InfoSeeker: A Scalable Hierarchical Parallel Agent Framework for Web Information Seeking
In a groundbreaking development in the field of information retrieval, researchers have introduced InfoSeeker, a novel framework designed to enhance the efficiency and effectiveness of web information seeking. The work, documented in arXiv:2604.02971v1, highlights the limitations of current agentic search systems, particularly their struggles with wide-scale information synthesis.
Background
Recent advancements in agentic search systems have focused heavily on deep, multi-step reasoning. While these systems have shown considerable promise, they frequently fail to adequately address the complexities involved in aggregating vast amounts of heterogeneous evidence from multiple sources. This oversight has resulted in several key challenges:
- Context Saturation: As agents gather more information, they often struggle to maintain context, leading to reduced effectiveness.
- Cascading Error Propagation: Errors in early stages of data processing can amplify, resulting in inaccurate outcomes.
- High End-to-End Latency: Slow processing speeds hinder the overall responsiveness of search systems, making them less practical for real-time applications.
The InfoSeeker Framework
To tackle these challenges, InfoSeeker employs a hierarchical framework based on the principle of near-decomposability. The architecture is comprised of:
- Host: The central orchestrator that manages the overall workflow and resource allocation.
- Managers: Multiple units that handle the aggregation and reflection mechanisms, ensuring strict context isolation.
- Workers: Parallel agents that execute tasks, significantly enhancing processing speed.
This multi-layered approach allows the framework to effectively isolate contexts at the Manager layer, preventing saturation and limiting error propagation. The parallel processing capabilities of the Worker layer further accelerate task execution, addressing the issue of latency that plagues many existing systems.
Performance Evaluation
The InfoSeeker framework has been rigorously evaluated against two complementary benchmarks, producing impressive results:
- Achieved a speed-up of 3-5 times in overall task execution.
- Demonstrated an 8.4% success rate on the WideSearch-en benchmark.
- Achieved 52.9% accuracy on the BrowseComp-zh benchmark.
Availability
The research team has made the code for InfoSeeker publicly available, allowing others in the field to explore and build upon this innovative framework. The code can be accessed at https://github.com/agent-on-the-fly/InfoSeeker.
Conclusion
InfoSeeker represents a significant advancement in the capability of agentic search systems to handle large-scale information synthesis efficiently. By addressing the limitations of existing frameworks through its unique hierarchical architecture, InfoSeeker paves the way for more effective web information seeking in data-intensive environments.
