2010). Silvescu et al. propose the system EMERSE for classifying and aggregating tweets and text messages about the Haiti earthquake disaster. They train a SVM classifier with the combination of 4 feature sets: unigrams, unigrams with Relief feature selection, abstractions, and topic words generated by LDA (Silvescu et al. 2009). 1 Data Collection Two dataset are collected during the experiment: a microblog dataset and an ILI dataset from the official website. The microblog dataset is mainly used in the experiment and test the ability of new generated model.

5. Sort the n candidate by the value of probability P. 6. Return: Top k of the sorted n candidates as the list of friend recommendation result. The pseudo-code of recommendation algorithm FRUITA is shown in Algorithm 1. In step 3, if calculating each P of the attribute costs time m and there are n attributes, 38 Z. Zhang et al. the time complexity of step 3 is O(mn); in step 4, if calculating each P of the candidates costs time m and there are n candidates, the time complexity of step 4 is O(mn); in step 5, we use the function “Rank()” in SQL to sort the results and the time complexity of step 5 is Oðn log nÞ.
