Abstract:
In a distributed computer system, a computer-implemented method for automatic rating a raw data file for objectionable content, wherein said raw data file is a hypermedia file, a text file, an audio file, or an image file, said method comprising the steps of:preprocessing said raw data file to create semantic units representative of semantic contents of said raw data file; comparing said semantic units with a content rating repository comprising semantic entries and corresponding content ratings; assigning content rating vectors to said semantic units based on said comparing step; and creating a modified data file incorporating rating information derived from said content rating vectors, wherein when said raw data file is an audio file and said modified data file is a modified audio file, said preprocessing step further comprising the steps of: using a voice recognition system to create text data from said audio file; creating an audio-to-text correlation between a location in said text data and a corresponding location in said audio file; and parsing said text data into said semantic units.
