Unified Dynamic Annotation Visualizer

UDAV is designed to enable different disciplines to display their automatic pre-processing results in a schema-based and reproducible, dynamic and interactive way without the need to hard-code manual and user-defined visualizations for each new project.

  abstract  = {The automatic and manual annotation of unstructured corpora is
               a daily task in various scientific fields, which is supported
               by a variety of existing software solutions. Despite this variety,
               there are currently only limited solutions for visualizing annotations,
               especially with regard to dynamic generation and interaction.
               To bridge this gap and to visualize and provide annotated corpora
               based on user-, project- or corpus-specific aspects, Unified Dynamic
               Annotation Visualizer (UDAV) was developed. UDAV is designed as
               a web-based solution that implements a number of essential features
               which comparable tools do not support to enable a customizable
               and extensible toolbox for interacting with annotations, allowing
               the integration into existing big data frameworks.},
