Potential Issues with Google Scholar Citations

07 Aug

I have blogged recently about my experiences with Google Scholar Citations. (1,2). It has been useful in highlighting what science I have published that people might find interest as well as trends in citation patterns. It has also highlighted some potential issues in the data.

My Top Citations on Google Scholar Citations

I must admit I was quite surprised to see that the top cited paper was one from Eastman Kodak company where we looked at interactions between Sodium Dodecyl sulfate and gelatin, followed by work I did at the University of Ottawa. This work was in 1994 and 1991 respectively. This work was almost 20 years ago so it does make sense that the aggregation of citations over the years might have reached those levels. However, I would have expected that my work in the areas of NMR prediction, Computer-Assisted Structure Elucidation (CASE) and Indirect Covariance would have garnered a lot more citations, but that work did come about 10 years later. It is good to see that the more recent papers, for example that from 2008 on internet-based tools for communication and collaboration in chemistry, has garnered a following.

My papers that supposedly have no citations

Above is shown a list of my papers from as far back as 1990 that appear to not have any citations. There are also a lot of recent papers listed that I KNOW are cited, multiple times, as they have been referred to in some of my own publications. For example, the second one in the list, from 2009, entitled “Computer-assisted methods for molecular structure elucidation: realizing a spectroscopist’s dream” is an Open Access article and according to the journal statistics it is the top read article of all time on the Journal of Cheminformatics as shown here with, as of this writing, 10770 accesses. In fact, if I search the article directly on Google Scholar I find it IS cited 7 times as shown below.

 

The JChemInf Paper on Google Scholar shows 7 Citations

I don’t know why it shows up as cited in Google Scholar but not in Google Scholar Citations. However, the same issue exists for the paper on the Spectral game. See below. Shows no citations on Google Schoalr Citations but shows 7 on Google Scholar.

CItations for the Spectral Game Paper

Notice that in BOTH cases the article is listed as the Journal of Cheminformatics, not as the title of the paper. Maybe THIS is the reason the citations are missed. Maybe the publisher for the Journal of Cheminformatics is not exposed in a manner that has the publications indexed properly? Maybe….

 

 

 

About tony

Antony (Tony) J. Williams received his BSc in 1985 from the University of Liverpool (UK) and PhD in 1988 from the University of London (UK). His PhD research interests were in studying the effects of high pressure on molecular motions within lubricant related systems using Nuclear Magnetic Resonance. He moved to Ottawa, Canada to work for the National Research Council performing fundamental research on the electron paramagnetic resonance of radicals trapped in single crystals. Following his postdoctoral position he became the NMR Facility Manager for Ottawa University. Tony joined the Eastman Kodak Company in Rochester, New York as their NMR Technology Leader. He led the laboratory to develop quality control across multiple spectroscopy labs and helped establish walk-up laboratories providing NMR, LC-MS and other forms of spectroscopy to hundreds of chemists across multiple sites. This included the delivery of spectroscopic data to the desktop, automated processing and his initial interests in computer-assisted structure elucidation (CASE) systems. He also worked with a team to develop the worlds’ first web-based LIMS system, WIMS, capable of allowing chemical structure searching and spectral display. With his developing cheminformatic skills and passion for data management he left corporate America to join a small start-up company working out of Toronto, Canada. He joined ACD/Labs as their NMR Product Manager and various roles, including Chief Science Officer, during his 10 years with the company. His responsibilities included managing over 50 products at one time prior to developing a product management team, managing sales, marketing, technical support and technical services. ACD/Labs was one of Canada’s Fast 50 Tech Companies, and Forbes Fast 500 companies in 2001. His primary passions during his tenure with ACD/Labs was the continued adoption of web-based technologies and developing automated structure verification and elucidation platforms. While at ACD/Labs he suggested the possibility of developing a public resource for chemists attempting to integrate internet available chemical data. He finally pursued this vision with some close friends as a hobby project in the evenings and the result was the ChemSpider database (www.chemspider.com). Even while running out of a basement on hand built servers the website developed a large community following that eventually culminated in the acquisition of the website by the Royal Society of Chemistry (RSC) based in Cambridge, United Kingdom. Tony joined the organization, together with some of the other ChemSpider team, and became their Vice President of Strategic Development. At RSC he continued to develop cheminformatics tools, specifically ChemSpider, and was the technical lead for the chemistry aspects of the Open PHACTS project (http://www.openphacts.org), a project focused on the delivery of open data, open source and open systems to support the pharmaceutical sciences. He was also the technical lead for the UK National Chemical Database Service (http://cds.rsc.org/) and the RSC lead for the PharmaSea project (http://www.pharma-sea.eu/) attempting to identify novel natural products from the ocean. He left RSC in 2015 to become a Computational Chemist in the National Center of Computational Toxicology at the Environmental Protection Agency where he is bringing his skills to bear working with a team on the delivery of a new software architecture for the management and delivery of data, algorithms and visualization tools. The “Chemistry Dashboard” was released on April 1st, no fooling, at https://comptox.epa.gov, and provides access to over 700,000 chemicals, experimental and predicted properties and a developing link network to support the environmental sciences. Tony remains passionate about computer-assisted structure elucidation and verification approaches and continues to publish in this area. He is also passionate about teaching scientists to benefit from the developing array of social networking tools for scientists and is known as the ChemConnector on the networks. Over the years he has had adjunct roles at a number of institutions and presently enjoys working with scientists at both UNC Chapel Hill and NC State University. He is widely published with over 200 papers and book chapters and was the recipient of the Jim Gray Award for eScience in 2012. In 2016 he was awarded the North Carolina ACS Distinguished Speaker Award.

One Response to Potential Issues with Google Scholar Citations

    What happened after you corrected the title?

    Our “Towards interoperable and reproducible QSAR analyses” paper:

    http://www.jcheminf.com/content/2/1/5

    … does show citations:

    http://scholar.google.se/citations?view_op=view_citation&hl=en&user=u8SjMZ0AAAAJ&citation_for_view=u8SjMZ0AAAAJ:WF5omc3nYNoC

    Maybe the “‘” in the title is confusing the indexing system…?

    Of course, Web-of-Science is useless here as comparison, as they are not indexing the journal yet.
