So far, there have been few descriptions on creating structures capable of storing lexicographic data, ISO 24613:2008 being one of the latest. Another one is by Spohr (2012), who designs a multifunctional lexical resource which is able to store data of different types of dictionaries in a user-oriented way. Technically, his design is based on the principle of a hierarchical XML/OWL (eXtensible Markup Language/Web Ontology Language) representation model. This article follows another route in describing a model based on entities and relations between them; MySQL (usually referred to as: Structured Query Language) describes a database system of tables containing data and definitions of relations between them. The model was developed in the context of the project "Scientific eLexicography for Africa" and the lexicographic database to be built thereof will be implemented with MySQL. The principles of the ISO model and of Spohr's model are adhered to with one major difference in the implementation strategy: we do not place the lemma in the centre of attention, but the sense description — all other elements, including the lemma, depend on the sense description. This article also describes the contained lexicographic data sets and how they have been collected from different sources. As our aim is to compile several prototypical internet dictionaries (a monolingual Northern Sotho dictionary, a bilingual learners' Xhosa–English dictionary and a bilingual Zulu–English dictionary), we describe the necessary microstructural elements for each of them and which principles we adhere to when designing different ways of accessing them. We plan to make the model and the (empty) database with all graphical user interfaces that have been developed, freely available by mid-2015.
Large classes at universities(> 1600 students) create their own challenges for teaching and learning. Audience feedback is lacking and fine tuning of lectures, courses and exam preparation to address individual needs is very difficult to achieve. At RWTH Aachen University, a course concept and a knowledge map learning tool aimed to support individual students to prepare for exams in information science through theme-based exercises were developed and evaluated. The tool was grounded in the notion of self-regul ated learning with the goal of enabling students to learn
independently.
We continue the study of the reproducibility of Propp’s annotations from Bod et al. (2012). We present four experiments in which test subjects were taught Propp’s annotation system; we conclude that Propp’s system needs a significant amount of training, but that with sufficient time investment, it can be reliably trained for simple tales.
Automatic Food Categorization from Large Unlabeled Corpora and Its Impact on Relation Extraction
(2014)
We present a weakly-supervised induction method to assign semantic information to food items. We consider two tasks of categorizations being food-type classification and the distinction of whether a food item is composite or not. The categorizations are induced by a graph-based algorithm applied on a large unlabeled domain-specific corpus. We show that the usage of a domain-specific corpus is vital. We do not only outperform a manually designed open-domain ontology but also prove the usefulness of these categorizations in relation extraction, outperforming state-of-the-art features that include syntactic information and Brown clustering.
Feminine forms of job titles raise great interest in many countries. However, it is still unknown how they shape stereotypical impressions on warmth and competence dimensions among female and male listeners. In an experiment with fictitious job titles men perceived women described with feminine job titles as significantly less warm and marginally less competent than women with masculine job titles, which led to lower willingness to employ them. No such effects were observed among women.
By way of migration, large numbers of German-speaking settlers arrived in Pennsylvania between roughly 1700 and 1750. Pennsylvania German, as a distinct variety, developed through levelling processes from L1 varieties of these migrants who came mainly from the southwestern regions of the German speaking area. Pennsylvania German is still spoken today by specific religious groups (primarily Amish and Menonnite groups) for many of whom it is an identity marker. My paper focuses on those Pennsylvania Germans who are not part of these religious groups but have the same migration history. Due to their being closer to the cultural values of American mainstream society, they were integrated into it, and during the 20th century their use of Pennsylvania German was continually diminishing. A revival of this heritage language has occurred over the past c. three decades, including language courses offered at community colleges, public libraries, etc., where ethnic Pennsylvania Germans wish to (re-)learn the language of their grandparents. Written Pennsylvania German data from four points in time between the 1860s and the 1990s were analysed in this study. Based on these linguistic analyses, differences between the data sets are shown that point towards a diachronic change in the language contact situation of Pennsylvania German speakers. Sociolinguistic and extralinguistic factors are considered that influence the role of PG and make their speakers heritage speakers much in the sense of recent immigrant heritage speakers, although delayed by 200 years.
Communication of stereotypes in the classroom: biased language use of German and Turkish adolescents
(2014)
Little is known about the linguistic transmission and maintenance of mutual stereotypes in interethnic contexts. This field study, therefore, investigated the linguistic expectancy bias (LEB) and the linguistic intergroup bias (LIB) among German and Turkish adolescents (13 to 20 years) in the school context. The LEB refers to the general phenomenon of describing stereotypes more abstractly. The LIB is the tendency to use language abstraction for in-group protective reasons. Results revealed an unmoderated LEB, whereas the LIB only occurred when foreigners were in the numerical majority, the classroom composition was perceived as a learning disadvantage, or the interethnic conflict frequency was high. These findings provide first evidence for the use of both LEB and LIB in an interethnic classroom setting.
Studies on social perception reveal that on many dimensions, smiling individuals are perceived more positively in comparison with non-smiling individuals. The experiment carried out in seven countries (China, Germany, Iran, Norway, Poland, USA, and the Republic of South Africa) showed that in some cultures, smiling individuals may be perceived less favorably than non-smiling individuals. We compared ratings of intelligence made by participants viewing photos of smiling and non-smiling people. The results showed that smiling individuals were perceived as more intelligent in Germany and in China; smiling individuals were perceived as less intelligent than the (same) non-smiling individuals in Iran. We suggest that the obtained effects can be explained by the cultural diversity within the dimension of uncertainty avoidance described in the GLOBE (Global Leadership and Organizational Behavior Effectiveness) project by House, Hanges, Javidan, Dorfman, and Gupta.
Dieser Beitrag zeigt, wie allgemeinsprachige Wörterbücher mit Angaben zur Sinn- und Sachverwandtschaft umgehen sollten, damit sie als geeignetes Hilfsmittel bei der Wortschatzarbeit sowohl im muttersprachlichen als auch im fremdsprachlichen Unterricht eingesetzt werden können. Anhand einiger Beispiele aus dem elexiko-Wörterbuch sollen Möglichkeiten aufgezeigt werden, wie kombinierte lexikalisch-semantische Informationen einen Beitrag zur gezielten Wortschatzerweiterung leisten könnten. Für eine effektive Verankerung sprachlichen und außersprachlichen Wissens sollten Erkenntnisse über das Mentale Lexikon in die Darstellung und Beschreibung von Sprache im Wörterbuch eingebunden werden. Konkrete Vorschläge illustrieren, wie Nachschlagewerke möglicherweise gestaltet werden sollten, um besser als Lehrwerke und Quellen für die Wortschatzarbeit geeignet zu sein. Dafür ist es erforderlich, dass die Dokumentation sprachlicher Zusammenhänge auf unterschiedlichen Ebenen, die angemessene Visualisierung kontextueller Phänomene und explizite Erläuterungen eine entscheidende Rolle spielen
We present a technique called event mapping that allows to project text representations into event lists, produce an event table, and derive quantitative conclusions to compare the text representations. The main application of the technique is the case where two classes of text representations have been collected in two different settings (e.g., as annotations in two different formal frameworks) and we can compare the two classes with respect to their systematic differences in the event table. We illustrate how the technique works by applying it to data collected in two experiments (one using annotations in Vladimir Propp’s framework, the other using natural language summaries).
In 2010, ISO published a standard for syntactic annotation, ISO 24615:2010 (SynAF). Back then, the document specified a comprehensive reference model for the representation of syntactic annotations, but no accompanying XML serialisation. ISO’s subcommittee on language resource management (ISO TC 37/SC 4) is working on making the SynAF serialisation ISOTiger an additional part of the standard. This contribution addresses the current state of development of ISOTiger, along with a number of open issues on which we are seeking community feedback in order to ensure that ISOTiger becomes a useful extension to the SynAF reference model.
