2011 2011 Aerospace Conference  
Our demonstration system infers the possibility of a terrorist plot by extracting key events and relationships from a collection of news articles and intelligence reports.  ...  Within this semantic environment, extractions are woven into the contextual fabric of a userprovided, domain-centric ontology where users together with user-provided logic can analyze these extractions  ...  A characteristic OWL execution platform consists of a triple-store where model content is persisted, a reasoner capable of inferring additional concepts based on embedded and externalized logic, and a  ...

OCD Dolores - Recovering Logical Structures for Dummies

Jean-Luc Bloechle, Maurizio Rigamonti, Rolf Ingold
2012 2012 10th IAPR International Workshop on Document Analysis Systems  
This paper presents OCD Dolores, an environment that aims at recovering the logical structures from documents by interactively inferring their models.  ...  The relevance of our restructuring system is assessed through a deep evaluation of Dolores' logical labeling capacities.  ...  Finally, the fourth and fifth documents are only used to observe the performance of the document model by looking at the classification matrices and recognition rates.  ...

Intuitionistic partition based conceptual granulation topic-term modeling

D. Malathi, S. Valarmathy
2014 Applied Mathematical Sciences  
Document Analysis represented in vector space model is often used in information retrieval, topic analysis, and automatic classification.  ...  A preprocessing of documents with intuitionistic fuzzy sets results in efficient classification of large corpus. But it depends on the datasets chosen.  ...  The Latent Dirichlet Allocation (LDA) model [1] , is another probabilistic approach which ties the parameters of all documents through hierarchical generative model.  ...

Marcius Armada de Oliveira, Kate Revoredo, José Eduardo Ochoa Luna, Fábio Gagliardi Cozman
2013 Joint Seminar on Ontology Research in Brazil / International Workshop on Metamodels, Ontologies and Semantic Technologies  
Link prediction in a network is mostly based on information about the neighborhood topology of the nodes.  ...  We empirically evaluate this proposal analyzing the assertion role of these individuals when predicting a link through a probabilistic ontology.  ...  The semantics of CRALC is based on probability measures over the space of interpretations, for a fixed domain.  ...

A Comparative Study of Ontology Languages and Tools [chapter]

Xiaomeng Su, Lars Ilebrekke
2002 Lecture Notes in Computer Science  
There are many languages and tools for constructing ontologies. In this paper we survey and compare different ontology languages and tools by the aid of an evaluation framework.  ...  Ontology attracts many attentions nowadays in computer science, largely because of the envision of semantic web, where real "semantic" of the web lies in ontology.  ...  F-Logic and OIL provide sound and complete inference and automatic classification are supported only by OIL and LOOM (due to their root in description logic).  ...
