Abstract
Systems and methods are disclosed for news events detection and visualization. In accordance with one implementation, a method is provided for news events detection and visualization. The method includes, for example, obtaining a document, obtaining from the document a plurality of tokens, obtaining a document vector based on a plurality of frequencies associated with the plurality of tokens, obtaining one or more clusters of documents, each cluster associated with a plurality of documents and a cluster vector, determining a matching cluster from the one or more clusters based at least on the similarity between the document vector and the cluster vector of the matching cluster, and updating a database to associate the document with the matching cluster.
