Found in Translation: Natural Language Understanding with Cross-lingual Grounding is an ERC funded project led by Jörg Tiedemann. It will run 2018-2023 within the language technology research group at the University of Helsinki. Stay tuned for more updates.
The success of modern intelligent systems is the ability to learn from data. The goal of the project is to develop models for natural language understanding trained on implicit information given by large collections of human translations. We will apply massively parallel data sets of over a thousand languages to acquire language-independent meaning representations that can be used for reasoning with natural languages and for multilingual neural machine translation.
Natural language understanding is the “holy grail” of computational linguistics and a long-term goal in research on artificial intelligence. Understanding human communication is difficult due to the various ambiguities in natural languages and the wide range of contextual dependencies required to resolve them. Discovering the semantics behind language input is necessary for proper interpretation in interactive tools, which requires an abstraction from language-specific forms to language-independent meaning representations.
With this project, we propose a line of research that will focus on the development of novel data-driven models that can learn such meaning representations from indirect supervision provided by human translations covering a substantial proportion of the linguistic diversity in the world. A guiding principle is cross-lingual grounding, the effect of resolving ambiguities through translation. The beauty of that idea is the use of naturally occurring data instead of artificially created resources and costly manual annotations. The framework is based on deep learning and neural machine translation and our hypothesis is that training on increasing amounts of linguistically diverse data improves the abstractions found by the model. Eventually, this will lead to language-independent meaning representations and we will test our ideas with multilingual machine translation and tasks that require semantic reasoning and inference.
