Workshop on Combination of Symbolic and Sub-symbolic Methods and their Applications (CSSA)
Co-located with ECML/PKDD 2021

Web: https://alammehwish.github.io/cssa_ecml_pkdd_2021/ 
Deadline: June 23rd, 2021
Since the beginning of the 2000s, there has been an increasing number of studies and standards proposed for generating large-scale symbolic representations of knowledge (known as Knowledge Graphs (KGs)) out of heterogeneous resources such as text, images, etc. Moreover, there have been many advances in symbolic reasoning as well as their applications to various fields. Recently, sub-symbolic methods have gained momentum. These methods aim at generating distributed representations from several resources such as text or symbolic representations (Graph Neural Networks, KG embeddings, etc.). These sub-symbolic methods for symbolic representations mainly focus on the task of KG completion. However, these have also recently been used for various tasks such as Natural Language Processing (NLP). The future of these methods would be a combination of these approaches leading to neuro-symbolic reasoning. Advances in the real-world applications related to these methods will also serve as a stepping stone in the practicality of these methods.

Topics of interest:
Topics include but are not limited to:

Methods for combining symbolic and sub-symbolic approaches
- Capturing formal semantics in sub-symbolic systems
- Explainability in  Symbolic and Sub-symbolic methods
- Bias in Symbolic and Sub-symbolic methods
- Methods for generating KG embeddings
- Knowledge Evolution
- Temporal Aspects in Knowledge Graphs

Applications of symbolic and sub-symbolic methods

- Information and Knowledge Management Systems
- Link Prediction and KG Completion
- Ontology Learning and Matching exploiting KG Embeddings
- Image/Multi-modal Processing
- KG based Sentiment Analysis
- Natural Language Processing, and Understanding
- Question Answering
- Domain-Specific KGs (Scholarly, Biomedical, etc.)
