This paper describes our SeemGo system for the task of Aspect Based Sentiment Analysis in SemEval-2014.The subtask of aspect term extraction is cast as a sequence labeling problem modeled with Conditional Random Fields that obtains the F-score of 0.683 for Laptops and 0.791 for Restaurants by exploiting both word-based features and context features.The other three subtasks are solved by the Maximum Entropy model,with the occurrence counts of unigram and bigram words of each sentence as features.
