The theoretical backgrounds of CPMw, Link community, and EAGLE, which are overlapping community detection models in weighted networks are presented, and the model is fitted to the cosponsorship network of the 17th National Assembly. The performances of the models are compared using the modified modularity, community cov- erage and overlapping coverage. Since cosponsorship networks represent political relationships among the legislators, the political networks can be found from statistical communities. Therefore, we compare the communi- ties derived from the optimal models with the political parties of legislators and examines characteristics of the parties in the 17th National Assembly.Introduction ........................... 1 Statistical models ........................ 6 2.1 Notation............................ 6 2.2 CPMw............................. 7 2.3 Link Community ....................... 8 2.4 EAGLE ............................ 10 Case study ............................ 13 3.1 17๋Œ€ ๊ตญํšŒ ๊ณต๋™๋ฒ•์•ˆ ๋ฐœ์˜ ๋ฐ์ดํ„ฐ............... 13 3.2 ๋ถ„์„ ๊ฒฐ๊ณผ ........................... 14 Conclusion ............................ 24 Abstract................................. 28Maste
