Embodiment Construction
[0012] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0013] In one embodiment of the present invention, a method for mining reasons based on dynamic stop words is provided, figure 1 It is a schematic diagram of the overall flow of the reason mining method provided by the embodiment of the present invention, the method includes: S101, converting the voices to be mined in the voice set to be mined into original texts, and using the original texts containing preset keywords as hit texts , taking the original text that does not contain the preset keyword as a miss text;
[0014] Wherein, the set of voices to be mined is a set of voices that need to be mined. The original text is the text directly converted from the speech to b...

The invention provides a reason mining method based on dynamic stopping words. The method comprises: converting the speech to be mined in a speech set to be mined into original text respectively; taking the original text containing a preset keyword as a hit text; taking the original text without the preset keyword as a missed text; converting the original text to be mined into an original text; and converting the original text into a hit text; calculating a first document frequency of each word in the hit text in all of the hit text and a second document frequency in all of the miss text, determining a stop word based on the first document frequency and the second document frequency; the stop word is filtered out from the hit text, the hit text after the stop word is filtered out is takenas the target text, and the reason corresponding to the preset keyword is mined from the target text. The invention improves the accuracy and efficiency of the cause mining.
Description
technical field [0001] The invention belongs to the technical field of speech analysis, and more specifically relates to a reason mining method based on dynamic stop words. Background technique [0002] In voice calls where customers conduct business consultation or customer service recommends services to customers through voice, there is a lot of information with business value, such as the specific reasons for "surrender", "cancellation" or "complaint", so from Haili Voice Mining out the specific reasons for user behavior is of great significance to the improvement of service quality. [0003] In the prior art, the excavation of the reason in the voice is generally performed by artificially listening to the voice, analyzing the voice, and then recording the reason in the voice. Due to the limited hearing ability of people, it is easy to miss and mishear, and the quality of voice playback equipment will also affect the effect of voice playback. And people's hearing is eas...
