Abstract: Remote sensing information services classification ontology is a basic component for description,management,querying and searching of remote sensing information services on a semantic level in distributed Web environment.How to build the classification ontology is an important problem.We first analyze domain features of remote sensing information services and event-noun characteristic of their concepts.Based on that,we combine frame semantics theory to analyze semantic features of service concepts,and present an approach based on event frame and formal concept analysis to build the classification ontology.Experimental results show that this method is effective.
