ABSTRACT
In most information retrieval systems, updates to indexed documents are handled by either adding the new document to the index and incrementing a version field, or by completely replacing the old version by the new version. These approaches work well when the entire document text is updated, but are insufficient to appropriately handle partial updates in amendments that explicitly state what changes are made to legal contracts. We propose here an approach that parses contract amendments to understand how the amendment is altering the original contract and determine the new effective legal contract. This approach uses semantic modeling and rules to indicate the effective contract to information retrieval systems.

Legal document assembly system for introducing law students with legal drafting
AbstractIn this paper, we present a method for introducing law students to the writing of legal documents. The method uses a machine-readable representation of the legal knowledge to support document assembly and to help the students to understand how the ...
Perspectives on reuse process support systems for document-type knowledge
HCI'07: Proceedings of the 12th international conference on Human-computer interaction: applications and servicesReusing documents as intellectual assets is one way of improving productivity and quality of products and services. The reuse process is well-known to make effective use of document-type intellectual assets and consists of four parts: (1) collecting and ...
