Mini Project: Bibliographic Analysis of Computing

I have been curious about tools for analysing social connections for a while.


In this post I am looking at a couple of ways to analyse bibliographic relationships. Starting with the simplest, Word Clouds but then  at an interesting tool VosViewer discussed previously. All the data is taken from the University of Northampton's Research Repository - Nectar - for members of the academic Computing team.  




Word Clouds

The image above is based on data for all the listed publications for the computing team since 2011. It includes the authors, title, conference, etc; but no abstract. It takes quite a bit of editing and really all that is being shown is the Authors name for the most published authors and a few key terms. Provides a nice snap shot but is difficult to interpret.




Co-author Analysis
Here is the same data but processed using software that is only looking at the authors and showing how many times a particular pair have published together. Some interconnections between authors can be seen.


Text Analysis
This is the same tool as above, but this time looking at the text within the title and abstracts. All words in the title and abstract of the papers; but using binary counting (so a term is only counted once per publication) and allowing only the terms with 60% highest relevance through; you can get a graph like the one below. Personally I the graph find beautiful, gives a sense of a lot going on; but is difficult to interpret.


Now repeating the same exercise but with only words that appear at least three times.

The groups are clearer. This group has some interesting subject area coming out; for example wireless networking and machine-to-machine communicaton; alongside pedagogic, cultural research and sensors for animals.


Let us apply this last approach to some individual cases
Case Study 1: Mid-Research Career Academic



Case Study 2: Mid-Research Career Academic 2


In both Case Study 1 and 2, there are several groupings. Case study 1 the subjects in the groupings are more diverse than in case study 2, which has greater specialisation.


Case Study 3: Early Career Researcher
Greater separation in the groups (though three groups are related in terms of subject) than in the first two case studies. This is in part may be due to the smaller number of papers compared to the first two case studies (between four to eight times fewer).

Case Study 4: PhD by Publication Candidate

There is a stronger inter-relationships between the groups, than has been in some of the other case studies. This, I would argue, is a positive feature for someone pursuing a PhD by publication; suggesting a coherent 'story' to their publications.

Social Analysis of Publications

The Computing staff's network of co-authors, at the University of Northampton, based on the University's  research repository NECTAR - http://nectar.northampton.ac.uk/view/divisions/SSTCT.html on 12th November 2016. The data goes back to 2010.




The data was analysed using the software VOSviewer - http://www.vosviewer.com/ free software for visualising networks. Differences in colours represents, the clusters of publications with those authors picked out by the software. The relative size of the circles is the relative number of publications listed; so for the two biggest circles/hubs it relates to 55 and 34 publications in this time period. Some relatively new authors, to the University but not to research, explains some of the 'islands' and the number of publications within it - it only reflects publications whilst at the University of Northampton.

To dig a little deeper, going to  look at the two biggest 'hubs' through their NECTAR records, so potentially going …

Computer lecturer’s research helps improve the next generation of technology

Taken from: http://www.northampton.ac.uk/news/computer-lecturers-research-helps-improve-the-next-generation-of-technology/ A computing lecturer at the University of Northampton, who is researching into how the efficiency of our everyday devices, such as mobile phones, can be improved, has been awarded the best paper at two recent conferences. Dr Michael Opoku Agyeman has written several journal papers focusing on how the next generation of technology can meet the ever increasing demands from consumers. He was invited to present his work at the 19th Euromicro Conference on Digital System Design in Cyprus and the Institute of Electrical and Electronics Engineers’ 14th International Conference in Paris. Part of his research concentrates on whether several processing elements can be incorporated on a single chip, known as System-On-Chip, to improve the efficiency and speed of the computing systems that we use every day, from mobile phones to video-game consoles and even medical equipment…
