The business of monitoring, measuring and understanding social media
Viralheat Packages Sentiment Engine Into Hardware Appliance for Customer Data Centers
Viralheat 
has introduced its Sentiment Analysis Appliance, a preconfigured computer server for installation in customers' data centers. The appliance duplicates the function and access methods of Viralheat's existing sentiment analysis API, which has been available as a free service since 2011.
Viralheat's primary business is its SaaS-based social media management platform, which the company describes as a unified tool for social media monitoring, measurement, analytics, and engagement management. It opened access to its sentiment analysis functions to improve its algorithms through wider use.
The new appliance is functionally equivalent to the public API, using the same hardware and software as Viralheat's own systems. The company introduced the deployed hardware model to address the hosted service's performance constraints (on latency and throughput) and concerns about data security from developers who work with government or financial data.
Viralheat's Sentiment Analysis Appliance is available through an annual lease program. The company did not discuss pricing.
