The research data come from China's NEV cooperative invention patent applications from 2001 to 2019. This paper uses the exponential random graph model (ERGM) to study the impact of different dimensions of social capital on the NEV industry-university-research (I-U-R) innovation network. The results show that from the perspective of structural capital, the closed network structure has a positive impact on the formation of NEV I-U-R innovation network. From the perspective of cognitive capital, the homogeneity of knowledge base has a positive effect on the formation of the NEV I-U-R innovation network, and the innovation subjects with the same knowledge base breadth and the same knowledge base depth are more inclined to form a cooperative relationship. For relational capital, institutional environment similarity and organizational structure similarity are important factors affecting the formation of NEV I-U-R innovation network to a similar extent.

Despite its importance in technology innovation and evolution, few studies have explored the general pattern of the cross-domain search process leading to technology fusion. This paper proposes that the stretching between distinct technology domains could be viewed as searching in a two-dimensional knowledge partition landscape and then empirically validates the model based on a large patent dataset derived from the U.S. Patent and Trade Office (USPTO). The findings show that the general pattern of the search processes leading to technology fusion could be viewed as searching across a broad technology scope to identify limited valuable linking points within existing technology domains, and the search processes are mainly “divergent”; that is, innovative agents gradually extend the search scope to pursue new hybrid technologies. However, the cross-domain search would be more targeted if the two technology domains were closer to each other. In addition, compared to searching across a broader technology scope, digging in certain technology areas is more important for the generation of new high-impact hybrid technologies. This study provides a novel perspective for understanding the new knowledge creation process and technology fusion.</p>","PeriodicalId":21755,"journal":{"name":"Scientometrics","volume":"130 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141169964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with the growing number of publications and researchers, it becomes increasingly challenging to identify suitable collaborators. Academic collaborator recommendation is a promising solution to this problem. Traditional recommendation methods based on collaborative filtering suffer serious data sparsity. In recent years, network topology-based methods have shown good recommendation performance while alleviating the data sparsity issue to some extent by exploiting the relationships between nodes and their attributes. Nevertheless, these methods are typically based on homogeneous collaboration networks that consist only of scholar nodes and collaboration relationships, leading to suboptimal performance. In reality, collaboration involves many different types of nodes and relations that accumulate multiplex information. To address this issue, we construct a heterogeneous academic information network comprising four types of nodes: scholars, papers, organizations, and publication venues. An academic collaborator recommendation model is designed to capture multi-type attribute features and network topology features of nodes through metapaths based on the network. Specifically, the attribute features of nodes are embedded by a node type-aware embedding method. The topology features are then extracted through the node type-aware aggregation and metapath instance aggregation procedure. After that, we utilize a metapath aggregation method to gather different types of metapaths, each representing a factor that affects collaboration. Thus, the topology information and attribute information are preserved, while encompassing multi-type factors of collaboration. Finally, we compute the vector similarity to determine collaborators. Through rigorous experimentation on a large-scale interdisciplinary academic dataset, we found that the proposed model exhibits outstanding performance in practical applications. Unlike traditional approaches confined to homogeneous collaboration networks, our model delves deeper by mining and leveraging diverse node attributes and multiple collaboration influencing factors. This approach significantly enhances the accuracy and effectiveness of collaborator recommendations. Ultimately, we aspire to contribute to a more efficient and accessible platform that simplifies the search for suitable collaborators.</p>","PeriodicalId":21755,"journal":{"name":"Scientometrics","volume":"19 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141170096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By constructing patent citation networks, scholars have proposed various centrality algorithms (such as citation count, PageRank, LeaderRank, etc.) for evaluating the quality and influence of patents. However, these centrality algorithms suffer from age bias, which means these algorithms are more inclined to obtain higher rankings for older patents, thus losing fairness to younger patents. Additionally, the selection of algorithm performance evaluation indicators is crucial. If the indicators are not chosen appropriately, the results may be affected. Therefore, based on the background of Chinese green patents, this paper develops an unbiased evaluation ranking algorithm to identify significant Chinese green patents earlier.

We present a framework for scientific experience acquisition that outlines the dual dimensions of experience accumulation: self-accumulation and accumulation under senior expert guidance. To validate the framework, we conducted a case study using 2,957,700 papers from all 568 Chinese humanities and social science journals, taking into account the limitations of the international journal system. Our findings reveal that self-accumulation has been gradually declining, decreasing from 57.67% in 1980 to 4.55% in 2020. Conversely, accumulation under senior expert guidance has been steadily increasing, rising from 5.7% in 1980 to 28.69% in 2020. Furthermore, the proportion of the two approaches varies by discipline. Social sciences such as Psychology, Economics, and Management, which rely more on large teams and collaborative research, have a higher proportion of accumulation under senior expert guidance than humanities disciplines like Art, History, and Philosophy, which depend more on individual research. Finally, this research also offers a distinctive exploration of the question posed by the US National Science and Technology Council (2008): how and why do communities of innovation form and evolve.</p>","PeriodicalId":21755,"journal":{"name":"Scientometrics","volume":"50 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141060338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Academic big data will provide an important data source for more comprehensive and accurate modeling scholars due to the coexistence environment of various academic entities. Based on academic big data, an end-to-end model HCSP was proposed for predicting collaborative relationships among scholars. HCSP models scholars from two aspects: content-based features and structure-based features, and calculate the similarity between scholars based on this to predict whether there will be academic collaboration between scholars. When learning the content-based features of scholars, HCSP utilizes LSTM and multi-head attention mechanism to extract the overall and recent research interests of scholars, to capture the diversity of scholars’ research interests. When learning the structure-based features of scholars, HCSP adopts a subgraph sampling strategy based on meta paths to model the structural features of scholar nodes in heterogeneous academic network. By integrating scholars’ content-based and structure-based features, HCSP calculates the similarity between scholars to determine whether there will be a collaborative relationship between them. The experimental results indicate that the HCSP model achieves better prediction performance compared to the baseline models. It can be seen that integrating scholars’ content-based and structure-based characteristics can indeed provide a richer and more effective modeling basis for predicting their academic collaborative relationships.</p>","PeriodicalId":21755,"journal":{"name":"Scientometrics","volume":"121 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141060558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper first describes how examiner experience is related to the rate of patent allowance and repeated use of prior citations by the same examiner. Next, this paper analyzes how examiner experience is related to the extent of receiving spillover at the USPTO and the JPO. This paper uses an empirical methodology to identify examination spillovers from the European Patent Office (EPO) search result to the United States Patent and Trademark Office (USPTO) and also to the Japan Patent Office (JPO) in the sense that patent citations for rejection of a patent application tend to be “adopted” at a later office after the EPO issues search reports.
