Extracting semantic representations from word co-occurrence statistics: A computational study
Computational Methods for Intelligent Information Access
Currently, most approaches to retrieving textual materials from scientific databases depend on a lexical match between words in users' requests and those in or assigned to documents in a database. Because of the tremendous diversity in the words people use to describe the same document, lexical methods are necessarily incomplete and imprecise. Using the singular value decomposition (SVD), one can take advantage of the implicit higher-order structure in the association of terms with documents by determining the SVD of large sparse term by document matrices. Terms and documents represented by 200-300 of the largest singular vectors are then matched against user queries. We call this retrieval method Latent Semantic Indexing (LSI) because the subspace represents important associative relationships between terms and documents that are not evident in individual documents. LSI is a completely automatic yet intelligent indexing method, widely applicable, and a promising way to..

From the twilight of cultural memory: the 'Bumah' in the mosques of central Oman
We give a short introduction to the theory of twisted Alexander polynomials
of a 3--manifold associated to a representation of its fundamental group. We
summarize their formal properties and we explain their relationship to twisted
Reidemeister torsion. We then give a survey of the many applications of twisted
invariants to the study of topological problems. We conclude with a short
summary of the theory of higher order Alexander polynomials.Comment: 42 pages, final version of the survey paper to be published by the
proceedings of the conference `The Mathematics of Knots: Theory and
Application' in Heidelberg in December 2008. In the final version we updated
references and fixed a few typo
