| == 08/20/2012: TopSig – Signature Files Revisited (Shlomo Geva)==
| |
| '''Speaker:''' Shlomo Geva, Queensland University of Technology, Australia<br/>
| |
| '''Time:''' Monday August 20, 11:00 AM<br/>
| |
| '''Venue:''' AVW 3120<br/>
| |
| | |
| '''Abstract:''' Performance comparisons between File Signatures and Inverted
| |
| Files for text retrieval have previously shown several
| |
| significant shortcomings of file signatures relative to inverted
| |
| files. The inverted file approach underpins most state-of-theart
| |
| search engine algorithms, such as Language and Probabilistic
| |
| models. It has been widely accepted that traditional
| |
| file signatures are inferior alternatives to inverted files. This
| |
| paper describes TopSig, a modern approach to the construction
| |
| of file signatures - many advances in semantic hashing and
| |
| dimensionality reduction have been made in recent times,
| |
| but these were not so far linked to general purpose, signature
| |
| file based, search engines. This paper introduces a different
| |
| signature file approach that builds upon and extends
| |
| these recent advances. We are able to demonstrate significant
| |
| improvements in the performance of signature file based
| |
| indexing and retrieval, performance that is comparable to
| |
| that of state of the art inverted file based systems, including
| |
| Language models and BM25. These findings suggest that
| |
| file signatures offer a viable alternative to inverted files in
| |
| suitable settings and position the file signature model in
| |
| the class of Vector Space retrieval models.
| |
| TopSig is an open-source search engine from QUT and it can be discussed too if there is an interest.
