Problems solved by technology

[0004] Because the term aliases of entities in the field will continue to increase and change, and the experience of experts is not always correct, purely based on experience will make the basis for synonymous judgment insufficient, not authoritative enough, and it is difficult to evaluate the accuracy of synonymous judgment

Embodiment 1

[0084] figure 1 It is a flow chart of a proof-seeking method for synonymous discrimination of terms in Embodiment 1 of the present application. This embodiment of the present application is suitable for finding evidence for synonymous discrimination of a pair of terms, so as to perform synonymous judgment based on the evidence for synonymous discrimination. In this case, the method is executed by a device for identifying synonyms of terms, which is implemented by software and / or hardware, and is specifically configured in an electronic device with a certain data computing capability.

[0085] Such as figure 1 A proof-seeking method for synonymous discrimination of an entry is shown, including:

[0086] S110. Obtain the entry pairs to be synonymously determined and the data source of the field to which the entry pairs belong.

[0087] The entry pair to be synonymously determined includes two entries, and this embodiment does not limit the length, language, field, and type of ...

Embodiment 2

[0101] figure 2 It is a flow chart of a proof-seeking method for synonymous entry discrimination in Embodiment 2 of the present application. This embodiment of the present application is optimized on the basis of the technical solutions of the foregoing embodiments.

[0102] Optionally, refine the operation "according to whether the term pair appears in each text of the multi-paragraph text, calculate the correlation degree of the term pair" to "according to whether the term pair appears in each text of the multi-paragraph text, calculate The co-occurrence probability of the entry pair and the occurrence probability of each entry in the entry pair; according to the co-occurrence probability of the entry pair and the occurrence probability of each entry, calculate the correlation degree of the entry pair", providing a Calculation method of correlation.

[0103] Such as figure 2 A proof-seeking method for synonymous discrimination of an entry is shown, including:

[0104] S...

Embodiment 3

[0123] image 3 It is a flow chart of a proof-seeking method for synonymous entry discrimination in Embodiment 3 of the present application. This embodiment of the present application is optimized on the basis of the technical solutions of the above-mentioned embodiments, and provides another calculation method of correlation .

[0124] Optionally, after the operation "if the correlation degree of the entry pair satisfies the set condition, use the co-occurring text segment of the entry pair as the synonymous discrimination evidence of the entry pair", add "according to each of the synonymous discrimination evidence The authoritative degree of the source works, determine the weight of each source work; according to the relevance of the entry pair in each source work and the weight of each source work, calculate the entry pair in each source work According to the weighted correlation degree in each source work, sort the synonymous discrimination evidence of multiple source wor...

Abstract

The invention discloses a vocabulary entry synonymy discrimination evidence searching method and device, equipment and a storage medium, and relates to the technical field of knowledge maps. Accordingto the specific implementation scheme, the method comprises the steps of obtaining entry pairs to be subjected to synonymy judgment and data sources of fields to which the entry pairs belong; dividing texts in the data source according to set granularity to obtain multiple segments of texts; calculating the relevancy of the entry pairs according to whether the entry pairs appear in each text of the multiple texts or not; If the relevancy of the entry pairs meets a set condition, taking text segments co-occurring with the entry pairs as synonymous judgment evidences of the entry pairs. According to the embodiment of the invention, the segment of text in which the possible synonymous entry pair appears is extracted as the synonymous discrimination evidence, so that preliminary synonymous discrimination is carried out according to co-occurrence of the entry pair, and the accuracy and authority of the synonymous discrimination evidence are improved.

Description

technical field [0001] This application relates to computer technology, especially to the field of knowledge map technology. Background technique [0002] In some industries, there are many aliases for terms describing entities in the industry, and the colloquial descriptions also vary greatly. For example, in the medical field, there are many standard names and aliases for entities such as inspection, surgery, clinical practice, drugs, and diseases. For example, colds and upper respiratory tract infections describe the same disease, and pregnancy-induced hypertension and gestational hypertension describe the same disease. [0003] When implementing a smart project, it is necessary to unify the standard name and alias of the same entity so that the project can run successfully. At present, experts in the field directly judge whether two terms are synonymous through experience. [0004] Because the term aliases of entities in the field will continue to increase and change,...
