The present paper addresses the question how in syntactic parsing the coverage of words in previously unseen text may be improved. The adjectives in English are presented here as a case study. Working on the assumption that most new words that are introduced into the language are constructed on the basis of already existing words through the application of word-formation processes, we investiga...

Three experiments examined the conditions under which infants acquiring English succeed in mapping novel adjectives, applied ostensively to individual objects, to other objects with the same property (color or texture). Twenty-one-month-old infants were introduced to a target (e.g., a yellow object) and asked to choose between (1) a matching test object (e.g., a different yellow object) and (2)...

The need to distinguish two syntactic sources for adnominal adjectives (a direct modification and a relative clause one), with the associated interpretive properties, turns out to have certain implications for the semantic classification of adjectives. We will see that it provides evidence for the existence of a class of truly privative adjectives, and for the conclusion that subsective adjecti...

In this paper we discuss the semantics of adjectives from the perspective of a Modern Type Theory (MTT) with an adequate subtyping mechanism. In an MTT, common nouns (CNs) can be interpreted as types and, in particular, CNs modified by intersective and subsective adjectives can be given semantics by means of Σ-types. However, an interpretation of CNs as types would not be viable without a prope...

Adjectives are one of the major contributors to conveying subjective meaning to sentences. Understanding the semantics of adjectives is essential for understanding natural language sentences. In this paper we propose a novel approach for learning different properties that an adjective can describe, corresponding to the ‘attribute concepts’, which is not currently available in existing linguisti...

In the paper we analyse Polish descriptive adjectives which occur in domain related texts. The experiments were done on data obtained from hospital discharge records. Prenominal adjectives selected from these texts were filtered out of presumably relative adjectives and clustered on the basis of a set of context related features and interword relations derived from Wordnet. We tested if this pr...

Nowadays, many daily human activities such as education, trade, talks, etc are done by using the Internet. In such things as registration on Internet web sites, hackers write programs to make automatic false registration that waste the resources of the web sites while it may also stop it from functioning. Therefore, human users should be distinguished from computer programs. To this end, this p...

Nowadays, Wordnet is used in natural language processing as one of the major linguistic resources. Having such a resource for Persian language helps researchers in computational linguistics and natural language processing fields to develop more accurate systems with higher performances. In this research, we propose a model for semi-automatic construction of Persian wordnet of verbs. Compound ve...

We use Pregroups to provide an algebraic analysis of Persian sentences. Our analysis hints to some of the profound and subtle properties of the Persian grammar, e.g. similarity of its parsing patterns to Hindi (both descendants of of Sanskrit) and similarity in parsing patterns of its causal subordinate and relative sentences. These findings are facilitated by the use of reduction diagrams, a f...

In statistical machine translation, data sparsity is a challenging problem especially for languages with rich morphology and inconsistent orthography, such as Persian. We show that orthographic preprocessing and morphological segmentation of Persian verbs in particular improves the translation quality of Persian-English by 1.9 BLEU points on a blind test set.
