Research Interests
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.
Natural Language Processing
Structured Prediction, Named Entity Recognition, Multimodal Processing
