pyIR: Collection of Information Retrieval algorithms

A collection of algorithms for querying a set of documents and returning the ones most relevant to the query.

The algorithms that have been implemented are:

• Vector Space Model
• Best Match 25
• Unigram Language Model using Jelinek Mercer Smoothing

Installation

If you want to be sure you're getting the newest version, you can install it directly from github with

pip install git+ssh://git@github.com/hrwx/pyIR.git

TREC

The algorithms were implemented primarily to run evaluations using the TREC Cranfield collection. The TREC evaluation can be run from the evaluate.py file.
