Thus, theoretically, this process is a key factor in inference with diagrams, explaining the frequently observed reduction of infere…Read more

13What Makes an Effective Representation of Information: A Formal Account of Observational AdvantagesJournal of Logic, Language and Information 26 (2): 143177. 2017.In order to effectively communicate information, the choice of representation is important. Ideally, a chosen representation will aid readers in making desired inferences. In this paper, we develop the theory of observation: what it means for one statement to be observable from another. Using observability, we give a formal characterization of the observational advantages of one representation of information over another. By considering observational advantages, people will be able to make bette…Read more

Logic, Language and Computation, Volume 3 (edited book)Center for the Study of Language and Inf. 2001.With the rise of the internet and the proliferation of technology to gather and organize data, our era has been defined as "the information age." With the prominence of information as a research concept, there has arisen an increasing appreciation of the intertwined nature of fields such as logic, linguistics, and computer science that answer the questions about information and the ways it can be processed. The many research traditions do not agree about the exact nature of information. By bring…Read more

On the Efficacy of RepresentationDissertation, Indiana University. 1996.We define a "representation" as an external object with which we denote another object and present information about it to ourselves or others. All the following objects count as representations in our sense: a set of Japanese declarative sentences describing Mount Fuji, a time table of the Boston subway system, a geometry diagram used to demonstrate the Pythagorean theorem, a state map of the United States, a relief map of a Rocky terrain, a ballandstick model of a molecular, and a scale mode…Read more
