Research on Compositional Diestributional Semantics Modeling with Machine Learning. As in distributional semantics, we represent some content words (such as nouns) by vectors recording their corpus contexts. Implementing ideas from formal semantics, functional elements (such as determiners) are represented by functions mapping from expressions of one type onto composite expressions of thesame or other types. These composition functions are induced from corpus data by statistical learning of… Show more Research on Compositional Diestributional Semantics Modeling with Machine Learning. As in distributional semantics, we represent some content words (such as nouns) by vectors recording their corpus contexts. Implementing ideas from formal semantics, functional elements (such as determiners) are represented by functions mapping from expressions of one type onto composite expressions of thesame or other types. These composition functions are induced from corpus data by statistical learning of mappings from observed context vectors of input arguments to observed context vectors of composite structures. We model a number of compositional processes in this way, developing a coherent fragment of the semantics of English in a large-scale data-driven fashion. Show less
