Breaking away from traditional attempts at coreference resolution from discourseonly inputs, we try to do the same by constructing rich verb semantics from perceptual data, viz. a 2-D video. Using a bottom-up dynamic attention model and relative-motion-features between agents in the video, transitive verbs, their argument ordering etc. are learned through association with co-occurring adult commentary. This leads to learning of synonymous NP phrases as well as anaphora such as “it”,“each other” etc. This preliminary demonstration argues for a new approach to developmental NLP, with multi-modal semantics as the basis for computational language learning.
