RadioTalk is a platform that enabled citizen scientists of the Radio Galaxy Zoo (RGZ) project to provide additional descriptions of the radio subjects they were observing. This dataset contains a wealth of auxiliary information in the form of tags and comments which are especially valuable for extended radio sources. Our work is the first to explore this dataset, and for the first time, we combine text and image features to automatically classify radio galaxies using a machine learning approach. Text annotations are rare but valuable sources of information for the classification of astronomical sources.
