Introduction - FAST Taxonomy

The FAST Taxonomy Explorer contains Categorization, based on advanced Linguistic technologies that let you control the flow of information into your organization and order, access, and retrieve that data; as well as information created within your organization.

The Categorizer classifies documents and organizes information into a hierarchical or a flat set of categories.Categorization is the process of concisely defining the information within a particular doc-ument; in other words, the major topic or subject of the document. In the context of text-
based document searches, categorization is an automated process that classifies numerous text documents, placing them into a taxonomy. A taxonomy is an organized classification structure that facilitates information retrieval.The categorization process inserts category tags into the documents prior to indexing.

When the documents in an index have been categorized, end users can restrict a query to a specific category in that index. Categorizing documents increases the likelihood that your end users will obtain the meaningful results they seek for two reasons:

1. Metadata: Documents are organized and stored by category, according to
their metadata tags.

2. Filter: Queries can be filtered using the categories that you created as
part of your taxonomy.

You can also choose to categorize the end-user documents from among several languages.FAST have Taxonomy Explorer to create & test a catagory.
