minimal-ir

Minimalistic information retrieval system based on the vector space modeling. The system recommends documents included in corpus to users in profiles based on the interests of each user.

User1#movies#politics
User2#politics#soccer
User3#politics

For example, it will recommend documents about movies and politics to the first user. You can add entries to this file to include more user profiles. However, for the moment only 4 topics are supported: movies, politics, soccer and books (the dictionary only includes these terms).

Run the program with the following command:

python profileir.py

You can also run the tests:

python -m unittest discover

This should be the output:
