To carry out this process, we used spaCy [9], which is a Python/Cython library for advanced natural language processing.
It offers lemmatization and is one of few high-level NLP systems to offer that functionality. docs_to_json function. Dependency parsing is one of the critical tasks in NLP. Our system must conclude that vegetarian fare, vegetarian dishes, and vegetarian food refer to the same thing, that having and serving are equivalent here, and that all these parse structures still lead to the same meaning representation. 2.6 Semantic Dependency Parsing Similar to dependency parsing, semantic depen-dency parsing (Che et al.,2012, SDP) is a task to capture the semantic structure of a sentence. Navigating the parse tree. In this series of chapters on semantic parsing, we're referring exclusively to the executable kind of meaning representation.
