METHOD AND SYSTEM FOR CROWD DETECTION

摘要

A computer implemented method, computer program product and computer system for crowd detection. The computer system (1000) receives through an interface (1006) a plurality of user generated data records from a social media data storage (SMDS1, SMDS2) component, wherein a user generated data record comprises a text portion. A location extractor (1001) extracts location information from a subset of the user generated data records being associated with geographic locations. A time identifier (1002) identifies in the subset time information being associated with the extracted location information. A trained machine learning system (1004) an indicator for crowd formation, wherein the indicator is an output of the machine learning system in response to an input pair of associated location information and time information.

1. A computer implemented method for crowd prediction, comprising:
receiving through an interface a plurality of user generated data records from a social media data storage component, wherein a user generated data record comprises a user-generated text portion; extracting location information from user-generated text portions of a subset of the user generated data records being associated with geographic locations; identifying in the subset time information being associated with the extracted location information; and detecting an indicator for crowd formation based on the extracted location and time information, using a machine learning system component.
