Embodiment 1

[0064] Refer to figure 1 , Shows a flow chart of the steps of the human-machine dialogue method based on the knowledge graph in the first embodiment of the present invention. It can be understood that the flowchart in this method embodiment is not used to limit the order of execution of the steps. It should be noted that, in this embodiment, the human-machine dialogue device 2 is used as the execution subject for exemplary description. details as follows:

[0065] Step S100: Obtain the sentence input by the user.

[0066] Step S102: Perform word vector processing on the sentence.

[0067] Step S104, input the processing result into the convolutional neural network model.

[0068] In a specific embodiment, when the sentence input by the user is obtained, the sentence is subjected to word segmentation processing, and then the word segmentation processing result is input into the word2vector model to generate the corresponding word vector, and then the word vector is input to the convo...

Embodiment 2

[0087] See figure 2 , Shows a schematic diagram of the hardware architecture of the human-machine dialogue device of the second embodiment of the present invention. The human-machine dialogue device 2 includes, but is not limited to, a memory 21, a processing 22, and a network interface 23 that can communicate with each other through a system bus. figure 2 Only the human-machine dialogue device 2 with components 21-23 is shown, but it should be understood that it is not required to implement all the illustrated components, and more or fewer components may be implemented instead.

[0088] The memory 21 includes at least one type of readable storage medium, the readable storage medium includes flash memory, hard disk, multimedia card, card type memory (for example, SD or DX memory, etc.), random access memory (RAM), static memory Random access memory (SRAM), read only memory (ROM), electrically erasable programmable read only memory (EEPROM), programmable read only memory (PROM), ...

Embodiment 3

[0092] See image 3 , Shows a schematic diagram of program modules of the man-machine dialogue system of the third embodiment of the present invention. In this embodiment, the human-machine dialogue system 20 may include or be divided into one or more program modules. The one or more program modules are stored in a storage medium and executed by one or more processors to complete The invention can realize the above-mentioned human-machine dialogue method based on the knowledge graph. The program module referred to in the embodiment of the present invention refers to a series of computer program instruction segments capable of completing specific functions, and is more suitable for describing the execution process of the human-machine dialogue system 20 in the storage medium than the program itself. The following description will specifically introduce the functions of each program module in this embodiment:

[0093] The obtaining module 201 is used to obtain sentences input by t...

Abstract

The embodiment of the invention provides a man-machine dialogue method based on a knowledge graph. The man-machine dialogue method comprises the steps: obtaining statements input by a user; performingword vector processing on the statement; inputting a processing result into the convolutional neural network model; utilizing the convolutional neural network model to identify the intention of the statement; carrying out slot prediction on words in the statement; inputting the intention and the slot position prediction result into a knowledge graph; determining the corresponding relationship ofthe words according to the corresponding relationship among the entities in the knowledge graph; and searching the knowledge graph, and outputting the content corresponding to the relationship in theknowledge graph so as to realize man-machine conversation. Through the embodiment of the invention, questions of common knowledge and open fields can be answered, and dialogues can be actively initiated.

Description

Technical field [0001] The embodiments of the present invention relate to the field of big data, and in particular to a human-machine dialogue method, a human-machine dialogue device, a computer device and a readable storage medium based on a knowledge graph. Background technique [0002] The intelligent question answering system accurately locates the question knowledge required by the user in the form of one question and one answer, and provides users with personalized information services through interaction with the users. [0003] The traditional human-machine dialogue system is mainly based on the sequence to sequence (seq2seq) model. However, this type of model is trained based on historical corpus data to make immediate responses based on dialogue, but it cannot provide users with relevant knowledge answers. This solution attempts to realize a man-machine dialogue system through the combination of a knowledge graph and a task-based dialogue model. Summary of the invention...
