Lucene for Sentiment Analysis
Hello, I was interested to learn about using Lucene for text analytics work such as for Sentiment Analysis. Has anyone done work along these lines? if so, could you share your approach, experiences, accuracy levels obtained etc.
Thanks,
AS

Hi
I remember doing it once a long time ago (Lucene 1.9) but could not go
anywhere since term vectors and such were not easily accessible then.
However, if text analytics is what you are after, perhaps you already
know about LingPipe. I used it for named entity extraction (enhanced
with some TF-IDF statistical information from Lucene Index) and it
worked well.
Maybe, you can do the same for sentiment analysis i.e. use LingPipe
capabilities but enhance it with the corpus statistics that the Lucene
index provides - and which are more powerful now.
HTH,
Srikant

We've been working on Sentiment Analysis. We use GATE and Wordnet for the
lexical / semantic analysis and J Free Charts for the visualization. The
domain is reviews on retail banking and in general our accuracy is around
75% and recall around 25%
We tried out lingpipe as well which also gave good results.
