1. A technology transition visualization apparatus including a storage and a processor and comprising: a bibliographic database configured to integrate heterogeneous resources; a technology information database configured to store information on a representative stage, a current stage, a next stage, and a year-specific stage included in a technology lifecycle of each technology; an interface module configured to receive a specific technology from a user; a feature set creation module configured to calculate feature values of predefined features by searching the bibliographic database and to create a feature set for each technology using the calculated feature values, for technologies positioned on a technology lifecycle; an answer feature set creation module configured to calculate a common feature value of feature sets of technologies belonging to the same stage in the technology lifecycle and to create an answer feature set of each stage; a stage determination module configured to, if a specific technology is inputted through the interface module, acquire feature-related information for the specific technology by searching the bibliographic database, to create a representative feature set and a year-specific feature set of the specific technology using the acquired feature-related information, to determine a representative stage or a year-specific stage where the specific technology belongs to in the technology lifecycle by comparing the representative feature set or the year-specific feature set with the answer feature set, and to estimate development speed of the specific technology using the year-specific stage; a visualization module configured to visualize the technology lifecycle which shows the representative stage of the specific technology; and a year-specific stage acquisition module configured to, if the specific technology is selected from the visualized technology lifecycle, acquire a current stage, a year-specific stage and an estimated next stage of the specific technology from the technology information database and to visualize the acquired stages through the visualization module, wherein the stage determination module includes: a feature-related information acquisition unit configured to, if the specific technology is inputted, acquire feature-related information for calculating feature values of features contained in a predefined feature set by searching the bibliographic database; a feature value calculation unit configured to calculate a representative feature value of each feature using the acquired feature-related information and to calculate year-specific feature values by classifying the feature-related information by the year; a feature set creation unit configured to create a representative feature set using the calculated representative feature values and to create a year-specific feature set using the year-specific feature set; a stage determination unit configured to determine a representative stage where the specific technology belongs to in the technology lifecycle by comparing the representative feature set with the answer feature set, and to determine a year-specific stage of the specific technology by comparing the year-specific feature set with the answer feature set; and a development speed estimation unit configured to estimate a stage where the next stage of the specific technology will belong to in the technology lifecycle or a time required to move to the next stage, using the determined year-specific stage.
