ONTOLOGY-BASED SEARCH SERVICE SYSTEM AND METHOD THEREOF

摘要

The present invention relates to a search service system and a method thereof. More specifically, the present invention relates to an ontology-based search service system which searches for a search keyword in a triple data list including subjects, objects, and predicates, and expresses the relations thereof in a network graph. According to the present invention, the search service system includes: a triple store storing triple data lists which is multiple sets of triple data made of nodes including subjects and objects of the subjects, and edges including the relations between the subjects and objects; a triple search module searching for a triple data list related to a search keyword inputted from a user in the triple store; and a network graph search module displaying the shape of a network graph including the search keyword, node lists including the subjects in the triple data found with the search keyword, and an edge list connecting the node lists based on the triple data list found in the triple search module. In addition, the present invention visualizes the relations between data to easily recognize the same, thereby significantly reducing the analysis time.;COPYRIGHT KIPO 2019
