Morpheme combinatorics of compound words through Box Embeddings

  • Eric R Rosen ((formerly at) University of Leipzig)


In this study I probe the combinatoric properties of Japanese morphemes that participate in compounding. By representing morphemes through box embeddings (Vilnis et al., 2018; Patel et al., 2020; Li et al., 2019), a model learns preferences for one morpheme to combine with another in two-member compounds. These learned preferences are represented by the degree to which the box-hyperrectangles for two morphemes overlap in representational space. After learning, these representations are applied to test how well they encode a speaker’s knowledge of the properties of each morpheme that predict the plausibility of novel compounds in which they could occur.
