More knowledge about Open Access (OA) scholarly publishing on the web would be helpful for citation data mining and the development of Web-based citation indexes. In the current study, five characteristics of 545 OA citing sources targeting OA research articles in four science and four social science disciplines were manually identified, including file format, hyperlinking, Internet domain, lan...

The U.S. patents network is a network of almost 3.8 millions patents (network vertices) from the year 1963 to 1999 (Hall et al. (2001)) and more than 16.5 millions citations (network arcs). It is an example of a very large citation network. We analyzed the U.S. patents network with the tools of network analysis in order to get insight into the structure of the network as an initial step to the ...

Many networks are worked with and viewed as static objects while this often isn’t the case. Oftentimes, they change over time as new nodes are added and connections are made. One such class of networks that evolve over time are citation networks, networks that show how different authors or papers reference each other. As new papers are published and added to the network, the structure and impor...

Topological properties of "scale-free" networks are investigated by determining their spectral dimensions d(S), which reflect a diffusion process in the corresponding graphs. Data bases for citation networks and metabolic networks together with simulation results from the growing network model [A.-L. Barabasi and R. Albert, Science 286, 509 (1999)] are probed. For completeness and comparisons l...

Citation networks have fed numerous works in scientific evaluation, science mapping (and more recently largescale network studies) for decades. The variety of citation behavior across scientific fields is both a research topic in sociology of science, and a problem in scientific evaluation. Normalization, tantamount to a particular weighting of links in the citation network, is necessary for al...

In addition to science citation indicators of journals like impact and immediacy, social network analysis provides a set of centrality measures like degree, betweenness, and closeness centrality. These measures are first analyzed for the entire set of 7,379 journals included in the Journal Citation Reports of the Science Citation Index and the Social Sciences Citation Index 2004, and then also ...

This study uses bibliographic coupling to identify missing relevant patent links, in order to construct a comprehensive citation network. Missing citation links can be added by taking the missing relevant patent links into account. The Pareto principle is used to determine the threshold of bibliographic coupling strength, in order to identify the missing relevant patent links. Comparisons betwe...

We introduce and solve a model which considers two coupled networks growing simultaneously. The dynamics of the networks is governed by the new arrival of network elements (nodes) making preferential attachments to pre-existing nodes in both networks. The model segregates the links in the networks as intra-links, cross-links and mix-links. The corresponding degree distributions of these links a...

The literature on social networks has explored a large number of classes of human networks e.g., citation networks, online social networks, co-authorship networks, event networks, co-location networks, genealogy networks etc. The coverage of networks in the literature is however not uniform, one such neglected area is narrative networks. These networks constitute a class of networks which are f...

Assessing the influence of a scholar’s work is an important task for funding organizations, academic departments, and researchers. Common methods, such as measures of citation counts, can ignore much of the nuance and multidimensionality of scholarly influence. We present an approach for generating dynamic visualizations of scholars’ careers. This approach uses an animated node-link diagram sho...
