We introduce the problem of explicit modeling of form relationships between words in different languages, focusing here on languages having an alphabetic writing system and affixal morphology. We present an algorithm that learns the cross-language correspondence between affixes and letter sequences. The algorithm does not assume prior knowledge of affixes in any of the languages, using only a s...

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 ...

The Minimalist Program is guided by the idea that the syntactic system of the language faculty is designed to optimally meet design specifications imposed by the interface systems. In this paper we argue that an optimal derivational system, at least from a computational point of view, is a system that generates only objects that are well-formed and satisfy conditions imposed by the interface sy...

Some reference grammars and cross-linguistic works describe all elements that are not clear-cut words as “clitics.” As a consequence of this practice, the class suggested clitics is highly heterogeneous, which reduces usefulness “clitic” label whole. In response to situation, more nuanced typology grammatical forms proposed here. The argument crucially relies on notion formal “dependence,” esse...

Arabic has a large number of affixes that can modify a stem to form words. In automatic speech recognition (ASR) this leads to a high out-of-vocabulary (OOV) rate for typical lexicon size, and hence a potential increase in WER. This is even more pronounced for dialects of Arabic where additional affixes are often introduced and the available data is typically sparse. To address this problem we ...

Derivational nouns are widely used in Sanskrit corpora and is a prevalent means of productivity in the language. Currently there exists no analyser that identifies the derivational nouns. We propose a semi supervised approach for identification of derivational nouns in Sanskrit. We not only identify the derivational words, but also link them to their corresponding source words. The novelty of o...

Compounding is a very productive process in German to form complex nouns and adjectives which represent about 7% of the words of a newspaper text. Unlike English, German compounds do not contain spaces or other word boundaries, and the automatic analysis is often ambiguous. A (non-weighted) finite-state morphological analyzer provides all potential segmentations for a compound without any filte...

Syntax-based vector spaces are used widely in lexical semantics and are more versatile than word-based spaces (Baroni and Lenci, 2010). However, they are also sparse, with resulting reliability and coverage problems. We address this problem by derivational smoothing, which uses knowledge about derivationally related words (oldish→ old) to improve semantic similarity estimates. We develop a set ...
