Integrating instance-level and attribute-level knowledge into document clustering

Jinlong Wang, Shunyao Wu, Gang Li, Zhe Wei
2011 Computer Science and Information Systems  
In this paper, we present a document clustering framework incorporating instance-level knowledge in the form of pairwise constraints and attribute-level knowledge in the form of keyphrases.  ...  finally evaluate and select clustering result based on the degree of users' satisfaction.  ...  In this paper, we aim to integrate both the instance-level knowledge in the form of pairwise constraints and the attribute-level knowledge in the form of keyphrases to assist document clustering.  ...

Learning of Ontologies from the Web: the Analysis of Existent Approaches

Borys Omelayenko
2001 International Conference on Database Theory  
The next generation of the Web, called Semantic Web, has to improve the Web with semantic (ontological) page annotations to enable knowledge-level querying and searches.  ...  We consider three components of the query processing system: natural language ontologies, domain ontologies and ontology instances.  ...  Acknowledgements The author would like to thank Dieter Fensel for helpful discussions and comments, and Heiner Stuckenschmidt and four anonymous reviewers for their comments.  ...

Combining schema and instance information for integrating heterogeneous data sources

Huimin Zhao, Sudha Ram
2007 Data & Knowledge Engineering  
Cluster analysis techniques are used first to identify similar schema elements (i.e., relations and attributes).  ...  We propose an iterative procedure for detecting both schema-level and instance-level correspondences from heterogeneous data sources.  ...  Note that the above-mentioned steps for identifying schema-level and instance-level semantic correspondences can be streamlined with schema integration [36] and instance integration steps to build the  ...

An XML-Based Interorganizational Knowledge Mediation Scheme to Support B2B Solutions [chapter]

S. Castano, V. De Antonellis, S. De Capitani di Vimercati
2003 IFIP Advances in Information and Communication Technology  
The proposed IKMS is a set of mediated descriptions of exchange information at the global level, defined as global X-classes, and relies on a set of techniques for building such global X-classes.  ...  We propose an Interorganizational Knowledge Mediation Scheme (IKMS) acting as an information infrastructure for B2B solutions for aggregating exchange information supplied by the companies participating  ...  properties and attributes (cluster reconciliation step).  ...

An Information Retrieval System with Cooperative Behaviour

Paulo Quaresma, Irene Pimenta Rodrigues
1999 Nordic Conference of Computational Linguistics  
Cooperation is achieved through two main strategies: 1) clustering the answer sets of documents accordingly with the domain and IR-level knowledge; 2) keeping the context of the interaction and inferring  ...  The information retrieval level includes knowledge about IR actions over sets of documents. The text level has knowledge about the words in each text.  ...  Our clustering method is based on the Scatter/Gather browsing paradigm that clusters documents into topically-coherent groups.  ...

A Semantic Approach to XML-based Data Integration [chapter]

Patricia RodrÌguez-Gianolli, John Mylopoulos
2001 Lecture Notes in Computer Science  
The paper describes a prototype tool, named DIXSE, which supports the integration of XML Document Type Definitions (DTDs) into a common conceptual schema.  ...  These wrappers are used to populate the common conceptual schema thereby achieving data integration for XML documents.  ...  Acknowledgements This research was partly funded by the Natural Sciences and Engineering Research Council (NSERC) of Canada.  ...

Ontology-based integration for Sharing Knowledge over the Web

Devis Bianchini, Valeria De Antonellis
2004 International Workshop on Data Integration over the Web  
Our methodology generates an ontology organized into concepts and concept relationships at different levels of detail, to provide multiple, unified views of the datasources containing heterogeneous information  ...  In this paper, we propose a methodology developed in the framework of the VISPO project for engineering a three-layer ontology, based on the conceptualization, integration, synthesis and categorization  ...  Two concepts α and β are disjoint if the sets of their instances are disjoint, i.e., there exist an attribute x of α and an attribute y of β such that names of x and y are equal or synonyms and the types  ...

A Survey of Ontology Learning Approaches

Maryam Hazman, Samhaa R. El-Beltagy, Ahmed Rafea
2011 International Journal of Computer Applications  
Ontologies are the vehicle by which we can model and share the knowledge among various applications in a specific domain. So many research developed several ontology learning approaches and systems.  ...  The problem that ontology learning deals with is the knowledge acquisition bottleneck, that is to say the difficulty to actually model the knowledge relevant to the domain of interest.  ...  Finally, they mine the concept instances (members of concepts) and the values of the instance attributes in the same way as the sub taxonomy mining. Hazman et.al.  ...

Bridging abstraction layers in process mining

Thomas Baier, Jan Mendling, Mathias Weske
2014 Information Systems  
We use domain knowledge extracted from existing process documentation to semi-automatically match events and activities.  ...  While the maturity of process mining algorithms increases and more process mining tools enter the market, process mining projects still face the problem of different levels of abstraction when comparing  ...  Thus, in most cases we face a 1:n mapping on instance level and event instances will be clustered to activity instances.  ...

Bottom-Up Extraction and Trust-Based Refinement of Ontology Metadata

Paolo Ceravolo, Ernesto Damiani, Marco Viviani
2007 IEEE Transactions on Knowledge and Data Engineering  
We present a way of building ontologies that proceeds in a bottom-up fashion, defining concepts as clusters of concrete XML objects.  ...  Our rough bottom-up ontologies are based on simple relations like association and inheritance, as well as on value restrictions, and can be used to enrich and update existing upper ontologies.  ...  A concept lattice can be obtained evaluating two functions: f and g. Function f maps a set of documents into the set of common attributes, whereas g does the same for attribute sets.  ...
