Koike, a B4 student in Hayashi Laboratory, gave an oral presentation titled "Extraction of Constituent Factors of Digestion Efficiency in Information Transfer by Media Composed of Texts and Images" at the 29th Annual Meeting of the Association for Natural Language Processing (NLP2023).

This is a part of his graduation thesis. By introducing the concept of "information digestion," he proposed a model for evaluating information digestibility using hierarchical factor analysis and extracted the factors constituting digestibility by four types of media through the subject experiment. Conventional evaluation of information transfer only covers the point at which information reaches the receivers, but this study covered the receivers' understanding of the contents and purposes of the acquired information, which is expected to be applied to methods that support information receivers in obtaining information that is valuable to them.

This research is part of the results of Value Exchange Engineering, a joint research project between R4D, Mercari Inc. and the RIISE, and the JSPS Kakenhi (JP20H02384) "Elucidation of the Dynamics of Data Markets and Institutional Design."

Title: Extraction of Constituent Factors of Digestion Efficiency in Information Transfer by Media Composed of Texts and Images

Authors: Hiroaki Koike (Univ. of Tokyo), Teruaki Hayashi (Univ. of Tokyo)

Abstract: The development and spread of information and communication technologies have increased and diversified information. However, the increase in the volume and the selection of information does not necessarily promote understanding. In addition, conventional evaluations of information transfer have focused only on the arrival of information to the receivers. They need to sufficiently take into account the receivers' understanding of the information after it has been acquired, which is the original purpose of the evaluation. In this study, we propose the concept of "information digestion," which refers to the receivers' correct understanding of the acquired information, its contents, and its purpose. In the experiment, we proposed an evaluation model of information digestibility using hierarchical factor analysis and extracted factors that constitute digestibility by four types of media.
