Research Abstract

Two types of brain activity measurement experiments were executed. Generation of search query is an important process because without this step the information search process cannot start, and the selection of query keywords directly influences the quality of the search result. The two types differ in the text amount that is displayed to the subject and the generation method of search keyword. Analysis of fMRI experimental data indicates the presence of a common brain network and brain networks specific to each search task.
