Abstract： [Purpose/significance] This paper has summarized disadvantages of various recognition methods of breakthrough researches by comparing and analyzing these methods. Then this study has introduced weak signals into the identification of radical innovation, focusing on various types of weak signal (especially weak ties)with a view to achieving early prediction.[Method/process] Firstly, by analyzing the existing recognition methods, this paper summarized the main problems and pointed out the necessity of weak signal research. Then, this study introduced the concept and representation of weak signal from different disciplines summarized the characteristics of weak signal and combed several methods of weak signal identification. Finally, this paper introduced the connotation and application of weak ties, and proposed that the algorithm model that integrates multiple relationships can realize the effective fusion of various weak ties and obtain more clear directional information.[Result/conclusion] In the frontier research, most attention is paid to strong ties such as reference relations between literatures and semantic relations between topic terms. However, weak ties contain more diverse information, and strengthening the analysis of them can enable early recognition of breakthrough research frontier. In the future, it is necessary to seek effective methods to capture weak ties and further dig out the evolution of the theme such as:using high-order network models to analyze weak ties to improve the accuracy of early recognition.

Abstract： [Purpose/significance] This paper explored and designed a set of China's sci-tech information multidimensional poverty index system. Moreover, it conducted an empirical research and formulated assistance measures to promote the sustainable development of poverty-stricken areas and improvement of farmers' sci-tech information literacy in these areas. And it also provided reference methods and data for China's sci-tech information poverty research. [Method/process] This paper focused on the overall goal of China's sci-tech poverty alleviation, combined with the sci-tech information needs of farmers in poverty-stricken areas, and constructed a set of farmers' sci-tech multidimensional poverty measurement index system in China with 15 indicators of 5 dimensions concluded "education" "medical" "industry" "persons" and "management", from the perspective of libraries improving farmers' sci-tech information literacy and sci-tech information capabilities in poor areas. Based on this, it used the A-F method to implement a case study in Qinba Mountains area. [Result/conclusion] The China's sci-tech information multidimensional poverty index system and measurement method based on the library's perspective proposed in this paper could effectively reflect the current situation of sci-tech information poverty in the Qinba mountains area, discovered the degree, distribution and key points of sci-tech information multidimensional poverty. Therefore it can effectively formulate the corresponding assistance measures to promote the improvement of farmers' sci-tech information literacy and the development of regional sci-tech information capabilities in Qinba mountains area.
