Using Parallel Texts and Lexicons for Verbal Word Sense Disambiguation

We present a system for verbal Word Sense Disambiguation (WSD) that is able to exploit additional information from parallel texts and lexicons. It is an extension of our previous WSD method, which gave promising results but used only monolingual features. In the follow-up work described here, we have explored two additional ideas: using English-Czech bilingual resources (as features only - the task itself remains a monolingual WSD task), and using a 'hybrid' approach, adding features extracted both from a parallel corpus and from manually aligned bilingual valency lexicon entries, which contain subcategorization information. Albeit not all types of features proved useful, both ideas and additions have led to significant improvements for both languages explored

Comparing Czech and English AMRs

A Contrastive Lexical description of Basic Verbs. Examples from Swedish and Czech.

This paper aims at a lexical description of frequent, but not enough cognitively salient uses of frequent lexical verbs in Swedish on the background of Czech, with some implications for the lexical description of basic verbs in general. It results in a draft of a production lexicon of Swedish basic verbs for advanced Czech learners of Swedish, with focus on their uses as light verbs

Annotation, exploitation and evaluation of parallel corpora

Exchange between the translation studies and the computational linguistics communities has traditionally not been very intense. Among other things, this is reflected by the different views on parallel corpora. While computational linguistics does not always strictly pay attention to the translation direction (e.g. when translation rules are extracted from (sub)corpora which actually only consist of translations), translation studies are amongst other things concerned with exactly comparing source and target texts (e.g. to draw conclusions on interference and standardization effects). However, there has recently been more exchange between the two fields – especially when it comes to the annotation of parallel corpora. This special issue brings together the different research perspectives. Its contributions show – from both perspectives – how the communities have come to interact in recent years

Důležitá slova. Podklady ke kolokačnímu švédsko-českému slovníku základních sloves

Basic verbs, i.e. very common verbs that typically denote physical movements, locations, states or actions, undergo various semantic shifts and acquire different secondary uses. In extreme cases, the distribution of secondary uses grows so general that they are regarded as auxiliary verbs (go and to be going to), phase verbs (turn, grow), etc. ese uses are usually well-documented by grammars and language textbooks, and so are idiomatic expressions (phraseologisms) in dictionaries. ere is, however, a grey area in between, which is extremely difficult to learn for non-native speakers. is consists of secondary uses with limited collocability, in particular light verb constructions, and secondary meanings that only get activated under particular morphosyntactic conditions. e basic-verb secondary uses and constructions are usually semantically transparent, such that they do not pose understanding problems, but they are generally unpredictable and language-specific, such that they easily become an issue in non-native text production. In this thesis, Swedish basic verbs are approached from the contrastive point of view of an advanced Czech learner of Swedish. A selection of Swedish constructions with basic verbs is explored. e observations result in a proposal for the structure of a machine-readable Swedish-Czech...Základní slovesa (basic verbs), tj. frekventovaná významová slovesa, jež zpravidla popisují fyzický pohyb, umístění, stav, nebo děj, procházejí řadou sémantických posunů, díky kterým se používají k vyjádření druhotných, přenesených významů. V krajních případech se dané sloveso stává pomocným, způsobovým, nebo fázovým slovesem a přestávají pro ně platit kolokační omezení, jež se vztahují na sloveso užité v jeho primárním (tj. doslovném) významu. Tato užití sloves bývají většinou dobře dokumentována v gramatikách i učebnicích, stejně jako kvalitní slovníky podávají podrobnou informaci o užití těchto sloves v ustálených frazeologických spojeních. Mezi plně gramatikalizovaným užitím na jedné straně a idiomatickým, frazeologickým užitím na druhé straně však existuje celá škála užití základních sloves v přenesených významech, jejíž zvládnutí je pro nerodilého mluvčího značně obtížné: užití v přeneseném významu, jež mají omezenou kolokabilitu. To jsou především verbonominální konstrukce někdy nazývané analytické predikáty (light verb constructions), ale také užití, která za určitých omezených morfosyntaktických podmínek (např. pouze v negaci) aktivují abstraktní sémantické rysy u jiných predikátů, např. zesilují význam, nebo implikují, že daný děj již trvá dlouho, a podobně. Tato druhotná užití významových sloves...Institute of Germanic StudiesÚstav germánských studiíFilozofická fakultaFaculty of Art

Cross-Lingual Induction and Transfer of Verb Classes Based on Word Vector Space Specialisation

Existing approaches to automatic VerbNet-style verb classification are heavily dependent on feature engineering and therefore limited to languages with mature NLP pipelines. In this work, we propose a novel cross-lingual transfer method for inducing VerbNets for multiple languages. To the best of our knowledge, this is the first study which demonstrates how the architectures for learning word embeddings can be applied to this challenging syntactic-semantic task. Our method uses cross-lingual translation pairs to tie each of the six target languages into a bilingual vector space with English, jointly specialising the representations to encode the relational information from English VerbNet. A standard clustering algorithm is then run on top of the VerbNet-specialised representations, using vector dimensions as features for learning verb classes. Our results show that the proposed cross-lingual transfer approach sets new state-of-the-art verb classification performance across all six target languages explored in this work.Comment: EMNLP 2017 (long paper

PARSEME Survey on MWE Resources

International audienceThis paper summarizes the first results of an ongoing survey on multiword resources carried out within the IC1207 Cost ActionPARSEME (PARSing and Multi-word Expressions). Despite the availability of language resource catalogues and the inventory ofmultiword data-sets available at the SIGLEX-MWE website, multiword resources are scattered and prove to be difficult to be found.In many cases, language resources such as corpora, treebanks or lexical databases include multiwords as part of their data or take theminto consideration in their annotations. However, it is needed to centralize these resources so that other researches may subsequentlyuse them. The final aim of this survey is thus to create a portal where researchers may find multiword resources or multiword-awarelanguage resources for their research. We report on how the survey was designed and analyze the data gathered so far. We also discussthe problems we have detected upon examination of the data and possible ways of enhancing the survey
