Detecting emerging research fronts based on topological measures in citation networks of scientific publications

In this paper, we performed a comparative study in two research domains in order to develop a method of detecting emerging knowledge domains. The selected domains are research on gallium nitride (GaN) and research on complex networks, which represent recent examples of innovative research. We divided citation networks into clusters using the topological clustering method, tracked the positions ...

Can citation analysis of Web publications better detect research fronts?

We present evidence that, in some research fields, research published in journals and reported on the Web may collectively represent different evolutionary stages of the field with journals lagging a few years behind the Web on average; and that a “two-tier” scholarly communication system may therefore be evolving. We conclude that, in such fields, (a) for detecting current research fronts, aut...

Applying weighted PageRank to author citation networks

This paper aims to identify whether different weighted PageRank algorithms can be applied to author citation networks to measure the popularity and prestige of a scholar from a citation perspective. Information Retrieval (IR) was selected as a test field and data from 1956-2008 were collected from Web of Science (WOS). Weighted PageRank with citation and publication as weighted vectors were cal...

Valuing Indirect Citations in Citation Networks using Data Fusion

Any scientific activity requires awareness of previous related activities. Citation networks are the networks in which each document is compared as a link of a chain with its previous and next documents, and the documents with the highest number of citations are considered as the most effective ones in a domain. Most of the introduced methods use direct citations for valuing the documents. One ...

Extracting Keyphrases from Research Papers Using Citation Networks

Keyphrases for a document concisely describe the document using a small set of phrases. Keyphrases were previously shown to improve several document processing and retrieval tasks. In this work, we study keyphrase extraction from research papers by leveraging citation networks. We propose CiteTextRank for keyphrase extraction from research articles, a graph-based algorithm that incorporates evi...
