NER for Vietnamese Spoken Texts and Its Application in Smart Mobile Voice Interaction

NER for written documents has been studied intensively during the past decades. However, NER for spoken texts is still at its early stage. There are several challenges behind this: spoken texts are usually less grammatical, all in lowercase, and even have no punctuation marks; continuous text chunks like email, hyperlinks are interpreted as discrete tokens; and numeric texts are sometimes interpreted as alphabetic forms. These characteristics are real obstacles for spoken text understanding.
