Linx is a German B2B search engine serviced by ATEC. Like Hotfrog, Linx works with a large database with information about companies and their products and services. To build up the database Linx offers a subscription form, to be filled in by companies. Irion built a dedicated information extraction tool to fully automatically extract products and services from crawled company websites. The natural language technology used in the system could also be tuned to automatically generate a product and services taxonomy.
