BMTutor research design: Malay sentence parse tree visualization

摘要

This paper discusses the research design for BMTutor. BMTutor is a prototype for visualizing Malay sentences that is combined with sentence checker, sentence correction and word attribute components. The purpose of BMTutor is to check sentence validation, provide sentence correction for invalid sentence used and produce parse tree visualization. The research design involved can be divided into four phases; categorizing sentence and produce repository (Phase 1), developing models and algorithms (Phase 2); development of a prototype (Phase 3); and prototype testing (Phase 4). To date, this system is the only one designed with the functions and characteristics as in BMTutor. There are two BM parsers to check the validity of simple BM sentences had been developed. Both parsers performed three phases in research design, namely 1) the collection of sentence or CFG, 2) develop a prototype, and 3) conduct evaluation. The phases involved are the basic method in developing a prototype. As a result of the lack of models and algorithms have been introduced in both parsers, the model and algorithm development phase is introduced in the design of BMTutor. Output from the development process shows that the prototype is able to provide sentence correction for all 15 invalid sentences and can produce parse tree visualizations for all 20 sentences used for prototype testing.
