In-text citation’s frequencies-based recommendations of relevant research papers

Abstract

From the past half of a century, identification of the relevant documents is deemed an active area of research due to the rapid increase of data on the web. The traditional models to retrieve relevant documents are based on bibliographic information such as Bibliographic coupling, Co-citations, and Direct citations. However, in the recent past, the scientific community has started to employ textual features to improve existing models’ accuracy. In our previous study, we found that analysis of citations at a deep level (i.e., content level) can play a paramount role in finding more relevant documents than surface level (i.e., just bibliography details). We found that cited and citing papers have a high degree of relevancy when in-text citations frequency of the cited paper is more than five times in the citing paper’s text. This paper is an extension of our previous study in terms of its evaluation of a comprehensive dataset. Moreover, the study results are also compared with other state-of-the-art approaches i.e., content, metadata, and bibliography. For evaluation, a user study is conducted on selected papers from 1,200 documents (comprise about 16,000 references) of an online journal, Journal of Computer Science (J.UCS). The evaluation results indicate that in-text citation frequency has attained higher precision in finding relevant papers than other state-of-the-art techniques such as content, bibliographic coupling, and metadata-based techniques. The use of in-text citation may help in enhancing the quality of existing information systems and digital libraries. Further, more sophisticated measure may be redefined be considering the use of in-text citations.

Scientific paper recommendation systems: a literature review of recent publications

“…The most common venues for publications were the ones depicted in Table 1 . Some papers [ 74 – 76 , 93 , 94 ] described the same approach without modification or extension of the actual paper recommendation methodology, e.g. by providing evaluations 8 .…”

“…We found nine papers incorporating a crawling step as part of their approach. PDFs are oftentimes collected from CiteSeer [ 38 , 46 ] or CiteSeerX [ 2 , 93 , 94 ], in some cases [ 39 , 88 , 110 ] the sources are not explicitly mentioned. Fewer used data sources are Wikipedia for articles explaining the top words from papers [ 98 ] or papers from ACM, IEEE and EI [ 109 ].…”

“…Fewer used data sources are Wikipedia for articles explaining the top words from papers [ 98 ] or papers from ACM, IEEE and EI [ 109 ]. Some approaches explicitly mention the extraction of citation information [ 2 , 38 , 39 , 46 , 88 , 93 , 94 ] e.g. to identify co-citations.…”

“…They crawl papers from CiteSeerX to retrieve the top 500 citing papers. In a follow-up work with a partially different research group Shahid et al [ 93 ] evaluate the previously presented approach with a user study.…”

“…To the best of our knowledge the literature reviews by Bai et al [9], Li and Zou [58] and Shahid et al [92] are the most recent ones targeting the domain of scientific paper recommendation systems. They were accepted for publication or published in 2019 so they only consider paper recommendation systems up until 2019 at most.…”
