Abstract:Computer-Assisted Interviewing (CAI) has been widely used in social survey research. Comparing with the general CAI system, this questionnaire survey system based on kinship network focuses on the design of the complex questionnaire, the construction of kinship network, and the analysis of the collected data. By using XML to express and store the complex questionnaire and answer data, this system provides researchers an efficient tool to design the complex questionnaire for in-depth interview and to localize the questionnaire into multiple languages so that it can be adapted to different cultural areas. An iterative algorithm is proposed for generating the diagram of kinship network. Based on this diagram, interviewers can efficiently and easily collect data with visualization interface of interviewing. The data analysis pre-processing generates the data matrices derived from the survey data in order that they can be easily imported into any statistical analysis software for further analysis. The proposed system can be employed in the research of family population structure analysis and social interaction between relatives and friends. Currently, this system has been utilized in several fieldwork sites in China and other countries and it satisfies the needs of social survey research.
