Multilingual Natural Language Interaction with Semantic Web Knowledge Bases and Linked Open Data [chapter]

Mariana Damova, Dana Dannélls, Ramona Enache, Maria Mateva, Aarne Ranta
2014 Towards the Multilingual Semantic Web  
The approach builds on a semantic knowledge infrastructure in RDF, it is based on OWLIM-SE and the data integration method Reason-able View supplied with an ontological reference layer.  ...  This chapter is about a technique which allows interaction in natural language with semantic knowledge bases.  ...  It is based on the assumption that ontologies restricts the semantic queries that can be formulated over them.  ...

Pythia: Compositional Meaning Construction for Ontology-Based Question Answering on the Semantic Web [chapter]

Christina Unger, Philipp Cimiano
2011 Lecture Notes in Computer Science  
In this paper we present the ontology-based question answering system Pythia. It compositionally constructs meaning representations using a vocabulary aligned to the vocabulary of a given ontology.  ...  In doing so it relies on a deep linguistic analysis, which allows to construct formal queries even for complex natural language questions (e.g. involving quantification and superlatives).  ...  Introduction The growing Semantic Web provides a large amount of ontology-based semantic markup that question answering systems can exploit in order to interpret and answer natural language questions.  ...

Simplifying syntactic and semantic parsing of NL-based queries in advanced application domains

E. Kapetanios, D. Baer, P. Groenewoud
2005 Data & Knowledge Engineering  
The paper presents a high level query language (MDDQL) for databases, which relies on an ontology driven automaton.  ...  This is simulated by the human-computer interaction mode for the query construction process, which is driven by an inference engine operating upon a frames based ontology description.  ...  This also alleviates the task of providing the same real-world semantics in more than one natural language by simply replacing the values for names of the ontology elements.  ...

Semantic Image Annotation using Ontology And SPARQL

For representation, organization and retrieving of images, the searching approaches based on semantic provide effective and efficient results by using image ontology.  ...  They are used for annotations based on textual of the images.  ...  Semantic based search provides appropriate and relevant results than that of traditional keyword based search. The efficiency of semantic based search depends on the ontology [1].  ...

Ontology Design and Reuse with Conceptual Roles [chapter]

Jakob Henriksson, Michael Pradel, Steffen Zschaler, Jeff Z. Pan
2008 Lecture Notes in Computer Science  
We present role-based ontologies as an extension of standard ontologies and define their semantics through a reduction to standard Description Logics, such that existing reasoners can be used.  ...  As the use of ontologies becomes commonplace, they will be constructed more frequently and also become more complex.  ...  Formalization of Role-Based Ontologies We formalize role-based ontologies in three parts, based on the methodology described in Section 3. A base ontology only contains natural types.  ...
