Description
[technical field]
The present invention relates to the social computing data collecting field, be particularly related to a kind of system and collecting method thereof based on the interpersonal interaction's relation data between the wireless sensor network collecting sample of Zigbee, for social computing provides true, complete social relationships data.
[background technology]
Social computing is the interdisciplinary science that computer technology and theory of social science merge mutually, not only pays close attention to computer or the more application of information technology in social activities of broad sense; And research social knowledge, or use and the embedding of humane knowledge in computer or information technology more specifically, and then the variety of issue of understanding and discovery social science, study its rule of development and provide corresponding solution, to improve benefit and the level of social activities.
Under the specific environment of China's economic Social Transformation Period, the social class breaks up fast, new and old social contradications are interweaved, the public safety problems such as the unconventional burst Mass disturbance that may occur, public health event continue to bring out, directly affect social stability harmonious, become the significant problem of Chinese society's Faced In Sustainable Development, thereby these problems have been subject to government and educational circles shows great attention to.But existing relevant research concentrates on the aspects such as qualitative description analysis or case analysis mostly, lacks quantitative systematic Study, thereby is difficult to characteristics and the rule of these social concerns are carried out scientific description and research.Be subject to simultaneously the collection difficulty of interpersonal interaction's relation data of extensive, complexity, to prediction, intervention and the control of this class problem and propose more efficiently that policy becomes very difficult.Therefore how obtaining interpersonal interaction's relation data between colony studies above-mentioned complicated social concern and becomes very urgent.This is the science needs of researching and solving complicated social concern, is also to strengthen social stability, promotes the reality of the structure of harmonious society to need.
Data are accurately to portray the basis of social concern and the necessary condition of building technology platform as social computing with experiment.The same with natural science, the data of social science also need to obtain experiment, but different from Engineering Experimental, the experimental subjects of social experiment is people or tissue, due to social complexity, make conventional laboratory facilities be difficult to satisfy the needs of Social Science Research, feasible social experiment's means have the conventional methods such as social investigation, questionnaire, participant's observation at present.Yet these conventional methods all come with some shortcomings again, document (1) Wang Feiyue, once main forces, Mao Wenji, the meaning of social computing, development and research situation, e-Science forum, 2010.7; (2) Sheng Zhaohan, Zhang Jun, Du Jianguo etc., the social science experiment with computing is theoretical and use Shanghai Sanlian Bookstore, 2009.7; (3) Wang Feiyue, artificial social product, experiment with computing, parallel system---calculate the discussion of research about complex socioeconomic system, complication system and complexity science have relevant the elaboration in 2004.10.Document (1) points out, the conventional methods such as social investigation need to drop into huge human and material resources, financial resources and social relationships, and cost is high and be difficult to repetition; Secondly due to the existence of artificial subjective factor, the data that make acquisition are serious distortion often.Document (2) points out, conventional method stresses the aspects such as qualitative description analysis or case analysis more, lacks quantitative systematic Study, thereby is difficult to characteristics and the rule of these social concerns are carried out scientific description and research.Document (3) points out, conventional method needs playing an active part in of experimenter, may relate to individual privacy, affects people's normal life, so that morally is difficult to receive this type of experiment.
[summary of the invention]
The object of the present invention is to provide a kind of interpersonal interaction's relation data acquisition system and collecting method thereof, under the normal activity that does not disturb sample, collect accurately the interactive relationship data between sample.
To achieve these goals, the present invention adopts following technical scheme:
A kind of interpersonal interaction's relation data acquisition system comprises host computer, Zigbee telegon and a plurality of Zigbee node; The Zigbee node is used for the experimenter to be worn, and is used for gathering interpersonal interaction's relation data; The Zigbee telegon is connected with host computer, is used for collecting and uploading the information that the Zigbee node gathers.
