Adaptive Hybrid Information Retrieval for Wikipedia Search Using Lexical, Fuzzy, Phonetic and Semantic Retrieval

An adaptive hybrid information retrieval system for Wikipedia search that combines lexical, fuzzy, phonetic and semantic retrieval.

An adaptive hybrid information retrieval system for Wikipedia search that combines lexical, fuzzy, phonetic and semantic retrieval. This reference project walks through the whole job, from the problem and the design to the build and the evaluation, so that a developer can study how it works, run it and extend it.

It suits learners who want to work with language models and text or speech: preparing text data, using or fine-tuning a model, evaluating it and building an interface around it.

The main parts are text or speech data preparation, model training, fine-tuning or prompting, evaluation with task-appropriate metrics, and a chat or web interface to use it. The reference build uses LangChain, FAISS, Python, Hugging Face Transformers, and spaCy, with a clear project structure, setup instructions and sample data so that it can be run and extended.
