Annotating graphs to allow quick loading and analysis of very large graphs

An information processing system for analyzing very large graphs, comprising:

• an analyzer for identifying analysis information relevant to an analysis domain;
• a handler for determining said analysis information for each of a plurality of nodes of a very large graph representing at least one aspect of said analysis domain;
• an association for associating said analysis information with each said node;
• an aggregator for aggregating said node annotations to form a data stream, whereby said data stream preserves said analysis information in a way which allows scalable post-processing of said data stream;
• and
• a process for producing said data stream for subsequent analysis

A computer readable medium including computer instructions for regulating communication of information in a data structure between components of a computer program, the computer instructions including instructions for:

• identifying analysis information relevant to an analysis domain;
• determining said analysis information for each of a plurality of nodes of a very large graph representing at least one aspect of said analysis domain;
• associating said analysis information with each said node to form node annotations;
• combing said node annotations and said plurality of nodes to form a data stream, whereby said data stream preserves said analysis information in a way which allows scalable post-processing of said data stream;
• and
• producing said data stream for subsequent analysis
