I've just published an article over on the SAGE Ocean blog, all about Image Tagging: "In part one of this series we introduced the topic of automated image tagging and showed how Cloud Vision APIs such as Clarifai can be used to classify images into different categories. We showed examples of SAGE images and the tags assigned by different Cloud Vision APIs, then discussed use cases for this innovative technology—primarily in discoverability and accessibility. In this follow-on post, we focus on data analysis and specifically co-occurrence networks. By way of example we present a co-occurrence network derived from Clarifai image tags, which represents a kind of mental model of the SAGE journal images we processed. The following image is a visualization of the co-occurrence network that we created" You can read the full article here .
