Lexical Semantic Constraints on the Syntactic Realization of Semantic Role Theme

摘要

When mapped to syntactic elements, semantic roles are constrained by lexical semantic categories of words that assume the semantic roles. Based on a large-scale tagged corpus, this paper takes the semantic role "Theme" as an example and analyzes its syntactic-semantic pattern, the influence of lexical semantic category upon its mapping to syntactic elements, the collocations of the semantic categories of noun-core structures and verb-core structures. The research initially reveals the constraints of lexical semantic categories upon the mapping of the semantic role "Theme" to syntactic elements.
