AbstractIn this paper we describe the annotation of COMPARA, currently the largest post-edited parallel corpora which include Portuguese. We describe the motivation, the results so far, and the way the corpus is being annotated. We also provide the first grounded results about syntactical ambiguity in Portuguese. Finally, we discuss some …...

AbstractCross-language information retrieval consists in providing a query in one language and searching documents in one or different languages. These documents are ordered by the probability of being relevant to the user's request. The highest ranked document is considered to be the most likely relevant document. The LIC2M cross-language information …...

AbstractIn this paper, we describe the set-up process and an initial evaluation of a unit-selection speech synthesizer. The synthesizer is specific in that it is intended to speak with a prominent voice. As a consequence, only very limited resources were available for setting up the unit database. These resources have …...

AbstractThis paper describes results of the first successful effort in applying a stochastic strategy – or, namely, a second order Markov model paradigm implemented by the TnT trigram tagger – to morphosyntactic tagging of Croatian texts. Beside the tagger, for purposes of both training and testing, we had at our …...

AbstractAutomatic question answering (QA) is a complex task, which lies in the cross-road of Natural Language Processing, Information Retrieval and Human Computer Interaction. A typical QA system has four modules – question processing, document retrieval, answer extraction and answer presentation. In each of these modules, a multitude of tools can …...

AbstractThe proliferation of multilingual documentation in our Information Society has become a common phenomenon. This documentation is usually categorised by hand, entailing a time-consuming and arduous burden. This is particularly true in the case of keyword assignment, in which a list of keywords (descriptors) from a controlled vocabulary (thesaurus) is …...

AbstractSpoken dialogue systems are common interfaces to backend data in information retrieval domains. As more data is made available on the Web and IE technology matures, dialogue systems, whether they be speech- or text-based, will be more in demand to provide user-friendly access to this data. However, dialogue systems must …...

AbstractIn Japanese, syntactic structure of a sentence is generally represented by the relationship between phrasal units, or bunsetsus inJapanese, based on a dependency grammar. In the same way, thesyntactic structure of a sentence in a large, spontaneous, Japanese-speech corpus, the Corpus of Spontaneous Japanese (CSJ), isrepresented by dependency relationships between …...

AbstractEntities are pivotal in describing events and objects, and also very important in Document Summarization. In general only explicit entities which can be extracted by a Named Entity Recognizer are used in real applications. However, implicit entities hidden behind the phrases or words, e.g. entity referred by the phrase “cross …...

AbstractValence dictionaries are dictionaries in which logical predicates (most of the times verbs) are inventoried alongside with the semantic and syntactic information regarding the role of the arguments with which they combine, as well as the syntactic restrictions these arguments have to obey. In this article we present the incipient …...

AbstractTagging as the most crucial annotation of language resources can still be challenging when the corpus size is big and when the corpus data is not homogeneous. The Chinese Gigaword Corpus is confounded by both challenges. The corpus containsroughly 1.12 billion Chinese characters from two heterogeneous sources: respective news in …...

AbstractThis paper describes the development process of a contextualized corpus for research on Human-Robot Communication. The data have been collected in two Wizard-of-Oz user studies performedwith 22 and 5 users respectively in a scenario that is called the HomeTour. In this scenario the users show the environment (a single room, …...

AbstractThe ZT corpus (Basque Corpus of Science and Technology) is a tagged collection of specialized texts in Basque, which wants to be a main resource in research and development about written technical Basque: terminology, syntax and style. It will be the first written corpus in Basque which will be distributed …...

AbstractGeneral purpose ontologies and domain ontologies make up the infrastructure of the Semantic Web, which allow for accurate data representations with relations, and data inferences. In our approach to multimodal dialogue systems providing question answering functionality (SMARTWEB), the ontological infrastructure is essential. We aim at an integrated approach in which …...

AbstractMany learning tasks require substantial skills training. Ideally, the student might benefit the most from having a human expert – a teacher or trainer – at hand throughout, but human expertise remains a scarce resource. The second-best solution could be to do skills training with a computer-based self-training system. This …...

AbstractThe aim of this paper is to present the MORBO/COMP project, which has reached its final stage in development and will soon be published on-line. MORBO/COMP is large database of compound types in over 20 languages. The data for these languages have been collected and analysed by a group of …...

AbstractIn the present contribution we claim that corpus annotation serves, among other things, as an invaluable test for linguistic theories standing behind the annotation schemes, and as such represents an irreplaceable resource of linguistic information for the build-up of grammars. To support this claim we present four linguistic phenomena for …...

AbstractWe describe an experiment with Czech-English word alignment. Half a thousand sentences were manually annotated by two annotators in parallel and the most frequent reasons for disagreement are described. We evaluate the accuracy of GIZA++ alignment toolkit on the data and identify that lemmatization of the Czech part can reduce …...

AbstractKnowledge has been crucial for the country’s development and business intelligence, where valuable knowledge is distributed over several websites with heterogeneous formats. Moreover, finding the needed information is a complex task since there has been lack of semantic relation and organization. Even if it has been found, an overload may …...

AbstractThis paper discusses the parameterized Equivalence Class Method for Dutch, an approach developed to incorporate standard lexical representations for Dutch idioms into representations required by any specific NLP system with as minimal manual work as possible. The purpose of the paper is to give an overview of parameters applicable to …...
