Semantic search tools seek to improve the accuracy of web searching by considering context (or meaning) of terms as they occur in desirable web documents. Instead of Google’s PageRank to predict relevancy, semantic search tools use the science of meaning in language to produce relevant results for users. The goal on semantic search is to deliver information in context rather than have to sort through lists of loosely related keyword results. Some authors regard semantic search tools as a set of techniques to retrieve knowledge from richly structured data sources which enable technologies to articulate domain knowledge at a sophisticated level. Semantic tools on the web are likely to rely on metadata to describe documents and bring them together in information retrieval. This language will help to describe and retrieve documents much like what we encounter in medical databases. Metadata is defined as ‘data about data’ and the major standard in the field is Dublin Core. For more background, see the Semantic Media wiki.
