My h-index as of June 2017: Coverage of researcher profile sites

Posted on Updated on

The coverage of different researcher profile sites and their citation statistics varies. Google Scholar seems to be the site with the largest coverage, – it even crawls and indexes my slides. The open Wikidata is far from there, but may be the only one with machine-readable free access and advanced search.

Below is the citation statistics in the form of the h-index from five different services.

h Service
28 Google Scholar
27 ResearchGate
22 Scopus
22(?) Semantic Scholar
18 Web of Science
8 Wikidata

Semantic Scholar does not give an overview of the citation statistics, and the count is somewhat hidden on the individual article pages. I attempted as best as I could to determine the value, but it might be incorrect.

I made a similar statistics on 8 May 2017 and reported it on the slides Wikicite (page 42). During the one and a half month since that count, the statistics for Scopus has change from 20 to 22.

Semantic Scholar is run by the Allen Institute for Artificial Intelligence, a non-profit research institute, so they may be interested in opening up their data for search. An API does, to my knowledge, not (yet?) exist, but they have a gentle robots.txt. It is also possible to download the full Semantic Scholar corpus from http://labs.semanticscholar.org/corpus/. (Thanks to Vladimir Alexiev for bringing my attention to this corpus).
