Whoosh was created and is maintained by MattChaput. It was originally created for use in Side Effects Software's 3D animation software Houdini. Side Effects Software Inc. graciously agreed to open-source the code. Some of Whoosh's features include: * Pythonic API. * Pure-Python. No compilation or binary packages needed, no mysterious crashes. * Fielded indexing and search. * Fast indexing and retrieval -- much faster than any other pure-Python solution. * Pluggable scoring algorithm (including BM25F), text analysis, storage, posting format, etc. * Powerful query language parsed by pyparsing. * Pure Python spell-checker (as far as I know, the only one).     http://whoosh.ca/     tags: python bm25 search whoosh tallstreet's Whoosh-AppEngine at master - GitHub     Whoosh is a fast, pure-Python indexing and search library. Programmers can use it to easily add search functionality to their applications and websites. Because Whoosh is pure Python, you don't have to compile or install a binary support library and/or make Python work with a JVM, yet Whoosh is still very fast at indexing and searching. Every part of how Whoosh works can be extended or replaced to meet your needs exactly.     http://github.com/tallstreet/Whoosh-AppEngine     tags: gae whoosh search appengine Bollysite Blog » Blog Archive » Python coded GoogleMini SA...     http://blog.bollysite.com/2010/02/08/python-coded-googlemini...     tags: gae ir search sayt Web Exploration and Search Technology Lab     http://cis.poly.edu/westlab/     tags: search invertedindex compression simple9 simple16 p4delta pfordelta www2008 Introduction to Information Retrieval     This is the companion website for the following book.

It can be either used for free indexing or for indexing with a controlled vocabulary.     http://www.nzdl.org/Kea/     tags: ir nlp search kea A Measure of Deviations from Poisson     Low frequency words tend to be rich in content, and vice versa. But not all equally frequent words are equally mean!ngful. We will use inverse document frequency (IDF), a quantity borrowed from Information Retrieval, to distinguish words like somewhat and boycott. Both somewhat and boycott appeared approximately 1000 times in a corpus of 1989 Associated Press articles, but boycott is a better keyword because its IDF is farther from what would be expected by chance (Poisson).     http://www.aclweb.org/anthology-new/W/W95/W95-0110.pdf     tags: ir tfidf search filetype_pdf media_document Welcome to New Idea Engineering, Inc.     http://ideaeng.com/     tags: search precipitate - Google Code     recipitate lets you search for and launch your cloud data from within Spotlight or Google Desktop for Mac.
