Embodiment 1

[0030] figure 1 It is a flow chart of a matching degree determination method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of determining the matching degree between the target candidate replies and the historical dialogue, so as to determine the final reply from the candidate replies based on the matching degree. The method can be executed by a device for determining matching degree, and the device can be implemented by software and / or hardware. see figure 1 , the matching degree determination method provided in this embodiment includes:

[0031] S110. Based on the vector representation of the target candidate reply and the vector representation of at least one historical conversation, determine an association vector describing the association information between each historical conversation and the target candidate reply.

[0032] Wherein, the target candidate reply is the candidate reply to be scored.

[0033] Specific...

Embodiment 2

[0059] figure 2 It is a flow chart of a matching degree determination method provided in Embodiment 2 of the present invention. This embodiment is an optional solution proposed on the basis of the foregoing embodiments. see figure 2 , the matching degree determination method provided in this embodiment includes:

[0060] S210. Based on the dependency relationship among the components in the sentence, respectively update the vector representation of the target candidate reply and the vector representation of at least one historical dialogue, and generate a reply relationship vector and at least one dialogue relationship vector.

[0061] Specifically, the extraction of dependencies between components in a sentence can be realized based on a gated recurrent unit.

[0062] The vector representation of the target candidate reply is input to the gated recurrent unit, and the reply relationship vector is output; the vector representation of the historical dialogue is input to th...

Abstract

The embodiment of the invention discloses a matching degree determination method, device, equipment and medium, and relates to the field of intelligent dialogue. The method includes: based on the vector representation of the target candidate reply and at least one historical dialogue vector representation, determining an association vector describing the association information between each historical dialogue and the target candidate reply; based on the association vector, determining the target candidate reply and the historical dialogue match degree. Embodiments of the present invention provide a matching degree determination method, device, device, and medium, which realize matching degree of target candidate replies and historical conversations based on rich associated information between historical conversations and candidate replies.

Description

technical field [0001] The embodiments of the present invention relate to the field of intelligent dialogue, and in particular to a matching degree determination method, device, equipment and medium. Background technique [0002] In recent years, intelligent dialogue systems have begun to come into people's sight, and intelligent dialogue products have begun to bring more convenience and influence to people's lives. These dialogue systems intelligently generate responses to what the user says. [0003] A general dialogue system will first generate several candidate replies, and then calculate the Euclidean distance between the vector representation of the historical dialogue and the vector representation of the candidate replies, and determine the final reply from the candidate replies according to the Euclidean distance. [0004] However, the above-mentioned conversion from vector to numerical value leads to a large amount of information annihilation, which is not conduciv...
