A Systematic Design Method For Modeling Complex Processes And Interactions In Web Hypermedia Applications

Sehingga kini, aplikasi hipermedia web telah berkembang daripada sebuah laman web ringkas dan statik kepada sebuah aplikasi laman web yang lebih kompleks, bagi menyokong turutan proses-proses yang kompleks dan interaksi dalam navigasi. Kemunculan pelbagai ciri dalam reka bentuk web dan konsep permodelan seperti permodelan domain konseptual dan struktur navigasi telah membawa kepada isu-isu baru dalam paradigma pendekatan permodelan. Untuk memberi gambaran yang lebih jelas sesuatu paparan struktur reka bentuk domain aplikasi hipermedia web, pereka bentuk web haruslah mengenalpasti dan menentukan dengan jelas secara keseluruhan aspek reka bentuk yang wujud dalam aplikasi yang berkaitan. To date, web hypermedia applications have evolved from a simple static information webpage to a more complex web application, supporting sequence of complex processes and navigation interactions. The coexistence of various web design features and modeling concepts in conceptual application domain and navigation structures, have raises new issues on the modeling approach paradigm. To provide a clear structured view on the design of web hypermedia application domain, web designers should identify and clearly define the whole design aspects exist in such applications

A modeling approach for the development of process driven web applications

Complex web applications have been developed rapidly as to support complex process and transactional workflows involved in the web domain. Although there are numerous modeling concepts exist in web applications nowadays, new issues raises in modeling approach such as user interactions, interrelated process flow, navigational issues and graphical user interface concerns. In this paper, we present and discuss user interaction diagram, Unified Modeling Language (UML) notation and object-oriented approach for necessity in complex web applications. A proposed model called UEWDM (UML-Extensions Web Design Model) emphasize on the user interaction issues as well as the interrelated process, navigation and graphical user interface. The uniqueness of UEWDM is in the design pattern modeling approaches. At the end of the paper, future works of the design model will be explained and briefly summarized

Conceptual Modeling in Web-based Hypermedia Engineering with Com HDM

The coexistence of different complex features in web hypermedia applications such as information structures, navigation access mechanisms. and user interface interaction, raises new issues on the user-centered modeling approach paradigm. Thus, to provide a clear structured view of application domain, web designers must identify and clearly define complex processes existed in such applications

An integrated conceptual model of visually impaired users' experience and technology acceptance of a website

Internet has become one of the most important needs in our daily activity. It has benefited all its users inclusive the disabled community. There are wide spectrums of Internet’s disabled users. However, the aim of this paper is to present an integrated conceptual model focusing on understanding visually impaired users’ experience and technology acceptance of a website. This model will be used in further empirical study on modelling the relationship of visually impaired users’ experience and technology acceptance on web application. The evaluation of the model will be conducted using a pilot study. Series of questionnaire and structural equation modelling is expected to be used as tools for future. data collection and analysis

User experience design (UXD) of mobile application: an implementation of a case study

The success of an application is tied directly to the degree of the user acceptance. Analyzing user expectation and acceptance prior to the development process is vital to make a successful product. User experience design (UXD) is the research field which identified users’ needs, expectation and acceptance when there is an interaction with a product or service. Due to the lack of UXD guidelines, we will be presenting the UXD strategy for mobile flight booking ticket application (MFBTA). MFBTA is a complex application that has various type of transaction inclusive the dynamic interaction and ecommerce component that requires perceivable UXD elements. Based on the observation, it shows that UXD in MFBTA is yet to be improved in order to achieve a high degree of user acceptance and expectation

Effective keyword query structuring using NER for XML retrieval

Purpose: A more effective way for searching XML database is to use structured queries. However, using query languages to express queries prove to be difficult for most users since this requires learning a query language and knowledge of the underlying data schema. On the other hand, the success of web search engines has made many users to be familiar with keyword search and therefore they prefer to use a keyword search query interface to search XML data. The purpose of this paper is to propose and evaluate XKQSS, a query structuring method that relegates the task of generating structured queries from a user to a search engine while retaining the simple keyword search query interface. Design/methodology/approach: Existing query structuring approaches require users to provide structural hints in their input keyword queries even though their interface is keyword base. Other problems with existing systems include their inability to put keyword query ambiguities into consideration during query structuring and how to select the best generated structure query that best represents a given keyword query. To address these problems, this study allows users to submit a schema independent keyword query, use named Entity Recognition (NER) to categorize query keywords in order to resolve query ambiguities and compute semantic information for a node from its data content. Algorithms were proposed that find user search intentions and convert the intentions into a set of ranked structured queries. Findings: Experiments with Sigmod and IMDB datasets were conducted to evaluate the effectiveness of the method. The experimental result shows that the XKQSS is about 20% more effective than XReal in terms of return nodes identification, a state-of-art systems for XML retrieval. Originality/value: Existing systems do not take keyword query ambiguities into account. XKSS consists of two guidelines based on NER that help to resolve these ambiguities before converting the submitted query. It also include a ranking function computes a score for each generated query by using both semantic information and data statistic as opposed to data statistic only approach used by the existing approaches

Semantic shot classification in soccer videos via playfield ratio and object size considerations.

This paper presents a semantic shot classification algorithm for soccer videos. Generally, each shot within a match video is assigned either a far or close up-view class label. Initially, the playfield region for each frame within a shot is identified through low-level color image processing. An additional property is then considered namely the largest object size overlapping the playfield. Class labels are then accordingly assigned to each frame based on carefully constructed rule-sets. Majority voting is finally performed where the dominant frame labels within each shot is used as the ultimate class label. Experiments conducted on six soccer matches with varying camera shooting styles have been very promising, where the additional consideration of largest object size is able to significantly reduce the number of misclassifications
