Description

Technical Field

[0001] The present invention relates to the technical field of information collection, and in particular to a method and device for visual information collection based on dialog flow. Background Art

[0002] The Q&A system generally implements the Q&A flow by writing code or other means to ask questions to users (i.e., the information collection object). After the user answers, the answer is parsed and the Q&A pair is stored for the Q&A survey party to view and use. The questionnaire system generally allows users to build forms in a visual way. After the user (i.e., the information collection object) fills in the form, the Q&A content is stored for the survey party to view and use.

[0003] The advantage of the question-and-answer system is that it is built in code, and the construction method is flexible. It can be built into a question-and-answer robot. The disadvantage is that it takes time to write code for the question-and-answer survey party to propose a collection process. Once the number of users increases, it is impossible to respond to the needs in a timely manner, and it is impossible to visually build the collection content. The advantage of the questionnaire system is that it is convenient for users to visually build the collection content without writing code. The disadvantage is that it cannot be displayed in the form of a dialogue flow, that is, it cannot be built into a question-and-answer robot.

[0004] Both of the above two information collection methods cannot realize a visual, interactive, and quickly editable information collection system at the same time. Summary of the invention

[0034] See also Figure 1 , 2An embodiment of the present application provides a method for collecting visual information based on a dialog flow, comprising the following steps:

[0035] Step S101, obtaining an uploaded questionnaire format file, wherein the questionnaire format file contains editable query rules, and the query rules include question ID, question type, question description, question options and jump logic.

[0036] Specifically, the present invention uses a questionnaire format file, preferably an Excel file, to design the question flow. Figure 3 Each question or logical jump is a cell or row. Each column of the Excel table contains but is not limited to the following query rules: question ID, question description, question type, question options / range and jump conditions. The question types include single-choice questions, multiple-choice questions, roller questions and input box questions. Specific formats and tags in Excel are used to distinguish different types of inputs, such as roller questions, multiple-choice questions, input box questions and logical jump rules.

[0037] by Figure 3 For example, the fixed columns are AP, with a total of 16 columns. The first column is the question id, in the format of question + serial number; the second column is the remarks of the question; the third column is the question content; the fourth column is the key corresponding to the question, and the key needs to be unique; the fifth column is the options; the sixth column is the option description; the seventh column is the population description; the eighth column is the hit rule; the ninth column is the question type, including single choice, multiple choice, single roller, double roller, input box, etc. The overall type is divided into roller question data, multiple choice question data and input box data according to the data structure; the tenth column is the jump logic, that is, if a certain option is selected, jump to a certain question. When the question type is an input box or roller question, the column indicates which question to jump to after answering the question; the eleventh column defaults to the next question; lower, upper, step, start_index, and unit in columns 12-16 are related information of the roller question; columns 16 and onwards are and conditional logic.

[0038] The information investigator is allowed to upload the above-designed Excel file through a secure interface. The computer system verifies the uploaded Excel file to ensure that its format is correct and meets the preset standards.

[0039] Step S102: parsing the questionnaire format file to obtain structured format data, and storing the structured format data in a database.

[0040] Specifically, the computer parses the Excel file, and the parsed state information is converted into structured format data and stored in the database for subsequent calls. The format data stored in the database includes logical jump information and question data information. Among them, the logical jump information defines the rules for how to change the current state or turn to the next state according to the user's (i.e., the information collection object) selection or input. The question data information is the specific question and possible answer form, which is divided into three categories: roller question data, multiple choice question data, and input box data.

[0041] The "rule_data" data in the database is used to store logical jump rules. Each entry contains one or more trigger conditions and corresponding jump targets. The "scroll_question_dict_data" data is used to store relevant information about scrolling questions (for example, adjusting the date, time, etc. to be selected by scrolling numbers), including minimum value, maximum value, starting value, step length, etc. The "select_question_dict_data" data is used to store the data of multiple-choice questions, including option lists, layout types, etc. The "input_question_dict_data" is used to store information about text input boxes, such as prompt text, etc.

[0042] Step S103, initialize the list of rules to be queried and the list of questions that have been asked, retrieve the structured format data in the database to obtain the first entry question of the questionnaire, and update all the query rules under the branch path where the first entry question is located to the list of rules to be queried.

[0043] Specifically, this step uses the list of rules to be queried and the list of questions that have been asked to implement dynamic question flow management. The list of rules to be queried and the list of questions that have been asked contain 0 query rules at the time of initialization. The first entry question of the questionnaire is obtained by retrieving the structured format data in the database, and all query rules under the branch path where the first entry question is located are updated to the list of rules to be queried. See Figure 4, the jump logic of the state machine of the questionnaire divides the entire question process into several branch paths. The first branch path is: Question 1->Question 2->Question 3->Question 4, the second branch path is: Question 5->Question 6, and the third branch path is Question 6. The jump logic is: Option 1 of Question 4 jumps to Question 5, and Option 2 of Question 4 jumps to Question 6. Among them, Question 1, Question 5, and Question 6 are the starting state nodes of the three branch paths, that is, the entry questions. After the list of rules to be queried in this step is initialized, preferably, the query rules corresponding to the four questions of Question 1->Question 2->Question 3->Question 4 of the first branch path are first updated to the list of rules to be queried. The reason for this design is that Question 4 is the last question node of the first branch path, and the direction of subsequent questions can only be determined based on the user's answer. Therefore, all questions cannot be updated to the list of rules to be queried, which will cause confusion in the query logic.

[0044] Step S104, traverse each query rule in the list of rules to be queried, generate corresponding questions or jump to the branch path where the second entry question is located, delete the traversed rules from the list of rules to be queried, and add the asked questions and user answers to the list of questions that have been asked.

[0045] Specifically, traverse each query rule corresponding to question 1->question 2->question 3->question 4 under the first branch path. If the current query rule is to ask a question, search the database for the option content corresponding to the question according to the key value of the current query rule, and generate the corresponding question for the user. Figure 4 Take this as an example to illustrate. The query rules corresponding to Question 1, Question 2, and Question 3 are all questions. According to the key value key of the query rule corresponding to Question 1, the option content "fever", "cough", and "throat pain" corresponding to Question 1 is searched in the database to generate a multiple-choice question 1. The user will select the corresponding option for Question 1, and the system will add Question 1 and the options answered by the user to the list of questions that have been asked. At this point, the query rule corresponding to Question 1 has been traversed, so it will be deleted from the list of rules to be queried.

[0046] If the current query rule is a logical jump (i.e., the query rule corresponding to question 4), then the next question may jump to question 5 or question 6 based on the user's answer and the jump logic (option 1 of question 4 jumps to question 5, option 2 of question 4 jumps to question 6). Figure 4For example, some logical jumps need to be judged in combination with the previously asked questions, user answers and jump logic to determine the question to jump to. After determining whether the second entry question is question 5 or question 6, all query rules under the branch path where the second entry question is located are updated to the list of rules to be queried, and then each query rule under the branch path where the second entry question is located is traversed in the same way as the first branch path. This will not be repeated here.

[0047] Furthermore, after each user answers, each query rule in the list of rules to be queried is checked to determine whether there is a query rule that meets the conditions of the new question. If so, the query rule of the new question is added to the list of rules to be queried, and the option content corresponding to the new question is searched in the database according to the key value of the query rule of the new question, and the corresponding new question is generated for the user. For example: if a query rule satisfies the user's answer "fever", "diarrhea", and "dehydration", a new question "Have you ever been tested for malaria parasites" needs to be added.

[0048] According to step 104, the list of rules to be queried is traversed. When the list of rules to be queried is empty, it means that all necessary information has been collected, and the conversation can be ended or the next operation can be entered.

[0049] This embodiment constructs a visual, conversational, and editable questionnaire information collection method by using a state machine algorithm. The questionnaire collection method simplifies the construction process of a complex state machine, can realize the conversation function of a question-and-answer robot, meets the needs of users to freely configure question-and-answer questionnaires, improves the efficiency of conversation collection, and adapts to the needs of various application scenarios.
