  • Exploiting Hierarchical Domain Structure to Compute Similarity 
    Ganesan Prasanna; Garcia-Molina Hector; Widom Jennifer (1904)
    The notion of similarity between objects finds use in many contexts, for example, in search engines, collaborative filtering, and clustering. Objects being compared often are modeled as sets, with their similarity traditionally ...
  • QProber: A System for Automatic Classification of Hidden-Web Databases 
    Gravano Luis; Ipeirotis Panagiotis G (2003)
    The contents of many valuable Web-accessible databases are only available through search interfaces and are hence invisible to traditional Web " crawlers. " Recently, commercial Web sites have started to manually organize ...
  • CLAIRE: A Modular Support Vector Image Indexing and Classification System 
    Tsai Chih-Fong; Mcgarry Ken; Tait John (2006)
    Many users of image retrieval systems would prefer to express initial queries using keywords. However, manual keyword indexing is very time-consuming. Therefore, a content-based image retrieval system which can automatically ...
  • Query Enrichment for Web-Query Classification Query Enrichment for Web-Query Classification 
    Shen Dou; Pan Rong; Kong Hong; Research Microsoft; Asia; Junfeng Jeffrey; Wu Kangheng; Yin Jie; Yang Qiang; Kong Hong; Shen D; Pan R; Pan J J; Wu K; Yin J; Yang Q (2006)
    Web-search queries are typically short and ambiguous. To classify these queries into certain target categories is a difficult but important problem. In this article, we present a new technique called query enrichment, which ...
  • iVIBRATE: Interactive Visualization-Based Framework for Clustering Large Datasets 
    Chen Keke; Liu Ling; Chen L; Liu; Chen @bullet K; Additional L Liu (2006)

  • Enhancing Relevance Feedback in Image Retrieval Using Unlabeled Data 
    Zhou Zhi-Hua; Chen Ke-Jia; Dai Hong-Bin (2006)
    Relevance feedback is an effective scheme bridging the gap between high-level semantics and low-level features in content-based image retrieval (CBIR). In contrast to previous methods which rely on labeled images provided ...
  • A Large Scale, Corpus-Based Approach for Automatically Disambiguating Biomedical Abbreviations Automatically Disambiguating Biomedical Abbreviations 
    Yu Hong; Wilbur John (2006)
