I found this website that does interesting visualization on country specific co-citation network maps [1].

On the most basic level, it tells which areas of research in the Philippines frequently collaborate. The data used by SCImago, the developer of the platform, came from the  Scopus® database.

As any of the post in the Filler series,  these graphs maybe of  general interest to the Philippine science community but whose importance are relative.

Some notes:

1.  Field/category size is depicted by the node size.  Medicine is bigger in terms of the number of papers published in figure 1.

2. The line (I suppose) gives the strength of connection. Medicine strongly connects with Biotechnology, Genetics, and Molecular Biology.

3. The data always came from 2 year periods.

What is interesting is the disjunt between seemingly related fields such as Physics and Engineer or Decision Science and Economics and Econometrics.

Also interesting to look at is how the connections evolve.

Since I am lazy and I have no time to tinker with it more,  I will just show you the oldest that the website can give. It is from the 2002-2003 data.

Generally, the areas relatively got larger in 2010 than in 2003. This is obvious.

The Engineering was a stronger node in the period of 2002-2003 compared to 2009-2010.

Energy research is connected to Engineering in 2003.  But in 2010, it shifted its connection to Environmental Science. There is probably a shift in focus of the research.

Physics which was more connected in 2003 became less in 2010 with only the connection in Materials Engineering left. Mathematics which was connected to Physics became more connected to Computer Science.
