Universal Conceptual Cognitive Annotation (UCCA)
Syntactic structures, by their nature, reflect first and foremost the formal constructions used for expressing meanings. This renders them sensitive to formal variation both within and across languages, and limits their value to semantic applications. We present UCCA, a novel multi-layered framework for semantic representation that aims to accommodate the semantic distinctions expressed through...
متن کاملUCCA: A Semantics-based Grammatical Annotation Scheme
Syntactic annotation is an indispensable input for many semantic NLP applications. For instance, Semantic Role Labelling algorithms almost invariably apply some form of syntactic parsing as preprocessing. The categories used for syntactic annotation in NLP generally reflect the formal patterns used to form the text. This results in complex annotation schemes, often tuned to one language or doma...
متن کاملHUME: Human UCCA-Based Evaluation of Machine Translation
Human evaluation of machine translation normally uses sentence-level measures such as relative ranking or adequacy scales. However, these provide no insight into possible errors, and do not scale well with sentence length. We argue for a semantics-based evaluation, which captures what meaning components are retained in the MT output, thus providing a more fine-grained analysis of translation qu...
متن کاملA Transition-Based Directed Acyclic Graph Parser for UCCA
We present the first parser for UCCA, a cross-linguistically applicable framework for semantic representation, which builds on extensive typological work and supports rapid annotation. UCCA poses a challenge for existing parsing techniques, as it exhibits reentrancy (resulting in DAG structures), discontinuous structures and non-terminal nodes corresponding to complex semantic units. To our kno...
متن کاملCarbon admissions
While many governments are dragging their feet on taking seriously the many aspects of climate change and how to address them, environmental and conservation groups have suddenly found an old enemy has turned into a new friend that has caught many of them by surprise. Several major supermarket companies are now embarking on policies that will see them pledging to do very much more to tackle the...
