Summarizer

The summarizer used by Portal Search is a facility for summarizing Web pages and other types of documents. It returns a summary for documents which have a certain narrative quality, that is, they are coherent, and above a certain, 'telegraphic', length. The summary consists of the three most salient sentences of the original document. The summary is shown with the document in the list of search results.

The summarizer produces summaries for all languages that are supported by the portal. For some languages the summarizer has access to a stemmer program. It uses stems as the base forms for words, as opposed to the lemma forms used by summarizers which have dictionaries. Summaries for these languages can have better quality. For a list of these languages refer to Language support for Portal Search.
