Method and system for providing technology change using of technology life cycle graph

A system for providing a technology trend using a technology lifecycle graph, the system comprising:

• a technology trend information database construction device which constructs a technology trend information database in which year-specific stages and year-specific representative principal agents with respect to each technology to be displayed on a technology lifecycle graph are stored;
• and
• a technology trend providing device which obtains year-specific stages or year-specific representative principal agents with respect to a specific technology displayed on the technology lifecycle graph and displays the obtained year-specific stages or year-specific representative principal agents on the technology lifecycle graph,
• wherein the technology trend providing device displays the representative principal agent in each year together with the magnitude of a result by linking to the corresponding year and displays a change speed, which represents the time required by the specific technology to move to a next stage, on a node corresponding to the year-specific stage.

A technology trend information database construction device comprising:

• a technical glossary in which technical terms to be displayed on a technology lifecycle graph are defined;
• a literature analysis unit which obtains literatures including technologies defined in the technical glossary by analyzing literatures stored in a heterogeneous literature providing device and extracts principal agents from the obtained literatures;
• a year-specific stage determination unit which determines year-specific stages of each technology by classifying the obtained literatures for each year;
• a year-specific representative principal agent acquisition unit which classifies the principal agents of the extracted literatures for each year and obtains a principal agent having the largest magnitude of a result from the principal agents classified for each year as a year-specific representative principal agent;
• and
• a technology trend information database management unit which creates a technology trend information database in which year-specific stages and year-specific representative principal agents with respect to each of the obtained technologies are stored.

A technology trend providing device comprising:

• a technology trend information acquisition unit which obtains year-specific stages or year-specific representative principal agents with respect to a specific technology displayed on a technology lifecycle graph;
• and
• a visualization unit which displays the obtained year-specific stages or year-specific representative principal agents on the technology lifecycle graph,
• wherein the visualization unit displays the representative principal agent in each year together with the magnitude of a result by linking to the corresponding year and displays a change speed, which represents the time required by the specific technology to move to a next stage, on a node corresponding to the year-specific stage.
