In view of the existence of a lot of spam comments in microblog,a new method based on AdaBoost was proposed to identify spam comments. This method firstly extracted feature vectors which consisted of eight feature values to represent the comments,then trained several weak classifiers which were better than random prediction on these features via AdaBoost algorithm,and finally combined these weighted weak classifiers to build a strong classifier with a high precision. The experimental results on comment data sets extracted from the popular Sina microblogs indicate that the selected eight features are effective for the method,and it has a high recognition rate in the identification of spam comments in microblog.

Concerning the problem that Artificial Bee Colony(ABC) is good at exploring but lack of exploitation,two new solution search strategies named PSO-DE-PABC and PSO-DE-GABC were proposed based on Particle Swarm Optimization(PSO) and Differential Evolution(DE). PSO-DE-PABC generated new candidate position around the random particle to improve divergence. PSO-DE-GABC generated new candidate position around the global best solution to accelerate the convergence,and differential vectors were also used to increase the divergence. Besides,Dimension Factor(DF) was introduced to control the search rate of the algorithms. A new scout strategy considering current swarm state was used to replace the original random scout strategy to enhance the local search ability. Comparison with basic ABC,GABC(Gbestguided ABC) and ABC / best algorithm was given on 10 groups of standard benchmark function. The results show that PSO-DEGABC and PSO-DE-PABC have better convergence rate and accuracy.
