This workshop is a joint event of two active communities in the area of interaction paradigms to Linked Data: NLIWOD4 and QALD-9. NLIWOD, a workshop for discussions on the advancement of natural language interfaces to the Web of Data, has been organized three-times within ISWC, with a focus on soliciting discussions on the development of question answering systems. QALD is a benchmarking campaign powered by the H2020 project HOBBIT (project-hobbit.eu) including question answering over (Big) linked data, has been organized as a challenge within CLEF, ESWC and ISWC. This joint workshop hopes to attract people from the two communities in order to promote active collaboration, to extend the scope of currently addressed topics, and to foster the reuse of resources developed so far. Furthermore, we offer an challenge - QALD-9 - where users are free to demonstrate the capabilities of their systems using the provided online benchmark platform. Furthermore, we want to broaden the scope of this workshop series to dialogue systems and chatbots as increasingly important business intelligence factors.

Introduction: Key-Sun Choi (5 min)

Keynote: Peter F. Patel-Schneider (30 min + 10 min Q&A)
Abstract: Connecting Industrial NL Applications to Knowledge (in Nuance)
It seems natural to have speech- and natural language-enabled applications utilize knowledge repositories. The usual situation for fielded industrial applications is quite different, however, with applications employing data sources that are specific to particular, limited tasks. I will make some observations on why this is so and discuss some of the work going on in Nuance to move toward the use of knowledge repositories in industrial speech- and natural language-enabled applications.

Bio: Peter F. Patel-Schneider received his Ph. D. in Computer Science from the University of Toronto in 1987. From 1983 to 1988 he was a member of the Fairchild Laboratory for Artificial Intelligence Research and Schlumberger Palo Alto Research. Peter then joined Bell Laboratories and remained there until 2012 when he joined the Nuance Artificial Intelligence and Language Laboratory. Peter's research interests center on representing large-scale knowledge and information, particularly taking large amounts of data and turning it into knowledge. He has made long-term contributions to description and ontology logics, particularly the W3C OWL Web Ontology Language. He developed much of OWL and its predecessor DAML+OIL, as well as SWRL, the Semantic Web Rule Language, and RDF, the W3C language for representing data in the Semantic Web. Peter has recently been working on extracting semantic information from data sources, allowing data to be more easily integrated into the Semantic Web.
