Developing a Tagalog Linguistic Inquiry and Word Count (LIWC) ‘Disaster’ Dictionary for Understanding Mixed Language Social Media: A Work-in-Progress Paper

Abstract

In the wake of super typhoon Yolanda (known internationally as Haiyan) in the Philippines in 2013, many individuals in the Philippines turned to social media to express their thoughts and emotions in a variety of languages. In order to understand and analyze the sentiment of populations on the ground, we used a novel approach of developing a conceptual Linguistic Inquiry and Word Count (LIWC) dictionary comprised of Tagalog words relating to disaster. This work-in-progress paper documents our process of filtering and choosing terms and offers suggestions for validating the dictionary. When results on how the dictionary was used are available, we can better assess the process for creating conceptual LIWC dictionaries.
