Abstract: Methods, systems, and apparatus, including computer programs encoded on a non-transitory computer storage medium, for providing reverse auctions for goods and services in real-time. In one aspect, a method includes storing profile information associated with a plurality of information sources, each source associated with a category. A request for information from a user including information associated with a good or service sought is analyzed to identify information sources as responsive to the request based on a comparison of the good or service sought and each information source's associated category. Responses are solicited from the identified information sources. In response, a set of responses from at least a subset of the identified information sources is received, which are then ranked based on a comparison of the particular response to the request for information, and at least a subset of which are presented to the user based on the ranking.

Abstract: Methods, systems, and computer program products are provided for generating and posting messages to social networks based on voice input. One example method includes receiving an audio signal that corresponds to spoken content, generating one or more representations of the spoken content, and causing the one or more representations of the spoken content to be posted to a social network.
