  • Applying Associative Retrieval Techniques to Alleviate the Sparsity Problem in Collaborative Filtering Associative Retrieval Techniques for the Sparsity Problem • 
    Huang Zan; Chen Hsinchun; Zeng Daniel (2004)
    Recommender systems are being widely applied in many application settings to suggest products, services, and information items to potential consumers. Collaborative filtering, the most successful recommendation approach, ...
  • Evaluating Collaborative Filtering Recommender Systems 
    Herlocker Jonathan L; Konstan Joseph A; Terveen Loren G; Riedl John T (2004)
    Recommender systems have been evaluated in many, often incomparable, ways. In this article, we review the key decisions in evaluating collaborative filtering recommender systems: the user tasks being evaluated, the types ...
  • Anchor Text Mining for Translation of Web Queries: A Transitive Translation Approach Anchor Text Mining for Translation of Web Queries 
    Lu Wen-Hsiang; Lu W.-H; Lee H.-J (2004)
    To discover translation knowledge in diverse data resources on the Web, this article proposes an effective approach to finding translation equivalents of query terms and constructing multilingual lexicons through the mining ...
  • A Study of Smoothing Methods for Language Models Applied to Information Retrieval 
    Zhai Chengxiang; Lafferty John; Zhai @bullet C; Lafferty J (2004)
    Language modeling approaches to information retrieval are attractive and promising because they connect the problem of retrieval with that of language model estimation, which has been studied extensively in other application ...
  • Item-Based Top-N Recommendation Algorithms 
    Deshpande Mukund; Karypis George; Karypis G; Deshpande M; Karypis G (2004)
    The explosive growth of the worldwide web and the emergence of e-commerce has led to the development of recommender systems—a personalized information filtering technology used to identify a set of items that will be of ...
  • SALSA: The Stochastic Approach for Link- Structure Analysis 
    Lempel R; Moran S
    Today, when searching for information on the WWW, one usually performs a query through a term-based search engine. These engines return, as the query's result, a list of Web pages whose contents matches the query. For ...
  • WebQuilt: A Proxy-based Approach to Remote Web Usability Testing 
    Hong Jason I; Heer Jeffrey; Waterson Sarah; Landay James A (2001)
    WebQuilt is a web logging and visualization system that helps web design teams run usability tests (both local and remote) and analyze the collected data. Logging is done through a proxy, overcoming many of the problems ...
  • A Statechart-Based Model for Hypermedia Applications 
    Ferreira Maria Cristina; Oliveira De (1910)
    This paper presents a formal definition for HMBS (Hypermedia Model Based on Statecharts). HMBS uses the structure and execution semantics of statecharts to specify both the structural organization and the browsing semantics ...
  • An Information-Theoretic Approach to Automatic Query Expansion 
    Fondazione Claudio Carpineto; Bordoni Ugo; Mori Renato De; Romano Giovanni; Bordoni Fondazione Ugo; Bigi Brigitte
    Techniques for automatic query expansion from top retrieved documents have shown promise for improving retrieval effectiveness on large collections; however, they often rely on an empirical ground, and there is a shortage ...
  • Building a Distributed Full-Text Index for the Web 
    Melnik Sergey; Raghavan Sriram; Yang Beverly; Garcia-Molina Hector (2001)
    We identify crucial design issues in building a distributed inverted index for a large collection of Web pages. We introduce a novel pipelining technique for structuring the core index-building system that substantially ...
  • On the Design of a Learning Crawler for Topical Resource Discovery On the Design of a Learning Crawler for Topical Resource Discovery 
    Aggarwal Charu C; Yu Philip S (2001)
    In recent years, the World Wide Web has shown enormous growth in size. Vast repositories of information are available on practically every possible topic. In such cases, it is valuable to perform topical resource discovery ...
  • Genre Taxonomy: A Knowledge Repository of Communicative Actions 
    Yoshioka Takeshi; Co Fuji Xerox; Herman Ltd George; Yates Joanne; Orlikowski Wanda (2002)
    We propose a genre taxonomy as a knowledge repository of communicative structures or " typified actions " enacted by organizational members. The genre taxonomy is intended to help people make sense of diverse types of ...
  • Application of Aboutness to Functional Benchmarking in Information Retrieval 
    Wong Kam-Fai; Wong K.-F; Cheng C.-H; Song D; Bruza P (2002)
    Experimental approaches are widely employed to benchmark the performance of an information retrieval (IR) system. Measurements in terms of recall and precision are computed as performance indicators. Although they are good ...
  • A Highly Scalable and Effective Method for Metasearch A Highly Scalable Method for Metasearch 
    Meng Weiyi; Wu Zonghuan; Meng W; Wu Z; Li Z; Yu C (2001)
    A metasearch engine is a system that supports unified access to multiple local search engines. Database selection is one of the main challenges in building a large-scale metasearch engine. The problem is to efficiently and ...
  • Computing Graphical Queries over XML Data 
    Comai Sara; Milano Politecnico Di (2002)
    The rapid evolution of XML from a mere data exchange format to a universal syntax for encoding domain-specific information raises the need for new query languages specifically conceived to address the characteristics of ...
  • Query-Based Sampling of Text Databases 
    Connell Jamie Callan/Margaret
    The proliferation of searchable text databases on corporate networks and the Internet causes a database selection problem for many people. Algorithms such as gGlOSS and CORI can automatically select which text databases ...
  • Approximate Spatio-Temporal Retrieval 
    Papadias Dimitris; Kong Hong; Cwi Nikos Mamoulis; Delis Vasilis (1910)
    This paper proposes a framework for the handling of spatio-temporal queries with inexact matches, using the concept of relation similarity. We initially describe a binary string encoding for 1D relations that permits the ...
  • Fast and Flexible Word Searching on Compressed Text 
    Silva Edleno; Moura De; Baeza-Yates R
    We present a fast compression and decompression technique for natural language texts. The novelties are that (1) decompression of arbitrary portions of the text can be done very efficiently, (2) exact search for words and ...
  • Scaling Question Answering to the Web 
    Kwok Cody; Etzioni Oren; Weld Daniel S (2001)
    The wealth of information on the web makes it an attractive resource for seeking quick answers to simple, factual questions such as " who was the first American in space? " or " what is the second tallest mountain in the ...
  • Extending Document Management Systems with User-Specific Active Properties 
    Dourish Paul; Edwards W Keith; Lamarca Anthony; Lamping John; Petersen Karin; Salisbury Michael; Terry Douglas B; Thornton James
