    • Relevance Assessments and Retrieval System Evaluation 

      Salton, Gerard (Cornell University, 1968-09)
      Two widely used criteria for evaluating the effectiveness of information retrieval systems are, respectively, the recall and the precision. Since the determination of these measures is dependent on a distinction between ...
    • Search and Retrieval Experiments in Real-Time Information Retrieval 

      Salton, Gerard (Cornell University, 1968-02)
      Future operating document retrieval systems may be based on fully-automatic information analysis methods instead of manual indexing, and on real-time search procedures which allow the user to interact with the system during ...
    • Selective Text Traversal 

      Salton, Gerard; Singhal, Amit (Cornell University, 1995-09)
      In information retrieval and text processing, the size of the available databases and text collections has grown enormously in the past few years, and users find it difficult to cope with the amount of text that is potentially ...
    • Selective Text Utilization and Text Traversal 

      Salton, Gerard; Allan, James (Cornell University, 1993-07)
      Many large collections of full-text documents are currently stored in machine-readable form and processed automatically in various ways. These collections may include different types of documents, such as messages, ...
    • Selective Use of Full-Text Databases 

      Salton, Gerard; Allan, James; Buckley, Chris (Cornell University, 1992-08)
      Large files of natural-language text are now available for automatic processing in machine readable form. Such text files may include documents of textbook size, medium-size newspaper articles and short messages and mail ...
    • A Simple Syntactic Approach for the Generation of Indexing Phrases 

      Salton, Gerard; Zhao, Zhongnan; Buckley, Chris (Cornell University, 1990-07)
      A syntactic approach is described for generating indexing phrases usable for the content identification of natural-language texts. The phrase generation method is based on a simple language analysis system that determines ...
    • Some Notions about Information Retrieval in Automated Office Environments 

      Salton, Gerard (Cornell University, 1984-05)
      A substantial portion of the work required in office environments involves the processing of natural language texts. This note contains some ideas relating to the structure of natural language texts in office environments. ...
    • The State of Retrieval System Evaluation 

      Salton, Gerard (Cornell University, 1991-05)
      Substantial misgivings have been voiced over the years about the methodologies used to evaluate information retrieval procedures, and about the credibility of many of the available test results. In this note, an attempt ...
    • Suggestions for a Uniform Representation of Query and Record Content in Data Base and Document Retrieval 

      Salton, Gerard (Cornell University, 1979-01)
      A standard approach is introduced for the representation of information content in data base and document retrieval environments. The use of composite concept vectors representing individual information items leads to a ...
    • A Syntactic Approach to Automatic Book Indexing 

      Salton, Gerard (Cornell University, 1989-03)
      Automatic publishing systems are now widely used to produce books and documents of many types. As a result, large masses of text become available in machine readable form for automatic processing. This study describes ...
    • 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 ...
