CREATING A SURVEY SAMPLE GROUP ACCORDING TO A DESIRED PARTICIPANT DISTRIBUTION IN REAL TIME

摘要

A balanced survey is automatically created in real time, that is, while potential survey participants are evaluated. A survey histogram is automatically re-balanced with each new entry accepted as a respondent. An individual fills out a questionnaire providing demographic and socio-economic data. A vector representation of that person, referred to as an entry, is created. A similarity value is calculated indicating the similarity between the vector representation and a histogram vector representing the makeup of the survey. The similarity value is calculated by taking a dot product of the entry vector representation and the histogram vector. The system then determines whether the similarity value is greater than a similarity threshold value. If the similarity value exceeds the threshold value, the entry vector is integrated into the histogram vector, that is, the individual becomes part of the survey group.

1. A method of creating a balanced survey group in real time, the method comprising:
creating a vector representation of an entry; calculating a similarity value indicating a similarity between the vector representation and a first histogram vector; determining whether the similarity value is greater than a similarity threshold; and integrating the entry vector representation into the first histogram vector, wherein the first histogram relates to a first goal.
