Method for gauging public interest in a topic using network analysis of online discussions

摘要

Described is system and method for gauging public interest in a topic using network analysis of online discussions. A message from an online discussion related to a specific topic is received as input. The message is analyzed for information related to the message, and a graph comprised of nodes is generated where each node represents information related to the message, such as user name, location, hyperlinks, and annotations. The graph is updated over time as additional messages from the online discussion are received. Additional nodes are generated and linked with at least one of the existing nodes in the graph to form at least one connected component. A normalized diameter of the largest connected component in the graph is determined, and a level of collective focus in the online discussion related to the topic based on the normalized diameter is output to a user.
