Ontology-based topological representation of remote-sensing images

Rafael Oliva-Santos, Francisco Maciá-Pérez, Eduardo Garea-Llano
2013 International Journal of Remote Sensing  
This representation has been validated by a case study of semantic retrieval based on the Normalised Vegetation Index (NDVI), taking into account the topological relations between NDVI regions in images  ...  This representation can be used to develop applications in Geospatial Semantic Web.  ...  Furthermore, the overall use of ontologies in our proposal allows for the explicit definition of both the objects and the organising data structure, resulting in an improved semantic analysis.  ...

A Concept-Centered Hypertext Approach to Case-Based Retrieval [article]

Stefano Marchesin
2018 arXiv   pre-print
We propose a research that aims at improving the effectiveness of case-based retrieval systems through the use of automatically created document-level semantic networks.  ...  Mining concepts and relations from text, information extraction techniques represent the core of the document-level semantic networks' building process.  ...  Concept-based methods can be categorized in two types: (i) methods that use concepts throughout the entire process, in both indexing and retrieval stages [11] , and (ii) methods that apply concept analysis  ...

A query expansion method for retrieving online BIM resources based on Industry Foundation Classes

Ge Gao, Yu-Shen Liu, Meng Wang, Ming Gu, Jun-Hai Yong
2015 Automation in Construction  
Keyword-based search methods have been widely used due to their ease of use, but their search accuracy is often not satisfactory because of the semantic ambiguity of terminologies in BIM-specific documents  ...  Secondly, by combining the ontology and local context analysis technique, an automatic query expansion method is presented for improving retrieval performance.  ...  Existing explicit approaches such as ontology-based query expansion [18] , semantic indexing [19] , explicit semantic analysis (ESA) [20] and granularity analysis [21] have been developed for improving  ...

Anwendung der Konzeptanalyse und ontologische Modellierung in der Wirtschaftsinformatik: Vorwort [chapter]

Heinz Dreher, Torsten Reiners, Stefan Voß, Robert Williams
2010 Multikonferenz Wirtschaftsinformatik 2010  
One popular approach for progressing issues relating to concept 'understanding' being used in recent times is ontology based.  ...  Ontologies are an explicit, formal specification of common conceptual classification schemes and generally describe a hierarchy of concepts using a subsumption relation.  ...  For this task concepts are retrieved, which are used to get a summary of the learning subject for the purpose of matching those concepts against a specific essay for use in marking.  ...
