the corpus module is used for creating a standard library of addresses based on the obtained POI information and road doorplate information of the map application program; collecting sample address content, constructing a standard library sorting rule, performing character conversion on the sample address content by using a regular expression in the standard library sorting rule, and storing the converted sample address content into a created standard library; collecting customer service linguistic data, and removing non-standard words in the customer service linguistic data;
constructing a bag-of-words model and an address corpus by using a standard library;
performing word frequency vectorization processing on the objects in the corpus according to the character semantics to obtain semantic word frequency vectors;
the fault hotline module is used for carrying out voice conversation with a user, acquiring the corpus content to be detected in the conversation, cleaning the corpus content to be detected, and carrying out word frequency vectorization processing to obtain a semantic word frequency vector of the corpus content to be detected;
the matching module is used for calculating the similarity between the semantic word frequency vector of the corpus content to be detected and each object in the corpus, sequencing the similarity and identifying the corpus object with the maximum similarity;
verifying whether the matching result is accurate; and performing fault processing according to the address characteristics of the identified corpus object.
10. An electronic device, wherein the electronic device comprises:
a processor; and the number of the first and second groups,
a memory storing a computer executable program that, when executed, causes the processor to perform the method of any of claims 1-8.
11. A computer readable storage medium, wherein the computer readable storage medium stores one or more programs which, when executed by a processor, implement the method of any of claims 1-8.
