Information science

The Information Science examines information and knowledge. Relevant for the understanding of information science, the importance of information as a dynamic process (active: inform; passive: to be informed ) and of knowledge as something static, which is fixed in documents, as personal knowledge in the minds of people, or elsewhere.

" Information Science examines the Evaluate / Select, developing, deploying / recycling, Search, Transfer and find relevant (primarily digitally on ) knowledge, through information and communication processes "

The information is referred to as relevant, in the query ( Query) through the hit in question is objectively satisfied. Whether, however, that " pertinent " for the seeker of subjective utility of the results, is the relevance measure is irrelevant.

Gernot Wersig described information science with an emphasis on the interdisciplinary approach as a triad of knowledge, human and Information Technology: Information Science is therefore

" [ ... ] The science of knowledge use under the terms of the new information and communication technologies at all levels - individual, organizational, cultural, societal "

The information science comes to a bridge by their relatively "neutral " viewpoint of knowledge transfer. Information science is both systematically and thematically and methodologically closely associated with journalism, media and communication science, cognitive psychology, computational linguistics, computer science ( science of processing information ) and corresponding more specific forms of economic or legal computer science. From a scientific perspective information is always the user is at the center when looking at the interface between people and systems.

Evaluation

  • Information retrieval / information retrieval. Classical retrieval approaches are the vector space model and the probabilistic model. In Web information retrieval linktopologische models (such as PageRank, or the Kleinberg algorithm) are added.
  • Boolean systems or natural language systems
  • Classical databases ( such as dialogue, Questel - Orbit patent search tool, GBI Genios or LexisNexis ) and search engines ( like Google or Yahoo)
  • Information Science is a theoretical, empirical and applied science and its practical methods fundamental discipline of Internet economy and intra-company information science and thus the foundation of the information society.

Subareas and research priorities

Employment environment

Information Scientists find both in the Internet industry, in the media and in the corporate knowledge management their professional activity.

The Information Science deals with informational processes and their support apart by information systems. It's like media or communication studies, closely related to a number of neighboring disciplines, also include the technical subjects such as computer science, such as humanities or social science disciplines. This also explains the different localization in the sciences at the various universities. So you can find the information science at some universities in the Philosophical Faculty at the language and literature, (eg at the University of Regensburg ), in Linguistics / Applied Linguistics (eg at the University of Hildesheim ), at other universities in the Department of Library Science (eg at the Stuttgart Media University Stuttgart). At the Heinrich -Heine- University Dusseldorf Information Science is strongly connected to the computer science and computational linguistics. The Fachhochschule Potsdam offers in the stand-alone department " Information Science " a wide range of practical studies at. Is correspondingly broad and the field of work of an information scientist. Employment in traditional institutions such as libraries, archives and documentation centers are also common, such as the career in an industrial enterprise, for example, with the emphasis on dialogue design of user systems, management consulting firms in the provision of information or knowledge management.

Documentation science, archival science, library science, information management and media sector are sub-areas of information science.

Neighboring disciplines are:

  • Mass Communication
  • Communication Science
  • Media Studies
  • Webwissenschaft

The practical application of information science techniques will be implemented not only in the BID area ( library, information and documentation science ), but also in the mass media, implemented the areas of consulting and advisory services, finance and cultural goods sector, for example in museums.

Learning and Teaching

Information science is taught at some German universities and colleges as a separate subject; However, the specific expression of the teaching content differs depending on the university. Similar content can be found partly in adjacent courses such as the archive, library and documentation science and journalism and communication science.
