Machine Translation systems expect target language output to be grammatically correct. In Myanmar-English statistical machine translation system, target language output (English) can often be ungrammatical. To address this issue, we propose an ongoing chunk-based grammar checker by using trigram language model and rule based model. It is able to solve distortion, deficiency and make smooth the ...

Several authors propose that performative speech acts are self-guaranteeing due to their self-referential nature (Searle 1989; Jary 2007). The present paper offers an analysis of self-referentiality in terms of truth conditional semantics, making use of Davidsonian events. I propose that hereby can denote the ongoing act of information transfer (more mundanely, the utterance) which thereby ente...
