knowledge base

knowledge base A collection of knowledge, usually relevant to a particular application domain, that has been formalized in an appropriate scheme to support reasoning processes. Rule-based formalisms are often used but there are other methods of knowledge representation. Knowledge bases are different from databases in that (a) they not only store data but facilitate modification, revision, and other forms of internal manipulation of the knowledge, (b) they are also able to handle knowledge that is incomplete (see completeness), inconsistent, and uncertain, and (c) they may use imperative as well as declarative forms of knowledge.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
