Digimind is a social media listening and monitoring tool
leveraging on the results of emotion recognition in text. It was a
B2B company based in Paris. What do we see in this particular
example? On the upper left side: it’s comparing the different
smart phones: how users discuss, perceive these brands.
You can analyze topics and track
competitors using this tool. You can monitor and analyze sub-
topics within the larger topic. Drill down into details on what's
happening, when it's happening, where, who's talking about you
(your key influencers) and how (what's the sentiment).
