Document retrieval in languages with a rich and complex morphology – particularly in terms of derivation and (single-word) composition – suffers from serious performance degradation with the stemming-only query-term-totext-word matching paradigm. We propose an alternative approach in which morphologically complex word forms are segmented into relevant subwords (such as stems, prefixes, suffixes...

We present a morphological analyser for German inflection and word formation implemented in finite state technology. Unlike purely lexicon-based approaches, it can account for productive word formation like derivation and composition. The implementation is based on the Stuttgart Finite State Transducer Tools (SFST-Tools), a non-commercial FST platform. It is fast and achieves a high coverage.

We develop a similarity measure to detect repeatedly occurring Out-of-Vocabulary words (OOV), since these carry important information. Sub-word sequences in the recognition output from a hybrid word/sub-word recognizer are taken as detected OOVs and are aligned to each other with the help of an alignment error model. This model is able to deal with partial OOV detections and tries to reveal mor...

let a be a unital r-algebra and m be a unital a-bimodule. it is shown that every jordan derivation of the trivial extension of a by m, under some conditions, is the sum of a derivation and an antiderivation.

Machine Transliteration is to transcribe a word written in a script with approximate phonetic equivalence in another language. It is useful for machine translation, cross-lingual information retrieval, multilingual text and speech processing. Punjabi Machine Transliteration (PMT) is a special case of machine transliteration and is a process of converting a word from Shahmukhi (based on Arabic s...

This paper describes a learning-based approach for automatic derivation of word variant forms by the suffixation process. We employ the sequence labeling technique, which entails learning when to preserve, delete, substitute, or add a letter to form a new word from a given word. The features used by the learner are based on characters, phonetics, and hyphenation positions of the given word. To ...

The paper presents a corpus-based comparative study of denominal adjectives in Dutch, German, and English. It aims at clarifying the notion approximation. More specifically, it focuses on investigating relation between approximation comparison as semantic categories word-formation. Drawing equivalent patterns, we both approximative readings various word-formation patterns (derivation compoundin...
