In this paper, a hybrid Machine Translation (MT) system is proposed by combining the result of a rule-based machine translation (RBMT) system with a statistical approach. The RBMT uses a set of linguistic rules for translation, which leads to better translation results in terms of word ordering and syntactic structure. On the other hand, SMT works better in lexical choice. Therefore, in our sys...
The characteristics of electronic states of Cd-vacancies in CdTe, an important semiconductor for various technological applications, are under debate both from theoretical and experimental points of view. Experimentally, the Cd-vacancy in its negative charge state is found to have C3v symmetry and a (-1/-2) transition level at 0.4 eV. Our first principles density functional calculations with hy...
This article introduces a quantitative, data-driven method to identify clusters of groups of data points in longitudinal data. We illustrate this method with examples from firstlanguage acquisition research. First, we discuss a variety of shortcomings of current practices in the identification and handling of stages in studies of language acquisition. Second, we explain and exemplify our method...
In this paper we present a method for the automatic term clustering. The method uses a hybrid similarity measure to cluster terms automatically extracted from a corpus by applying the C/NC value method. The measure comprises contextual, functional and lexical similarity, and it is used to instantiate the cell values in a similarity matrix. The clustering algorithm uses either the nearest neighb...
Medical Language Processing (MLP), especially in specific domains, requires fine-grained semantic lexica. We examine whether robust natural language processing tools used on a representative corpus of a domain help in building and refining a semantic categorization. We test this hypothesis with ZELLIG, a corpus analysis tool. The first clusters we obtain are consistent with a model of the domai...
The notion of expectancy grammar as a key to understanding the nature of psychologically real processes that underlie language use is introduced by Oller (1979). A central issue in this notion is that expectancy generating systems are constructed and modified in the course of language acquisition. Thus, one of the characteristics of language proficiency is that it consists of such an expectancy...
