Our new term extraction service analyzes text and an optional query, returning a list of the key concepts from the text. You can use the service for a variety of different purposes. For example, Y!Q uses it to determine key concepts within the search context and then uses those terms for augmenting a user's search query.
TagSEA aims to be a robust, extendable framework with exemplary tools used for tagging and waypointing source code, resources, or whatever you would like within Eclipse.
