Embodiment

[0034] This example takes the Chinese-Thai bilingual dataset as an example, uses Python as the development language, and uses Pycharm software as the development environment.

[0035] refer to image 3 , a Chinese-Thai entity alignment method for cross-language knowledge graphs, including the following steps:

[0036] 1) Acquisition of bilingual datasets: Obtain Chinese-Thai bilingual alignment data from Wikidata, YAGO multilingual knowledge base or major Chinese-Thai bilingual websites. The datasets are all aligned Chinese-Thai bilingual sentences, and entities in Chinese sentences can be found in Find its relatively aligned entity in the Thai sentence, as shown in Table a, for example, the Chinese entity in the 1-A sentence in Chinese can find the aligned Thai entity in the 1-B sentence in Thai;

[0037] Table a Chinese-Thai alignment sentence data example

[0038]

[0039] 2) Construction and training of the machine translation model: construct the Transformer translat...

Abstract

The invention discloses a cross-language knowledge graph-oriented Chinese-Thai entity alignment method, which is characterized by comprising the following steps of: (1) bilingual data set acquisition;(2) machine translation model constructing and training; (3) entity extraction; and (4) entity translation and matching. The method can achieve bilingual entity alignment more effectively and more accurately, and solves the problem that the entity alignment degree of cross-language knowledge graph construction is low at present.

Description

technical field [0001] The invention relates to the field of artificial intelligence, belongs to cross-language knowledge graph technology, and specifically relates to a Chinese-Thai entity alignment method for cross-language knowledge graphs. Background technique [0002] With the continuous development of artificial intelligence, knowledge is particularly important in all fields of artificial intelligence. In recent years, the construction of cross-lingual knowledge graphs has become a hot research field. Although there are more and more sentences about bilingual alignment on the Internet, due to the low degree of alignment of these entities, the accuracy of multilingual entity alignment is often not satisfactory, and the construction of cross-lingual knowledge graphs is therefore limited. [0003] Entities mainly include person names, place names, organization names, etc. Generally speaking, the more commonly used entity alignment method at this stage is to first perform...
