Information Retrieval System
The idea of the project is to build information retrieval systems, evaluate and compare their performance levels in terms of retrieval effectiveness. The dataset provided to us contains 3204 raw documents. We used CACM test collection as our textual corpus,
64 unprocessed queries, Relevance judgments and a stop-list.
- Developed search engines with BM25, Lucene, tf.idf, query likelihood as retrieval models.
- Performed Query Expansion techniques on BM25 and tf.idf using Pseudo-Relevance Feedback approach.
- Performed Stopping, Stemming and indexed the stemmed version of the corpus that was provided to us and performed query by query analysis on all the models.
- A total of 11 distinct runs were generated to assess the performance of these search engines.
Following parameters were used to evaluate the efficiency and effectiveness of the different retrieval models:-
- Mean Average Precision
- Mean Reciprocal Rank
- p@K, K = 5 and 20
- Precision and Recall
