    Summary form only given. This presentation is an exploration of the next generation computing based on the confluence of radical and coincidental changes in economics, business, and technology. Whereas technology is a key enabler of change, it is and is the servant, not the master. Without a depth of understanding of this enabling role and the content in which technology serves, technology can be ... View full abstract»

    Summary form only given. We are interested in Workflow Management Systems (WFMS), and particularly, in Resource Management (RM) of WFMS. A WFMS consists of coordinating executions of multiple activities, instructing who (resource) do what (activity) and when. The "when" part is taken care of by the workflow engine which orders the executions of activities based on a process definition. The "who" p... View full abstract»

  • Data Mining from an Al Perspective

    Publication Year: 1999, Page(s): 186
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (75 KB)

    Summary form only given, as follows. Data Mining, or Knowledge Discovery in Databases as it is also called, is claimed as an offspring by three disciplines: databases, statistics, and the machine learning subfield of artificial intelligence. (The term originated in statistics with distinctly pejorative overtones - data mining was characterized as fossicking in data without a guiding model.) Statis... View full abstract»

    Summary form only given. The last few years have witnessed a significant increase in the use of databases for complex data analysis (OLAP) applications. These applications often require very quick responses from the DBMS. However, they also involve complex queries on large volumes of data. Despite significant improvement in database support for OLAP over the last few years, most DBMSs still fall s... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (87 KB)

    Summary form only given. Data warehouses (DW) are built by gathering information from several information sources (IS) and integrating it into one repository customized to users' needs. ISs are typically owned by different information providers and hence are independent and autonomous. This implies they will update their data and schemas independently and without any concern for how this may affec... View full abstract»

    Presents parallel algorithms for building decision-tree classifiers on shared-memory multiprocessor (SMP) systems. The proposed algorithms span the gamut of data and task parallelism. The data parallelism is based on attribute scheduling among processors. This basic scheme is extended with task pipelining and dynamic load balancing to yield faster implementations. The task-parallel approach uses d... View full abstract»

    Cited by:  Papers (66)  |  Patents (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (140 KB)

    Constraint-based rule miners find all rules in a given dataset meeting user-specified constraints such as minimum support and confidence. We describe a new algorithm that directly exploits all user-specified constraints including minimum support, minimum confidence, and a new constraint that ensures every mined rule offers a predictive advantage over any of its simplifications. Our algorithm maint... View full abstract»

    When constructing a large-scale database system, data replication is useful to give users efficient access to that data. However for databases with a very large number of replica sites, using traditional networking concurrency control protocols makes communication too costly for practical use. In this paper we propose a new protocol called ECHO for concurrency control of replica data distributed o... View full abstract»

    Nowadays, structured data such as sales and business forms are stored in data warehouses for decision makers to use. Further, unstructured data such as emails, HTML texts, images, videos, and office documents are increasingly accumulated in personal computer storage due to spread of mailing, WWW, and word processing. Such unstructured data, or what we call multimedia documents, are larger in volum... View full abstract»

    We develop a data integration approach for the efficient evaluation of queries over autonomous source databases. The approach is based on some novel applications and extensions of constraint database techniques. We assume the existence of a global database schema. The contents of each data source are described using a set of constraint tuples over the global schema; each such tuple indicates possi... View full abstract»

    In this paper we present an online method for managing a goal-oriented buffer partitioning in the distributed memory of a network of workstations. Our algorithm implements a feedback mechanism which dynamically changes the sizes of dedicated buffer areas and thereby the buffer hit rate for the different classes in such a way that user-specified response time goals are satisfied. The aggregated siz... View full abstract»

    We measure the performance of several cooperative caching policies for a database with hot spots. The workload consists of queries and append-only update transactions, and is modeled after a financial database of stock (historical) trading information. We show that cooperative caching is effective for this application. We show that selecting the correct set of peer servers when servicing a cache m... View full abstract»

    Spatial data mining presents new challenges due to the large size of spatial data, the complexity of spatial data types, and the special nature of spatial access methods. Most research in this area has focused on efficient query processing of static data. This paper introduces an active spatial data mining approach which extends the current spatial data mining algorithms to efficiently support use... View full abstract»

    Extensibility and high query performance are important requirements of advanced large scale information systems since complex data analysis often requires the use of application-specific operations that have to be introduced by the user issuing the query. Towards the goal of supporting automatic parallelization of queries containing complex user-defined evaluators in an extensible DBMS, we devised... View full abstract»

    To adequately support text, image, spatial, message and other complex forms of data, modern database management systems must provide an extensive set of data integration features. The emerging object-relational database systems provide features for defining, storing, updating, indexing, and retrieving complex data types with full transaction semantics. The author describes these features in the co... View full abstract»

    Studies similarity queries for time series data, where similarity is defined in terms of a set of linear transformations on the Fourier series representation of a sequence. We have shown in an earlier work that this set of transformations is rich enough to formulate operations such as moving average and time scaling. In this paper, we present a new algorithm for processing queries that define simi... View full abstract»

    Many applications require the storage and management of large databases of 2D objects. One of the important functionalities required by all of these applications is the capability to find objects in a database that match a given object. We concentrate on whole matching queries, in which a query object is compared with a set of objects to find the ones that are either exactly identical or similar t... View full abstract»
