| 摘 要： | 目的/意义] 随着人们对检索文档之间关联关系的理解越来越多样化和细粒度化，检索文档内信息单元间关联关系的构建显得越来越重要。本研究旨在以学术文档内信息单元间关联关系为基础，构建文档的细粒度聚合与关联机制。方法/过程] 本研究从跨体裁聚合单元知识体系所蕴涵的各类关联关系出发，从信息组在的角度阐述支持情景和语义关联的细粒度聚合理论框架、知识组织系统构建和聚合单元元数据标注等关键问题，并提出聚合机制。结果/结论] 研究认为构建蕴含聚合单元语义关系、学科领域语义关系、任务和文本关系的本体，采用可反应聚合单元层级与关联关系的聚合单元元数据，是细粒度聚合机制发挥效用的关键。

| Abstract: | Purpose/Significance] The relationship among the information units is important to study.The relationship among information units in the internet environment has been explored diversely and granularly.The purpose of this paper was to explore how to fully utilize the associations among aggregation units across genres and associations between aggregation units and users.Method/Process] This study started from the association among the information units within genres of academic documents;then it proposed the mechanism of information aggregation and discusses key issues including construction of knowledge organization system and labeling of metadata for information units.Result/Conclusion] This paper pointed out that the construction of ontology for fine-grained aggregation and the metadata for aggregation units were essential in the process of information organization. |
