    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 one or more user inputs, determining, based on the user inputs, an entity and a date range, obtaining one or more documents associated with the entity and with dates within the date range, the one or more documents being grouped into one or more clusters, and the clusters being grouped into one or more megaclusters, and presenting the one or more documents on one or more timelines, wherein the one or more documents are grouped into different megaclusters being presented in a visually distinct way. The method further allows for filtering of the one or more clusters based on a value associated with the one or more clusters.

    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.
