    Multimedia XML data is a collection of multiple types of data sets tagged by XML elements. Such XML data can be retrieved not only by a Boolean connection with keywords but also by tag element-based query languages. In many cases, however, keyword-based queries result in either too many hits or too few results. It is not clear either what query to formulate in order to obtain a “good” ... View full abstract»

    Call centers are at the core of today's customer relations management. Increasingly, they are also utilized internally as competence and knowledge centers. Turning them into service centers of the future (SCotF) requires parallel communication over several channels, including Internet services, in a distributed synchronous fashion. In this paper, we show that the emerging XML standards provide a g... View full abstract»

    The widespread use of the World Wide Web in recent years has opened up universal access to a vast number of information sources. An obstacle that affects the access to Web data is the lack of an information structure among and within Web pages. This raises a need for structured Web page management for efficient Web information searching. Our proposed structured Web page management is built in two ... View full abstract»

    Current distance learning is mostly based on Web technologies. However, course materials announced as Web documents do not have a normalized structure. It is difficult for students to realize where they are in a Web navigation graph. On the other hand, a text book has a fixed structure, such as the hierarchy of chapters and the index. A text book reader knows how to start searching for information... View full abstract»

    In this investigation, we discuss optimization issues of meta-queries for databases. Since traditional techniques can't be applied to meta-queries, we propose a new technique of cost-based optimization without the evaluation of meta-objects. For this purpose, we introduce signature techniques and extend database schemes View full abstract»

    Recently, the Internet has become very widely used and the number of Web pages has been increasing. The authors believe that it is possible for many Web pages to become educational materials. Therefore, they focus on a learning environment using Web pages. They propose a novel framework called WECE (Web based Educational Customize Environment). WECE adds knowledge (annotations, questions, answers,... View full abstract»

    To speed up fetching web pages, this paper gives an intelligent technology of web pre-fetching. We use a simplified WWW data model to represent the data in the cache of web browser to mine the association rules. We store these rules in a knowledge base so as to predict the user's actions. Intelligent agents are responsible for mining the users' interest and pre-fetching web pages, based on the int... View full abstract»

    Current Web search engines are based on keyword search, and relevance of a web page is dependent on the number of hit count on the keywords. As keyword matching is not at the same level as semantic matching, the searching scope is unnecessarily broad and the precision (and recall) can be rather low. These problems give rise to undesirable performance on web information searching. In this paper, we... View full abstract»

    Traditional information retrieval techniques require documents that share enough words to build semantic links between them. This kind of technique is greatly affected by two factors: synonymy (different words having the same meaning) and polysemy (a word with several meanings), also known as ambiguity. Synonymy may result in a loss of semantic difference, while polysemy may lead to wrong semantic... View full abstract»

    Web based distance learning is a trend of instruction delivery. One of the most difficult challenges of such a learning mechanism is the assessment of students' learning criteria. It is hard to judge the behavior of a student since the instructor is separated spatially and temporally from the students. However, it is possible to rely on some Web based tools to keep track of a student's course atte... View full abstract»

    Introduces a frame metadata model to facilitate the continuous association rules of Web transactions. A new set of association rules can be derived with the updating of the Web log file by the Web transactions in the frame metadata model. This model consists of two types of classes: static classes and active classes. The static classes describe the Web transactions of the association rule table. T... View full abstract»

    Most of the existing techniques for the characterization of Web documents are based on term-frequency analysis. In such models, given a set of documents, the characterization of each document is represented by a feature vector in a vector space. However, as Web documents written in HTML are semi-structured by means of tags, the traditional techniques that assign term weights only by the frequency ... View full abstract»

    Constraint Databases (CDBs) are the combination of Constraint Logic Programming (CLP, which is one of the strategic directions in computing research) and database technology. CDBs represent a new kind of post-relational databases, naturally extending relational, deductive, or object-oriented databases by making feasible the use of constraints to represent possibly infinite but representable comple...

    Several projects in various disciplines are now using the Standardized General Markup Language (SGML) tags at an interpretive level, i.e. these projects contain tags which have the potential to provide the reader with additional information that is not already explicit in the text itself. One such interpretive project is the Orlando Project, which is an integrated history of women's writing in the... View full abstract»

    Like other authors, we believe that hypermedia systems, and especially the World Wide Web, can increase and improve their functionality by means of making the semantics of the information system structure explicit. In this paper, we justify the need for a cognitive model in the conception of hypermedia systems. A semantic-dynamic model is presented that provides a complete, adaptive and evolving c...

    The mediator/wrapper approach is used to integrate data from different databases and other data sources by introducing a middleware virtual database that provides high level abstractions of the integrated data. A framework is presented for querying XML data through such an Object-Oriented (OO) mediator system using an OO query language. The mediator architecture provides the possibility to specify...
