What will I learn?

This Information Retrieval Course provides a quick, practical pathway to developing high-quality search capabilities. You'll delve into foundational keyword techniques, TF-IDF, and BM25, before progressing to semantic retrieval using embeddings, ANN, and efficient indexing. Gain skills in analysing datasets, modelling user intent, creating test queries, labelling relevance, assessing precision@5, and implementing real enhancements through monitoring, A/B testing, and introductory learning-to-rank concepts.
