    • Term Relevance Weights in On-Line Information Retrieval 

      Salton, Gerard; Waldstein, R. K. (Cornell University, 1977-07)
      Considerable evidence exists to show that the use of term relevance weights is beneficial in interactive information retrieval. Various term weighting systems are reviewed. An experiment is then described in which ...
    • Term Weighting Approaches in Automatic Text Retrieval 

      Salton, Gerard; Buckley, Chris (Cornell University, 1987-11)
      The experimental evidence accumulated over the past 20 years indicates that textindexing systems based on the assignment of appropriately weighted single terms produce retrieval results that are superior to those obtainable ...
    • Text Linking and Retrieval Experiments for Textbook Components 

      Salton, Gerard; Buckley, Chris; Zhao, Zhongnan (Cornell University, 1990-05)
      Experiments are described designed to retrieve individual paragraphs of textbook material in answer to user-submitted queries. The retrieval strategies are based on the global comparison of paragraph texts, as well as ...
    • A Theory of Indexing 

      Salton, Gerard (Cornell University, 1974-03)
      THe content analysis, or indexing problem, is fundamental in information storage and retrieval. Several automatic procedures are examined for the assignment of significance values to the terms, or keywords, identifying ...
    • A Theory of Term Importance in Automatic Text Analysis 

      Salton, Gerard; Yang, C. S.; Yu, C. T. (Cornell University, 1974-07)
      Most existing automatic content analysis and indexing techniques are based on word frequency characteristics applied largely in an ad hoc manner. Contradictory requirements arise in this connection, in that terms exhibiting ...
    • The Use of Extended Boolean Logic in Information Retrieval 

      Salton, Gerard (Cornell University, 1984-01)
      An extended Boolean retrieval strategy has previously been introduced in which the individual Boolean operators can be treated more or less strictly, depending on the perceived strength of association of the query terms. ...
    • The Use of Standardized Documentary Data in AutomaticInformation Dissemination 

      Salton, Gerard (Cornell University, 1968-03)
      It is likely that future operating information retrieval systems may be based on automatic information analysis methods instead of manual indexing, and on search procedures which allow the user to interact with the system ...
    • User-System Interaction in Automatic Information Retrieval 

      Salton, Gerard; Crouch, Donald B. (Cornell University, 1989-05)
      Information retrieval activities are now routinely conducted on-line under the control of search intermediaries or end users. Examples are presented of advanced aids that permit the user to control the search process and ...
    • A Vector Space Model for Automatic Indexing 

      Salton, Gerard; Wong, A.; Yang, C. S. (Cornell University, 1974-07)
      In a document retieval, or other pattern matching environment where stored entities (documents) are compared with each other, or with incoming patterns (search requests), it appears that the best indexing (property) space ...
