Measuring the level of classical papers in academic journals is of great significance to journal evaluation, and there is a lack of evaluation indicators in this respect. In this paper, journal papers are divided into highly cited papers and general papers, and highly cited papers are further divided into classical papers and hot papers. The journal classical index is the proportion of citation frequency of early papers in the total citation frequency. Research on Citation Data of CSSCI Periodicals Based on Library Information and Philology and CNKI database shows: Classical Index is a New Index for Evaluating Classical Papers in Academic Journals. It is better to use the papers of 5 years ago as the basis for calculating the journal classical index. The journal classical index is not related to the influencing factors. The journal classical index is positively correlated with the H index and with lower goodness of fit. Suitable selection of classical index is needed in the evaluation of academic journals.

The library and information science has long been dedicated to designing tools for organizing and managing large amounts of knowledge information. These tools are often referred to as "Knowledge Organization System" (KOS) or "controlled structured vocabularies". Due to the long-term independent development of multiple community and business standard, a variety of different knowledge organization systems have emerged, such as subject heading systems, thesaurus, taxonomies. The thesaurus has the relations like "U", "UF", "BT", "NT"and "CT", which is organized as a network in storage. And This paper develops a method to store thesaurus in a knowledge graph structure, which also has a good effect in the data reasoning. In this paper, the main research was based on the 1990"Mechanical Engineering Thesauri" - Second Edition. By using data cleaning techniques, this paper reconstructed the traditional knowledge organization system "Mechanical Engineering Thesaurus" data into a SKOS knowledge ontology structure. By using data storage techniques, this paper stored the SKOS knowledge ontology structure in Graph database Neo4j. These knowledge organization systems make it possible to effectively organize and manage large amounts of information data.

It is analyzed whether the "University Mobile Digital Library" has provided services that meet the needs of students and teachers, and whether it has fully exerted its own value. From the perspective of user perception, this paper uses the measurement scale of LibQUAL^+TM model with library professional characteristics to explore the main factors influencing university library user satisfaction and the relationship between them by establishing the structural equation model. User expectations, perceived usefulness, and perceived service quality are all influencing factors of user satisfaction. User expectations and perceived service quality have an indirect impact on user satisfaction, and perceived usefulness has a direct impact. In addition, the indirect impact of perceived service quality on user satisfaction is almost twice the indirect impact of user expectations on user satisfaction. Users pay different attention to library systems, librarian online services, mobile devices and digital resources, but the differences are small.

In order to optimize the running strategy of sci-tech journals and improve their influence, this study analyzed the relationship between journal influence, publication delay and quantity of papers by using influence factor as the index of journal influence. The agricultural journals were taken as an example. Impact factors were normalized to eliminate the influence of natural factors of journals such as popularity of a journal on the impact factors so that the journals were comparable. Then, models were established to quantify the relationship between normalized impact factors and publication delay (or publication delay and paper load). The normalized impact factor would not affected by publication delay until the publication delay was smaller than 350 d (about 1 year) at least. The logarithm of normalized impact factor changed with logarithm of paper load and publication delay following a linear function. According to the model, the normalized impact factor decreased with increasing the paper load when the paper load was between 300 and 700, otherwise, it increased with paper load. Therefore, we suggested to shorten the publication delay within 1 year at least and adjusted the paper load according to model in order to improve the influence of journals.

The research results show that the Beijing-Tianjin-Hebei cooperation papers are mainly based on Beijing-Tianjin and Tianjin-Hebei from the perspective of the number of cooperative papers, showing significant polarization and stage characteristics. From the perspective of the density of cooperation papers, cooperative papers of Beijing are an important way of Tianjin and Hebei to publish papers, but publishing papers in cooperation with Tianjin and Hebei is only a very small part of Beijing. From the perspective of the impact of cooperative papers, the number of cited papers and impact factors of Beijing-Tianjin cooperation papers are higher than Beijing-Hebei and Tianjin-Hebei cooperation papers. From the perspective of cooperative papers, Beijing and Tianjin has a higher proportion of first author in cooperation papers than Hebei. According to the research results, the following conclusions can be drawn: the Beijing-Tianjin-Hebei science and technology collaborative innovation has achieved certain results, but it is still necessary to optimize the Beijing-Tianjin-Hebei science and technology collaborative innovation network. The full play is given to the driving role of Beijing and Tianjin in the development of science and technology innovation.

[Purpose/Significance] Digital humanities research has been developing in China for nearly ten years. It is important for further developing digital humanities research in China to clarify the differences between domestic and foreign digital humanities research.[Method/Process] Firstly, this paper compares the differences in the participation of various disciplines and cooperation modes of institutions in digital humanities research at home and abroad through quantitative statistics. Based on the existing differences, co-citation clustering, emergence detection, double-graph superposition and other functions in CiteSpace are used to introduce the research progress of digital humanities in foreign countries.[Results/Conclusions] The main difference of domestic digital humanities research lies in the low degree of participation of computer science and humanities. In international digital humanities research, there are seven groups and two research topics in computer science, and five groups and two research topics in ARTS&HUMANITIES. In addition, there is relatively little cooperation between basic subjects(computer science and information science) and humanities(ARTS&HUMANITIES OTHER TOPICS and son) in international digital humanities research, The advanced technologies in computer science are not quickly integrated into the research of humanities disciplines. It is suggested that domestic computer science and humanities should be deeply involved in the research of digital humanities, and the cooperation between basic subjects and applied subjects of digital humanities should be strengthened.

With the continuous increase in the contact rate of digital reading methods, digital reading has gradually become the mainstream reading method. College students, as a group with a higher level of education, are the main groups to receive, spread, and enjoy digital reading. They often use informal groups such as interest groups, book clubs, and fellow villagers in the digital reading process. The establishment of informal groups, the dissemination and interaction of reading content have a significant impact on the effect of digital reading. In this regard, the author uses "digital reading" as the starting point and adopts action research methods to explore the strategies for guiding the informal group development of college students in the process of digital reading from the perspective of group dynamics.
