    In this paper we present a hybrid text categorization method based on Rough Sets theory. A central problem in good text classification for information filtering and retrieval (IF/IR) is the high dimensionality of the data. It may contain many unnecessary and irrelevant features. To cope with this problem, we propose a hybrid technique using Latent Semantic Indexing (LSI) and Rough Sets theory (RS)... View full abstract»

    At present, there are no association rule mining algorithms that are suitable for use in electronic commerce because they do not consider that new products are introduced and old ones are retired frequently and they assume that support thresholds do not change. In this paper a new algorithm called Fast Online Dynamic Association Rule Mining (FOLDARM) is introduced for mining in electronic commerce... View full abstract»

    A meta-search engine acts as an agent for the participant search engines. It receives queries from users and redirects them to one or more of the participant search engines for processing. A meta-search engine incorporating many participant search engines is better than a single global search engine in terms of the number of pages indexed and the freshness of the indexes. The meta-search engine st... View full abstract»

  • Support IR query refinement by partial keyword set

    Publication Year: 2001, Page(s):245 - 253 vol.1
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (749 KB) | HTML iconHTML

    As our early work, we proposed a data mining model for query refinement using Association Rules (ARs) mined among keywords of a large document database. In this paper, first, we explicitly identify principles of a data mining model for query refinement, and show that our model satisfies the principles. Second, we propose a mechanism to reduce the large number of ARs using a concept called "prime k... View full abstract»

    As a subset of SGML, XML (Extensible Markup Language) is becoming a dominant standard for representing data in the World Wide Web and therefore the efficient treatment of XML data is important for information transfer over a network. One way towards this goal is to integrate database technology into document management and bring the very nature of database systems into this area, such as query pro... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (868 KB) | HTML iconHTML

    While Web search engines can retrieve information on the Web for a specific topic, users have to step a long ordered list in order to locate the needed information, which is often tedious and less efficient. We propose a new link-based clustering approach to cluster search results returned from Web search engines by exploring both co-citation and coupling. Unlike document clustering algorithms in ...

    We address the problem of specifying Web searches and retrieving, filtering and rating Web pages so as to improve the relevance and quality of hits, based on the user's search intent and preferences. We present a methodology and architecture for an agent-based system, called WebSifter II, that captures the semantics of a user's decision-oriented search intent, transforms the semantic query into ta...

    With XML becoming a major standard for the exchange and sharing of data, many applications now rely on XML to publish and utilize Web data. Data sources (data owners), however often do not have the means to provide high performance query mechanisms, serving hundreds of thousands of client queries per day. Furthermore, it is too costly for them to maintain a secure Web information system infrastruc... View full abstract»

    XML is increasingly being adopted for information publishing on the World Wide Web. However, the underlying data is often stored in the relational databases. Some mechanism is needed to convert the relational data into XML data. In this work we employ a semantically rich semistructured data model, the object-relationship-attribute model for semistructured data, as a middleware to support the schem... View full abstract»

    While using an algebra that acts on sets of variable bindings for evaluating XML queries, the problem of constructing XML from these bindings arises. One approach is to define a powerful operator that is able to perform a complex construction of a representation of the XML result document. The drawback is that such an operator in its generality is hard to implement and disables algebraic optimizat... View full abstract»

    The World Wide Web (WWW) is becoming the most important system for delivering information. Search services on the WWW are becoming increasing popular among users because of the huge amount of data available and consequently it is difficult to retrieve and filter it. Several works have argued that traditional term-based search engines are not very useful since the resulting ranking depends on the p... View full abstract»

    Semistructured data has become prevalent with the growth of the Internet. The development of new web applications that require efficient design and maintenance of large amounts of data makes it increasingly important to design "good" semistructured databases to prevent data redundancy and updating anomalies. However, it is not easy, even impossible, for current semistructured data models to captur... View full abstract»
