L&C's LinKBase® is the
world's largest medical ontology and one of the
largest ontologies of any kind that is deployed in real-life, mission critical applications. When building
LinkBase® it became obvious that existing off-the-shelf and open-source tools would not meet the performance required for such an undertaking. Necessity being the mother of invention,
L&C developed
LinkFactory®, the only
Ontology Management System built specifically to support, design, and deploy
NLP applications.
LinkFactory® is a feature-rich tool used for building comprehensive corporate terminology systems and is
capable of extracting significant value out of the large stores of unstructured data hidden within corporate documents and databases.
LinkFactory® is specifcally designed to build
ontologies exceeding millions of concepts. It includes advanced features
for performing complex functions such as: 1) attaining the conceptual level of language
expression, 2) managing a large scale and complex ontology and 3) defining relationships
between concepts that extend beyond the simplistic "IS-A", "HAS-A"-type linkages in order
to attain a semantic network.
Furthermore, LinkFactory® provides an effective and user-friendly way to create, maintain and enhance
extensive multilingual terminology systems and
ontologies (English, Spanish, French, etc.). It can
even be applied outside the medical domain and has been successfully tested for applications in Law Enforcement, Defense, etc. Since building a
comprehensive and solid terminology system is time-consuming and labor-intensive,
LinkFactory®
includes several tools that reduce the workload of the knowledge engineer.

Key Features
- The ability to fully model a classification of concepts with all their relevant relationships
and definitions.
- The ability to connect terms in several languages with this conceptual model and use it for
natural language processing.
- The ability to connect the resulting association of terms and concepts with third party
terminology systems such as
SNOMED, Read, ICD-9-CM, ICD-10, MedDRA, etc. (or other classifications
in other domains)
- All entities in the database are versioned so that references can be made to older versions
of objects without losing that information over time.
- OWL/RDF-DL compliance to conform with W3C standards.
Key Benefits
- Customizable user interface: users can define for themselves what view of the
terminology/ontology they need. The right view for the right role.
- Collaborative multi-user editing: unlike other terminology/ontology editors,
LinkFactory®
allows you to work with multiple team members on the same terminology/ontology at the same time.
- Makes mapping between multiple terminology systems and
ontologies routine
- Allows a multilingual approach (linking different languages to a language-independent
conceptual representation) (English, Spanish, French, etc.)
- Can accommodate very large terminologies/ontologies (up to several millions of knowledge objects)
- Minimal processing time
