irplus: Open-Source Information Retrieval Toolkit
An open-source IR toolkit for research and experimentation, providing tools for indexing, search, classification, and evaluation.
What is Irplus?
irplus is an open-source information retrieval toolkit designed for research and experimentation. It provides a set of tools and libraries for common information retrieval tasks:
- Indexing - tools to parse documents, tokenize text, filter stopwords, apply stemming, and create inverted indexes
- Search - APIs for performing queries against indexes and ranking results
- Classification - implementations of algorithms like naïve Bayes and SVM for text classification tasks
- Evaluation - utilities for measuring precision, recall, nDCG, and other common IR evaluation metrics
Some key benefits of irplus include:
- Modular design - components can be used together or independently
- Optimization - critical components use C++ for speed
- Scale - built to handle large document collections and vocabularies
- Extensibility - newstopic models, ranking functions, etc. can be added
- Free & open source - BSD licensed code
irplus would be useful for researchers and students interested in testing IR algorithms or using information retrieval in applications. The code is actively maintained on GitHub.
