Information retrieval (IR) in computing and information science is the task of identifying and retrieving information system resources that are relevant to an information need. The information need can be specified in the form of a search query. In the case of document retrieval, queries can be based on full-text or other content-based indexing. Information retrieval is the science of searching for information in a document, searching for documents themselves, and also searching for the metadata that describes data, and for databases of texts, images or sounds.
Information science is an academic field which is primarily concerned with analysis, collection, classification, manipulation, storage, retrieval, movement, dissemination, and protection of information. Practitioners within and outside the field study the application and the usage of knowledge in organizations in addition to the interaction between people, organizations, and any existing information systems with the aim of creating, replacing, improving, or understanding the information systems.
A digital object identifier (DOI) is a persistent identifier or handle used to uniquely identify various objects, standardized by the International Organization for Standardization (ISO). DOIs are an implementation of the Handle System; they also fit within the URI system. They are widely used to identify academic, professional, and government information, such as journal articles, research reports, data sets, and official publications.
The Intergovernmental Oceanographic Commission of UNESCO (IOC/UNESCO) was established by resolution 2.31 adopted by the General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO). It first met in Paris at UNESCO Headquarters from 19 to 27 October 1961. Initially, 40 States became members of the commission. The IOC assists governments to address their individual and collective ocean and coastal management needs, through the sharing of knowledge, information and technology as well as through the co-ordination of programs and building capacity in ocean and coastal research, observations and services.
The National Science Library (NSL), formerly known as the Canada Institute for Scientific and Technical Information or CISTI, began in 1917 as the library of the National Research Council of Canada (NRC). NRC is the Government of Canada's premier research and technology organization (RTO), working with clients and partners to provide innovation support, strategic research, scientific and technical services. The library took on the role of national science library unofficially in 1957 and became the official National Science Library in 1966.
Chemical Abstracts Service (CAS) is a division of the American Chemical Society. It is a source of chemical information and is located in Columbus, Ohio, United States.
A federated identity in information technology is the means of linking a person's electronic identity and attributes, stored across multiple distinct identity management systems.
The Office of Scientific and Technical Information (OSTI) is a component of the Office of Science within the U.S. Department of Energy (DOE). The Energy Policy Act PL 109–58, Section 982, called out the responsibility of OSTI: "The Secretary, through the Office of Scientific and Technical Information, shall maintain with the Department publicly available collections of scientific and technical information resulting from research, development, demonstration, and commercial applications activities supported by the Department."
Federated search retrieves information from a variety of sources via a search application built on top of one or more search engines. A user makes a single query request which is distributed to the search engines, databases or other query engines participating in the federation. The federated search then aggregates the results that are received from the search engines for presentation to the user. Federated search can be used to integrate disparate information resources within a single large organization ("enterprise") or for the entire web.
Slightly over half of the homepages of the most visited websites on the World Wide Web are in English, with varying amounts of information available in many other languages. Other top languages are Chinese, Spanish, Russian, Persian, French, German and Japanese.
A search engine is a software system that provides hyperlinks to web pages and other relevant information on the Web in response to a user's query. The user inputs a query within a web browser or a mobile app, and the search results are often a list of hyperlinks, accompanied by textual summaries and images. Users also have the option of limiting the search to a specific type of results, such as images, videos, or news.
A bibliographic database is a database of bibliographic records. This is an organised online collection of references to published written works like journal and newspaper articles, conference proceedings, reports, government and legal publications, patents and books. In contrast to library catalogue entries, a majority of the records in bibliographic databases describe articles and conference papers rather than complete monographs, and they generally contain very rich subject descriptions in the form of keywords, subject classification terms, or abstracts.
A concept search is an automated information retrieval method that is used to search electronically stored unstructured text for information that is conceptually similar to the information provided in a search query. In other words, the ideas expressed in the information retrieved in response to a concept search query are relevant to the ideas contained in the text of the query.
Scitopia.org is a free federated, vertical search portal that enables users to explore the collective content of 21 science and technology societies – the research most cited in scholarly work and patents – from a single search box on the open web. It aggregates the entire electronic libraries of its founders – societies in major science and technology disciplines. More than three million documents, including peer-reviewed journal content, spanning hundreds of years of scientific and technological discovery, and conference proceedings, are searched through this dedicated gateway.
Science.gov is a web portal and specialized search engine. Using federated search technology, Science.gov serves as a gateway to United States government scientific and technical information and research. Currently in its fifth generation, Science.gov provides a search of over 60 databases from 14 federal science agencies and 200 million pages of science information with just one query, and is a gateway to 2,200+ scientific websites.
AGRIS is a global public domain database with more than 12 million structured bibliographical records on agricultural science and technology. It became operational in 1975 and the database was maintained by Coherence in Information for Agricultural Research for Development, and its content is provided by more than 150 participating institutions from 65 countries. The AGRIS Search system, allows scientists, researchers and students to perform sophisticated searches using keywords from the AGROVOC thesaurus, specific journal titles or names of countries, institutions, and authors.
The OpenSIGLE repository provides open access to the bibliographic records of the former SIGLE database. The creation of the OpenSIGLE archive was decided by some major European STI centres, members of the former European network EAGLE for the collection and dissemination of grey literature. OpenSIGLE was developed by the French INIST-CNRS, with assistance from the German FIZ Karlsruhe and the Dutch Grey Literature Network Service (GreyNet). OpenSIGLE is hosted on an INIST-CNRS server at Nancy. Part of the open Access movement, OpenSIGLE is referenced by the international Directory of Open Access Repositories.
Science Accelerator was a web-based gateway to science information including research results from the U.S. Department of Energy (DOE). The information was provided as a free public service by the DOE Office of Scientific and Technical Information (OSTI), within the Office of Science. It used federated search technology to search DOE-generated and DOE-related science information databases and collections. Federated search technology allowed the user to search multiple data sources with a single query in real time. It provided simultaneous access to "deep web" scientific databases, which were typically not searchable by commercial search engines.
The International Council for Scientific and Technical Information (ICSTI) aims to promote cooperation among all those engaged in the scientific communication process by engaging national scientific unions and their respective scientific communities. It is a broad-based, international, not-for-profit membership organization based in Paris, France.
PATENTSCOPE is a global patent database and search system developed and maintained by the World Intellectual Property Organization. It provides free and open access to a vast collection of international patent documents, including patent applications, granted patents, and related technical information.
