基于社交网络逐步扩散原理的算法（Algorithm based on gradual diffusion principle of social network） * Model name: the student - customer identification model - Method of social network expanding principle -- Based on Functional Description: by calculating the area of campus speech communication, the number of users set A for each user and student seed users set B voice communication number ratio, voice to frequency ratio, message communication, message communication number number the proportion of the number of short message communication, accounting and other exchanges index, to determine whether the interaction index set each user in A satisfies the LEVEL condition, will meet the conditions of the user selected into real user set B, until the set A does not exist in the interaction index satisfies the LEVEL condition of users so far. - Recommendations: 1, for statistical procedures without changing the calculation process, suggestions placed on the outside of the loop, in order to improve the efficiency of operation; 2, should be judged from the condition LEVEL5~LEVEL1 gradually relaxed conditions, improvement directly determine the conditions of LEVEL1, until no longer exists to meet the conditions of the user, in order to ensure the the accuracy of the model also significantly improve the operation performance. Note: this script provides the core algorithm of this model. For the screening of student seed user set, the provincial companies are required to obtain and calculate according to the actual situation. Model input table: XYSC_CALL_OPPOSITE, XYSC_SMS_OPPOSITE Model output table: XYSC_REAL_STUDENTS * / ----/***** model creates the input table *****/ ----/***** input table 1: the area of campus user voice communication circle table (University) *****/ Create table XYSC_CALL_OPPOSITE ( User_id NUMBER (20,0) Product_no VARCHAR (20) - mobile phone number School_name VARCHAR (128) - belonging to the campus name Opposite_no VARCHAR (32) - end user cell phone number Callcounts NUMB
