Abstract
An approach is provided for inducing table of contents (TOC) knowledge in a model-based information retrieval (IR) system. A TOC searcher in a model-based IR system is trained by fine tuning a large language model (LLM) to learn about a plurality of TOC entries specifying structures of documents and how to select from the plurality of TOC entries to respond to a query. The most granular TOC entries for a given document are identified. The given document is marked with leaf node markers which indicate the identified TOC entries. A user query is received and analyzed. By using the leaf node markers and the LLM, a TOC entry included in the identified TOC entries is identified as specifying a portion of the given document that includes an answer to the analyzed user query.
