The N 4 0 0 is an endogenous event-related brain potential (ERP) that is sensitive to semantic processes during language comprehension. The general question we address in this paper is which aspects of the comprehension process are manifest in the N 4 0 0 . The focus is on the sensitivity of the N 4 0 0 to the automatic process of lexical access, or to the controlled process of lexical integrat...

This paper presents an approach for the formal representation of components in German compounds. We assume that such a formal representation will support the segmentation and analysis of unseen compounds that feature components already seen in other compounds. An extensive language resource that explicitly codes components of compounds is GermaNet, a lexical semantic network for German. We summ...

The lexical representation of complex words in Indo-European languages is generally assumed to depend on semantic compositionality. This study investigated whether semantically compositional and noncompositional derivations are accessed via their constituent units or as whole words. In an overt visual priming experiment (300 ms stimulus onset asynchrony, SOA), event-related potentials (ERPs) we...

An essential aim in the research on semantic cognition is to understand interplay between structure of representation and controlled processes that operate it generate flexible behaviours. To evaluate link network connectivity control functions (semantic inhibition switching), we employed a theory approach revealed processing was reliably associated with conceptual representation. In particular...

Semantic similarity of text plays an important role in many NLP tasks. It requires using both local information like lexical semantics and structural information like syntactic structures. Recent progress in word representation provides good resources for lexical semantics, and advances in natural language analysis tools make it possible to efficiently generate syntactic and semantic annotation...

The idea of a Lexical knowledge base was recently proposed by the ESPRIT BRA AQUILEX [Briscoe 91], [Calzolari 92] project, to provide information, mostly of a semantic nature, internally consistently structured and electronically available. Three levels of lexical representation are proposed in AQUILEX: (a) Machine Readable Dictionary (MRD), i.e. an electronic version of the paper dictionary; (...

The Mental Lexicon (ML) refers to the organization of lexical entries of a language in the human mind.A clear knowledge of the structure of ML will help us to understand how the human brain processes language. The knowledge of semantic association among the words in ML is essential to many applications. Although, there are works on the representation of lexical entries based on their semantic a...

Abstract The N400 is an endogenous event-related brain potential (ERP) that is sensitive to semantic processes during language comprehension. The general question we address in this paper is which aspects of the comprehension process are manifest in the N400. The focus is on the sensitivity of the N400 to the automatic process of lexical access, or to the controlled process of lexical integrati...

The Resource Description Framework (RDF) provides a low-level general model to describe relationships between objects. Its ultimate goal is to permit the representation, combination and processing of most kinds of metadata or knowledge from Web-accessible documents or databases. Metadata resources can then be processed for information retrieval, filtering, personalizing, aggregation or manageme...
