The LinKFactory® tool provides an effective and user-friendly way to create, maintain and extend extensive multilingual terminology systems and ontologies (English, Spanish, French, etc.). It can even be applied outside the medical domain and has been successfully tested. Since building a comprehensive and solid terminology system is very time-consuming and labor-intensive, it is essential to have the right tools to reduce the workload of this kind of project. LinKFactory® is very powerful, yet easy to learn and manage.
