Understanding the semantic structure of unstructured data -- text, dialogs, images -- is a critical challenge given their central role in many applications, including question answering, dialog systems, information retrieval... In recent years, there has been much interest in designing models and algorithms to automatically extract and manipulate these semantic representations from raw data.

Semantics is a diverse field. It encompases extracting structured data from text and dialog data (knowledge base extraction, logical form extraction, information extraction), linguistic approaches to extract and compose representation of meaning, inference and reasoning over meaning representation based on logic or algebra. It also includes approaches that aims at grounding language by learning relations between language and visual observations, linking language to the physical world (e.g. through robotics, machine commands). Despite spanning different disciplines with seemingly incompatible views, these approaches to semantics all aims at enabling computers to evolve and interact with humans and the physical world in general.

The goal of the workshop is dual. First, we aim at gathering experts from the different fields of semantics to favor cross-fertilization, discussions and constructive debates. Second, we encourage invited speakers and participants to expose their future research directions, take position and highlight the key challenges the community need to face. The workshop devotes most of the program to panel sessions about future directions.
