Abstract

This paper proposes an interactive visualization method to support the exploration of data in decision-making and problem solving. Since this method employs an asymmetric communication mode, i.e. taking queries and requests expressed in a natural language as input and answering them with statistical charts, it can convert the normally tedious repetitive human-computer interaction into a felicitous dialogue. This is because the natural language interface allows users to articulate their requests directly and intuitively, and charts and graphics have many benefits when analysing a large amount of data in order to determine overall characteristics or to resolve user questions. The proposed method resolves the conundrum that the appropriateness of a chart depends on the context. In this method, two factors are considered in choosing chart type so as to satisfy the user requirement represented in a natural language: the type of chart displayed and the type of user utterance. Our proposed method allows the data to be visualized interactively to match the changes in the user's viewpoint without interrupting the thinking process.
