| Abstract | In this study, we extracted brain activities related to semantic relations anddistances to improve the precision of distance calculation among concepts inthe Associated Concept Dictionary (ACD). For the experiments, we used amulti-channel Near-infrared Spectroscopy (NIRS) device to measure the responseproperties of the changes in hemoglobin concentration during word-conceptassociation tasks. The experiments’ stimuli were selected from pairs ofstimulus words and associated words in the ACD and presented in the form of avisual stimulation to the subjects. In our experiments, we obtained subjectresponse data and brain activation data in Broca's area ―a human brainregion that is active in linguistic/word-concept decision tasks― and thesedata imply relations with the length of associative distance. This study showedthat it was possible to connect brain activities to the semantic relation amongconcepts, and that it would improve the method for concept distance calculationin order to build a more human-like ontology model. |
