Studies in linguistics define lexico-syntactic patterns to characterize the linguistic utterances that can be interpreted with semantic relations. Because patterns are assumed to reflect linguistic regularities that have a stable interpretation, several software implement such patterns to extract semantic relations from text. Nevertheless, a thorough analysis of pattern occurrences in various c...

This study was motivated by the researchers’ goal to unfold the quality of the English translations of Persian tourism industry texts and discover the most frequent error patterns the Iranian non-native translators have committed in such texts. Thus, the following research questions were addressed: 1) Are the English versions of Persian tourist guidebooks and multimedia compact discs provided b...

Pattern recognition methods can be divided into four di erent categories: statistical or probabilistic, structural, possibilistic or fuzzy, and neural methods. A formal analysis shows that there is a computational complexity versus representational power trade-o between probabilistic and possibilistic or fuzzy set measures, in general. Furthermore, sigmoidal theory shows that fuzzy set membersh...

A methodology for classifying syntactic patterns is proposed in this paper that performs a branch and bound search over a set of prototypes. The prototypes are first clustered hierarchically and the search is performed over the hierarchy. The proposed technique is applied to a pattern recognition system where images are described by the sequence of features extracted from the chain codes of the...

Encapsulation is a major concept in object-oriented designs as design pattern catalogues, approaches for alias control, and the need for modular correctness of components demonstrate. The way encapsulation can be formally specified in existing approaches has several shortcomings. We show how encapsulation in sequential Java programs is specified by means of a new concept, called encapsulation p...

This paper presents an optimal architecture for hardware implementation of Context-Free Grammar (CFG) parsers, which can be used to accelerate the performance of applications where response to real time signal processing is a crucial aspect, such as Electrocardiogram (ECG) analysis. Our architecture increases the performance by a factor of approximately two orders of magnitude compared to the p...

Recent findings from English and Russian have shown that grammatical category plays a key role in stress assignment. In these languages, some grammatical categories have a typical stress pattern and this information is used by readers. However, whether readers are sensitive to smaller distributional differences and other morpho-syntactic properties (e.g., gender, number, person) remains unclear...

Syntactic trees, or phrase markers, have originally been suggested as a representation of syntax in the mind based on purely linguistic grounds. In this paper, the psychological reality of syntactic trees and hierarchical ordering is explored from another perspective--that of the neuropsychology of language breakdown. The study reported here examined several syntactic domains that rely on diffe...

In this paper we address the problem of automatically constructing structured knowledge from plain texts. In particular, we present a supervised learning technique to first identify definitions in text data, while then finding hypernym relations within them making use of extracted syntactic structures. Instead of using pattern matching methods that rely on lexico-syntactic patterns, we propose ...

We explored the impact of a degraded semantic system on lexical, morphological and syntactic complexity in language production. We analysed transcripts from connected speech samples from eight patients with semantic dementia (SD) and eight age-matched healthy speakers. The frequency distributions of nouns and verbs were compared for hand-scored data and data extracted using text-analysis softwa...
