Comments
This visualisation indicates (quite nicely) that Biology and Psychology have the highest Academic influence out of the subjects investigated and the metric indexes used. These conclusions are strengthened further by the parallel between the trends shown in both the JCR’s Impact Factors and the h5 Index. Such findings would be in line with the notion that scientific subjects such as Biology and Medicine are primarily experimental-based entities. Experimental methodologies are prime academic patents that require consistent and accurate citation, thereby naturally predisposing the subjects built upon these methodologies to a higher citation count.
However, it is this predisposition to higher citation counts held by some subjects over others, that limits the validity of the conclusions one can draw from this visualisation. These are standardised measures that don’t take these predispositions into account. One citation in a discipline prone to many citations (such as Biology) is worth comparatively less than one citation in a subject that is not predisposed to them (Philosophy). Citation scores have relative meanings depending on which academic context they occur in. In order for our visualisation to be more informative, it must also take this relativity into account.
One surprising find was the low representation Physics had in the world of Academia. One might assume that – given its history as a majorly influential academic subject on humankind (the atom bomb and space exploration to name but a few) it would be more influential. On the one hand, its low representation may well be due to data collection biases: failing to pick journals that were truly representative of the discipline. On the other hand, this may provide a genuine insight into the true academic prestige of Physics. Owing to the nature of Physics as a highly esoteric subject, it might be that this academic isolation is also reflected in the impact factors. Furthermore, one characteristic I noticed when researching and analysing these articles is that the majority of research in physics is of a theoretical and not an experimental nature. Without this experimental bedrock, there is less of a predisposition to cite other work, something that is firmly embedded within other science subjects.
As a final comment, although the data and the visualisation is far from a perfect representation of reality, it was certainly more objective than the linguistic datasets we compiled. Whereas we had to use our own judgement in selecting ‘technical’ words for our investigation, these citation metrics were indisputable numerical values and could therefore be reproducible – a characteristic that remained questionable for our linguistic datasets.
