A method for constructing a binary feature dictionary, comprising:
- extracting binary features from a corpus;
- calculating a preset statistic of each binary feature;
- and
- selecting a preset number of binary features in sequence according to the preset statistic to constitute the binary feature dictionary.
An apparatus for constructing a binary feature dictionary, comprising:
- one or more processors;
- a memory storing instructions executable by the one or more processors;
- wherein the one or more processors are configured to:
- extract binary features from a corpus;
- calculate a preset statistic of each binary feature;
- and
