The article examined the pattern and distribution of the secondary information, systems and services in China. The objects of the study include the governments role and relevant policies, the distribution of discipline-oriented systems, the development from printed material to machine readable to data bases and the influence of transition to a market economy on the operation of current systems. The study showed that the structure of the secondary information systems was established and the government has played a dominant role in developing and maintaining the systems. The article further discussed the challenge of a new social and economic environment to the systems and the possible expansion of new products and services. 相似文献

Experiments were conducted to explore the impact of combining various components of eight leading information retrieval systems.
Each system demonstrated improved effectiveness through the use of blind feedback, also known as pseudo-relevance feedback, a form of query expansion. Blind feedback uses the results of a preliminary retrieval step to augment the efficacy of a
secondary retrieval step. The hybrid combination of primary and secondary retrieval steps from different systems in a number
of cases yielded better effectiveness than either of the constituent systems alone. This positive combining effect was observed
when entire documents were passed between the two retrieval steps, but not when only the expansion terms were passed. Several
combinations of primary and secondary retrieval steps were fused using the CombMNZ algorithm; all yielded significant effectiveness
improvement over the individual systems, with the best yielding an improvement of 13% (p = 10−6) over the best individual system and an improvement of 4% (p = 10−5) over a simple fusion of the eight systems. 相似文献

The existing secondary information services in English, French and German, pertinent to sociology, are described and their gaps and overlapping of contents are pointed out. Results of selected studies on users' needs, particularly findings on the means by which users gain access to the primary literature, are summarized. Attention is drawn to steps taken by international organizations toward expanding a data base of references to include the social sciences, for use in integrated secondary information services. Three models for such services, and important standardized elements, are outlined. 相似文献

The composition of the innovation infrastructure, as well as the most critical phases of information security at stages of the innovation cycle, is shown at the macrolevel. The foreign information systems focused on the support of innovation activities are considered. The integration of national information systems of the countries–members of the European Union into a single science and technology and innovation space is noted as a steady tendency. The most important Russian information systems focused on the support of innovation activities and the functionality of the Federal Portal on Science and Innovation and the Unified State System of accounting results of scientific research, development, and engineering works are presented. There is a lack of development of the communicative functions of information systems in scientific funds and federal scientific and technical target programs. A number of conclusions and suggestions are formulated. 相似文献

This paper explores the impact of new information technologies on the development of social communication and social systems. The properties and features of the modern information environment are analyzed. The factors and technologies of information warfare and confrontation are investigated. The role of information communication technologies in the operation of social-network movements is demonstrated. The means and methods of the mass media, social networks, and destructive network technologies that are applied to manipulate group behavior and to transform public opinion are exposed. The potential of sociodynamics as a new instrument of targeted impact on social systems is explored. Possible risks and threats that face the development of telecommunication systems and networks are assessed. Conclusions and relevant activities are formulated to prevent the rise of information confrontations and to mitigate hidden impacts and threats to the country’s social-economic, scientific, and technological development. 相似文献
