Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0027] Such as figure 1 As shown, the content is a context-based abstract sample information retrieval system of the present invention, including a word segmentation function module, a word meaning feature extraction module, an abstract word feature substitution representation module, an ST-IDF module and a classification module.
[0028] The abstract sample characterization method of the abstract sample information retrieval system includes the following steps:
[0029] Step 1: Use the word segmentation function module to segment the abstract words of the sample. When the sample completely uses abstract words to record information, it is impossible to segment the abstract words in the sample according to the dictionary or thesaurus. Therefore, this step only treats the abstract word as a string of ASCII characters. When the sample is a data link mes...
