    XML (eXtensible Mark-up Language) is able to represent any kind of structured or semi-structured document, such as papers, Web pages, database schemas and instances, style sheets, etc. However, the tree structure of XML documents, induced by mark-up nesting, does not provide a sufficiently expressive and general conceptual model of data in the documents, particularly when multiple source documents...

    The diversity and availability of information sources on the World Wide Web has set the stage for integration and reuse at an unparalleled scale. There remain obstacles to exploiting the extent of the Web's resources in a consistent, scalable and maintainable fashion. The autonomy and volatility of Web sources complicates maintaining wrappers consistent with the requirements of the data's target a... View full abstract»

  • Exploiting hierarchical global views for query reformulation

    Publication Year: 1999, Page(s):91 - 98
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (124 KB)

    In this paper, we introduce the concept of hierarchical global views to support query reformulation in mediator architectures. In particular, we show how the characteristics of a cluster hierarchy can be exploited in the query reformulation phase in order to comply with the user information requirements, expressed in terms of answer precision and recall under response time constraints, which are w...

  • A paradigm for detecting cycles in large data sets via fuzzy mining

    Traditional data mining algorithms identify associations in data that are not explicit. Cycle mining algorithms identify meta-patterns of these associations depicting inferences forming chains of positive and negative rule dependencies. This paper describes a formal paradigm for cycle mining using fuzzy techniques. To handle cycle mining of large data sets, which are inherently noisy, we present t... View full abstract»

  • Knowledge-association networks for system design

    Publication Year: 1999, Page(s):131 - 138
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (760 KB)

    Knowledge-association networks, a new framework for a knowledge base for automatic system design, is proposed. With this framework, knowledge base developers can easily avoid verbose descriptions, errors and inconsistencies, and can reduce the computational complexity in automatic system design. The networks focus on the associations among pieces of knowledge about system components. The associati... View full abstract»

    Enterprise databases comprise multiple local databases that exchange information. The component databases will rarely have the same native form, so one must map between the native interfaces of the data suppliers and the recipients. An SQL view is a convenient and powerful way to define this map, because it provides not just an evaluation mechanism, but also query, and (to some degree) update and ... View full abstract»

    Data products (macrodata or tabular data and micro-data or raw data records), are designed to inform public or business policy, and research or public information. Securing these products against unauthorized accesses has been a long-term goal of the database security research community and the government statistical agencies. Solutions to this problem require combining several techniques and mech... View full abstract»

    In recent years, there has been much work on the retrieval of information from multimedia repositories. In particular, researchers have shown a great deal of interest in merging the results returned by multiple multimedia repositories into a single result. This task is challenging due to the heterogeneities among such systems, e.g. differences in the indexing methods and similarity functions emplo... View full abstract»

  • Mining quantitative association rules under inequality constraints

    In the past several years, there has been much active work in developing algorithms for mining association rules. However, in many real-life situations, not all association rules are of interest to the user. A user may want to find association rules which satisfy a given inequality constraint for a set of quantitative items. In other words, users are more interested in the subsets of those associa...

    The complexity and richness of geospatial data and the difficulty of their representation create specific problems for the interoperability of geographic information systems. This paper proposes the creation of software components from ontologies as a way to share knowledge and data. These software components are derived from ontologies using an object-oriented mapping. The translation of ontologi... View full abstract»

  • Software agents and workflows meet CCISs interoperability

    Publication Year: 1999, Page(s):139 - 143
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (156 KB)

    A command-and-control information system (CCIS) is a military application that provides information to be used by a commander. The use of a single CCIS is rather easy. However, the operation becomes much more complex when several CCISs, generally distributed and heterogeneous, are required. As a solution, we intend to set up software agents that support the interoperability of these CCISs. The dev... View full abstract»

    We describe an approach to usage based Web personalization taking into account both the offline tasks related to the mining of usage data, and the online process of automatic Web page customization based on the mined knowledge. Specifically, we propose an effective technique for capturing common user profiles based on association rule discovery and usage based clustering. We also propose technique... View full abstract»

    A melody-based similarity computation algorithm for musical information is proposed in which melodies are used as the basic features for calculating the similarity between two music files. In multimedia information systems, in order to retrieve the needed information appropriately, content-based retrieval strategies are used which are based on the similarity between the user's query and the stored...

    Although the Euclidean distance has been the most popular similarity measure in sequence databases, recent techniques prefer to use high-cost distance functions such as the time warping distance and the editing distance for wider applicability. However, if these distance functions are applied to the retrieval of similar subsequences, the number of subsequences to be inspected during the search is ... View full abstract»

  • On ranking and organizing Web query results

    With the explosive growth of the WWW, most searches retrieve a large number of documents. The query results returned have no aggregate structure; thus, it is difficult to forage for relevant pages. We argue that organization of Web query results is essential to the user in terms of usability of query results. In addition, how the query results are organized has a great impact on the ranking scheme... View full abstract»

    In this paper, we present our concept and design of a general film model that represents the structural, semantic and syntactic elements of film. The purpose of this model is to serve as a basis for film video annotation and subsequent retrieval. It is informed by contemporary film theory and analysis to adequately represent the film content and its attributes. The implementation of such a model e... View full abstract»

    Much of the data we deal with every day is organized hierarchically: file systems, library classification schemes and yellow page categories are salient examples. Business data too, benefits from a hierarchical organization, and indeed the hierarchical data model was quite prevalent thirty years ago. Due to the recently increased importance of X.500/LDAP directories, which are hierarchical, and th... View full abstract»

    As an alternative to search capability, many search engines are providing directory servers containing categorized Web documents for users to navigate and browse through. We are investigating three issues in portal site construction given a large collection of categorized Web documents: (1) distillation of important topics for each category of documents; (2) distillation of important documents/sit...
