Compiling and annotating a learner corpus for a morphologically rich language: CzeSL, a corpus of non-native Czech

Learner corpora, linguistic collections documenting a language as used by learners, provide an important empirical foundation for language acquisition research and teaching practice. This book presents CzeSL, a corpus of non-native Czech, against the background of theoretical and practical issues in the current learner corpus research. Languages with rich morphology and relatively free word order, including Czech, are particularly challenging for the analysis of learner language. The authors address both the complexity of learner error annotation, describing three complementary annotation schemes, and the complexity of description of non-native Czech in terms of standard linguistic categories. The book discusses in detail practical aspects of the corpus creation: the process of collection and annotation itself, the supporting tools, the resulting data, their formats and search platforms. The chapter on use cases exemplifies the usefulness of learner corpora for teaching, language acquisition research, and computational linguistics. Any researcher developing learner corpora will surely appreciate the concluding chapter listing lessons learned and pitfalls to avoid

Term-driven E-Commerce

Die Arbeit nimmt sich der textuellen Dimension des E-Commerce an. Grundlegende Hypothese ist die textuelle Gebundenheit von Information und Transaktion im Bereich des elektronischen Handels. Überall dort, wo Produkte und Dienstleistungen angeboten, nachgefragt, wahrgenommen und bewertet werden, kommen natürlichsprachige Ausdrücke zum Einsatz. Daraus resultiert ist zum einen, wie bedeutsam es ist, die Varianz textueller Beschreibungen im E-Commerce zu erfassen, zum anderen können die umfangreichen textuellen Ressourcen, die bei E-Commerce-Interaktionen anfallen, im Hinblick auf ein besseres Verständnis natürlicher Sprache herangezogen werden

CLARIN

The book provides a comprehensive overview of the Common Language Resources and Technology Infrastructure – CLARIN – for the humanities. It covers a broad range of CLARIN language resources and services, its underlying technological infrastructure, the achievements of national consortia, and challenges that CLARIN will tackle in the future. The book is published 10 years after establishing CLARIN as an Europ. Research Infrastructure Consortium

CLARIN. The infrastructure for language resources

CLARIN, the "Common Language Resources and Technology Infrastructure", has established itself as a major player in the field of research infrastructures for the humanities. This volume provides a comprehensive overview of the organization, its members, its goals and its functioning, as well as of the tools and resources hosted by the infrastructure. The many contributors representing various fields, from computer science to law to psychology, analyse a wide range of topics, such as the technology behind the CLARIN infrastructure, the use of CLARIN resources in diverse research projects, the achievements of selected national CLARIN consortia, and the challenges that CLARIN has faced and will face in the future. The book will be published in 2022, 10 years after the establishment of CLARIN as a European Research Infrastructure Consortium by the European Commission (Decision 2012/136/EU)

A framework for the assembly and delivery of multimodal graphics in E-learning environments

In recent years educators and education institutions have embraced E-Learning environments as a method of delivering content to and communicating with their learners. Particular attention needs to be paid to the accessibility of the content that each educator provides. In relation to graphics, content providers are instructed to provide textual alternatives for each graphic using either the “alt” attribute or the “longdesc” attribute of the HTML IMG tag. This is not always suitable for graphical concepts inherent in technical topics due to the spatial nature of the information. As there is currently no suggested alternative to the use of textual descriptions in E-Learning environments, blind learners are at a significant disadvantage when attempting to learn Science, Technology, Engineering or Mathematical (STEM) subjects online. A new approach is required that will provide blind learners with the same learning capabilities enjoyed by their sighted peers in relation to graphics. Multimodal graphics combine the modalities of sound and touch in order to deliver graphical concepts to blind learners. Although they have proven successful, they can be time consuming to create and often require expertise in accessible graphic design. This thesis proposes an approach based on mainstream E-Learning techniques that can support non-experts in the assembly of multimodal graphics. The approach is known as the Multimodal Graphic Assembly and Delivery Framework (MGADF). It exploits a component based Service Oriented Architecture (SOA) to provide non experts with the ability to assemble multimodal graphics and integrate them into mainstream E-Learning environments. This thesis details the design of the system architecture, information architecture and methodologies of the MGADF. Proof of concept interfaces were implemented, based on the design, that clearly demonstrate the feasibility of the approach. The interfaces were used in an end-user evaluation that assessed the benefits of a component based approach for non-expert multimodal graphic producers
