Dr-DCI: Scaling Direct Corpus Interaction via Dynamic Workspace Expansion
Quick Answer
DR-DCI enhances Direct Corpus Interaction by dynamically expanding local workspaces for efficient document retrieval and operations, achieving 71.2% accuracy on Browsecomp-Plus and outperforming BM25 in large corpora.
Quick Take
Its design allows for scalable exploration while maintaining precision, with accuracy improving to 73.3% through context resets.
Key Points
- DR-DCI achieves 71.2% accuracy, improving by up to 8.3 points over raw DCI.
- Performance remains stable from 100K to 10M documents, unlike raw DCI.
- Ablation analysis highlights the importance of ranked previews and inter-document DCI.
- Context reset feature boosts accuracy to 73.3% on Browsecomp-Plus.
- DR-DCI scores 63.0 on Wiki-18 QA across six benchmarks.

arXiv:2606. 14885v1 Announce Type: new Abstract: Agentic search over large corpora relies on retriever-mediated interfaces (e. g. , BM25 or ColBERT) for scalable candidate discovery. While effective at ranking relevant documents, these interfaces expose evidence only as ranked results or bounded document views, limiting agents' ability to reorganize material and verify constraints across documents.
Direct Corpus Interaction (DCI) addresses this limitation by exposing shell-executable corpus operations for flexible search, filtering, comparison, and verification. However, full-corpus terminal commands become slow and unstable as the corpus grows, degrading performance and efficiency. …

HOBA (Hierarchical On-policy Bidding Agents) is a novel hierarchical reinforcement learning framework that enhances online advertising bidding systems by improving adaptability and reducing hyperparameter tuning costs. It utilizes a for hyperparameter inference, a SARSA agent for expert model selection, and a dynamic expert pool for bid execution, achieving a +3.6% increase in target cost during large-scale deployment and outperforming state-of-the-art baselines on AuctionNet.
