摘要:
Systems and methods for automatically inserting advertisements into source video content playback streams are described. In one aspect, the systems and methods communicate a source video content playback stream to a video player to present source video to a user. During playback of the source video, and in response to receipt of a request from the user to navigate portions of the source video (e.g., a user command to fast forward the source video, rewind the source video, or other action), the systems and methods dynamically define a video advertisement clip insertion point (e.g., and insertion point based on a current playback position). The systems and methods then insert a contextually relevant and/or targeted video advertisement clip into the playback stream for presentation to the user.

摘要:
A video search re-ranking via multi-graph propagation technique employing multimodal fusion in video search is presented. It employs not only textual and visual features, but also semantic and conceptual similarity between video shots to rank or re-rank the search results received in response to a text-based search query. In one embodiment, the technique employs an object-sensitive approach to query analysis to improve the baseline result of text-based video search. The technique then employs a graph-based approach to text-based search result ranking or re-ranking. To better exploit the underlying relationship between video shots, the re-ranking scheme simultaneously leverages textual relevancy, semantic concept relevancy, and low-level-feature-based visual similarity. The technique constructs a set of graphs with the video shots as vertices, and the conceptual and visual similarity between video shots as hyperlinks. A modified topic-sensitive PageRank algorithm is then applied to these graphs to determine the overall relevancy ranking.

A method and system for identifying informative links of a web site for use in crawling the web site is provided. A forum crawler analyzes sample web pages of a web forum to identify informative links and then crawls the web forum by following links determined to be informative and not following other links. The forum crawler system determines whether links are informative based on whether they are part of the overall structure of the web site or are used to select sequential information that has been split onto multiple web pages.
摘要:
Described is a technology by which forum web pages are processed into clusters for classification purposes, including by determining repetitive regions between pages and associating pages that have similar repetitive regions into a common cluster. Patterns corresponding to the regions are determined, and a feature set based at least in part on those patterns (e.g., pattern frequency) is extracted from the page. The feature set of a page is compared against the feature set of another page to determine similarity therewith, e.g., via a feature space distance computation that is evaluated against a threshold distance.
