跨媒体检索

基于Ontology的跨媒体检索技术

Ontology-based Cross-media Retrieval Technique

第四章提出了一个基于PersonalizedPageRank和交叉关联图的跨媒体检索的方法。

In chapter four , we introduce another cross-media retrieval algorithm , which is based on Personalized PageRank and cross-reference graph .

第三章提出了一个基于相似度融合的跨媒体检索的方法，通过SimFusion对不同媒体对象间的相似度进行融合，再通过MDS得到媒体对象在语义空间中的坐标，由此实现跨媒体检索。

We first fuse the similarity between different media objects via Sim-Fusion algorithm , and then by doing MDS , we can obtain the media objects ' coordinates in semantic space . Using these coordinates , we can realize cross-media retrieval .

通过改进PersonalizedPageRank算法并将其应用到交叉关联图上，仿照对网页按重要性排序来对媒体对象按相似性排序，取得了令人满意的跨媒体检索的效果。

We improve the Personalized PageRank and apply it to the cross-reference graph , so that we can rank the media objects according to their similarity with the query , just as PageRank do according to webpages ' importance . The result of this algorithm is satisfying .

基于时空相关性的跨媒体检索模型研究与应用

Research and Application of Cross-Media Retrieval Model Based on Temporal-Spatial Correlation

在跨媒体检索这一领域做出了初步的尝试。

This is our first attempt in the area of cross-media retrieval .

基于多模态融合和时空上下文语义的跨媒体检索模型的研究

Research of cross-media information retrieval model based on multimodal fusion and temporal-spatial context semantic

提出一种支持海量跨媒体检索的集成索引结构。

This paper proposes a novel integrated indexing structure for the large-scale cross-media retrieval .

基于综合推理的多媒体语义挖掘和跨媒体检索

Cross-Media Retrieval Based on Synthesis Reasoning Model

使用多模态的信息对电视节目进行结构化，并利用跨媒体检索的技术获取和节目相关的网络内容和生成超链接。

Multimodal information is used to structurize the TV program and to produce the hyperlinks to Web content .

而在跨媒体检索中，一个首先遇到的难题就是不同模态的媒体对象间相似度的计算问题。

However , one of the first problems in cross-media retrieval is the similarity measurement of different types of media objects .

阐述了跨媒体检索的概念和相关技术；讨论了跨媒体检索的概念及其和单一媒体检索的比较；分析了跨媒体检索中常采用的技术和发展现状。

We elaborate on the concept and related techniques of cross-media information retrieval , which is compared with the information retrieval for the single kind of media . The common technical solutions cross-media information retrieval in are also discussed . 4 .
