  • Application of Topic Models in the Analysis of Public Policy: A Review of the Research Status in Domestic and Foreign

    Subjects: Library Science,Information Science >> Library Science submitted time 2023-10-08 Cooperative journals: 《知识管理论坛》

    Abstract: [Purpose/significance] This paper comprehensively summarizes the application of topic models in public policy texts, which helps researchers learn from existing research results and provides theoretical and practical support for future development. [Method/process] This paper used bibliometric analysis to study from the perspectives of time trend, organization distribution, periodical distribution, etc., and summarized the application status in detail. Secondly, the LDA topic model was used to identify the main international and domestic research directions and conducted a comparative analysis. Finally, this paper summarized the problems in the application and proposed future prospects. [Result/conclusion] The application of topic models in the analysis of public policy texts is on the rise overall and has broad prospects. The starting time of domestic and foreign research is equivalent, but domestic research needs to be improved in terms of research scope, research depth, cooperation methods, and research methods. In addition, in the future development, there are problems with the applicability of the topic model’s own methods and the granularity of research content. It is necessary to further combine the characteristics of public policy texts to improve the topic model and refine research efforts.

    Subjects: Library Science,Information Science >> Library Science submitted time 2023-08-27 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] It is of great significance to improve the existing problems of technical topic analysis in patents based on the LDA, which are low recognition, weak interpretability and fuzzy boundary division,to hold the technical hot spots and track the technological frontier. [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.

  • Patent Service Design for University Library Based on Analysis of User Needs: Taking Intellectual Property Information Service Center of Shandong University of Technology as the Example

    Subjects: Library Science,Information Science >> Library Science submitted time 2023-07-26 Cooperative journals: 《图书情报工作》

    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.

  • A Study on University Patent Transfer Object Recognition Based on Multi-level Requirements Analysis——Graphene as a Case Study

    Subjects: Library Science,Information Science >> Information Science submitted time 2023-04-01 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] The identification of university patent transfer objects has positive significance for improving patent transfer conversion rate, effectively promoting the close integration of technology and economy, and achieving innovation-driven development.[Method/process] This paper used the technical requirements of enterprises to represent the market demand. Firstly, the domain multi-dimensional information technology tree was constructed based on the improved technology tree method, and then this paper analyzed the text characteristics and requirements content characteristics of the technical requirements document to determine the extraction rules and demand types based on the classification of technical requirements, and finally constructed the demand-technology matching model in different scenarios according to the demand type.[Result/conclusion] The feasibility of the method is verified by the patent data of graphene, and the results show that it is an effective means to strategically market college patents and promote patent conversion by matching the patents of colleges based on technical requirements to search for university patent operation customers.

  • A Review of Technology Opportunity Discovery from the Full Perspective of Technology Innovation

    Subjects: Library Science,Information Science >> Information Science submitted time 2023-04-01 Cooperative journals: 《图书情报工作》

    Abstract: [Purpose/significance] Technology opportunity discovery is of great significance to market competition, technology layout, regional innovation and industrial development. Clarifying the research progress in the field of technology opportunity discovery can grasp its development limitations to promote further optimization and healthy development. [Method/process] The research sorted out the relevant progress in the field from the four dimensions of technology innovation foundation, innovation environment, innovation way and innovation type based on the technology innovation full perspective and integrated the elements of technology innovation process. It also summarizes the characteristics of the technology opportunity discovery analysis unit from the perspective of technology innovation elements, and points out the existing problems and development trends of the study. [Result/conclusion] The internal attribute of technology opportunity discovery is the knowledge basis of technology innovation, and the external attribute is the technology innovation environment. Technology rebirth, technology integration, and technology breakthroughs are common ways of technology innovation. technology opportunities include three types of opportunities: emerging technologies, progressive technologies, and subversion technology. In the future, the foundation research of scientific knowledge will be strengthened, and the coordination of various resource factors will be a trend of innovation, and the methods of technology opportunity discovery will be more complex and targeted, and the process of technology opportunity discovery will be more standardized, and the results will be more credible.
