Abstract: Methods and apparatus related to determining an inquiry to provide to a user based on deficient information related to a plan of the user. Deficient information may be determined based on an insufficient association between a desired information item of the plan and a set of information items that are determined from one or more sources associated with the user. In some implementations, the user may provide, responsive to the inquiry, additional information related to the deficient information and a suggestion may be provided to the user based on the additional information.

Abstract: Methods and apparatus for providing travel-related information for a location to a user based on activity indications of the user that are related to the location. The location may be determined based on a set of one or more related activity indications and a travel-related score may be determined for the location that is indicative of likelihood that the user has interest in travelling to the location. The user may be provided the travel-related information for the location based on the travel-related score.

Abstract: Methods, apparatus and computer-readable media (transitory and non-transitory) are disclosed for determining one or more additional task features for a task of a user. In some implementations, the additional task features may be determined based on additional information from one or more sources that are distinct from the source(s) from which the task is identified or determined. The additional task features may be determined based on the additional information and based on user information that is associated with the user. For example, the additional information may define a superset of information and the additional task features may be a subset of the defined superset. The additional task features may be utilized to generate a task notification related to the task, and the task notification may be provided for presentation to the user.

Abstract: Methods, apparatus and computer-readable media (transitory and non-transitory) are disclosed for identifying a good or service of potential interest to the user and a context in which the good or service would be consumed, determining, based on historical data, a statistic about resources expended by other users to consume goods or services of a same class as the good or service of potential interest to the user in contexts that correspond to the predicted context, and providing an indication of the statistic. In some implementations, the good or service of potential interest to the user may be predicted, e.g., based on one or more signals associated with the user.

Abstract: In one aspect, an automated endorsement prompt systems includes an endorsement prompt module comprising an endorsement signal module for retrieving an endorsement signal from an endorsement server; a search result module for retrieving search results from a search engine; a web history module for retrieving a web history for a user; and combiner logic for providing search results and an endorsement prompt. The combiner logic generates the endorsement prompt from the endorsement signal and the web history. A method for automatically generating endorsement prompts including the steps of: receiving a query from a user; obtaining additional information signals; obtaining a search result using the query; determining whether prompt behavior exists using the additional information; generating a prompt for an endorsement if the prompt behavior exists; and providing the search result and the prompt for presentation.

Abstract: Methods and apparatus are disclosed for determining supervised training data, such as travel-related supervised training data, for training a machine learning system. In some implementations, supervised training data may be determined that includes input features based on information items of users and desired output features based on one or more physical locations visited by users.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for a transport protocol independent communications library. In one aspect, a method includes receiving a communication request from a client device and processed according to a selected transport protocol, generating a response to the communication request, the response including data responsive to the communication request and one or more feature values specifying one or more communication features for the communication request, each communication feature being independent of the selected transport protocol, and providing the response to the communication request according to the selected transport protocol.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving a search query, receiving a set of inferred actions, the set of inferred actions including one or more inferred actions that are based on the search query and being identified based on data provided in one or more data sources, providing an electronic document including instructions that, when executed by a computing device, cause the computing device to display a search results page including search results and content associated with inferred actions of the set of actions, and transmitting the electronic document to a computing device associated with a user that submitted the search query.

Abstract: Methods and apparatus for providing travel-related information for a location to a user based on activity indications of the user that are related to the location. The location may be determined based on a set of one or more related activity indications and a travel-related score may be determined for the location that is indicative of likelihood that the user has interest in travelling to the location. The user may be provided the travel-related information for the location based on the travel-related score.

Abstract: Methods, apparatus and computer-readable media (transitory and non-transitory) are disclosed for receiving audio information based on sensing of one or more audible sounds; identifying one or more voice profiles, wherein each of the voice profiles is associated with an individual and indicates one or more voice characteristics of the associated individual; determining at least a given voice profile of the one or more voice profiles matches the audio information; determining co-presence of the user with at least the individual associated with the given voice profile based on determining the given voice profile matches the audio information; identifying an action that includes a trigger based on co-presence of the user and the individual associated with the given voice profile; and invoking the action based on the determined co-presence of the user with at least the individual associated with the given voice profile.
