    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»

    We consider the problem of automatically visualizing information contained in a database and propose a framework that addresses the issues involved. Our approach does not depend on the particular data model used, the size of the instance set, or the nature of the data being represented. The aim of the framework is to produce a correct, complete, and possibly highly effective visual representation.... View full abstract»

    As the amount of data representing the real world increases, it is essential to manage it as collections of small components in spatial databases. The basic procedure of producing virtual spaces dynamically is realized by retrieving and visualizing dynamically spatial data stored in spatial databases using the rule of LoD (levels of detail). This paper discusses a principle of “time” e... View full abstract»

    We address the problem of choosing synchronous data combinations from periodically generated data sequences (PGDAs). In real time systems, PGDAs play a major role. When integrating PGDAs generated from various information sources, we face the problem of choosing which data combinations to use, since different PGDAs, in general, have different data generation intervals. A data combination is define... View full abstract»

    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»

  • Parallel spatial join algorithms using grid files

    Publication Year: 1999, Page(s):226 - 234
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (404 KB)

    The most costly spatial operation in spatial databases is a spatial join which combines objects from two data sets based on spatial predicates such as intersects or contains. Even if the execution time of sequential spatial join processing has improved over the last few years, the response time is far from meeting the requirements of interactive users. In this paper, we have designed two kinds of ... View full abstract»

    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»

    When we search from a huge amount of documents, we often specify several keywords and use conjunctive queries to narrow the result of the search. Though the searched documents contain all keywords, positions of the keywords are usually not considered. As the result, the search result contains some meaningless documents. It is therefore effective to rank documents according to proximity of keywords... View full abstract»

    Many business processes which are abstracted to workflows have time constraints such that their processing should be completed within their deadlines. New time management technologies are therefore required for high workflow throughput which can maximize the number of workflow instances satisfying their deadlines. In this paper we propose an efficient deadline assignment method and validate its us... View full abstract»

    It is possible to acquire human motion as 3-dimensional time series data by the development of sensing technology in recent years. The DP matching method is well known for recognition of time series data such as voice. The similarity between two time series data can be measured by DP matching. However, since human motion data consists of multiple mutually-synchronized time series data, the similar... View full abstract»
