This article introduces how to use nodejs BOT SDK to develop question-and-answer skill templates, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Question and answer skills template

Q & A skills template is designed for Q & A skills, such as knowledge Q & A, life common sense questions and so on. This article describes how to quickly build question and answer skills from the interaction and deployment of question and answer skills.

The interaction Model of question and answer skill template

Question-and-answer skills interact with users by selecting a question from the list of question banks and providing four options, one of which is correct. The user answers the question by saying the order of the correct options.

The following takes the question and answer skills of ancient poetry as an example to describe the interaction process between question and answer skills and users. The skill selects a poem from the list of ancient poems and asks the user to name the author of the poem, and then read out the four author options in turn. The user says the correct order of the author's options, and the skill records the user's score when the answer is correct. The process of skill interaction is as follows:

Users: open the question and answer of ancient poetry

Skills: [skills welcome]. Start answering the questions. The first question: who is the author of the wild weeds growing in chaos in Guyuan every year when spring comes to flourish and autumn comes to withered and yellow? 1, Li Bai 2, Bai Juyi 3, du Fu 4, Liu Zongyuan

User: second

Skill: get one point for correct answer. The current score is one point. Question number two.

The skill of selecting questions from the question bank can put an end to the repetition of questions and the repetition of answers. Developers only need to update the list of topics and the corresponding skill configuration information to generate new skills and publish them on the DuerOS DBP platform. The question bank is stored as follows, in which the correct answer needs to be placed in the first place of the answer in the following format.

{'question': ['correct answer', 'wrong answer',],}

The above examples of questions and answers in ancient poems are shown in the question bank as follows:

The first question: who is the author of the wild weeds growing in chaos in Guyuan every spring and autumn? ['Bai Juyi','Li Bai','du Fu', 'Liu Zongyuan', question 2: the sun is setting against the mountains, and the Yellow River flows toward the sea. ['ascend the Stork Tower',',],}

Among them, the correct answers "Bai Juyi" and "climbing the Stork Tower" are placed in the first place, but when giving questions to users, the order of the options will be adjusted.

Instructions for the use of the template:

There must be a correct answer in the answer.

The answer options for each question can be 3, 4, 5, and there is no limit to the total number of options.

Each question must be answered by the option serial number, for example, the user must say "first" and "second", and cannot use "yes", "right", "wrong", "no" and so on.

The process of using templates to develop skills

Note that the following process of creating new skills and configuring intentions can be achieved by importing http://dbp-cfc.cdn.bcebos.com/download/trivia.zip on the skills platform-> create skills-- > reference skills-- > Import skills page.

New skills

For more information on creating new skills, see Custom skill creation.

Configuration intention

For details of intention configuration, see intent, common expressions and slots

The question and answer skill template needs to create two intentions, namely, the intention to answer the question and the intention to restart the question and answer. The intention to answer the question is shown in the following figure:

The intention to restart the question and answer is shown in the following figure:

Configure skill service deployment

The question and answer skills template uses CFC to deploy skills services. For more information on deploying skill services using CFC, please see Baidu Cloud CFC.

Modify CFC function code

The question and answer skills template uses questions.js to configure the question bank. Developers need to download the complete zip package of the skill CFC function to develop locally, and upload the function zip package for release after the development is completed. The specific process is as follows:

In the CFC console, create a function through the template, and select the node.js DuerOS Bot SDK template

After the function is generated, click the download complete ZIP package link in the function console to download the package.

Extract the package locally

Copy the https://github.com/dueros/bot-sdk-node.js/blob/master/samples/trivia/questions.js file to the package folder

Replace the index.js file in the package folder with https://github.com/dueros/bot-sdk-node.js/blob/master/samples/trivia/index.js

Repackage all files in the package folder into zip files

Upload the zip package in the function console and save it

For instructions on CFC operation, please see function calculation CFC.

At this point, the question and answer skills have been developed. Developers can test their skills on the simulation test page of the skills open platform.
