However, they lack communication abilities, which limits the task of question answering to simply querying the dataset. There are two reasons why question answering systems do not develop into further communication although question answering is apparently a type of communication: first, the systems are not leveraging the rich information they have. Second, they are inflexible and inadaptable as they aim to be a robust system. In fact, it is difficult to guess the intention of a person precisely because natural language has ambiguities at different levels. Apart from the ambiguity of natural language, people have diversity due to social and cultural factors. Dialogue-based question answering is a way to overcome the limitations of not properly deploying the large data and not coping with the ambiguity in question answering. The paper defined a dialogue-based question answering system as a system that uses communication strategies: (i) to provide the user with information proactively and (ii) to accommodate user reactions. The use of the systems information allows to enrich the question answering conversation, and the use of the users feedback allows to continue the rich conversation coherently. First, the paper introduced question answering systems and communication theory to construe question answering as a form of communication. Next, it analyzed the WikiQA dataset and presented eleven types of errors which occurred in the actual use of question answering systems but could not be handled by the performance improvement of each module in the systems. After introducing how dialogue can be integrated in question answering systems in terms of extended speech act and the error types, it pilot-tested a question answering chatbot. The result showed that the two communication strategies could be another interface that helps both the user and the system explore huge data spaces by letting them make agreements and recover errors.Chapter 1.

This study evaluated the weights of attributes for different types of multi-modal transfer centers. They were classified into three types: national, regional, and local multi-modal transfer centers. Attributes for planning were also divided into three types by their functions: mixed-use, transfer, and ripple effects. Using analytic hierarchy process (AHP), the differences in weights for attribute types were found. The dissimilarity in the weights between planners and transportation professionals were also observed from the survey. While both groups evaluated transfer as significant, planners tended to consider mixed-use more importantly. Attributes for planning of multi-modal transfer centers thus should not be reviewed uniformly but comprehensively, considering their aims of application.N

Mega-event is an official function held irregularly (occasionally regularly) on a large scale, such as the 2002 World Cup, Expo 2012 Yeosu, 2014 Incheon Asian Game, etc. These mega-events attract participants and spectators everywhere, resulting in high concentration of traffic around the venue and the nearby areas. Event organizers make efforts to mitigate traffic congestion by providing various means of transport service. In that, it is meaningful to develop a tool to make a decision to provide an appropriate level of transport service for the event. Thus, as the basic indicator of the opportunity cost approach, this paper estimates monetary value of the travel time of spectators in the event peak times. A discrete choice model is applied to the analyses along with an SP data from the interviews of 313 visitors in the 2015 Gwangju Universiade. It reveals that the value of travel time of public transit (bus) users at the event peak time is 3,603 won per hour per person, which is lower than that of the average business trips of 15,918 won but is higher than the average non-business trips of 3,041 won.N

    Hedonic estimates of rail noise in Seoul

    The paper offers a valuation of urban rail noise in South Korea using the hedonic pricing method. It considers trade-offs in the context of housing prices, locality, and environment intrusion. The model adopted provides a reasonable explanation of the determinants of property values, with a unit increase in dB(A) decreases property value by 0.53% in the Seoul area. (c) 2012 Elsevier Ltd.
