Navigation among concepts in a free-form data object may be facilitated by using a text-mining tool to identify concepts in a free-form data object, with each concept having at least one concept instance. Using the identified concepts, a concept-navigable structure for the free-form data object may be generated. The concept-navigable structure may include links for navigating among concept instances and/or for jumping directly to a specific concept instance within the free-form data object.
