The New IDS Corpus Analysis Platform: Challenges and Prospects
The present article describes the first stage of the KorAP project, launched recently at the Institut für Deutsche Sprache (IDS) in Mannheim, Germany. The aim of this project is to develop an innovative corpus analysis platform to tackle the increasing demands of modern linguistic research. The platform will facilitate new linguistic findings by making it possible to manage and analyse primary data and annotations in the petabyte range, while at the same time allowing an undistorted view of the primary linguistic data, and thus fully satisfying the demands of a scientific tool. An additional important aim of the project is to make corpus data as openly accessible as possible in light of unavoidable legal restrictions, for instance through support for distributed virtual corpora, user-defined annotations and adaptable user interfaces, as well as interfaces and sandboxes for user-supplied analysis applications. We discuss our motivation for undertaking this endeavour and the challenges that face it. Next, we outline our software implementation plan and describe development to-date
Micromechanical Properties of Injection-Molded Starch–Wood Particle Composites
The micromechanical properties of injection molded starch–wood particle composites were investigated as a function of particle content and humidity conditions.
The composite materials were characterized by scanning electron microscopy and X-ray diffraction methods. The microhardness
of the composites was shown to increase notably with the concentration of the wood particles. In addition,creep behavior under the indenter and temperature dependence
were evaluated in terms of the independent contribution of the starch matrix and the wood microparticles to the hardness value. The influence of drying time on the density
and weight uptake of the injection-molded composites was highlighted. The results revealed the role of the mechanism of water evaporation, showing that the dependence of water uptake and temperature was greater for the starch–wood composites than for the pure starch sample. Experiments performed during the drying process at 70°C indicated that
the wood in the starch composites did not prevent water loss from the samples.Peer reviewe
Igel: Comparing document grammars using XQuery
Igel is a small XQuery-based web application for examining a collection of document grammars; in particular, for comparing related document grammars to get a better overview of their differences and similarities. In its initial form, Igel reads only DTDs and provides only simple lists of constructs in them (elements, attributes, notations, parameter entities). Our continuing work is aimed at making Igel provide more sophisticated and useful information about document grammars and building the application into a useful tool for the analysis (and the maintenance!) of families of related document grammar
Improvements in the CLARIN Component Metadata Infrastructure
This article reports about the on-going work on a new version of the metadata framework Component Metadata Infrastructure (CMDI), central to the CLARIN infrastructure. Version 1.2 introduces a number of important changes based on the experience gathered in the last five years of intensive use of CMDI by the digital humanities community, addressing problems encountered, but also introducing new functionality. Next to the consolidation of the structure of the model and schema sanity, new means for lifecycle management have been introduced aimed at combatting the observed proliferation of components, new mechanism for use of external vocabularies will contribute to more consistent use of controlled values and cues for tools will allow improved presentation of the metadata records to the human users. The feature set has been frozen and approved, and the infrastructure is now entering a transition phase, in which all the tools and data need to be migrated to the new version
Sustainability of annotated resources in linguistics: A web-platform for exploring, querying, and distributing linguistic corpora and other resources
N-Benzyl-5-(dimethylamino)naphthalene-1-sulfonamide
The structure of the title compound, C19H20N2O2S, displays intermolecular N—H...O hydrogen bonding, which generates inversion dimers. There is no π–π stacking in the crystal structure. The dihedral angle between the phenyl ring and naphthalene ring system is 59.16 (11)°
