- Integrative Models for Natural Language and
Images, Language Grounding
Web data today is increasingly multi-modal, opening up opportunities as well as the need
for integrative models to bridge Natural Language Processing
with Computer Vision.
Our recent explorations include
- Generating natural language descriptions of images
by guiding object detection with language prior
[CVPR-11],
by predicting likely action verbs from language-driven world knowledge
[CoNLL-11],
and by composing phrases retrieved by partial image matching
[ACL-12].
- Understanding
characteristics of visual descriptions
[NAACL-12].
- Constructing a new image-text parallel corpus by reducing information misalignment between images and text
[ACL-13].
|
- Writing Styles, Deception
Detection, Personal Analytics, Forensic Language Technologies
Language is a window into people's minds. We explore data-driven approaches to
statistical stylometry (i.e., the study of linguistic styles),
and forensic language technologies (e.g., authorship verification, obfuscation,
deception detection).
This research is naturally interdisciplinary with
broad connections to Psychology, Social Science, Cognitive Science, Psycholinguistics, and
Literature.
Our recent development includes
- Detecting socio-cognitive identities, such as
authorship [EMNLP-12],
gender [CoNLL-11], and nationality.
- Uncovering (hidden) intent of the authors, such as deception
[ACL-11,
ACL-12,
ICWSM-12],
and textual vandalism [ACL-11].
