Embodiment Construction
[0031] 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:
[0032] Such as figure 1 As shown, the implementation method comprises the following steps: comprising the following steps:
[0033] Step 1: collect the work order data of the power system and convert it into a text format, use the seven-step method to construct the ontology, and divide it into multiple text domains according to the text meaning attributes;
[0034] Step 2: Take the work order as the unit, perform word segmentation processing on the work order text data;
[0035] Step 3: Group the text fields;
[0036] 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;
[0037] Step 5: Filter invalid words according to the invalid vocabulary list, and filter out invalid w...

The invention provides a database construction method of power information operation and maintenance system based on a knowledge map, which forms a graph database through textualization and word segmentation of electric power system work order data, classification through similarity degree, and storage. The invention improves the effective utilization of the electric power data, exerts the value of data hiding, improves the intelligent application level of the electric power network, changes the low-dimensional and mutually isolated information display mode in the past, models the electric power information data, and can more intuitively present the correlation among electric power knowledge. On this basis, The knowledge base of power information operation and maintenance system can be constructed to transform the historical operation and maintenance data into knowledge, to support users to consult and solve problems on line independently, to realize intelligent question answering, toimprove the efficiency of operation and maintenance, and to play an important role in power network operation and maintenance work, on the basis of which the knowledge model optimization storage technology in power information operation and maintenance domain can be completed.
Description
technical field [0001] The invention belongs to the field of electric power operation and maintenance management, and in particular relates to a database construction method for an electric power information operation and maintenance system based on a knowledge map. 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 nece...
