Entity Tracking: Corpus Map Enhances Autonomous Search

New research introduces a corpus map that helps LLM agents iteratively link evidence across multiple documents for complex queries.
A new research paper titled **“Follow the Entities: A Corpus Map for Agentic Search”** proposes a structural overhaul for large‑scale document retrieval by LLM‑driven agents. The authors—Soyeong Jeong, Sujay Kumar Jauhar, Sung Ju Hwang and Andrew Joohun Nam—introduce **CorpusMap**, an offline‑built navigation layer that anchors searches on repeatedly occurring entities. By parsing cross‑document references to the same entity, CorpusMap aggregates information and links every mention, turning a flat corpus into a web of entity pages.
In experiments spanning seven language models and three benchmark datasets, CorpusMap consistently lifted evidence discovery and answer quality while cutting average token consumption. It also outperformed four competing navigation approaches, suggesting that entities serve as reliable anchors for traversing massive text collections. The authors argue that current agentic search pipelines waste effort by repeatedly rediscovering the same connections during each query, a problem CorpusMap solves at ingest time.
The development matters because agentic LLMs—such as the work‑focused “Dots” product we covered on 30 September—still grapple with token‑heavy, flat corpora that can miss critical evidence spread across documents. By reducing token load and improving answer fidelity, CorpusMap could lower operational costs and broaden the feasibility of enterprise‑grade, multi‑document question answering.
What to watch next includes integration of CorpusMap into commercial agentic platforms, open‑source releases of the accompanying code (hosted on GitHub under the “agentic‑search” topic), and further benchmark results on real‑world knowledge bases. If the approach scales, it may become a standard preprocessing step for any LLM agent tasked with navigating large, heterogeneous document stores.
