Embodiment 1

[0043] An embodiment of the present invention provides an ontology matching method. figure 1 It is a schematic flow diagram of an ontology matching method according to an embodiment of the present invention; as figure 1 As shown, the ontology matching method includes:

[0044] Step 101: Obtain the first word vector corresponding to the first element in the first element set of the first ontology based on the first word vector model belonging to the first language, and obtain the word vector of the second ontology based on the second word vector model belonging to the second language. The second word vector corresponding to the second element in the second element set; the first element is any element in the first element set, and the second element is any element in the second element set .

[0045]Step 102: Translate the first element in the second language to obtain a third element, and translate the second element in the first language to obtain a fourth element.

[0046...

Embodiment 2

[0068] The embodiment of the present invention also provides a body matching device. image 3 It is a schematic diagram of the first composition structure of the body matching device according to the embodiment of the present invention; image 3As shown, the device includes: word vector obtaining unit 31, translation unit 32, splicing unit 33 and matching unit 34; wherein,

[0069] The word vector obtaining unit 31 is configured to obtain the first word vector corresponding to the first element in the first element set of the first ontology based on the first word vector model belonging to the first language, based on the second word belonging to the second language The vector model obtains the second word vector corresponding to the second element in the second element set of the second ontology; the first element is any element in the first element set, and the second element is the second any element in the element set;

[0070] The translation unit 32 is configured to re...

Embodiment 3

[0081] The embodiment of the present invention also provides a body matching device, Image 6 It is a schematic diagram of the hardware composition structure of the ontology matching device according to the embodiment of the present invention, such as Image 6 As shown, the ontology matching device includes a memory 42, a processor 41, and a computer program stored on the memory 42 and operable on the processor 41. When the processor 41 executes the program, it realizes: The first word vector model of the first ontology obtains the first word vector corresponding to the first element in the first element set of the first ontology, and obtains the second element in the second element set of the second ontology based on the second word vector model belonging to the second language The corresponding second word vector; the first element is any element in the first element set, and the second element is any element in the second element set; the first element is respectively Tran...

Abstract

The embodiment of the invention discloses an ontology matching method, device and computer storage medium. The method includes: obtaining a first word vector corresponding to the first element in the first element set of the first ontology, and obtaining a second word vector corresponding to the second element in the second element set of the second ontology; An element is translated according to the second language to obtain a third element, and the second element is translated according to the first language to obtain a fourth element; based on the first word vector model, the third element corresponding to the fourth element is obtained A word vector, obtaining a fourth word vector corresponding to the third element based on the second word vector model; splicing the first word vector and the fourth word vector to obtain a fifth word vector, and combining the second concatenating the word vector and the third word vector to obtain a sixth word vector; determining a matching relationship between the first ontology and the second ontology based on the fifth word vector and the sixth word vector.

Description

technical field [0001] The invention relates to text matching technology, in particular to an ontology matching method, device and computer storage medium. Background technique [0002] In order to solve the problem of intercommunication between heterogeneous ontologies, ontology matching can be used to determine the similarity of elements between ontologies, and the semantic relationship between entities in the ontology can be judged by the value of similarity, so as to realize the semantic relationship between ontologies. the mapping process between them. [0003] Usually, ontology matching can be realized by manual matching and automatic matching based on word similarity. In manual matching, domain experts use ontology editing software to discover the matching relationship between elements of ontologies according to their own domain knowledge. The automatic matching method determines the possible ontology matching relationship by calculating the similarity between conce...
