2. Publications and Citations

Total Publication

For citations, we found that papers started to get actively published after 2013, where the numbers peaked at 77 papers in 2018. As the literature of VGI is growing according to the, we are hoping to get more results in the upcoming years.

Annual Scienctific Production

Most Productive Authors

The highest number of papers was published by Linda See (IIASA, Austria) with 21 papers, followed by Alexander Zipf and Steffen Fritz with 16 and 15 respectively.

3. Top Author’s Productivity over Time

Here, we analyse the trend of authors productivity over time. I know it is brutal to analyse somebody’s academic performance based on the quantity not the quality, but this hints us how scholars are continuously working on VGI projects.

From the figure below, we can see Linda See ranked on the 1st place. She is affilliated in IIASA, Austria where she works on VGI and citizen science with international scholars mostly from Europe. Steffen Fritz looks to me as the most consistent VGI scholar amongst others. He published papers from 2009 to 2020, and he is also affilliated in IIASA, Austria.

4. Collaboration

As previously mentioned, the first figure below shows that the USA, Germany, and the UK are the highest producing countries of the world. Although the links doesn’t show the strength of collaboration, it is highly likely from the other statstics that the network between European countries is strong compared to other continents.

The next figure is the centrality and betweenness amongst published papers. We can see that Goodchild’s paper “Citizens as sensors: the world of volunteered geography” was in the centre of the graph where it got cited over 210 times in WoS (>5,000 in Google Scholar). As the term is new and created from an active researcher, it been continuously cited over years.

5. Our Next Step

I found that the bibliometrix are focusing on the networks of co-citations from the collections, but can only work on one database at a time. Each database requires different search queries and options for which the researcher can opt for, but there is less flexibility in bibliometrix.

I am currently working on ways to integrate the bibliography across databases and examine the results after removing the duplicates.
