Embodiment Construction
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0024] Such as figure 1 A method for generating a power supply service special vocabulary is shown, and the method includes the following steps:
[0025] S1: Text preprocessing: Use punctuation to segment the input text, that is, a whole paragraph is segmented and segmented through the punctuation service;
[0026] S2: English and number extraction: English numbers are clearly distinguished, and the existing word segmentation algorithm is used to perform word segm...

The invention discloses a generation method for a lexicon special for power supply service. The method comprises the following steps that: carrying out text preprocessing; carrying out English and digit extraction; carrying out Chinese numeral and quantifier extraction; carrying out proper noun extraction; carrying out secondary word segmentation extraction, and setting extraction threshold valuesand weights; carrying out matching and weight annotation on the contents obtained by the secondary word segmentation extraction, and extracting corresponding segmented words through a model; carryingout ambiguity processing to form a final word segmentation extraction result; manually adding power grid proper nouns; and combining the final word segmentation extraction result with the power gridproper nouns to form the lexicon special for the power supply service. By use of the method, an exclusive field in a power system is imported to serve as a lexicon phrase for carrying out word segmentation extraction, the proper nouns are more effectively screened, and convenience is brought to entry segmentation and hot word extraction; various methods are combined to extract hot words, relevantassociative matching and weight annotation can be carried out so as to extract a final word segmentation lexicon; and the generation method more conforms to the hot word extraction requirements of thepower supply service, and hot word extraction accuracy and efficiency can be improved.
Description
technical field [0001] The invention belongs to the field of power supply services, and in particular relates to a method for generating a special lexicon for power supply services. Background technique [0002] The reform of the electric power system has been further deepened, the transformation and upgrading of the economic structure has been continuously strengthened, and the service standards for customers' electricity use have been increasingly improved. Customer service work order information is a valuable resource for power supply companies, from which management and leadership can learn about the deficiencies and existing problems in the company's service work. Customer complaints can be transformed into positive external pressure for enterprises to strengthen internal management. With the continuous improvement of the smart grid, marketing business data is developing on a massive scale. The existing different types of service work orders still use the traditional ...
