Exploring a Multidimensional Representation of Documents and Queries (extended version) [article]

Benjamin Piwowarski and Ingo Frommholz and Mounia Lalmas and Keith van Rijsbergen
2010 arXiv   pre-print
In this paper we experimentally investigate the effect of these parameters, showing that the proposed representation of documents and queries as multidimensional objects can compete with standard approaches  ...  However, it may be more beneficial to consider documents and/or queries as multidimensional objects.  ...  Finally, two lines of research explored, respectively, a subspace representation of documents [7] and of a user's IN [7] .  ...
