Academic project, written for course "Information retrieval" (Oct 2014 - Feb 2015)
Together with partner we:
-Came up with a project idea (search system, that indexes posts of some news groups in VK.com)
-Implemented and presented it
My part was backend development:
-Building inverse index for up to 500k documents
-Performing lemmatization with MyStem library
-Building a syntax for querying, with automatic expansion of every query keyword to it's synonyms
-Parsing VK groups with API to gather posts
This repository contains only pieces of code written by me, that are relevant to this project.
