Twitter sentiment monitoring tool Chatterscope launched by Lewis PR

Chatterscope provides users of Twitter with an aggregated result that determines whether the sentiment of their brand at that time is positive, neutral or negative.

There is also the option of alerts at hourly, daily or weekly intervals.

Lewis PR director of product development Ian Lipner said: 'While no sentiment analysis engine working with 140 characters approaches more than 95% accuracy, Chatterscope is one that PR teams can use right now to get a quick read of their brands’ sentiment on Twitter ­– and an even quicker heads-up when something changes.'
