Assessment of Conversation Co-mentions as a Resource for Software Module Recommendation

Tue, 06/02/2009 - 10:50 — Daniel Zhou

This paper is submitted to ACM Recommender System Conference'09, co-authored with my advisor Prof. Paul Resnick.

ABSTRACT

Conversation double pivots recommend target items related to a source item, based on co-mentions of source and target items in online forums. We deployed several variants on the drupal.org site that supports the Drupal open source community, and assessed them through clickthrough rates and subjective assessments of the relevance of the recommendations. Overall, clickthrough rates increased by a factor of 15 from the beginning to the end of the tuning process. A similarity metric based on correlation of mentions rather than mere co-occurrence reduced the problem of over-recommending the most popular modules, but additional corrections for recency and uniqueness of mentions were not helpful. Detection of more module mentions in conversations dramatically improved the quality of recommendations, even though the detection algorithm then had more false positives. Recommendations based on conversation co-mention were more effective than those based on co-installation, because co-installation data only led to recommendations of complementary modules and not substitutes.

Attached is the full-paper.

In terms of the similarity of the marks, Christian louboutin Shoes has not shown that the
use of the word Christian louboutin Shoes, when heard or viewed in the totality of a radio
ad, brochure, or counter display, was likely to cause confusion. For many reasons, the use
of the word Christian louboutin in the context of these two promotions would have seemed
utterly unexceptional.
