Semantic Scholar. Semantic Scholar is a research tool for scientific literature powered by artificial intelligence. It is developed at the Allen Institute for AI and was publicly released in November 2015. [ 2] Semantic Scholar uses modern techniques in natural language processing to support the research process, for example by providing ...
A primary source in science is one where the authors directly participated in the research. They filled the test tubes, analyzed the data, or designed the particle accelerator, or at least supervised those who did. Many, but not all, journal articles are primary sources—particularly original research articles.
PubMed. PubMed is a free database including primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintains the database as part of the Entrez system of information retrieval.
The main academic full-text databases are open archives or link-resolution services, although others operate under different models such as mirroring or hybrid publishers. Such services typically provide access to full text and full-text search, but also metadata about items for which no full text is available.
For a source to be added to this list, editors generally expect two or more significant discussions about the source's reliability in the past, or an uninterrupted request for comment on the source's reliability that took place on the reliable sources noticeboard. For a discussion to be considered significant, most editors expect no fewer than ...
Many other measures have been proposed, beyond simple citation counts, to better quantify an individual scholar's citation impact. [20] The best-known measures include the h-index [21] and the g-index. [22] Each measure has advantages and disadvantages, [23] spanning from bias to discipline-dependence and limitations of the citation data source ...
Historians carry out original research, often using primary sources. Historians often have a PhD or advanced academic training in historiography, but may have an advanced degree in a related social science field or a domain specific field; other scholars and reliable sources will typically use the descriptive label historian to refer to an historian.
Semantic integration is the process of interrelating information from diverse sources, for example calendars and to do lists, email archives, presence information (physical, psychological, and social), documents of all sorts, contacts (including social graphs ), search results, and advertising and marketing relevance derived from them.
