Abstract: Architecture that includes a multimodal graph modeling and computation system employed in a search framework. The framework utilizes entities to diversify and explore the results page. The multimodal graph modeling paradigm can include web modeling by way of a click graph, a web graph, a social graph, a geospatial graph, and an entity graph, for example. These graphs are then joined based on common properties such as links, clicks, and document entities. Computation can then be performed over the joined graphs to generate a related entity list and a related page list. These lists are then processed by a recommendation engine to provide recommendations to the user.

Abstract: Methods, computer systems, and computer-readable storage media for generating and presenting multi-domain recommendations to a user viewing a Web page are provided. A topic-of-interest is identified on the Web page being viewed by the user. The topic-of-interest is mapped to an entity ID in a multi-domain recommendation data structure. The multi-domain recommendation data structure is used to identify entities, uniform resource locators, and search queries mapped to the entity ID. Multi-domain recommendations are generated using the entities, uniform resource locators, and search queries; the multi-domain recommendations are presented on the Web page being viewed by the user.

Abstract: Functionality is described for forming a summary representation of a video item to help a user decide whether to obtain a full version of the video item. The functionality operates by: (a) receiving a video item; (b) dividing the video item into a plurality of segments; (c) extracting at least one key frame from each of the plurality of segments to form a plurality of key frames; and (d) organizing the video segments into one or more groups corresponding to one or more respective scenes based on the plurality of key frames, to thereby form the representation of the video item. The functionality can be used to communicate search results to a user, to provide a sample of the video item in a message, etc.

Abstract: The present invention relates, in part, to methods of treatment, prevention, and inhibition of viral disorders. In one aspect, the present invention relates to inhibition of the M2 proton channel of influenza viruses (e.g. influenza A virus) and other similar viroporins (e.g., VP24 of Ebola and Marburg viruses; and NS3 protein of Bluetongue). The present invention further relates, inter alia, to compounds which have been shown to possess antiviral activity, in particular, inhibiting the M2 proton channel of influenza viruses.

Abstract: A pattern tree is constructed based on a plurality of key-value pairs representing portions of a data set. In some implementations, the pattern tree may be used for learning one or more rules for interacting with a source of the data set.

Abstract: Web crawling polices are generated based on user web browsing statistics. User browsing statistics are aggregated at the granularity of resource identifier patterns (such as URL patterns) that denote groups of resources within a particular domain or website that share syntax at a certain level of granularity. The web crawl policies rank the resource identifier patterns according to their associated aggregated user browsing statistics. A crawl ordering defined by the web crawl polices is used to download and discover new resources within a domain or website.

Abstract: The present disclosure provides compounds having affinity for the M2 proton channel, useful for the treatment of viral infections such as influenza, which are of the Formula (I): wherein R1, R2, and Y are as defined herein. Methods of preparing the compounds, pharmaceutical compositions containing the compounds, and methods of using the compounds in the treatment of viral infections such as influenza are also provided.

Abstract: Techniques for determining user information needs and selecting data based on user information needs are described herein. The present disclosure describes extracting topics of interests to users from multiple sources including search log data and social network website, and assigns a budget to each topic to stipulate the quota of data to be selected for each topic. The present disclosure also describes calculating similarities between gathered data and the topics, and selecting top related data with each topic subject to limit of the budget. A search engine may use the techniques described here to select data for its index.

Abstract: A control circuit, a control method, and a power supply device are provided. The control circuit includes an obtaining sub-circuit, adapted to obtain a voltage signal from a reverse surge current when the reverse surge current appears on a primary side of a switch power circuit of a synchronous rectification circuit; a maintaining sub-circuit, adapted to continuously output a first control signal in a preset first time period when the voltage signal is greater than a preset first voltage threshold; and a control sub-circuit, adapted to control and switch off switch tubes of the secondary side of the switch power circuit of the synchronous rectification circuit according to the first control signal. Thus, a reverse current surge of the switch power circuit of the synchronous rectification circuit can be effectively suppressed, and the safety of a switch power supply of the synchronous rectification circuit can be effectively protected.

Abstract: Techniques for index building are described. Clickcounts of respective training URLs may indicate a number of times that corresponding training URLs were clicked in search engine results. A machine learning algorithm implemented on a computer computes a trained model that is then stored. The clickcounts and respective URLs are passed to the machine learning algorithm to train the model to predict probabilities based on feature vectors of URLs. An index of web pages is built for a set of URLs that identify the web pages. Feature vectors for the URLs are computed. Probabilities of the web pages of the URLs being searched in the future by users may be computed by processing the feature vectors with the trained model. The probabilities may be used to determine which of the URLs to include in the index.
