Subject Re: Automatically extracted Mahout FAQs
Date Thu, 09 Jun 2011 20:18:07 GMT
Hello everyone,

a few weeks ago I had introduced some research we are currently doing. 
It’s about considering a large corpus of mailing lists, clustering the 
threads using LDA and using the models to select the most relevant Q/A’s 
from each cluster to form topic-focused FAQs.

We’ve now created a tool for reviewing the generated FAQs. Within 
approx. 10 minutes, you can select and reformulate good question/answer 
pairs found by our system. Eventually, you will be able to download the 
FAQ in HTML or XML. We will also use your selected questions to further 
evaluate and improve our system.

You can review the FAQ generated from the cluster mainly relating to 
Mahout at The selections remain past the 
session, so the mailing list can cooperate on the review.

We are eagerly looking forward receiving your feedback on the review 
process and system.

Yours sincerely,

Stefan and Martin
University of Darmstadt, Germany
