SYSTEM AND METHOD FOR SOCIAL EVENT DETECTION

摘要

A computer-implemented method, computer program product, and systems for event detection. The computer system for event detection includes an interface component configured to receive data entries from a social media data storage wherein the data entries have associated time values and location values. The received data entries are stored in a data storage component. A cluster creator of a clustering component can create a cluster with cluster data entries wherein the cluster data entries are received data entries having time values within a range of a time interval and having location values within a range of a location interval. A cluster evaluator can then determine a cluster value for the cluster by computing an event- specific cluster feature vector as input to a machine learning algorithm wherein the machine learning algorithm calculates the cluster value. If the cluster value exceeds an event detection threshold value an event is detected.
