Knowledge representation is therefore an important aspect of the system.
Ideally, the system would be able to do natural language processing, where the computer can analyze oral or written text and create its own representation. However, computers are not yet able to do this in a generalized manner. For a conceptual retrieval system to work, the computer must be able to retrieve not only important facts, but also higher-level significant themes. For statutory interpretation, this process is aided by the inherent categorization of the statutes. However, the statutory construction still needs to be hand-crafted at this time.
