cranfield-collection

Implementation of a Vector Space Retrieval Model using TF-IDF and cosine similarity on the Cranfield document corpus

Performs tokenization, stemming, lemmatization, index creation, index compression and ranked retrieval of Cranfield documents

Implementation of Salton and Buckley paper using 2 methods TF-IDF & Best Weighted Probabilistic

An Information Retrieval System with 3 models and 3 datasets from the ir_datasets library .

An advanced form of the previously implemented search Engine which acts as a information retrieval system over the cranfield collection of the 1400 documents and also makes use of the stemmer algorithm. Other things are pretty much the same as the previously implemented SearchEngine project.

Cranfield collection in TREC XML format.

Python-based Information Retrieval system leveraging the BIM probabilistic model. Features include handling free-form text queries, relevance & pseudo-relevance feedback. Performance is rigorously evaluated using metrics like precision/recall, mean average precision, and R-precision. Utilizes the standard Cranfield dataset from aerodynamics.
