    摘要： 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.

    摘要： 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.

    摘要： 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.
