An Alternative Approach to Tagging

摘要

NooJ is a linguistic development environment that allows users to construct large formalised dictionaries and grammars and use these resources to build robust NLP applications. NooJ’s approach to the formalisation of natural languages is bottom-up: linguists start by formalising basic phenomena such as spelling and morphology, and then formalise higher and higher linguistic levels, moving up towards the sentence level. NooJ provides parsers that operate in cascade at each individual level of the formalisation: tokenizers, morphological analysers, simple and compound terms indexers, disambiguation tools, syntactic parsers, named entities annotators and semantic analysers. This architecture requires NooJ’s parsers to communicate via a Text Annotation Structure that stores both correct results and erroneous hypotheses (to be deleted later).
