In this paper, we present a system that automatically extracts lexicalized tree adjoining grammars (LTAG) from treebanks. We first discuss in detail extraction algorithms and compare them to previous works. We then report the first LTAG extraction result for Vietnamese, using a recently released Vietnamese treebank. The implementation of an open source and language independent system for automa...

This paper introduces a Vietnamese text-based conversational agent architecture on specific knowledge domain which is integrated in a question answering system. When the question answering system fails to provide answers to users’ input, our conversational agent can step in to interact with users to provide answers to users. Experimental results are promising where our Vietnamese text-based con...

Strong doctor-patient relationships generate greater patient satisfaction and compliance with physician recommendations. Although prior research has explored distinct factors driving favorable patient outcomes, investigations have yet to comprehensively address the efficacy of different communication styles. Furthermore, it is critical to explore the full impact communication approaches have on...

In this paper, we present work on understanding Vietnamese sign language through the use of Micro Electronic Mechanical System (MEMS) accelerometers. The system consists of six ADXL202 accelerometers for sensing the hand posture, a BASIC Stamp microcontroller and a PC for data acquisition and recognition of sign language. The data is then transformed to relative angles between fingers and the p...

The article proposes a distributed syntax for Vietnamese and Chinese focus particle sentences. It disentangles syntactically the inclusion and exclusion of alternatives typical of focus particle uses from scalar components of meaning that many focus particle sentences convey. Vietnamese and Chinese are shown to have highly elaborate lexical paradigms that map plausibly onto the postulated synta...

OBJECTIVES This report compares the health status of selected Asian national origin groups. METHODS 1992-94 National Health Interview Survey (NHIS) data were analyzed for six Asian national origin groups (Chinese, Filipino, Asian Indian, Japanese, Vietnamese, and Korean), the Asian and Pacific Islander (API) population as a whole, and the non-Hispanic white population. Unadjusted and age-adju...

Objective: To estimate costs associated to hospital treatment of urinary lithiasis in the Brazilian public health system as well as to evaluate demographic and epidemiological data referred to hospital admissions in the Brazilian public health system (or unified health care system). Methods: Data from the Informatic Department of Brazilian public health system were obtained as referred to costs...

In this paper, we describe the development of an end-to-end factoid question answering system for the Vietnamese language. This system combines both statistical models and ontology-based methods in a chain of processing modules to provide high-quality mappings from natural language text to entities. We present the challenges in the development of such an intelligent user interface for an isolat...

The principles of patient centred care and the mantra of “nothing about me without me” have gained broad support, but its proving hard to adopt and embed them in routine practice. New ways of thinking and tackling resistance to change are needed, and a range of initiatives are being pursued. We describe the approach being taken in New South Wales, Australia’s most populous state, with 7.4 milli...
