Exploring multiple views of data sets can provide assistance on discovering unforeseen associations among their elements. Employing a coordination technique creates associations among elements across related views. Usually, the coordination process uses a mapping among data elements, that are constrained by using data attributes, which is a constraint to user exploration process (only linked data can be usually associated). In this work it is presented Semantic Coordination, a mechanism that applies ontologies to link data elements based on mappings provided by semantic. Representing the underlying data into ontology, the exploratory visualization can be benefited from a semantic representation to create the mappings, what might be helpful to establish associations on multiple views. Also, it is shown the results of two case studies applying the Semantic Coordination and traditional techniques on exploring text collections. The analysis of the obtained results, have shown the proposed coordination mechanism improves the exploration using multiple views, in comparison with traditional techniques
