A Hierarchical Clustering Method for Semantic Knowledge Bases
نویسندگان
چکیده
This work presents a clustering method which can be applied to relational knowledge bases. Namely, it can be used to discover interesting groupings of semantically annotated resources in a wide range of concept languages. The method exploits a novel dissimilarity measure that is based on the resource semantics w.r.t. a number of dimensions corresponding to a committee of features, represented by a group of concept descriptions (discriminating features). The algorithm is an adaptation of the classic Bisecting k-Means to complex representations typical of the ontology in the Semantic Web. We discuss its complexity and the potential applications to a variety of important tasks.

Hierarchical Fuzzy Clustering Semantics (HFCS) in Web Document for Discovering Latent Semantics
This paper discusses about the future of the World Wide Web development, called Semantic Web. Undoubtedly, Web service is one of the most important services on the Internet, which has had the greatest impact on the generalization of the Internet in human societies. Internet penetration has been an effective factor in growth of the volume of information on the Web. The massive growth of informat...
متن کاملClustering rule bases using ontology-based similarity measures
Rules are increasingly becoming an important form of knowledge representation on the Semantic Web. There are currently few methods that can ensure that the acquisition and management of rules can scale to the size of the Web. We previously developed methods to help manage large rule bases using syntactical analyses of rules. This approach did not incorporate semantics. As a result, rule categor...
متن کاملDocument Clustering with Explicit Semantic Analysis (ESA)
Document clustering recently became a vital approach as numbers of documents on web and on proprietary repositories are increased in unprecedented manner. The documents that are written in human language generally contain some context and usage of words mainly dependent upon the same context; recently researchers have attempted to enrich document representation via external knowledge base. This...
متن کاملUncertainty analysis of hierarchical granular structures for multi-granulation typical hesitant fuzzy approximation space
Hierarchical structures and uncertainty measures are two main aspects in granular computing, approximate reasoning and cognitive process. Typical hesitant fuzzy sets, as a prime extension of fuzzy sets, are more flexible to reflect the hesitance and ambiguity in knowledge representation and decision making. In this paper, we mainly investigate the hierarchical structures and uncertainty measure...
متن کاملVisualization of Medical Rule-based Knowledge Bases
In this work the topic of applying clustering as a knowledge extraction method from real-world data is discussed. The authors propose hierarchical clustering method and visualization technique for knowledge base representation in the context of medical knowledge bases for which data mining techniques are successfully employed and may resolve different problems. What is more, the authors analyze...
