Abstract. In many domains concept definitions undergo change on a relatively frequent basis. Especially in law, such changes can have far reaching consequences. Existing ontology versioning techniques often do not consider that old and new definitions may need to co-exist side by side in a knowledge base, or they require non-standard language extensions. In this paper we present a description logic based representation that allows us to model and switch between varying definitions of concepts in a single OWL ontology. We show how this representation can be used to model complex versioning schemes in law. 1

An n-ary Language for Representing Narrative Information on the Web

Abstract. In this paper, we evoke first the ubiquity and the importance of the so-called ‘narrative ’ information, showing that the usual ontological tools, both the ‘traditional ’ and the ‘Semantic Web ’ ones, are unable to offer complete and reliable solutions for representing and exploiting this type of information. We supply then some details about NKRL (Narrative Knowledge Representation Language), a knowledge representation and inferencing environment especially created for an ‘intelligent ’ exploitation of narrative knowledge. 1

The CONCERTO project is concerned with the creation and management of knowledge repositories. The distinctive approach is to maintain an association between the textual form in which knowledge is expressed in source documents, and an expressive narrative knowledge representation language that supports inference and query operations. We first situate the CONCERTO approach in relation to current principles of knowledge management, before exploring three aspects of the mechanisms that CONCERTO supports: document management, acquisition of knowledge from text, and annotation base management. The concluding section gives an insight into how these mechanisms are being translated into changing working practices in a knowledge-based organisation within the CONCERTO consortium. 1 Principles of Knowledge Management In recent years, knowledge management has come to prominence as a topic of major concern for organisations (Davenport & Prusak, 1998). However, it is only very recently that academic discussion has moved towards practical implementation on the large scale,

Most of the thrust in the semantic web movement comes from the observation that existing NLP tools are not sophisticated or efficient enough to process the full richness of Natural Language, and therefore Machine Understandable annotations need to be added to Web Resources in order to make them accessible by remote agents. However, when the target application is not required to handle a huge amount of documents, but more limited sets, it is conceivable and practical to take advantage of NLP tools to pre-process textual documents in order to generate annotations (to be verified by human editors). We discuss an approach based on a combination of various Natural Language Processing techniques that addresses this issue. Documents are analized fully automatically and converted into a semantic annotation, which can then be stored together with the original documents. It is this annotation that constitutes the machine understandable resource that remote agents can query. 1.

Strategic decision making, especially in the areas of business intelligence and competitive intelligence, requires the acquisition of decision-relevant information pieces like market trends, fusions and company values. This information is extracted by pre-processing and querying multiple sources, combining and condensing the findings. It is characteristic that the extraction process is resource intensive and has to be performed regularly and quite frequently. In the research project PARMENIDES, we are developing methods that establish ontologies over an application domain, annotate documents with the ontology components and identify the entities in them, so that we can decompose business into conventional queries towards entities and XML-annotated texts.

We suggest that it could be possible to come closer to the Semantic Web goals by using `semantic annotations' that enhance the traditional ontology paradigm by supplementing the ontologies of concepts with `ontologies of events'. We present then some of the properties of NKRL (Narrative Knowledge Representation Language), a conceptual modeling formalism that makes use of ontologies of events to annotate in great detail those `narratives' that represent a very large percentage of the global Web information.

. In this paper, we introduce some of the data structures proper to NKRL (Narrative Knowledge Representation Language), a language expressly designed for representing, in a standardised way (metadata), the semantic content (the `meaning') of complex multimedia documents. We will emphasise, in particular, some characteristics of the new version of NKRL, implemented in Java and XML/RDF compliant. RDF (Resource Description Format) is a proposal for defining and processing World Wide Web metadata that is developed by a specific W3C Working Group (W3C = World Wide Web Consortium). 1

Abstract. A definitional change is one of the common ways in which legal ontologies can be amended. A revision of the meaning of a term in a model of legislation entails different classification of individuals, and thus affects knowledge about the domain and possibly the set of normative consequences implied by the model. In the paper we propose and discuss a description logic based representation that allows modeling and switching between different definitional variants of concepts used in an ontology. 1
