Glossary additions integrated






INTRODUCTION

  • The Canadian Search Standards Working Group (CSSWG) has complied this glossary of terms to develop a standard lexicon for literature searching.
  • A search standard or code of practice, and a list of standard definitions facilitate coherent conversations among professionals.
  • This glossary contains more than 150+ terminologies used in the literature related to searching for health information.
  • For each definition, a relevant source or sources have been cited.

ADJACENCY OPERATOR - See proximity operator

AUTOMATIC TERM MAPPING

  • Definition"...The process used to find a controlled vocabulary term. For example in PubMed it is used to match unqualified terms that are entered into the query box. If a match is found in any translation table, the mapping stops. When subject or journal matches are found, the query and individual terms are also searched in All Fields. If no match is found in any tables, terms are searched in All Fields and ANDed together."

METADATA

  • DefinitionMetadata is structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use, or manage an information resource. Metadata is often called data about data or information about information. The term metadata is used differently in different communities. In the library environment, metadata is commonly used for any formal scheme of resource description, applying to any type of object, digital or non-digital. Traditional library cataloging is a form of metadata; MARC 21 and the rule sets used with it, such as AACR2, are metadata standards. Other metadata schemes have been developed to describe various types of textual and non-textual objects including published books, electronic documents, archival finding aids, art objects, educational and training materials, and scientific datasets.

QUERY

  • Definition: A request submitted as input in a search of an online catalog or bibliographic database to retrieve records or documents relevant to the user's information need(s).

The query is an approximation of the information need that provides the impetus for the search.

RELEVANCE / RELEVANCY

  • Definition: The extent to which information retrieved in a search of a library collection or other resource, such as an online catalog or bibliographic database, is judged by the user to be applicable to ("about") the subject of the query.

Measures of the effectiveness of information retrieval, such as precision and recall, depend on the relevance of search results. Compare with pertinence.

SPECIFY

STEMMING AND LEMMATIZATION

  • DefinitionFor grammatical reasons, documents are going to use different forms of a word, such as organizeorganizes, and organizing. Additionally, there are families of derivationally related words with similar meanings, such as democracydemocratic, and democratization. In many situations, it seems as if it would be useful for a search for one of these words to return documents that contain another word in the set.
    The goal of both stemming and lemmatization is to reduce inflectional forms and sometimes derivationally related forms of a word to a common base form.

Statistical methods (meta-analysis) may or may not be used to analyze and summarize the results of the included studies. A systematic review differs from a traditional literature review in that a literature review only describes and appraises previous work, and but does not specify the methods by which the reviewed studies were identified, selected, or evaluated.
