中文摘要: 本项目以网络多媒体应用的迅速兴起与网络话题对现实社会的深刻影响为研究背景,以融合网络数据的跨媒体特性与用户意图为切入点,探索有效的跨媒体话题检测与分析方法,揭示网络热点话题的传播与演化规律。拟从以下方面展开工作:1)针对单一模态数据造成的信息缺失问题,利用多模态数据之间的语义一致性与互补性,探索跨媒体中多模态数据间的有效关联与聚类算法;2)结合网络多源数据的跨媒体特性,探寻高效的多模态数据融合算法和大数据量处理技术,并充分利用用户意图信息,提出有效的网络热点话题检测与分析方法;3)针对单一模态信息表达能力不足的问题,拟以跨媒体全浸方式,结合话题演化的时序关系,对热点话题进行有效的结构化呈现,揭示话题的发生与发展规律;4)根据网络话题传播过程中的强弱趋势分析,检测话题发展中具有关键性作用的重要节点事件,发掘话题传播与发展过程中各个事件之间的相互影响关系。

英文摘要: The background of the project are the rapid rise of the multimedia applications on the web and the great impact of the web topics.This project starts from integrating the characteristic of the cross media data and the user intention, explores the effective method for topic detection and analysis, and reveals the dissemination and evolution of the hot topics. It mainly contains the following four parts: (1) According to information lose problem incured by single modality data, we propose effective data association and clustering algorithm based on the intrinsic semantic consistency between the different modality data.(2) By combining the cross modality characteristc of the internet data and exploring effective multimodality fusion method and large data processing approach, we propose an effective topic detection and analysis method by integrating multimodality data and user intention.(3)Overcome the insufficient representation problem of the single modality data, structuralized exibit the topic by intergrating cross media data, and reveal the propagation of the topic. (4)Detect the key event from the topics according to the topic trend analysis, and reveal the interaction between the events when the topic spreading.
