Engineering technical and economic knowledge retrieval platform based on knowledge graph and method thereof

Abstract

The invention relates to an engineering technical and economic knowledge retrieval platform based on a knowledge graph and method thereof. The platform comprises a technical and economic knowledge library, a semantic processing unit, and an interaction unit, and the technical and economic knowledge library and the interaction unit are connected with the semantic processing unit. The technical andeconomic knowledge library is used for storing project management knowledge, technical and economic knowledge, cost knowledge, engineering technology knowledge, law and regulation knowledge and actualcases; the semantic processing unit generates a corresponding retrieval formula according to a retrieval statement input by a user so as to retrieve from the technical and economic ontology knowledgebase to obtain a related knowledge graph; and the interaction unit is used for a user to carry out input operation of retrieval statements, and visually presenting the related knowledge graph obtained by retrieval to the user. Compared with the prior art, the technical and economic knowledge library is constructed, semantic retrieval is combined, a user can accurately and rapidly retrieve neededknowledge, and engineering professional cooperation efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of intelligent retrieval, in particular to a knowledge graph-based engineering technology knowledge retrieval platform and a method thereof. Background technique [0002] As an important infrastructure of the power system, the power transmission and transformation project has the characteristics of strong comprehensiveness and high collaboration. The promotion process of power transmission and transformation projects involves many disciplines, requiring division of labor and collaboration among different disciplines. However, in power transmission and transformation projects, most technical and economic personnel are proficient in their own professional knowledge, but have little knowledge of other fields of knowledge. This situation will limit the improvement of professional collaboration efficiency in engineering. At the same time, project participants also lack effective cross-industry knowledge learning...

Problems solved by technology

However, in power transmission and transformation projects, most technical and economic personnel are proficient in their own professional knowledge, but have little knowledge of other fields of knowledge. This situation will limit the improvement of professional collaboration efficiency in the project

At the same time, project participants also lack effective cross-industry knowledge learning channels. Knowledge on the Internet is often fragmented and inaccurate, and the feasibility of classroom learning is not high.

The lack of systematic knowledge framework makes it impossible for relevant personnel to select learning content in a targeted manner, which can easily discourage their enthusiasm and ultimately reduce the effectiveness of learning

With the development of my country's electric power industry, the number of completed power transmission and transformation projects continues to increase, and a large amount of engineering data has been accumulated. However, due to the lack of a feasible data storage structure, project personnel cannot accurately and quickly obtain the required data, and it takes a lot of time. time spent searching and reading
