Improving new user recommendations with rule-based induction on cold user data
TLDR
In this paper, classical new user cold start techniques are improved by exploiting the cold user data, i.e. the user data that is readily available (e.g. age, occupation, location), in order to automatically associate the new user with a better first profile. Expand

Multi-facet Document Representation and Retrieval
TLDR
We participated through a simple IR model based on three hypotheses: 1) the amount of overlap between a document and a query, 2) the descriptive power of an indexing element, and 3) the discriminative power. Expand
