Building and maintaining ontologies: a set of algorithms

Intelligent Analysis of Incomplete Data for Buildingformalontologies

“…dependencies between objects properties. The common models of typical types of dependencies between properties are proposed in [15] in the form of binary relations "existence constraints". In particular, a pair of properties m j , m k ∈ M, j ≠ k for any KD object (and hence ∀g i ∈ G * ) can be:…”

“…We note that for such dependencies the object of learning sample can have only a normal subset of the set's measured properties [15,16]. A subset of the measured properties Z ⊆ M is normal iff it is closed and compatible: Z is closed if it contains all of the properties conditioned by any element of Z, i.e.…”

Role of Semantic Web in the Changing Context of Enterprise Collaboration

“…Ontology: An ontology is considered as the backbone of the semantic web and the keystone for the web's automated tasks such as searching, merging, sharing, maintaining, customizing, and monitoring. It is used for defining the semantics present in the concerned domain and for sharing them among people, databases and applications (Lammari, Métais 2004). It is used to provide machine processable semantics for data and information sources that can be used by an agent (software or human), application or other information resources.…”

“…With the support of an ontology, a user can communicate with the system by developing and sharing a terminology for building knowledge bases for particular domains. Due to its strong implications in conception of reality, it has gained much interest in artificial intelligence for defining the basic terms and relationships using the vocabulary of a topic area as well as the rules for combining terms and relations to define extensions to the vocabulary (Lammari, Métais 2004). An ontology is developed and used for one or all of the following purposes:…”

CITOM: Incremental Construction of Topic Maps

“…In CITOM, the integration process builds on the work of our team on merging ontologies [38] and conceptual schemas [88]. It takes into account the multilingual nature of our Topic Map.…”
