Abstract: An online system trains a constraint prediction machine-learning model using an action-based loss function. The action-based loss function computes a weighted sum of (1) an accuracy of the constraint prediction model in predicting whether a user's interaction complies with a set of constraints and (2) an action score representing a number of actions taken by users to determine whether the user's action complies with the set of constraints. The online system may apply this trained constraint prediction model to future interaction data received from third-party systems to predict whether user interactions with those third-party systems comply with the set of constraints.

Abstract: A method for displaying and dynamically updating a user interface displaying a listing of air tickets available for purchase on a flight includes receiving, by a computing device, a plurality of search results including at least one fare listing for an air ticket for a seat on a flight and unstructured data including at least one rule associated with the search result. The computing device assigns an initial quality rating for each of the plurality of search results. The computing device receives, for each of the plurality of search results, structured data identifying at least one amenity and analyzes the received structured and unstructured data. The computing device assigns a modified quality rating to at least one of the plurality of search results and displays, to a second computing device, an enumeration of each of the plurality of search results categorized based on the quality ratings.

Abstract: A method of guiding a user's web navigation through the recommendation of online content in the form of a navigation recommendation includes a server and a browser. The browser receives identification associated with a user in a navigation network and transmits the login information to the server. The browser additionally transmits information about the user's browsing activity to the server. The server receives browsing activities from many browsers having associated users and stores information indicating an association between the users and their respective interactions. The server additionally receives social networking information for the users and stores information indicating an association between the user and their respective social connections. Based on an input received from the browser associated with the user in the navigation network, the server determines a navigation recommendation for the user based on the stored information and transmits the navigation recommendation to the browser.

Abstract: Disclosed are methods and systems for downloading map data. A database of layers of map data is maintained. The map data may be representative of at least one map image of a geographic area. Each layer may provide progressively more detailed display information. Map data is downloaded to a client computer, and the may data may be sufficient to allow a user to navigate within a geographic area without requiring new map data to be downloaded.

Abstract: Various methods and systems are disclosed for downloading geographical map data representative of at least one map image of a geographic area. In response to a request for map data, a subset of geographical map data is provided. The subset of geographical map data may be arranged into one or more minimal-sorted groups. The minimal-sorted groups may be used to restore the map data represented by the subset.

Abstract: A method for doing business, wherein a web server maintains a commercial subscriber database including a plurality of records each containing data relating to commercial subscribers including at least name, address and category, and imposes a periodic subscription fee on at least some of the commercial subscribers. On receiving from a client machine connected thereto a request to download data relating to at least one specified category of commercial subscriber, it extracts from the commercial subscriber database respective records and sends to the client machine for display thereby, allows receipt of an update from one or more commercial subscribers in respect of substitute or supplementary data to that contained in the respective database record of the commercial subscribers, and updates the commercial subscriber database as required.
