Welcome to the UCCA-App wiki!

UCCA-App is an open-source, flexible web-application for syntactic and semantic phrase-based annotation in general, and for UCCA annotation in particular. UCCAApp supports a variety of formal properties that have proven useful for syntactic and semantic representation, such as discontiguous phrases, multiple parents and empty elements, making it useful to a variety of other annotation schemes with similar formal properties. UCCAApp’s user interface is intuitive and simple, so as to support annotation by users with no background in linguistics or formal representation. Indeed, a pilot version of the application has been successfully used in the compilation of the UCCA Wikipedia treebank by annotators with no previous linguistic training.

UCCA (Universal Conceptual Cognitive Annotation) is a cross-linguistically applicable semantic representation scheme, building on the Basic Linguistic Theory typological framework and Cognitive Linguistics literature. It has demonstrated applicability to multiple languages, including English, French, German and Czech, support for rapid annotation, accessibility to non-expert annotators and stability under translation. The scheme has recently proven useful for machine translation evaluation.
