Our team has created a unique technology that demonstrates how machine learning ideas can be applied successfully at web-scale. Worio has developed and integrated: (i) novel classifiers that automatically apply millions of tags to billions of documents accurately and within a day, (ii) a massive web-scale recommender system for millions of users and billions of items, and (iii) topic modeling of users, documents and queries. The technology opens up room for new products in knowledge discovery and information retrieval, filtering and organization. It is also a platform for developing more sophisticated-scale natural language applications.
