The well-known technology analyst Stephen Arnold has published a review about Bitext's Local Sentiment services in Beyond Search: "Bitext Delivers a Breakthrough in Localized Sentiment Analysis".
In his words:
The Bitext approach goes well beyond the three stars or two dollar signs approach of some systems. Bitext can evaluate topics or “aspects”. The system can generate opinions for each topic or facet in the content stream. Furthermore, Bitext’s use of natural language provides qualitative information and insight about each topic revealing a more accurate understanding of specific consumer needs.
