Python framework for fast Vector Space Modelling
Project description
Gensim is a Python framework designed to help make the conversion of natural language texts to their underlying semantic representation as simple and natural as possible.
Gensim contains fast implementations of algorithms for unsupervised learning from raw, unstructured digital texts, such as Latent Semantic Analysis, Latent Dirichlet Allocation or Random Projections. These algorithms discover hidden (latent) corpus structure. Once found, documents can be succinctly expressed in terms of this structure, queried for semantic similarity and so on.
If the previous paragraphs left you confused, you can first read more about the Vector Space Model and unsupervised document analysis on Wikipedia.
Installation
This software depends on NumPy and Scipy, two Python packages for scientific computing. You must have them installed prior to installing gensim. You can get them from <http://www.scipy.org/Download>.
The simple way to install gensim is:
sudo easy_install gensim
Or, if you have instead downloaded and unzipped the source tar.gz package, you’ll need to run:
python setup.py test sudo python setup.py install
For alternative modes of installation (without root priviledges, development installation), see the documentation.
This version has been tested under Python 2.5 and 2.6, but should run on any 2.5 <= Python < 3.0.
Documentation
Manual for the gensim package is available in HTML. It contains a walk-through of all the features and a complete reference section. It is also included in the source distribution package.
Gensim is open source software, and has been released under the GNU LPGL license. Copyright (c) 2010 Radim Rehurek
