Abstract: A system comprises: a filter actor execution system configured to execute filter actors to identify content items relevant to a topic of interest, each filter actor configured to examine the content items for satisfaction of filter criteria and to identify a subset of content items that satisfy the filter criteria; a deep review actor execution system configured to execute deep review actors to conduct deep review processing of the subset of content items, each deep review actor configured to perform semantic analysis on the subset of content items to generate deep review actor data; a correlation actor execution system configured to execute correlation actors to identify links within the subset of content items; a complex event actor execution system configured to execute complex event actors to identify patterns within the subset of content items; and an actor management system configured to instantiate the hierarchy of actors.
