This paper provides an overview of the experiments we carried out at the TREC 2011 Session Track. We propose two different approaches to tackle the task introduced this year. The first one relies on a biologically inspired adaptive model for information filtering to build a user profile of multiple topics of interests throughout the session. The learnt(More)
A simulation model of the growth of the plant root system is described. Firstly, the numbers and lengths of the laterals derived from a single axis are obtained from specified rates of elongation and branching. Secondly, the vertical distribution of filament lengt his obtained, after specifying the rate of initiation of axes at the crown of the plant and(More)
Today, searchers exploring the World Wide Web have come to expect enhanced search interfaces – query completion and related searches have become standard. Here we propose a Formal Concept Analysis lattice as an underlying domain model to provide a source of query refinements. The initial lattice is constructed using NLP. User clicks on documents, seen as(More)
