Abstract
Computer implemented method, system and computer program product for extracting salient keywords for videos. A computer implemented method for extracting salient keywords for videos includes extracting a set of candidate keywords from a text source of a video, assigning a salience value to each candidate keyword based on statistical information to provide a set of statistically significant keywords, exploiting additional cues that are available to the video and that can be used to further measure the significance of existing keywords or to extract new keywords, and selecting a set of salient keywords for the video based on the set of statistically significant keywords and the additional cues.

A computer implemented method for extracting salient keywords for videos, the computer implemented method comprising:
- extracting a set of candidate keywords from a text source of a video;
- assigning a salience value to each candidate keyword based on statistical information to provide a set of statistically significant keywords;
- exploiting additional cues that are available to the video;
- and
- selecting a set of salient keywords for the video based on the set of statistically significant keywords and the additional cues.
A system for extracting salient keywords for videos, comprising:
- a full text-based keyword extraction unit for extracting a set of candidate keywords from a text source of a video, and for assigning a salience value to each candidate keyword based on statistical information to provide a set of statistically significant keywords;
- additional information extraction units for exploiting additional cues that are available to the video;
- and
- a salient keyword selection unit for selecting a set of salient keywords for the video based on the set of statistically significant keywords and the additional cues.
A computer program product, comprising:
- a computer usable medium having computer usable program code for extracting salient keywords for videos, the computer program product comprising:
- computer usable program code configured for extracting a set of candidate keywords from a text source of a video;
- computer usable program code configured for assigning a salience value to each candidate keyword based on statistical information to provide a set of statistically significant keywords;
