SurveyGraph: Generating Academic Surveys via Methods-Entity Knowledge Graphs

Read the original on arXiv Computation and Language →

SurveyGraph introduces a framework that uses a Methods‑Entity Knowledge Graph (MEKG) to encode relationships such as follow‑on, competition, and shared‑resource links between research methods. The graph enables core‑paper discovery, hybrid outlining, and evidence‑gated narrative synthesis, outperforming flat lexical baselines in recall and achieving strong citation support and semantic edge validation. The study demonstrates MEKG’s effectiveness through controlled benchmarks, diagnostic tests, and human adjudication, positioning it as an auditable structural layer for survey generation.

SurveyGraph: Generating Academic Surveys via Methods-Entity Knowledge Graphs

SurveyGraph introduces a framework that uses a Methods-Entity Knowledge Graph (MEKG) to generate academic surveys, addressing limitations of flat document retrieval by encoding method-level follow‑on, competition, and shared‑resource relations. The graph enables core‑paper discovery, retrieval, hybrid outlining, and evidence‑gated narrative synthesis, and is evaluated on retrieval, semantic edges, citation grounding, coverage, and generation components. Experiments show MEKG‑anchored fusion balances recall and structural density, graph‑aware retrieval nearly doubles recall over flat baselines, and a semantic evidence gate achieves an AUC of 0.75, with audits indicating strong citation support and relation accuracy.

Entity-Memory Graph Retrieval Improves Evidence Coverage in Long-Conversation Question Answering

Entity-Memory graph retrieval preserves dialogue turns as verbatim memory nodes, links repeated mentions via shared entities, and connects adjacent memories with chronological edges. During retrieval, the system gates through entities, fuses semantics, and performs one‑hop chronological recovery before dense backfill, allowing it to keep neighboring memories that dense cosine ranking might miss. On 1,986 questions from ten LoCoMo conversations, this graph retrieval method increases official evidence recall at top‑k 25 from 79.7468 % to 84.4842 %, with the advantage extending from top‑k 5 to 50, though it does not improve overall final‑answer F1.

Agent Zero Memory: Provenance-Aware Long-Term Memory for LLM Agents

Agent Zero Memory is a provenance‑aware long‑term memory system for large language model agents that distills user interactions into three parallel memory structures: an episodic timeline, an associative entity‑event knowledge graph, and a semantic, citation‑locked hierarchical documentary memory. Retrieval is performed via an intent gate, source router, and concurrent searches across the three systems, producing integrated, cited answers that exclude fabrication and require evidence the reader has opened. The system achieves state‑of‑the‑art performance on LongMemEval (95.60%) and LoCoMo (93.60%) while offering a favorable accuracy‑cost‑latency trade‑off across multiple backbone LLMs.
