    • A New Comparison Between Conventional Indexing (MEDLARS) andAutomatic Text Processing (SMART) 

      Salton, Gerard (Cornell University, 1971-12)
      A new testing process is described designed to compare conventional retrieval (MEDLARS) and automatic text analysis methods (SMART). The results obtained with a collection of documents chosen independently of either SMART ...
    • A Note About Information Science Research 

      Salton, Gerard (Cornell University, 1984-09)
      This note deals with the relationship between information science research and practice. The impression that the field is moribund and that the research output is uniformly inferior is not supported by an examination of ...
    • A Note on Term Weighting and Text Matching 

      Salton, Gerard; Buckley, Chris (Cornell University, 1990-10)
      In information retrieval, it is not uncommon to be faced with large collections of unrestricted natural-language text. In such circumstances, the text analysis and retrieval operations must be based mainly on a study of ...
    • On the Application of Syntactic Methodologies in Automatic Text Analysis 

      Salton, Gerard; Smith, Maria (Cornell University, 1988-12)
      This study summarizes various linguistic approaches proposed for document analysis in information retrieval environments. Included are standard syntactic methods to generate complex content identifiers, and the use of ...
    • On the Automatic Generation of Content Links in Hypertext 

      Salton, Gerard; Buckley, Chris (Cornell University, 1989-04)
      Text structuring systems that provide links between text portions have been widely proposed as aids for text preparation and text manipulation. In principle, it is easy to follow available links between related text ...
    • On the Role of Words and Phrases in Automatic Text Analysis 

      Salton, Gerard; Wong, A. (Cornell University, 1975-06)
      One of the most crucial operations in automatic information retrieval is the assignment to written texts and documents of appropriate identifiers, capable of representing information content for search and retrieval ...
    • On the Specification of Term Values in Automatic Indexing 

      Salton, Gerard; Yang, C.S. (Cornell University, 1973-06)
      The existing practice in automatic indexing is reviewed, and it is shown that the standard theories for the specification of term values (or weights) are not adequate. New techniques are introduced for the assignment of ...
    • On the Use of Clustered File Organization in Information Search and Retrieval 

      Salton, Gerard; Araya, Jose E. (Cornell University, 1989-04)
      In modern retrieval environments, collection searches are normally conducted on-line under user control. Iterative collection searches can then be performed where tentative queries are initially processed, to be successively ...
    • On the Use of Spreading Activation Methods in Automatic Information Retrieval 

      Salton, Gerard; Buckley, Chris (Cornell University, 1988-04)
      Spreading activation methods have been recommended in information retrieval to expand the search vocabulary and to complement the retrieved document sets. The spreading activation strategy is reminiscent of earlier ...
    • Parallel Computations in Information Retrieval 

      Salton, Gerard; Bergmark, D. (Cornell University, 1980-09)
      Conventional information retrieval processes are largely based on data movement, pointer manipulations and integer arithmetic; more refined retrieval algorithms may in addition benefit from substantial computational ...
    • Parallel Text Search Methods 

      Salton, Gerard; Buckley, Chris (Cornell University, 1987-04)
      An evaluation of recently proposed parallel text search methods does not support the notion that the parallel methods provide large-scale gains in either retrieval effectiveness or efficiency, compared with alternative ...
    • Pivoted Document Length Normalization 

      Singhal, Amit; Buckley, Chris; Mitra, Mandar; Salton, Gerard (Cornell University, 1995-11)
      Document length normalization is an important aspect of term weight assignment in an automatic information retrieval system. In this study, we observe that a normalization scheme that retrieves documents of all lengths ...
    • Precision Weighting - An Effective Automatic Indexing Method 

      Yu, C. T.; Salton, Gerard (Cornell University, 1975-03)
      A great many automatic indexing methods have been implemented and evaluated over the last few years, and automatic procedures comparable in effectiveness to conventional manual ones are now easy to generate. Two drawbacks ...
    • A Progress Report on Automatic Information Retrieval 

      Salton, Gerard (Cornell University, 1979-02)
      This study is a state-of-the-art report of work in automatic information retrieval. Various enhancements of operational on-line retrieval systems are described such as the utilization of special front-end devices providing ...
    • Proposals for a Dynamic Library 

      Salton, Gerard (Cornell University, 1972-08)
      The current library environment is first examined, and an attempt is made to explain why the standard approaches to the library problem have been less productive than had been anticipated. A new design is then introduced ...
    • 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, ...
