支持图文混合查询的化学文献搜索工具，一键查反应、结构与文本。
Multimodal Search in Chemical Documents and Reactions
- 融合分子图、文本描述和反应数据的多模态检索
- 可从文献中提取图表、表格反应数据并建立跨模态链接
- 适合化学研究者快速定位复杂化学信息
我们提出一种多模态搜索工具，可从科学文献中检索化学反应、分子结构及相关文本。用户可通过分子结构图、文字描述或反应数据组合查询，实现不同化学信息表达形式的关联。索引过程包括化学图谱提取与解析、文本中表格形式的反应数据抽取，以及图文间的跨模态关联。本文描述了系统的架构、核心功能与检索流程，并附有专家评估。该演示重点展示搜索工作流与技术组件。
原文摘要 · Abstract (English)
We present a multimodal search tool that facilitates retrieval of chemical reactions, molecular structures, and associated text from scientific literature. Queries may combine molecular diagrams, textual descriptions, and reaction data, allowing users to connect different representations of chemical information. To support this, the indexing process includes chemical diagram extraction and parsing, extraction of reaction data from text in tabular form, and cross-modal linking of diagrams and their mentions in text. We describe the system's architecture, key functionalities, and retrieval process, along with expert assessments of the system. This demo highlights the workflow and technical components of the search system.
