1. A computer implemented system for an application agnostic user search engine for searching social networks across a plurality of computer-based social networks and external data bases sources that can be used to support applications with different optimization criteria, the system comprising:
a computer data store containing:
a plurality of external data base sources containing social network user data for a social network user;user profiles extracted from multiple social networks and from the external data base sources for the social network user; a computer server coupled to the computer data store and programmed to:
using a collection framework for collecting social network user data from the social networks selected from the group consisting of user messages, user connections, user interactions, user biographies, user profile information, a user social graph, and user content actions and user content reactions;using a data processing component, aggregating the collected social network user data,deriving properties selected from the group consisting of topical, temporal and contextual properties from the social network user data;identifying the social network users and using the user data to create normalized user documents, the normalized user documents having demographic information, system scores, and topic interests;indexing the normalized user documents into a searchable database;identifying features in the normalized user data and using the results as training data for machine learning models;building machine learning models using historical user actions from the normalized user documents;updating the machine learning models and storing the updated machine learning models in the computer data store; andusing an application objective function and the machine learning model, outputting a list of user documents matching a query criteria. |
