Thomson Reuters, a US-based provider of information for businesses and professionals, has announced that, in response to publisher and enterprise demand, it is offering commercial options for its Calais web service. With this initiative, the company seeks to bring reliable metadata generation services to companies of all kinds.
Found at OpenCalais.com, the Calais web service makes it easy to tag the people, places, facts and events in content, increasing its relevance and search accessibility. The new commercial options seek to offer increased capacity and customisation for publishers and businesses that require service-level agreements and/or a deployed version of Calais that can live behind their firewall.
The Calais suite of services now includes OpenCalais; Calais Professional; Calais Professional for Publishers, and Calais Enterprise. OpenCalais includes the free Calais web service, its open API, and the resources at OpenCalais.com. It offers the full Calais functionality, and enables users to submit up to 40,000 content transactions per day at a maximum rate of four transactions per second. Calais Professional provides the same OpenCalais functionality with a high-performance service-level agreement, 24x7 monitoring, an increased daily transaction limit of 100,000, and an enhanced rate of 20 transactions per second. Additional transaction volume blocks of up to 2,000,000 transactions per day are also available.
Calais Professional for Publishers is targeted at larger scale publishers and is available as an annual contract. Calais Enterprise installs a customised version of Calais within a company's processing environment that can easily scale to tens of millions of transactions per day and many thousands of transactions per minute. In addition to the core Calais functionality, Calais Enterprise gives users the ability to modify their instance of the Calais metadata generation engine to create new entities and relations, and to incorporate user lexicons.
