Towards Finding Valuable Topics [chapter]

Zhen Wen, Ching-Yung Lin
2010 Proceedings of the 2010 SIAM International Conference on Data Mining  
For the second question, we identify and evaluate a set of significant factors including both content and social network factors.  ...  In particular, the social network factors are better in filtering out low-value topics, while content factors are more effective in selecting a few top high-value topics.  ...  preliminary subjective topic evaluation: (4.11) u(N ) = N j=1 rating j T j=1 rating j where rating j is the human rating of the j-th topic.  ...

A Connection-Centric Survey of Recommender Systems Research [article]

Saverio Perugini, Marcos Andre Goncalves, Edward A. Fox
2003 arXiv   pre-print
While research in recommender systems grew out of information retrieval and filtering, the topic has steadily advanced into a legitimate and challenging research area of its own.  ...  Recommendations, however, are not delivered within a vacuum, but rather cast within an informal community of users and social context.  ...  In addition, we thank him for feedback regarding initial drafts of this survey. Furthermore, discussion summaries and feedback from those in CS6604 improved the organization of this paper.  ...
