The article intends to highlight the particularities of the derivational morphology mechanisms that will help in lexical resources extension. Some computing approaches for derivational morphology are given for several languages, inclusively for Romanian. This paper deals with some preprocessing particularities, that are needed in the process of automatic generation. Then, generative mechanisms ...

Combinatory Categorial Grammar (CCG) is generally construed as a fully lexicalized formalism, where all grammars use one and the same universal set of rules, and crosslinguistic variation is isolated in the lexicon. In this paper, we show that the weak generative capacity of this ‘pure’ form of CCG is strictly smaller than that of CCG with grammar-specific rules, and of other mildly context-sen...

In this study we investigate using an unsupervised generative learning method for subjectivity detection in text across different domains. We create an initial training set using simple lexicon information, and then evaluate a calibrated EM (expectation-maximization) method to learn from unannotated data. We evaluate this unsupervised learning approach on three different domains: movie data, ne...

In Optimality Theory a grammar consists of a ranking of constraints which are i universal and ii violable. Languages diier systematically only in their rankings of these constraints Prince and Smolensky 1993. The latter is a powerful theoretical principle which plays a central role in the explanatory scope of OT Smolensky 1996a,b, its learnability T esar and Smolensky 1996 and its consequences ...

In Optimality Theory a grammar consists of a ranking of constraints which are (i) universal and (ii) violable. Languages diier systematically only in their rankings of these constraints (Prince and Smolensky 1993). The latter is a powerful theoretical principle which plays a central role in the explanatory scope of OT (Smolensky 1996a,b), its learnability (Tesar and Smolensky 1996) and its cons...

Bilingual lexicon induction is the task of inducing word translations from monolingual corpora in two languages. In this paper we present the most comprehensive analysis of bilingual lexicon induction to date. We present experiments on a wide range of languages and data sizes. We examine translation into English from 25 foreign languages: Albanian, Azeri, Bengali, Bosnian, Bulgarian, Cebuano, G...

Horizontal redundancy is inherent to lex-ica consisting of descriptions of fully formed objects. This causes an unwelcome expansion of the lexical database and increases parsing time. To eliminate it, direct relations between descriptions of fully formed objects are often deened. These are additional to the (Typed Multiple) Inheritance Network which already structures the lexicon. Many implemen...

Complex predicates with light verbs have proven to be very challenging for syntactic theories, particularly due to the tricky distribution of valency complementations of light verbs and predicative nouns (or other predicative units) in their syntactic structure. We propose a theoretically adequate and economical representation of complex predicates with Czech light verbs based on a division of ...
