    摘要: Blogs (and other information sources) are recommended to a user based history of user's online activities. The system: (1) processes the user's web history, (2) identifies blog posts (and web pages) that link to pages read by the user, (3) generates multiple relevance scores for each identified post/page, and (4) produces multiple rankings of the corresponding source blogs (and web sites) by aggregating individual relevance scores (or combinations of relevance scores), according to users' preferences. The system allows the discovery of information sources that are likely to be interesting to the user and allows sources lost in the “long tail” to be seamlessly discovered.

    摘要: A system and method for identifying key frames of a presentation video that include stationary informational content. A sequence of frames is obtained from a presentation video and differences of pixel values between consecutive frames of the sequence of frames are computed. Sets of consecutive frames that are stationary are identified, wherein consecutive frames that are stationary have a proportion of changed pixel values below a first predetermined threshold, and wherein pixel values are deemed to be changed when the difference between the pixel values for corresponding pixels in consecutive frames exceeds a second predetermined threshold. Next, a set of key frames that include stationary informational content is retained. The set of key frames that include stationary informational content is then displayed for user interaction.

    摘要: A method for navigating instructional video presentations is disclosed. The method includes determining a pause mode of a video presentation, and playing the video presentation on a display device. The video presentation has one or more predetermined pause positions. The method also includes, while playing the video presentation, determining that the video presentation has reached one of the one or more pause positions. The method further includes, in accordance with a determination that the video presentation is in a first pause mode, pausing the video presentation at the one of the one or more pause positions and maintaining a display of a paused frame of the video presentation, and, in accordance with a determination that the video presentation is in a second pause mode distinct from the first pause mode, continuing to play the video presentation through the one of the one or more pause positions.

    摘要: An interactive system provides for increasing retrieval performance of images depicting text by allowing users to provide relevance feedback on words contained in the images. The system includes a user interface through which the user queries the system with query terms for images contained in the system. Word image suggestions are displayed to the user through the user interface, where each word image suggestion contains the same or slightly variant text as recognized from the word image by the system than the particular query terms. Word image suggestions can be included in the system by the user to increase system recall of images for the one or more query terms and can be excluded from the system by the user to increase precision of image retrieval results for particular query terms.
