- Semantic search is a process used to improve online searching by using data from semantic networks to disambiguate queries and web text in order to generate more relevant results. Hildebrand et al. provide an overview that lists semantic search systems and identifies other uses of semantics in the search process. Guha et al. distinguish two major forms of search: Navigational and Research. In navigational search, the user is using the search engine as a navigation tool to navigate to a particular intended document. Semantic Search is not applicable to navigational searches. In Research Search, the user provides the search engine with a phrase which is intended to denote an object about which the user is trying to gather/research information. There is no particular document which the user knows about that s/he is trying to get to. Rather, the user is trying to locate a number of documents which together will give him/her the information s/he is trying to find. Semantic Search lends itself well here. Rather than use ranking algorithms such as Google's PageRank to predict relevancy, Semantic Search uses semantics, or the science of meaning in language to produce highly relevant search results. In most cases, the goal is to deliver the information queried by a user rather than have a user sort through a list of loosely related keyword results. Other authors primarily regard semantic search as a set of techniques for retrieving knowledge from richly structured data sources like ontologies as found on the Semantic Web . Such technologies enable the formal articulation of domain knowledge at a high level of expressiveness and could enable the user to specify his intent in more detail at query time.
- Eine Semantische Suchmaschine ist eine Suchmaschine, die natürliche Sprache als Eingabe akzeptiert und versucht die Semantik einer Frage zu erfassen. Anschließend sucht sie in ihrem Datenbestand nach passenden Antworten. Idealerweise besteht die Antwort dabei aus einzelnen Aussagen statt ganzen Dokumenten, wie bei an Stichworten orientierten Suchmaschinen üblich.
