  • Efficient content-based indexing of large image databases 
    Kabuka Essam A. El-Kwae/Mansur R.
    Large image databases have emerged in various applications in recent years. A prime requisite of these databases is the means by which their contents can be indexed and retrieved. A multilevel signature file called the Two ...
  • Improving the Effectiveness of Information Retrieval with Local Context Analysis 
    Xu Jinxi; Technologies Bbn; Croft W Bruce
    Techniques for automatic query expansion have been extensively studied in information retrieval research as a means of addressing the word mismatch between queries and documents. These techniques can be categorized as ...
  • Chimera: Hypermedia for Heterogeneous Software Development Environments 
    Anderson Kenneth M; Taylor Richard N; Whitehead E James; Anderson K M; Taylor R N; Whitehead E J (2000)
    Emerging software development environments are characterized by heterogeneity: they are composed of diverse object stores, user interfaces, and tools. This paper presents an approach for providing hypermedia services in ...
  • Evaluating the Performance of Distributed Architectures for Information Retrieval Using a Variety of Workloads 
    Cahoon Brendon; Mckinley Kathryn S; Mckinley K S
    The information explosion across the Internet and elsewhere offers access to an increasing number of document collections. In order for users to effectively access these collections, information retrieval (IR) systems must ...
  • Beyond Intratransaction Association Analysis: Mining Multidimensional Intertransaction Association Rules 
    Lu Hongjun; Kong Hong; Lu H (2001)
    In this paper, we extend the scope of mining association rules from traditional single-dimensional intratransaction associations, to multidimensional intertransaction associations. Intratransaction associations are the ...
  • Model-Driven Development of Web Applications: The Autoweb System 
    Fraternali Piero; Paolini Paolo; Milano Politecnico Di (2001)
    This paper describes a methodology for the development of WWW applications and a tool environment specifically tailored for the methodology. The methodology and the development environment are based upon models and techniques ...
  • Beneath the Surface of Organizational Processes: A Social Representation Framework for Business Process Redesign 
    Katzenstein Gary; Kong Hong; Lerch F Javier (2001)
    This paper raises the question, " What is an effective representation framework for organizational process redesign? " By combining our knowledge of existing process models with data from a field study, the paper develops ...
  • Shortest-Substring Retrieval and Ranking 
    Clarke Charles L A; Cormack Gordon V
    We present a model for arbitrary passage retrieval using Boolean queries. The model is applied to the task of ranking documents, or other structural elements, in the order of their expected relevance. Features such as ...
  • The Maximum Entropy Approach and Probabilistic IR Models 
    Greiff Warren R; Ponte Jay M (2000)
    This paper takes a fresh look at modeling approaches to information retrieval that have been the basis of much of the probabilistically motivated IR research over the last 20 years. We shall adopt a subjectivist Bayesian ...
  • Knowledge Encapsulation for Focused Search from Pervasive Devices 
    Aridor Yariv; Carmel David; Maarek Yoelle S; Soffer Aya (2002)
    Mobile knowledge seekers often need access to information on the Web during a meeting or on the road, while away from their desktop. A common practice today is to use pervasive devices such as Personal Digital Assistants ...
  • Improving Retrieval Feedback with Multiple Term-Ranking Function Combination 
    Carpineto Claudio; Romano Giovanni; Bordoni Fondazione Ugo; Giannini Vittorio; A Telecomunicazioni S P (2002)
    In this article we consider methods for automatic query expansion from top retrieved documents (i.e., retrieval feedback) that make use of various functions for scoring expansion terms within Rocchio's classical reweighting ...
  • Collection Statistics for Fast Duplicate Document Detection 
    Chowdhury Abdur; Frieder Ophir; Grossman David; Mccabe Mary Catherine (2002)
    We present a new algorithm for duplicate document detection that uses collection statistics. We compare our approach with the state-of-the-art approach using multiple collections. These collections include a 30 MB 18,577 ...
  • Efficient Web Browsing on Handheld Devices Using Page and Form Summarization 
    Buyukkokten Orkut; Kaljuvee Oliver; Garcia-Molina Hector; Paepcke Andreas; Winograd Terry (2002)
    We present a design and implementation for displaying and manipulating HTML pages on small handheld devices such as personal digital assistants (PDAs), or cellular phones. We introduce methods for summarizing parts of Web ...
  • Peer-to-Peer Data Trading to Preserve Information 
    Cooper Brian F; Garcia-Molina Hector (2002)
    Data archiving systems rely on replication to preserve information. This paper discusses how a network of autonomous archiving sites can trade data to achieve the most reliable replication. A series of binary trades among ...
  • Theory of Keyblock-Based Image Retrieval 
    Zhu Lei; Rao Aibing; Zhang Aidong (2002)
    The success of text-based retrieval motivates us to investigate analogous techniques which can support the querying and browsing of image data. However, images differ significantly from text both syntactically and semantically ...
  • Burst Tries: A Fast, Efficient Data Structure for String Keys 
    Heinz Steffen; Zobel Justin; Williams Hugh E (2002)
    Many applications depend on efficient management of large sets of distinct strings in memory. For example, during index construction for text databases a record is held for each distinct word in the text, containing the ...
  • Placing Search in Context: The Concept Revisited 
    Finkelstein Lev; Gabrilovich Evgeniy; Matias Yossi; Rivlin Ehud; Solan Zach; Wolfman Gadi; Ruppin Eytan (2002)
    Keyword-based search engines are in widespread use today as a popular means for Web-based information retrieval. Although such systems seem deceptively simple, a considerable amount of skill is required in order to satisfy ...
  • PicASHOW: Pictorial Authority Search by Hyperlinks On the Web 
    Lempel Ronny; Lempel R; Lempel R; Soffer A (2002)
    We describe PicASHOW, a fully automated WWW image retrieval system that is based on several link-structure analyzing algorithms. Our basic premise is that a page p displays (or links to) an image when the author of p ...
  • A Semantic Network-Based Design Methodology for XML Documents Semantic Network-Based Design Methodology 
    Feng Ling; Chang Elizabeth (2002)
    The eXtensible Markup Language (XML) is fast emerging as the dominant standard for describing and interchanging data among various systems and databases on the Internet. It offers the Document Type Definition (DTD) as a ...
  • When Experts Agree: Using Non-Affiliated Experts to Rank Popular Topics 
    Bharat Krishna; Mihaila George A (2002)
    In response to a query, a search engine returns a ranked list of documents. If the query is about a popular topic (i.e., it matches many documents), then the returned list is usually too long to view fully. Studies show ...
