Large scale video event classification

摘要

Systems and methods are provided herein relating to video classification. A text mining component is disclosed that automatically generates a plurality of video event categories. Part-of-Speech (POS) analysis can be applied to video titles and descriptions, further using a lexical hierarchy to filter potential classifications. Classification performance can be further improved by extracting content-based features from a video sample. Using the content based features a set of classifier scores can be generated. A hyper classifier can use both the classifier scores and the content-based features of the video to classify the video sample.
