All companies face hidden costs in the form of lost revenue due to unhappy customers not returning and potential customers snubbing a product due to bad publicity. This thesis develops an aspect-based opinion summarization system capable of extracting opinion features from product reviews, determining the sentiment of the reviews the opinion features appeared in and producing a summary of the most frequent features discussed with regards to sentiment. The results from the summary system are promising but could still be improved to produce even more value." }
