3rd International Workshop on the Applications of Knowledge Representation and Semantic Technologies in Robotics (AnSWeR19).

Co-located with IROS 2019 (IEEE/RSJ International Conference on Intelligent Robots and Systems), A-rank conference.

Description of the AnSWeR19 Workshop

Autonomous mobile agents and robotics, in general, are experiencing a growing interest due to a number of factors, e.g. the advancements in Artificial Intelligence, Natural Language Processing, and Computer Vision; the amount of new efficient techniques for basic robotic tasks (perception, manipulation, navigation etc.); and the increasing number of cost-accessible robotic platforms in the market. As a consequence, robots will be required to achieve more and more complex tasks, hence exposing the ability to deal with different sources of knowledge about the world in order to improve their behaviors.

While the problem of enabling robots to use available sources of heterogeneous knowledge has attracted attention relatively recently in the robotics community (e.g. the RoboEarth or RoboBrain projects), the Knowledge Representation and Semantic Web communities have been studying techniques to model, integrate and exploit heterogeneous sources knowledge for a long time. We argue that such techniques should also have a role to play in the context of robotic applications, as they could be beneficial for robots to achieve their tasks. The goal It is therefore important to understand how these communities are interfacing, and how they can benefit from each other.

The goal of the AnSWeR workshop is to address these issues by studying the involvement and applications of Knowledge Representation formalisms and semantic technologies in robotic applications, by giving the researchers and practitioners the opportunity to compare and debate on common problems. The AnSWeR workshop will, therefore, allow addressing and debating on problems that have been tackled so far by two communities that worked on overlapping topics.

The first two editions of AnSWeR were held in 2017 and 2018 in Semantic Web conferences to investigate the interests in establishing synergies between both sides. An exciting dialogue between roboticists and knowledge representation practitioners was triggered, encouraging us to maintain and evolve the conversation. We turn this time towards the robotics community and aim at running the third edition of AnSWeR at IROS2019 to strengthen the dialogue and engage a new, wider audience, bridging the gap between these overlapping, but complementary communities. We also firmly believe that by hosting AnSWeR at IROS2019, we will be able to foster conversations among the Asian community, that put profound efforts into the robotics research, and the EU audience, which presents a long-standing tradition in knowledge management and representation.

Challenge Task: Knowledge Extraction from robotic ontologies - Extracting the most popular terms

No idea yet to submit a research paper?

The workshop also offers a challenge task idea for doing analytics on LOV4IoT-Robotics ontology catalog following the research ideas from the Knowledge Extraction for the Web of Things Challenge (KE4WoT). Research can submit their research paper following the challenge idea.

Definition: Loading a set of robotic ontologies and extract the most popular/important terms (e.g., concepts and properties). It would be interesting to have algorithms answering such questions: (1) What are the sensors designed within the ontology (e.g. Body Thermometer)?, (2) What are the logical rules (IF THEN ELSE) designed within the ontology (e.g., if body temperature greater than 38 Degree Celcius than fever)? What is the applicative domain within this ontology (e.g., healthcare) useful when the ontology covers several domains (e.g., robots for cooking, robots for surgery).

Input: A set of ontologies from the LOV4IoT ontology catalog (e.g., robotic ontologies).

Output: For each ontology, finding the most 10 relevant concepts and properties.

 Paper: Concept Extraction from Web of Things Knowledge Bases [Noura et al. 2018]
 Paper: OntoKhoj: a semantic web portal for ontology searching, ranking and classification [Patel et al. 2003] 
 Paper: Identifying potentially important concepts and relations in an ontology [Wu et al. 2008] 

Impact: Such algorithms would demonstrate the most relevant concepts and properties in a set of domains. Hopefully, the algorithm will be generic enough to be applied to any domains. Such algorithms could be relevant to assist to create for instance.

Audience: Robotics communities who want to discover and study already designed models, any developers and/or data scientists willing to make statistics, Knowledge Extraction Experts.

Evaluation: For evaluation purpose, we will choose some ontologies referenced within the set of robotic ontologies mentioned above.

  Criteria 1: What are the sensors/devices described within the ontologies?
  Criteria 2: What are the concepts and properties which can be linked to other ontologies (e.g., Cooking concepts could be linked to food and recipe ontologies)?
  Check here our evaluation tables to show the most common concepts within robotic ontologies

Genericity: To test the genericity of your algorithm, you can play with additional datasets:

Past Workshop Editions and Related Workshops

  • MIRROR workshop at IROS 2016. MIRROR-16, held at IROS in 2016, focused on issues related to the integration of several reasoning systems., i.e. the problem of jointly reasoning about heterogeneous and interdependent aspects of the world, expressed in different forms and at different levels of abstraction.
  • AGAINST workshop at ICRA 2019. AGAINST workshop focuses on bias-sensitization of robot behavior on issues such as gender, race, age, and culture. The goal of this workshop is to raise awareness of and provide new insights into, the biases involved in robot models, human-robot interaction, datasets, and knowledge representation; as well as the techniques which will be required to avoid harmful bias and discrimination by robots.
