Problems solved by technology

However, this result analysis method can only show the survey results as a whole, and it is difficult to distinguish the differences between the surveyed objects, let alone intuitively classify and cluster the surveyed objects.

Embodiment Construction

[0051] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0052] People look forward to displaying the questionnaire results in a more direct way, such as visualization. The described visual display method is to first represent the results of the questionnaire with high-dimensional vectors, and then use the distance between vectors to represent the differences between the surveyed objects. Each coordinate point is marked in the three-dimensional coordinate system, and the distance between the coordinate points represents the difference between the investigated objects. The non-linear dimensionality reduction technique (ISOMAP) can realize the dimensionality reduction of the data under the premise of keeping the inherent properties of the data unchanged. It is base...

Abstract

The invention discloses a method for realizing the visualization of the result of questionnaires based on a multiple choice question type and solves the problems that the conventional analysis technology of the results of the questionnaires can not distinguish the differences of investigated objects and the analysis result is not intuitive; the method of the invention comprises the following steps: the result of the questionnaire is processed so as to obtain the result of the questionnaire with high dimensional vector; on the premise that the distance of the result of the questionnaire with high dimensional vector is kept to be invariant basically, the result of the questionnaire with high dimensional vector is reduced to be the result of the questionnaire with low dimensional vector which is below 3 dimensions; according to the result of the questionnaire with low dimensional vector after the dimension is reduced, coordinate points are marked in a selected coordinate system so as to obtain a display image of the result of the questionnaire; the invention uses the non-linear dimension reduction technique to convert the high-dimensional vector into the low-dimensional vector used for displaying the coordinate, can reflect the difference of the investigated objects visually and carry out classification and clustering to the investigated personnel based on the vision, thus realizing the visualization display of the result of the questionnaire.

Description

technical field [0001] The invention belongs to the field of information technology, and relates to a method for realizing visualization of high-dimensional data, in particular to a method for realizing visualization of how to convert high-dimensional data larger than 3 dimensions into low-dimensional data below 3 dimensions. Background technique [0002] Multiple-choice questionnaire is a commonly used questionnaire in current market research. It directly investigates units or individuals by designing multiple-choice questions. It has been adopted by more and more enterprises, companies and consulting organizations because of its conciseness, popularity, objectiveness, truthfulness, fast feedback and good confidentiality. The commonly used method for analyzing the results of questionnaires is to count the total number of choices of each option in the questionnaire one by one, and then divide the number of times by the number of copies of the questionnaire to get the number ...
