Abstract This paper describes CLIME, a web-based legal advisory system with a multilingual natural language interface. CLIME is a ‘proof-of-concept’ system which answers queries relating to ship-building and ship-operating regulations. Its core knowledge source is a set of such regulations encoded as a conceptual domain model and a set of formalised legal inference rules. The system supports retrieval of regulations via the conceptual model, and assessment of the legality of a situation or activity on a ship according to the legal inference rules. The focus of this paper is on the natural language aspects of the system, which help the user to construct semantically complex queries using WYSIWYM technology, allow the system to produce extended and cohesive responses and explanations, and support the whole interaction through a hybrid synchronous/asynchronous dialogue structure. Multilinguality (English and French) is viewed simply as interface localisation: the core representations are language-neutral, and the system can present extended or local interactions in either language at any time. The development of CLIME featured a high degree of client involvement, and the specification, implementation and evaluation of natural language components in this context are also discussed.
Executive Summary
The article discusses CLIME, a multilingual legal advisory system that utilizes natural language processing to provide users with guidance on ship-building and ship-operating regulations. The system features a conceptual domain model and formalized legal inference rules, allowing for complex queries and extended responses. CLIME supports both English and French languages, with a hybrid synchronous/asynchronous dialogue structure. The development of CLIME involved significant client involvement, and the article highlights the importance of natural language components in the system's design and evaluation.
Key Points
- ▸ CLIME is a web-based legal advisory system with a multilingual natural language interface
- ▸ The system uses a conceptual domain model and formalized legal inference rules to provide guidance on ship-building and ship-operating regulations
- ▸ CLIME features a hybrid synchronous/asynchronous dialogue structure and supports both English and French languages
Merits
Effective Query Construction
The system's use of WYSIWYM technology enables users to construct semantically complex queries, making it easier to retrieve relevant information and assess the legality of a situation or activity.
Demerits
Limited Domain Knowledge
The system's core knowledge source is limited to ship-building and ship-operating regulations, which may restrict its applicability to other areas of law.
Expert Commentary
The article provides a compelling example of the potential benefits of integrating natural language processing into legal advisory systems. The use of a conceptual domain model and formalized legal inference rules enables CLIME to provide nuanced and context-specific guidance, while the multilingual interface expands the system's reach and accessibility. However, the limited domain knowledge of the system highlights the need for further research and development to expand the scope and applicability of such systems. As the field of artificial intelligence in law continues to evolve, it is essential to consider the implications of these developments for the provision of legal services and the administration of justice.
Recommendations
- ✓ Further research is needed to expand the domain knowledge of CLIME and adapt the system to other areas of law
- ✓ The development of more advanced natural language processing capabilities is crucial to improving the accuracy and effectiveness of legal advisory systems like CLIME.
