Highlighting, Keywords and Summarizing

["Schuh, Stefan" <St...@coi.de>]

Hi,

I'm looking for tools (code) which provides information for:

- Highlighting (of search results)
- extracting of keywords (in different languages)
- and summarizing of text (giving a short description of a long text)

Has anyone an idea if there is some code or solutions (based on lucene)
for using?

Regards

Stefan

Lucene includes a highlighter in its contrib area.  You can see an 
example of it here: http://www.lucenebook.com/search?query=highlighter

Highlighter is currently in a build-it-yourself state in Lucene's 
Subversion repository, however it will be released in binary official 
form with Lucene 1.9 in the near future.  You can get the binary of it 
from the Lucene in Action source code download.

Please elaborate on what you're after here.

Classifier4j has a text summarizer:
