The aim of the project is to develop novel techniques to construct advanced types of Knowledge Graphs. Current generation of Knowledge Graphs is mostly limited to unary and binary factual knowledge; they do not have a particularly strong model for knowledge whose existence depends critically on certain spatial/temporal/contextual conditions.
The challenges involved in this research include:
- How to model and extract spatial/temporal/contextual knowledge?
- How to model and extract n-ary relation?
- How to extract commonsense Knowledge?
