  • Binary
  • A special retrieval file including arrays of binary coded elements is produced and maintained from the information content of the base data file. (patents.com)
  • To locate any particular desired record, the retrieval file is first searched by identifying and selecting those arrays representing desired predetermined identifiable characteristics of language structure and comparing the binary values of respectively corresponding elements in the selected arrays thus identifying which records in the base data file have all the desired predetermined identifiable characteristics of language structure. (patents.com)
  • Binary Independence Model Probabilistic relevance model on which is based the okapi (BM25) relevance function Uncertain inference Language models Divergence-from-randomness model Latent Dirichlet allocation Feature-based retrieval models view documents as vectors of values of feature functions (or just features) and seek the best way to combine these features into a single relevance score, typically by learning to rank methods. (wikipedia.org)
  • characteristic
  • Each array of the retrieval file corresponds to a particular predetermined identifiable characteristic of language structure potentially present in or associated with the set of records concerned and each element in such an array corresponds to and is representative of the address or location of a particular one of the records in the base data file. (patents.com)
  • techniques
  • For the users of general libraries this may be all that is needed, but when the same subject-classification techniques are applied to highly specialized collections of nonbook, technically detailed data, the imprecision of such methods of content retrieval becomes apparent. (encyclopedia.com)
  • By the 1970s several different retrieval techniques had been shown to perform well on small text corpora such as the Cranfield collection (several thousand documents). (wikipedia.org)
  • priorities

  • text
  • In his later years, he worked on new ways of information visualization and also genetic algorithms to optimize text queries. (wikipedia.org)
  • The aim of this was to look into the information retrieval community by supplying the infrastructure that was needed for evaluation of text retrieval methodologies on a very large text collection. (wikipedia.org)
  • content
  • The articles bring together a complete story, multimedia content, an article outline, research aids and links to related information. (wikipedia.org)
  • different
  • In contrast, Enfish's patents describe a table structure that allows the information that would normally appear in several different tables to be stored in a single table. (wikipedia.org)
  • Sciences
  • Korfhage then joined the faculty at North Carolina State University (1962-64), Purdue University (1964-70), Southern Methodist University (1970-86) and the University of Pittsburgh School of Information Sciences (1986-98). (wikipedia.org)

  • libraries
  • Modern libraries are increasingly being redefined as places to get unrestricted access to information in many formats and from many sources. (wikipedia.org)
  • community
  • A library is a collection of sources of information and similar resources, made accessible to a defined community for reference or borrowing. (wikipedia.org)
  • analysis
  • Taube defines Coordinate Indexing as, "the analysis of any field of information into a set of terms and the combination of these terms in any order to achieve any desired degree of detail in either indexing or selection. (wikipedia.org)
  • Uniterms "constitute a special set of rules and requirements which makes both the analysis into terms and the combination of the terms in order to specify items of information a remarkably simple and efficient process. (wikipedia.org)
  • access
  • Once the desired records in the base data file have been identified in this manner, they are then selected and displayed, copied, etc., as desired to provide the requisite access or retrieval of information that had previously been stored in the base data file. (patents.com)
  • reduce
  • An intuitive and easy-to-learn programming language and packaged programs called procedures significantly reduce the amount of code needed to deliver information. (sas.com)
  • represent
  • Furthermore, the set of predetermined identifiable characteristics is itself chosen, in one exemplary embodiment, to represent the alphabetic value and relative sequential location of information characters in associated groups of characters such as words contained in the records. (patents.com)
