Standard terminology processing method for multi-strategy fusion in the field of oil and gas pipelines

Abstract

The invention discloses a multi-strategy integration standard terminology processing method for the oil and gas pipeline field and relates to the technical field of linguistic analysis and pipeline systems. The method is characterized by mainly comprising three modules as follows: 1) corpus preprocessing in the oil and gas pipeline field and text segmentation result optimization are performed; 2) term construction is realized in forms of a single algorithm and combination of multiple algorithms respectively; 3) obtained terms are filtered according to summarized rules, junk terms and conventional terms are rejected, and term processing results are optimized. The overall process is as follows: 1) corpus preprocessing in the oil and gas pipeline field and text segmentation result optimization; 2) a term construction method in the oil and gas pipeline field; 3) term construction optimization in the oil and gas pipeline field. With the adoption of the method, the segmentation accuracy is improved, and the term extraction precision ratio and the technical field correlation of final relative terms are improved.

Description

technical field [0001] The invention is a multi-strategy fusion standard term processing method oriented to the field of oil and gas pipelines, and relates to the technical fields of language analysis and pipeline systems. Background technique [0002] As a unified name for a specific thing or concept in a specific field, technical terms have a certain degree of recognition, domain and stability. For example, "pressure test" and "horizontal compressor" in the field of oil and gas pipelines are professional terms. At present, in the field of oil and gas pipelines, there is a lack of national or industry-developed terminology standards, and the terminology extraction in this field is all done manually. However, on the one hand, manual summarization of terms requires a large workload and consumes a lot of manpower; on the other hand, it is difficult to unify the standards and there are ambiguities. Therefore, how to use computers to objectively identify and efficiently constr...

Problems solved by technology

The method of using rules to deal with technical terminology has the advantages of high accuracy and small amount of calculation. The disadvantage is that it is difficult to formulate a complete set of rules to exhaust all linguistic phenomena, and in different professional fields, the construction rules of terminology are different. It is universal, and when the rules exceed a certain order of magnitude, it is necessary to additionally consider the conflicts between multiple rules
