Does anyone know if there exists a tool to generate the trend of interest in a particular research field over time?
I am particularly interested in wearable computing. I know this field has been hot for the last few years, I would like a measure of this “hotness” using academic publications relating to this area. i.e. the number of publications related to the keyword Wearable Computing.
Is there a tool that shows the trend of publications in an particular topic similar to how Google keeps track of keywords that people searches for?
Note: I am specifically interested in technical research field, such that papers that would get published in IEEE or some computer science journals.
