Abstract： [Purpose/significance] Sorting out the research on the evaluation of technological innovation capabilities in patent-intensive industries will help establish and improve its evaluation system for technological innovation capabilities. [Method/process] By using the methods of literature review and online survey, the research firstly analyzed the definition and characteristics of patent-intensive industries, and then focused on the status quo of researches on the evaluation of technological innovation capabilities of patent-intensive industries from perspectives of evaluation indicators, evaluation models and empirical studies. [Result/conclusion] Combined with the research results of the existing industrial technological innovation capabilities, it is found that existing evaluation indicators’ pertinence and applicability are poor; Also, the evaluation method is too simple, only DEA method is used to measure the innovation efficiency of patent-intensive industries; Besides, most empirical data is secondary data and national economic data, also the research perspective is a little bit broad. It is suggested that future research should fully consider the characteristics of patent-intensive industries, adding more indicators that can reflect the industries’ patent strength and it’s economic contribution into the evaluation index system; actively exploring scientific, effective and comprehensive evaluation methods; utilizing and integrating the multi-source data for evaluating patent-intensive industry’s technological innovation capabilities and other patent data reflecting the quality and level of patent protection of the patent intensive industries, and based on regional and sub-industries perspectives to conduct empirical research.

Abstract： [Purpose/significance] This paper analyzes zero-cited papers in the field of environmental science from the perspective of the subject, to find the differences in the content of articles and external indicators between zero-quoted papers and high-cited papers and reveal the reason for the existence of zero-cited papers.[Method/process] Firstly, the PLDA model was used to identify topics that from 260 high-cited papers and 907 zero-cited papers in the domestic environmental sciences database from the Web of Science database. Then the relevance of the topics was found through topic similarity calculation. With the topic popularity used as an internal indicator, the time of publication and the journals used as external evaluation indicators, a comparison analysis of zero-cited papers and high-cited papers was made by combining topical of the papers with external indicators.[Result/conclusion] The experimental results show that under the same research topic, the influence of the journal is the main reason that influences the citation of the paper; under different topics, the topic is the main reason leading to zero-cited papers.

[Method/process] The international patent classification is introduced into the topic analysis in patents based on the LDA, and used as the language content of technical terms. The structure of WI (Word IPC) is trained to construct the WI-LDA model to achieve the identification and analysis of the subject of patent documents. [Result/conclusion] The case study of graphene field in Chinese patents and comparative study with traditional LDA models prove that the generalization ability of the WI-LDA model is strong, and the WI-LDA model can effectively reduce the difficulty of identification technical topic analysis in patents, increase the interpretability of topics and make the topic classification clearer.

Abstract： [Purpose/significance] The paper proposes an identification method based on the analysis of citations content. And a visual display is presented to overcome the problem of different citation emotions based on simple reference frequency measurement. [Method/process] First, it uses regular expressions to extract the content information of the text in full text. Then, it uses the TF-IDF algorithm to select the quoted emotion feature words, combines the emotional dictionary, and uses emotional analysis technology to quote emotion recognition. Finally, the use of visual tools shows the overall distribution of the reference emotion. [Result/conclusion] The method can effectively identify emotional information in the domain of anti-aging. The experimental results show that the positive citation accounts for 21% of the total citation frequency, neutral citation accounts for 78% of the total citation frequency, and negative citation accounts for only 1% of the total citation frequency. Compared with the traditional citation network, the visualization map based on citation emotion can effectively identify the distribution of different citation emotions on the overall data set.

Abstract： [Purpose/significance] The core value of university libraries is first of all to maintain a high degree of consistency between service and needs. This paper tries to study how to develop strengths and avoid weaknesses, meet needs, diversify and implement patent services in various ways for university libraries. It is of great significance for university libraries to improve their service performances and highlight their missions.[Method/process] The paper is based on the analysis of user needs and service design, taking the patent service practices in the Intellectual Property Information Service Center of Shandong University of Technology as the example. The patent service orientation, content, and mode of university libraries have been discussed from three dimensions as the patent quality education combing popularization and improvement, the patent scientific research service with choosing to do something, and the information analysis and decision support for industry-academy-research policies.[Result/conclusion] High quality to meet user needs is the focus of patent services work in university library. In order to carry out patent service effectively, the library should be guided by rational orientations, supported by professionals, focused on patent education and guaranteed by effective mechanism.

Abstract： [Purpose/significance] With the complexity of the scientific system, interdisciplinary research has become an important paradigm and inevitable trend of modern scientific innovation research. Identifying interdisciplinary relevant knowledge combination that has high cooperation potential, becomes the key to promoting interdisciplinary scientific research cooperation and innovation. [Method/process] Firstly,the paper selected target subject source literature,its interdisciplinary reference literature, and its interdisciplinary citing literature, so as to construct an interdisciplinary knowledge weak reference relational network based on keywords. Secondly, it classified the types of Knowledge Medium b, and identified the weak relational structure of the Knowledge Node a of the target discipline-Knowledge Medium b - Interdisciplinary Knowledge c. Finally, the paper defined the Knowledge Node Influence Index AI of the target discipline, the Knowledge Media Influence Index BI, the Interdisciplinary Knowledge Correlation Index CI, the Interdisciplinary Knowledge Combination a-c and Potential Cooperation Index P, to identify the interdisciplinary knowledge combination with high cooperation potential. [Result/conclusion] The papers of 9 CSSCI journals in the field of informatics from 2015 to 2019 and their interdisciplinary references and citations were selected as samples for empirical research, to verify the effectiveness and feasibility of the discovery method of interdisciplinary knowledge combination based on weak citation relationship, and to identify the interdisciplinary knowledge combination with high cooperation potential of intelligence disciplines such as "scientific research cooperation"-"knowledge flow"-"population dynamics model".
