摘要： The subject disclosure is directed towards using a satisfaction model's prediction as to whether a user was satisfied or dissatisfied in satisfying a search goal to help estimate the relevance of a URL/document that was returned and clicked by the user. The clickthrough data for a search goal session is processed by either a utility model or a despair model based on whether the satisfaction model indicated that the search goal session ended with the user satisfied or dissatisfied, respectively. The utility model distributes a utility value to each clicked URL, while the despair model distributes a despair value to each clicked URL. The utility value and despair value of each query-URL pair may be used as corresponding feature data for learning a search ranker.

摘要： A system that captures both whiteboard content and audio signals of a meeting using a video camera and records or transmits them in real-time. The Real-Time Whiteboard Capture captures pen strokes on whiteboards in real time using an off-the-shelf video camera. Unlike many existing tools, the RTWCS does not instrument the pens or the whiteboard. It analyzes the sequence of captured video images in real time, classifies the pixels into whiteboard background, pen strokes and foreground objects (e.g., people in front of the whiteboard), and extracts newly written pen strokes. This allows the RTWCS to transmit whiteboard contents using very low bandwidth to remote meeting participants. Combined with other teleconferencing tools such as voice conference and application sharing, the RTWCS becomes a powerful tool to share ideas during online meetings.

摘要： The subject disclosure is directed towards evaluating search engine implementation performance using a task-based assessment metric. Logged user activities associated with the search engine implementation are processed into sessions and atomic events corresponding to the user activities within the sessions. The atomic events corresponding to the user activities are classified into tasks based on similarity of the queries within the user activities. After applying the task-based assessment metric to task information associated with the search engine implementation, an evaluation mechanism determines indicia of search engine implementation performance in terms of user behavior.

摘要： Cryopreserved boar spermatozoa is much less fertile than that of other species, which could be due to damage to sperm membrane lipids during the cryopreservation process. Incorporation of selected lipids improves the survival of boar spermatozoa following cryopreservation. Liposomes were made from lipids extracted from head plasma membrane (HPM) of boar spematozoa or from selected lipids (SL) which contained specific phospholipids. At a fixed lipid concentration, fusion efficiency with spermatozoa as measured by flow cytometry and R18 dequenching was affected by lipid type, sperm concentration and incubation time. SL and HPM improved sperm viability (SYBR-14 and propidium iodide) and motility during cooling to 5C., with SL±egg yolk better than or equal to HPM (P
