Problems solved by technology

[0003] The existing question answering system can only provide a single reply to a certain question entered by the user, and it cannot optimize the reply to the question
That is, when the user is not satisfied with the reply to the current question, the existing question answering system cannot optimize the reply to provide the user with a more satisfactory reply

Embodiment 1

[0050] figure 1 A flow chart of the question answering evaluation method oriented to the question answering system provided by this embodiment is shown. It should be pointed out that the question answering system involved in the present invention does not specifically refer to a system that must have a relationship between "asking" and "answering", but generally refers to an interactive system with human-computer dialogue.

[0051] Such as figure 1 As shown, the method first obtains the response information of the current interaction input by the user in step S101. It should be pointed out that in different embodiments of the present invention, the response information obtained in step S101 of the method may be text information, voice information or body movement information, and the present invention is not limited thereto.

[0052] After obtaining the response information of the current interaction, the method will judge in step S102 whether the previous interaction betwee...

Embodiment 2

[0066] image 3 A flow chart of the question answering evaluation method oriented to the question answering system provided by this embodiment is shown.

[0067] Such as image 3 As shown, the method provided by this embodiment first obtains the response information of the current interaction input by the user in step S301, and judges in step S302 whether the previous interaction between the question answering system and the user is a dialogue interaction. It should be pointed out that the implementation principle and implementation process of step S301 and step S302 are the same as those of step S101 to step S102 described in the first embodiment, so they will not be repeated here.

[0068] In this embodiment, if the previous interaction between the question answering system and the user is a dialogue interaction, then in step S303, the method will use the preset positive thesaurus and the preset derogatory thesaurus to match the response information of the current interacti...

Embodiment 3

[0077] Figure 4 A flow chart of the question answering evaluation method oriented to the question answering system provided by this embodiment is shown.

[0078] Such as Figure 4 As shown, the method first acquires the response information of the current interaction input by the user in step S401. After obtaining the response information of the current interaction, the method judges in step S402 whether the previous interaction between the question answering system and the user is a dialogue interaction, and if so, generates an Weight change value. After obtaining the weight change value, the method updates the weight of the feedback information of the question answering system in the previous interaction according to the weight change value in step S404. If the previous interaction between the question answering system and the user is not a dialogue interaction, then this method does not perform any additional operations.

[0079] It should be pointed out that the imple...

Abstract

The invention relates to a questions and answers evaluation method and device for a questions and answers system. The method comprises the following steps of acquiring response information, namely acquiring current-interactive response information input from a user; and updating a weight, namely detecting whether the current interaction and previous interaction of the user is dialogue interaction or not, if yes, generating a weight changing value according to the response information, and updating the weight of feedback information output from the questions and answers system in previous interaction according to the weight changing value. By the method, the satisfaction degree of the user on each piece of feedback information can be quantitatively determined; when the user inputs the same question again, the questions and answers system can select the feedback information which the satisfaction degree of the user is relatively high according to the weight of each feedback information, and thus, the interaction process is more humanized.

Description

technical field [0001] The present invention relates to the technical field of human-computer interaction, in particular to a question answering evaluation method and device for question answering systems. Background technique [0002] The question answering system is to determine the relevant answers from a large number of text sets according to the user's questions. The answer here is not the entire document related to the question, but a part or a sentence of the document that more accurately meets the needs. The question answering system is different from information retrieval. Information retrieval can only locate relevant documents or web pages containing the query for the query submitted by the user, and the user needs to determine the useful information by himself. [0003] The existing question answering system can only provide a single reply to a certain question input by the user, and it cannot optimize the reply to the question. That is, when the user is not sat...
