Problems solved by technology

[0004] There are many technical difficulties in building a public knowledge map for the power industry, such as weak analysis of operation and maintenance knowledge, the overall value of data resources remains in the extensive stage, the data resources have not been effectively transformed into knowledge assets, and a virtuous cycle of knowledge has not been formed. The ability to support business needs and the ability to promote management changes are weak, which hinder the organization and construction of power operation and maintenance knowledge graphs

Embodiment Construction

[0039] In order to make the features and advantages of this patent more obvious and easy to understand, the following special examples are described in detail as follows:

[0040] Such as figure 1 As shown, the implementation method comprises the following steps: comprising the following steps:

[0041] Step 1: Collect the work order data of the power system, convert it into a text format, and divide it into multiple text domains according to the text meaning attribute;

[0042] Step 2: Take the work order as the unit, perform word segmentation processing on the work order text data;

[0043] Step 3: Group the text fields;

[0044] Step 4: Carry out domain word segmentation processing for each text domain, and use the word segmentation method based on string matching to segment the content of each group into words;

[0045] Step 5: Filter invalid words according to the invalid vocabulary list, and filter out invalid words and sensitive words;

[0046] Step 6: Compare the e...

Abstract

The invention provides a power operation and maintenance information knowledge graph construction method. A deep learning algorithm is introduced in construction of a power field knowledge graph; andtwo major machine learning tasks of named entity identification and entity relationship extraction are adopted for solving two difficult problems of knowledge unit extraction and knowledge unit relationship extraction. The effective utilization of power data is improved; the hidden value of the data is exerted; the intelligent application level of a power network is improved; and based on knowledge representation of the knowledge graph, a low-dimensional and mutually isolated information display mode in the past is changed, and association among power knowledge is presented more intuitively. Apower information operation and maintenance system knowledge library is constructed; historical operation and maintenance data is converted into knowledge; online autonomous consultation and problemsolving of a user are supported; intelligent question and answer are realized; the operation and maintenance efficiency is improved; important values are exerted in power network operation and maintenance work; and based on this, a power information operation and maintenance field knowledge graph optimization storage technology is finished.

Description

technical field [0001] The invention belongs to the field of electric power operation and maintenance management, and in particular relates to a method for constructing a knowledge map of electric power operation and maintenance information. Background technique [0002] The current power operation and maintenance customer service system is faced with the voices of a large number of customers from all sides every day. Enterprises and individual users conduct business consultation, Fault warranty, complaints, reports, suggestions, opinions and praise, power grid information, policy subscription, etc., put forward higher requirements for service provision and consumption. It is necessary to timely and accurately understand the voice of customers, and provide the best service in the shortest time To meet the needs of customers; at the same time, customers require more friendly, convenient and fast use of the services we provide. To this end, it is necessary to continuously imp...
