WebWeaver - Ali Tongyi open source new dual-intelligence body framework

What is WebWeaver

WebWeaver is a new dual-intelligence body framework introduced by Alibaba's Tongyi team, under the umbrella ofTongyi DeepResearchThe WebWeaver family, mainly used in open and deep research, can simulate the human research process, and is divided into two intelligences, planning and writing, which are responsible for exploring and generating outlines, while writing is responsible for content synthesis. The core innovation of WebWeaver is dynamic outline optimization, which uses the research outline as a "living document", cycling between search and outline refinement to dynamically evolve the direction of the research as new discoveries are made. WebWeaver is based on a hierarchical synthesis methodology that builds reports section by section, ensuring that they are coherent, accurate, and deeply source-dependent.

WebWeaver Features

• Efficient Information Retrieval and Integration: Quickly find information from a large number of web pages that is relevant to the research topic, integrated into a logical structure.
• Dynamic Outline Optimization: Consider the research outline as a "living document", cycling between searches and outline refinement, so that the research direction dynamically evolves with new discoveries and avoids a solidification of the research direction.
• Layered Synthesis Report: Reports are constructed based on a hierarchical synthesis approach, with section-by-section content generation to ensure that reports are coherent, accurate and deeply source-dependent.
• Enhancement of small model capabilities: Lower the bar for high-quality research by equipping small models with expert-level research capabilities through the WebWeaver-3k dataset.

WebWeaver's Core Advantages

• Dynamic Adaptation: Dynamically adjusting the research direction and outline based on newly discovered information, avoiding path dependency in the research process, and making the research more flexible and in-depth.
• Efficient information processing: Rapidly extract valuable content from massive information through intelligent search and filtering mechanisms, significantly improving research efficiency.
• Coherence and accuracy: Constructing reports based on a hierarchical synthesis methodology to ensure consistency and accuracy of report content and enhance the quality of research.
• Lowering the research threshold: To make it easy for more people to conduct high-quality research by empowering small models with expert research capabilities, supported by datasets and frameworks.
