Embodiment Construction

[0060] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] Some terms and explanations thereof involved in the present invention are listed as follows:

[0062] Intention: In the task-based dialogue system, sentences are divided into different categories according to their functions according to different tasks. Each category expresses a different meaning, and each category is an intention.

[0063] For example: "I want to book a flight ticket from Beijing to Shanghai" is a user expressing his needs, which can be defined as the intention of "informing"; Ticket information, this can be defined as a "request" intent.

[0064] It is worth noting that different companies may use different words to express the same intent in different scenarios. For example, the intent of "request" may be named "question" by other companies, and may also be named "obtain information".

Abstract

The invention provides a cross-domain dialogue strategy migration method, which comprises the following steps of: processing an input user input dialogue so as to map a corresponding target domain dialogue state; mapping the target domain dialogue state into a source domain dialogue state; based on a preset dialogue strategy of the source domain, processing the dialogue state of the source domainto obtain a corresponding dialogue reply of the source domain; and mapping the source domain dialogue reply into a target domain dialogue reply. The invention also provides a cross-domain dialogue strategy migration device, equipment and a readable storage medium. The technical problems that an existing conventionally constructed dialogue system is difficult to maintain, the cost of manual data annotation is high, data are repeatedly annotated, and annotated data are difficult to apply in a cross-domain mode are solved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a migration method, device, device and readable storage medium of a cross-domain dialog strategy. Background technique [0002] Dialogue systems are an important part of the field of human-computer interaction. Currently, conventionally constructed dialogue systems mainly include: dialogue systems built using rules, dialogue systems based on supervised learning, and dialogue systems based on reinforcement learning. [0003] The dialogue system built by using rules appeared the earliest. This kind of system is easier for people to understand and control. Its disadvantage is that developers need to enumerate all cases and formulate rules for each case to pre-judge. When the actual scene is complex and the number of rules accumulated is large, it is easy for the rules to conflict with each other, making the system difficult to maintain. This kind of system is difficult t...
