Incremental Processing and the Hierarchical Lexicon
نویسنده
چکیده
Hierarchical lexicon structures are not only of great importance for the nonredundant representation of lexical information, they may also contribute to the efficiency of the actual processing of natural language. Two parsing techniques that render the parsing process efficient are presented. Windowing is a technique for incrementally accessing the hierarchical lexicon. Lexical preferencing implements preferences within the parsing process as a natural consequence of the hierarchical structure of the lexicon. Within a proof-theoretic approach to Categorial Grammar it is possible to implement these techniques in a formal and principled way. Special attention is paid to idiomatic expressions.

Models of EFL Learners’ Vocabulary Development: Spreading Activation vs. Hierarchical Network Model
Semantic network approaches view organization or representation of internal lexicon in the form of either spreading or hierarchical system identified, respectively, as Spreading Activation Model (SAM) and Hi- erarchical Network Model (HNM). However, the validity of either model is amongst the intact issues in the literature which can be studied through basing the instruction compatible wi...
متن کاملIncremental Construction of Millstream Configurations Using Graph Transformation
Millstream systems are a non-hierarchical model of natural language. We describe an incremental method for building Millstream configurations while reading a sentence. This method is based on a lexicon associating words and graph transformation rules.
متن کاملCorrect Readers for the Incremental Construction of Millstream Configurations by Graph Transformation
Millstream systems have been proposed as a non-hierarchical method for modelling natural language. Millstream configurations represent and connect multiple structural aspects of sentences. We present a method by which the Millstream configurations corresponding to a sentence are constructed. The construction is incremental, that is, it proceeds as the sentence is being read and is complete when...

متن کاملThe Interplay Between Lexical and Syntactic Resources in Incremental Parsebanking
Automatic syntactic analysis of a corpus requires detailed lexical and morphological information that cannot always be harvested from traditional dictionaries. In building the INESS Norwegian treebank, it is often the case that necessary lexical information is missing in the morphology or lexicon. The approach used to build the treebank is incremental parsebanking; a corpus is parsed with an ex...
