Identifying Tag Word Counterparts for Dr. Math
Bertram Haskins, Reinhardt A. Botha · National Conference on Artificial Intelligence · 2013
Dr. Math is a South African mobile service which connects high school students experiencing math problems to volunteer human tutors, using the mobile chat platform Mxit. Mxit lingo is a shorthand language used by learners on the platform. Some of the tutors on the Dr. Math service have difficulty in servicing queries received in Mxit lingo. Identifying which of these queries contain valid mathematical questions steals time which could be better spent on the actual tutoring process. This paper develops and tests different techniques for selecting Mxit lingo counterparts for English mathematical tag words. The results of the various techniques are combined according to optimal accuracy and number of usable results. The combined results are used to deliver an XML-based bilingual English / Mxit lingo dictionary for the Dr. Math domain.
