Study On The Agricultural Science And Technology Information Quality Management Based On Network Sharing

Information Quality (IQ) is the prerequisite for the development of information sharing. From the essential characteristics of information sharing, information-sharing must solve the optimization of the quality of information and the highest efficiency of sharing level, in order to achieve the value of sharing information. As China's various types of technology information-sharing projects were promoted gradually, information quality issues of information-sharing are increasingly apparent, which has become the key impact factor of China's agricultural Science and technology information sharing in a prominent, and should be resolved instantly. Therefore, realize the basic characteristic of information quality management (IQM) in agricultural science and technology information sharing, to establish an effective management mechanism and to address IQ problems, are of great significance for the promotion of China's agricultural science and technology information sharing sustainable development.In this article, taking the information quality in China's agricultural information network construction and sharing practice of scientific and technological information as breakthrough, through the basic concept of quality management, theoretical understanding of network information resources and the current situation understanding in information-sharing projects of agricultural science and technology in combination, on the point of view of the internal structure of information quality and the idea of quality management, the special nature of information quality management in the agricultural science and technology information sharing was analyzed. On this basis, the concept of "Constraints of Information Quality (CIQ)" was introduced, and structuring CIQ mechanism as the framework, and the basic content of information quality in agricultural science and technology information sharing was developed. That is, by the study of IQ control, the analysis of IQ management countermeasures and IQ evaluation index system were carried out as the theoretical research. Finally, a case analysis was done for comparison and some proposals were given.In this article, the information quality management theory and methods was the first time used to analyze and solve the information quality issues in agricultural scientific and technological information sharing in the field of agriculture. The innovative researches were carried out as the following:1. A concept of "constraint of information quality" for information quality management in agricultural science and technology information sharing was put forward, and consisted as two respects, first, it is necessary to increase investment to eliminate deficiency, name the support constraint; Another one is the restrictive constraints for the factors affecting the quality of the information were set, to enable the sharing system in accordance with the intended direction. On the basis of the concept, in-depth analysis was carried out and CIQ mechanism was developed to ensure that the quality of information management is effectively implemented.2. The basic framework for information quality management in agricultural science and technology information sharing was proposed. It includes three parts: The information quality management strategy was studied ,which from macro and micro levels, and the information quality control was analyzed, which from the two aspects of data and databases, and the information quality evaluation indicators System was established ,which from the evaluation of information quality itself and the information quality management. These three points form a basically intact information quality control circulatory system.3. The basic quality characteristics in sharing information on agricultural science and technology under current network environment were revealed. From the form, content and effectiveness of IQ, combine expert investigations, it was concluded that the IQ basic features in the current agricultural science and technology information sharing were truthfulness, accessibility and practicality, etc. Therefore, the control measures of information quality management, strategy analysis and the selection of evaluation indicators should be pays close attention these three respects.4. The basic thinking for the evaluation of the information quality in agricultural scientific and technological information sharing were explored. Evaluation of the information quality should be carried out from the information quality evaluation and information quality management evaluation. As for the former, the evaluation indicator system should be developed according to the different needs (including the three levels, such as agricultural science and technology information overall assessment, specific subject areas and a certain subject areas); as for the latter, the evaluation indicator system should established according to macro-and micro-management of the information constraint to found the key impact of IQ and select the necessary elements of restraint and constraint indicators, to amend the constraints contents for achievement of an effective monitoring the implementation of information quality management.In the study, closely integrated with of the actual situation in China's agricultural science and technology information sharing, some views, methods and ideas were developed in expectations of providing the theoretical and practical guiding for the building of China's agricultural science and technology information sharing information and information quality management.
