Four visual-world experiments, in which listeners heard spoken words and saw printed words, compared an optimal-perception account with the theory of phonological underspecification. This theory argues that default phonological features are not specified in the mental lexicon, leading to asymmetric lexical matching: Mismatching input (pin) activates lexical entries with underspecified coronal s...

English. The paper describes a preliminary study for the development of a novel lexicon for Italian sentiment analysis, i.e. where words are associated with polarity values. Given the influence of sentiment lexica on the performance of sentiment analysis systems, a methodology based on the detection and classification of errors in existing lexical resources is proposed and an extrinsic evaluati...

The use of lexical resources in linguistic analysis has expanded rapidly in recent years. However, most lexical resources, such as WordNet or online dictionaries, at this point do not usually indicate figurative meanings, such as conceptual metaphors, as part of a lexical entry. Studies that attempt to establish the relationships between literal and figurative language by detecting the connecti...

Although the semantic analysis and the grammatical distribution are treated as separate issues in linguistic theories, there is a close interconnection between the two in that the differences in the lexical meanings are often realized at the levels both of the grammatical function and of the lexical collocation. This is the basic assumption utilized when we design and develop Knowledge Base of ...

The purpose of this paper is to present the strategy and methodology followed at the Ixa NLP Group of the University of The Basque Country in laying the lexical foundations for language processing. Monolingual and bilingual dictionaries, text corpora, and linguists’ knowledge have been the main information sources from which lexical knowledge currently present in our NLP system has been acquire...

A puzzling observation, first noted in Austin 1956, is that the syntactic position of an adverb can affect the meaning of a sentence. (1) a. Clumsily he trod on the snail. (Austin 1956) b. He trod on the snail clumsily. (2) a. Cleverly, John dropped his cup of coffee. (Jackendoff 1972) b. John dropped his cup of coffee cleverly. (3) a. Louisa rudely departed. (McConnell-Ginet 1982) b. Louisa de...

I should like to raise some issues concerning the conversion from a traditional Marhine-Readable Dictionary (MRD) on tape to a Lexical Data Base (LDB), in order to highlight some important consequences for computational linguistics which can follow from this transition. The enormous potentialities of the information implicitly stored in a standard printed dictionary or a MRD can only be evidenc...

Semantic lexicons and lexical ontologies are some major resources in natural language processing. Developing such resources are time consuming tasks for which some automatic methods are proposed. This paper describes some methods used in semi-automatic development of FarsNet; a lexical ontology for the Persian language. FarsNet includes the Persian WordNet with more than 10000 synsets of nouns,...

This paper presents the construction of a Chinese word sense-tagged corpus. The resulting lexical resource includes mainly three components: 1) a corpus annotated with word senses; 2) a lexicon containing sense distinction and description in the feature-based formalism; 3) the linking between the sense entries in the lexicon and CCD synsets. A dynamic model is put forward to build the three kno...

Lexical resources such as WordNet and VerbNet are widely used in a multitude of NLP tasks, as are annotated corpora such as treebanks. Often, the resources are used as-is, without question or examination. This practice risks missing significant performance gains and even entire techniques. This paper addresses the importance of resource quality through the lens of a challenging NLP task: detect...
