Grounding Agent Memory in Contextual Intent (2026.findings-acl)
Copied to clipboard
| Challenge: | Large language models are deployed in long-horizon tasks that require agents to track interleaved goals, resolve references to prior information, and coordinate actions over extended trajectories. |
| Approach: | They propose an agentic memory system that indexes each trajectory step with a structured retrieval cue, contextual intent, and retrieves history by matching the current step’s intent. |
| Outcome: | The proposed system outperforms the strongest benchmark by 35.6%, with the largest gains as trajectory length increases. |
Scientific Paper Retrieval with LLM-Guided Semantic-Based Ranking (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Recent studies also use large language models (LLMs) for query understanding, but these methods lack grounding in corpus-specific knowledge and may generate unreliable or unfaithful content. |
| Approach: | They propose a paper retrieval framework that combines large language models (LLMs) with a concept-based semantic index to capture scientific concepts. |
| Outcome: | The proposed framework improves the performance of various base retrievers, surpasses strong existing LLM-based baselines, and remains highly efficient. |
