    We deal with information system design when several responsibilities share a common subset of information. First, we show how to define information overlap situations between these responsibilities. Then we focus on these situations in order to understand how the responsibility areas can avoid information co-ordination misunderstandings. The study of these situations shows how to define the inform... View full abstract»

    Scientific simulations evolve constantly. Both the logical organization of the underlying database and the scientist's view of data may change rapidly. The underlying DBMS must provide appropriate support for the evolution of scientific simulations, their rapidly increasing computational intensity, as well as the growing volumes and dimensionality of scientific data. ADAMS is a dynamic and scalabl... View full abstract»

    Current information retrieval (IR) is mainly focused on retrieving documents that have not been read before, and to our knowledge, no research has been conducted for querying against already read documents. For such documents, querying based on visual memory is often helpful. In this paper, a framework for querying structured documents by making use of human visual memory is proposed, and an index...

  • New techniques for the discovery of logical documents in Web

    Publication Year: 1999, Page(s):125 - 132
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (352 KB)

    We propose a method of identifying logical documents in Web data. Pages in Web data are sometimes designed for presentation and do not always reflect logical structure, while a logical document is a data unit representing logical structure. One logical document often corresponds to a connected subgraph consisting of multiple pages. Therefore, for various Web data processing that should capture log... View full abstract»

    When multimedia DBMS services video data, the storage system for it needs a large disk bandwidth in order to provide more users simultaneously with the real time retrieval requests. So, the storage system of a multimedia DBMS generally has the structure of a disk array which consists of multiple disks. When the storage system serves multiple video stream requests, its bottlenecks come from the see... View full abstract»

    Most Internet search engines are keyword based. They are not efficient for the queries where geographical location is important, such as finding hotels close to a place of interest. A natural interface for spatial searching is a map, which can be used not only to display locations of search results but also to assist forming search conditions. A map-based search engine requires a well-designed vis... View full abstract»

  • An approximation method for extracting typical classes from semistructured data

    Publication Year: 1999, Page(s):197 - 200
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (176 KB)

    We consider a class extraction problem over semistructured data. A class C is extracted by grouping objects having similar (not necessarily identical) sets of properties into C, where the set of properties of C is the union of those of the objects in C. Let C be an extracted class and o be an object in C. If C has property P but o has no property P value, then P is null within o. An extracted clas... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (344 KB)

    The I/O cost of spatial join processing could be very high due to the large sizes of spatial objects and the large number of spatial objects involved. Spatial joins are usually performed by the filter-and-refinement approach. Although there exists a variety of algorithms for realizing the filter step of the join processing for large spatial data sets, not much research has been done to improve the... View full abstract»

    On-line analytical processing (OLAP) queries can take hours or even days to execute on very large data warehouses. Therefore, there is a need to employ techniques that can facilitate efficient execution of these queries. The data partitioning concept that has been studied in the context of relational databases aims to reduce query execution time and facilitate the parallel execution of queries. In...

    Cooperative work is of long-duration, follows certain workflows, and presupposes information exchange among participants. Conversely, traditional database systems manage data essentially by isolation of transactions and by the assumption that each transaction maintains the consistency of the database. To overcome this gap, this paper proposes a multiversion data model, which both records revisions... View full abstract»
