"Language resources (ontologies, dictionareis, and corpora) are the core for semantic integration."

DBCLS seeks an in-depth semantic integration of life science databases, and language resources are at the heart of the semantic integration. Several BioNLP projects below are on-going in DBCLS, seeking to improve the systems for the development and management of language resources. As a government-funded public research institute, DBCLS opens its resources and products to the public and interesting parties.


BioNLP Shared Task

  • To promote community collaboration for high level information extraction.


  • To promote community collaboration for literature annotation.
  • To enable exchange and comparison of annotation.


  • A fully configurable, text annotation editor.
  • Works in most of major web browsers with no installation process.


  • To assist ontology building.
  • To promote reuse of existing ontologies.



  • To improve accessibility to linked open RDF data.

    Visualizing BioPortal ontology mappings


    Ontologies in biomedicine are used for several tasks including the standardization of terminology, the verification of data consistency, and the integration of heterogeneous biomedical databases. One can picture a set of biomedical ontologies as a web of biomedical concepts (an analogy to the World Wide Web, where we talk about a web of documents). A single ontology can be described as a group of closely related biomedical concepts....
