Abstract:
Der Beitrag beschreibt mit Blick auf die Verfügbarkeit von Online-Bildungsmedien das Zusammenspiel von Content-, Verweis- und Schulplattformen am Beispiel des Social Bookmarking-Dienstes Edutags. Als Aggregationsformen für Verweisplattformen werden redaktionelle Pflege, automatisierte Aggregation und User-generated Content angeführt, wobei letzterem besondere Bedeutung zukommt, da dadurch die tatsächliche Nutzung von Medien im Lehr-Lernkontext sichtbar gemacht wird. Damit die Möglichkeiten gemeinschaftlicher Wissensproduktion voll ausgeschöpft werden können, werden informationell offene Ökosysteme für Bildungsprozesse empfohlen.

Abstract:
With the increasing amount of user generated reference texts in the web, automatic quality assessment has become a key challenge. However, only a small amount of annotated data is available for training quality assessment systems. Wikipedia contains a large amount of texts annotated with cleanup templates which identify quality flaws. We show that the distribution of these labels is topically biased, since they cannot be applied freely to any arbitrary article. We argue that it is necessary to consider the topical restrictions of each label in order to avoid a sampling bias that results in a skewed classifier and overly optimistic evaluation results. We factor out the topic bias by extracting reliable training instances from the revision history which have a topic distribution similar to the labeled articles. This approach better reflects the situation a classifier would face in a real-life application.

Abstract:
Would you target your audience differently, knowing the real age and gender of the text authors on your website forum? This paper examines hundreds of thousands of online documents, e.g. chat lines or blog posts, showing that computers are capable to address this task better than humans, without relying on content stereotypes. Pointing out that age and gender profiling are not independent problems, we approach the task as a multiclass classification problem, combining the age and gender information to define six classes. Utilizing a wide range of stylistic and content features and a large number of readability measures we demonstrate the high predictive abilities of the parts of speech, the punctuation and the amount of emotions and slang used in the text, independently of the topic discussed.

Abstract:
We present a new bilingual FrameNet lexicon for English and German. It is created through a simple, but powerful approach to construct a FrameNet in any language using Wiktionary as an interlingual representation. Our approach is based on a sense alignment of FrameNet and Wiktionary, and subsequent translation disambiguation into the target language. We perform a detailed evaluation of the created resource and a discussion of Wiktionary as an interlingual connection for the cross-language transfer of lexical-semantic resources. The created resource is publicly available at http://www.ukp.tu-darmstadt.de/fnwkde/

Abstract (english):
We present UBY-LMF, an LMF-based model for large-scale, heterogeneous multilingual lexical-semantic resources (LSRs). UBY-LMF allows the standardization of LSRs down to a fine-grained level of lexical information by employing a large number of Data Categories from ISOCat. We evaluate UBY-LMF by converting nine LSRs in two languages to the corresponding format: the English WordNet, Wiktionary, Wikipedia, OmegaWiki, FrameNet and VerbNet and the German Wikipedia, Wiktionary and GermaNet. The resulting LSR, UBY (Gurevych et al., 2012), holds interoperable versions of all nine resources which can be queried by an easy to use public Java API. UBY-LMF covers a wide range of information types from expert-constructed and collaboratively constructed resources for English and German, also including links between different resources at the word sense level. It is designed to accommodate further resources and languages as well as automatically mined lexical-semantic knowledge.

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.
