Abstract: Dynamic, knowledge-based networking systems, apparatuses, articles of manufacture, and methods are disclosed that may employ a database that is accessible via a communications network. The database stores information related to one or more users of the communications network. The networking system further includes an information engine. A query is received by the information engine from a mobile device via the communications network. The information engine is configured to determine a context of the query, compare the query and/or context with the information in the database to generate a contextual result, identify one or more users associated with the contextual result, and generate a directory of identifiers representing the identified one or more users.
