Abstract
The goal of our research is to develop a multimodal summarization system that provides trend information composed by multiple modalities (e.g., texts and visual expressions) based on user interest. For that purpose, this paper proposes a method of statistical chart generation from multiple documents. Since sucsource documents often lack a sufficient number of explicit expressions (e.g., “$15”) to correctly draw statistical charts, a system for generating such a chart must appropriately compensate for such missing information. To satisfy this requirement, our proposed method utilizes background knowledge and two types of expressions: comparison expressions (e.g., “increase by 30%”) and qualitative expressions (e.g., “'stable” and “increase slightly”), along with explicit expressions. Our preliminary study reveals that (1) information for drawing a chart can be doubled or more by using background knowledge and comparison expressions and that (2) user comprehension of a generated chart was improved by using qualitative expressions.
