Abstract
A device and method for reviewing literature by using Latent Dirichlet Allocation (LDA) is proposed. The device may include a pre-processing unit extracting text data for modeling, and a modeling unit automatically classifying topics as many as a set number (K) and generating a probability distribution of the topics by literature and a probability distribution for words by topic. The device may also include a clustering unit updating the number (K) of the topics, an interest analysis unit confirming trends by topic over time, and a generality analysis unit quantitatively confirming a research scope of each specific topic. The device may further include a similarity analysis unit quantitatively confirming a similarity between the topics, a network analysis unit quantitatively confirming a correlation between the topics, and a display displaying the trends by topic over time, research scope of each specific topic, similarity between the topics, and correlation between the topics.
