This paper describes two services of the Torii portal dedicated to the High Energy Physics research community, and developed within the context of the TIPS European project. These services both relate to the reuse of evaluations performed by humans on scientific publications. The first one, called QCT (Quality Control Tools) aims at collecting human detailed evaluations of documents in order to enrich the traditional topical indexing of documents with quality-related information. The second one, called SF (Social Filtering) integrates a push functionality as a alternate and complementary tool to traditional pull services such as Information Retrieval; documents are pushed to users with respect to the evaluations they have made in the past, and as compared to other users' evaluations.
