EMERGING TOPIC DISCOVERY

摘要

This document discusses, among other things, a method for discovering a new topic. The method includes identifying a first topic within a first document and comparing the first topic to a first set of topics. The method then determines whether an emergence time for the first topic can be identified. The first topic is recognized as a new topic based on the comparison between the first set of topics and the emergence time for the first topic. For example, when the first topic does not exist within the first set of topics and the emergence time for the first topic can be identified, the first topic is recognized as a new topic.
