This paper presents a corpus study that explores the extent to which captions contribute to recognizing the intended message of an information graphic. It then presents an implemented graphic interpretation system that takes into account a variety of communicative signals, and an evaluation study showing that evidence obtained from shallow processing of the graphic’s caption has a significant impact on the system’s success. This work is part of a larger project whose goal is to provide sight-impaired users with effective access to information graphics. . | Exploring and Exploiting the Limited Utility of Captions in Recognizing Intention in Information Graphics Stephanie Elzer1 and Sandra Carberry2 and Daniel Chester2 and Seniz Demir2 and Nancy Green3 and Ingrid Zukerman4 and Keith Trnka2 1Dept. of Computer Science Millersville University Millersville PA 17551 2Dept. of Computer Science University of Delaware Newark DE 19716 3Dept. of Mathematical Sciences Univ. of NC at Greensboro Greensboro NC 27402 4School of CS Software Engrg Monash Univ.

But as noted by Clark Clark 1996 language is more than just words. It is any signal or lack of signal when one is expected where a signal is a deliberate action that is intended to convey a message. Although some information graphics are only intended to display data values the overwhelming majority of the graphics that we have examined taken Authors can be reached via email as follows elzer@ nlgreen@ carberry chester demir trnka @ .
