Second Call for Papers: SemDeep-6@IJCAI-PRICAI deadline extended

Dear colleagues, 

please find below the second call for papers for the 6th Workshop on Semantic Deep Learning (SemDeep-6) colocated with IJCAI-PRICAI. 

We would like to point your attention to the fact that we will in any case organize the workshop, even though it will probably become an online event. Furthermore, we have decided to extend the submission deadline to May 15. 

Please consider the event as a venue for your work, feel free to forward this call and please accept our apologies if you receive this call more than once. 

Kind regards,
Dagmar, Luis, Thierry 


SECOND CALL FOR PAPERS FOR THE 6TH WORKSHOP ON SEMANTIC DEEP LEARNING AND THE WiC-TSV CHALLENGE
SemDeep-6@IJCAI-PRICAI 2020

Yokohama, Japan from July 11-17, 2020

It is likely that the workshop will be organized as an online event. 

=====================================================
SemDeep extended submission deadline: 24 April 2020  15 May 2020 (00:00 CEST) 
WiC-TSV Challenge end of evaluation: 1 May 2020  
=====================================================

The 6th Workshop on Semantic Deep Learning (SemDeep-6) <http://www.dfki.de/~declerck/semdeep-6/> and the WiC-TSV challenge <https://competitions.codalab.org/competitions/23683> will be collocated with IJCAI-PRICAI <https://ijcai20.org/> in Yokohama, Japan, this year.  

Semantic Web (SW) technologies and Deep Learning (DL) share the goal of creating intelligent artifacts. Both disciplines have had a remarkable impact in data and knowledge analysis, as well as knowledge representation, and in fact constitute two complementary directions for modeling linguistic phenomena and solving semantically complex problems. In this context, and following the main foundations set in past editions, SemDeep-6 aims to bring together SW and DL research as well as industrial communities. 

SemDeep-6 is interested in contributions of DL to classic problems in semantic applications, such as: (semi-automated) ontology learning, ontology alignment, ontology annotation, duplicate recognition, ontology prediction, knowledge base completion, relation extraction, and semantically grounded inference, among many others. At the same time, we invite contributions that analyse the interaction of SW technologies and resources with DL architectures, such as knowledge-based embeddings, lexical entailment, relation classification or knowledge base completion. This year we are particularly interested in how this combination can contribute to the bigger field of Explainable AI. This workshop seeks to provide an invigorating environment where semantically challenging problems which appeal to both Semantic Web and Deep Learning communities are addressed and discussed.

KEYNOTE SPEAKER 
We are happy to announce that Michael Spranger, a researcher at Sony Computer Science Laboratories Inc. in Tokyo, Japan, who has been actively contributing to neural-symbolic learning and reasoning, has agreed to give a keynote at SemDeep-6.

WiC-TSV CHALLENGE
Word Sense Disambiguation (WSD) is a long-standing task in Natural Language Processing and Artificial Intelligence. While progress has been made in recent years, the evaluation of WSD models has been limited to a set of (mostly SemEval-based) standard datasets. 

The SemDeep-6 workshop includes a challenge (shared task) based on a new multi-domain evaluation benchmark for WSD “Target Sense Verification for Words in Context” (WiC-TSV). 

The main difference between WiC-TSV and common WSD task statement is that in WiC-TSV there is no standard sense inventory that systems need to model in full. Each instance in the dataset is associated with a target word and single sense, and therefore systems are not required to model all senses of the target word, but rather only a single sense. The task is to decide if the target word is used in the target sense or not, a binary classification task. Therefore, the task statement of WiC-TSV resembles the usage of automatic tagging in enterprise settings.

For the WiC-TSV challenge training, development and test sets will be provided (training and development sets already available). For more information and instructions on how to participate, please visit https://competitions.codalab.org/competitions/23683 <https://competitions.codalab.org/competitions/23683>.
