representation of the Web application at a certain level of abstraction (conceptual model) while others are focus on specific tasks of the development process ignoring the requirements phase. Due to the increasing complexity of Web applications (ie., the changes in the implementation technology) the requirements phase is more difficult to maintain. As a result, a problem arises in these proposals: the absence of a design guide that facilitates the development of Web applications based on user needs and expectations. To overcome the lack of such process, this book presents an approach for the development of Web applications based on the Model-Driven Architecture. Specifically, we propose the especificacion of the requirements of the Web application in a conceptual model by using as modeling language the goal-oriented framework called i* (iStar) with which is...

A Group Agent Architecture Based on FIPA and OntologyA Group Agent Architecture Based on FIPA and Ontology

Автор: Chih-Hao Liu and Jason Jen-Yen Chen

Web service is a standard for publishing services for users to access. Currently, more and more services are provided on various web sites. Notably, users access web services based on their preferences. An autonomous mechanism for dynamic and intelligent access to such personalized web services is thus a necessity. Using agent and ontology technologies seem to provide this much-needed capability. Unfortunately, there seems to lack either enough knowledge representation to operational concepts of agent or the engines to use the knowledge. This book presents a novel group-based agent architecture, in which the operational ontologies and engines are proposed to generate semantic behavior to solve the problem above. Combining it with user ontology, preferred value of services can be evaluated dynamically by agent to access personalized web service. We further extend the 22 FIPA communicative acts to propose 13 group communicative acts and 3 associated interactive protocols in order to...
