  • Patent number: 9699019
    Abstract: One or more techniques and/or systems are provided for displaying related content associated with browsing a website. For example, a user may access a website to view content provided by the website. As opposed to the user manually searching for interesting content through trial and error, related content that may be interesting to the user may be identified and surfaced to the user. For example, a user profile specifying user interests of the user may be used to identify related content assigned topics corresponding to the user interests (e.g., content provided by the website or other web source). In this way, the related content may be displayed to the user through a content recommendation reader interface. In an example, the content recommendation reader interface may be provided by a web browser so that related content may be identified and/or provided to users of any website from any device.

  • Patent number: 9495453
    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.

  • Patent number: 8682811
    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.
