to the difficulty of quickly accessing the content of interest in a long video lecture. In this work, we present “video indexing” and “keyword search” that facilitate access to video content and enhances user experience. Video indexing divides a video lecture into segments indicating
This paper presents a novel keyword selection-based spoken document-indexing framework that selects the best match keyword from query candidates using spoken term detection (STD) for spoken document retrieval. Our method comprises creating a keyword set including keywords that are likely to be in a spoken document
on WCN. The proposed method exploits the information provided by WCN in order to enhance relevant keyword extraction. In addition, querying the index for a given keyword has worst case complexity O(log n), as compared to usual keyword spotting algorithms which run in O(n). Experiments show promising results in keyword
based on keyword indexing, there are many records in their result lists that are irrelevant to the user's information needs. It is shown that for retrieving more relevant and precise results, the following two points should be concerned: First of all, the query (either it is generated by a human or an intelligent agent
Information retrieval becomes a very complex process for search engines on the Web, this is due to, first, the staggering growth speed of the number of web site and, in the other hand, the search algorithms by keywords (terms) used currently are not suitable to better exploit this huge information quantity. These
