loom

Loom is a knowledge representation language developed by researchers in the Artificial Intelligence research group at the University of Southern California's Information Sciences Institute. The project's objective is the creation and fielding of advanced tools for knowledge representation and reasoning in Artificial Intelligence. Even though Loom software is licensed under open source licenses, it is still the intellectual property of the University of Southern California and it is not in the public domain. Loom is succeeded by PowerLoom.

• Loom is one of the tools being used to develop and view HPKB ontologies. The High Performance Knowledge Base (HPKB) program develops theories, tools, and knowledge bases in support of advanced reasoning about complicated issues arising in battle management and crisis understanding.

• Loom is utilized in the JFACC project—a DARPA project to develop a tool to assist the Joint Forces Air Component Commander create air campaign plans. One of the applications developed with Loom on this project is the Strategy Development Assistant (SDA).

• Ontosaurus is a Web-based browser for Loom and PowerLoom knowledge bases. It offers a dynamically generated, hyper-linked interface to both Loom and PowerLoom theories.

• Loom is used in The EXPECT project as the representation language for constructing knowledge acquisition tools. EXPECT is developing a knowledge acquisition framework empowering users and domain experts to augment, modify, and adapt knowledge-based systems without an understanding of the details of the system's implementation.
