Abstract (english):
We present UBY, a large-scale lexical semantic resource combining a wide range of information from expert-constructed and collaboratively constructed resources for English and German. It currently contains nine resources in two languages: English WordNet, Wiktionary, Wikipedia, FrameNet and VerbNet, German Wikipedia, Wiktionary and GermaNet, and multilingual OmegaWiki modeled according to the LMF standard. For FrameNet, VerbNet and all collaboratively constructed resources, this is done for the first time. Our LMF model captures lexical information at a fine-grained level by employing a large number of Data Categories from ISOCat and is designed to be directly extensible by new languages and resources. All resources in UBY can be accessed with an easy to use publicly available API.

Abstract:
The semi-automatic development of ontologies is an important field of research, since existing ontologies often suffer from their small size, unaffordable construction cost, and limited quality of ontology learning systems. The main objective of this chapter is to introduce Wiktionary, which is a collaborative online dictionary encoding information about words, word senses, and relations between them, as a resource for ontology construction. The authors find that a Wiktionary-based ontology can exceed the size of, for example, OpenCyc and OntoWordNet. One particular advantage of Wiktionary is its multilingual nature, which allows the construction of ontologies for different languages. Additionally, its collaborative construction approach means that novel concepts and domain-specific knowledge are quick to appear in the dictionary. For constructing their ontology OntOWiktiOnary, the authors present a two-step approach that involves (1) harvesting structured knowledge from Wiktionary and (2) ontologizing this knowledge (i.e., the formation of ontological concepts and relationships from the harvested knowledge). They evaluate their approach based on human judgments and find their new ontology to be of overall good quality. To encourage further research in this field, the authors make the final OntOWiktiOnary publicly available and suggest integrating this novel resource with the linked data cloud as well as other existing ontology projects.

Abstract (english):
With the rise of the Web 2.0, collaboratively constructed language resources are rivalling expert-built lexicons. The collaborative construction process of these resources is driven by what is called the "Wisdom of Crowds" phenomenon, which offers very promising research opportunities in the context of electronic lexicography. The vast number and broad diversity of authors yield, for instance, quickly growing and constantly updated resources. While expert-built lexicons have been extensively studied in the past, there is yet a gap in researching collaboratively constructed lexicons. We therefore provide a comprehensive description of Wiktionary - a freely available, collaborative online lexicon. We study the variety of encoded lexical, semantic, and cross-lingual knowledge of three different language editions of Wiktionary and compare the coverage of terms, lexemes, word senses, domains, and registers to multiple expert-built lexicons. We conclude our work by discussing several findings and pointing out Wiktionary's future directions and impact on lexicography.

Abstract (english):
Successful language acquisition has been hypothesized to involve the ability to integrate rapidly presented, brief acoustic cues in sensory cortex. A body of work has suggested that this ability is compromised in language-learning impairment (LLI). The present research aimed to examine sensory integration during rapid auditory processing by means of electrophysiological measures of oscillatory brain activity using data from a larger longitudinal study. Twenty-nine children with LLI and control participants with typical language development (n = 18) listened to tone doublets presented at a temporal interval that is essential for accurate speech processing (70-ms interstimulus interval). The children performed a deviant (pitch change of second tone) detection task, or listened passively. The electroencephalogram was recorded from 64 electrodes. Data were source-projected to the auditory cortices and submitted to wavelet analysis, resulting in time-frequency representations of electrocortical activity. Results show significantly reduced amplitude and phase-locking of early (45 75 ms) oscillations in the gamma-band range (29 52 Hz), specifically in the LLI group, for the second stimulus of the tone doublet. This suggests altered temporal organization of sensory oscillatory activity in LLI when processing rapid sequences.
