• Geography & Language
  Currently, I am very interested in the intersection between Geographic Information Science (GIS) and Natural Language Processing (NLP). In order to reach the potential of the two fields, our Geography & Language project tries to connect between maps and text; i.e., grounding location-related expressions onto a map.
