Aspects described herein may relate to methods, systems, and apparatuses that process one or more tags associated with a dataset and index the dataset based on the processing of the one or more tags. Processing a tag may include, for example, tokenizing the tag, mapping or expanding abbreviations included within the tag, and otherwise mapping or expanding elements of the tag based on alphanumeric characteristics. Additionally, as part of processing the tag, a number of potential tags may be determined. An ontology may be searched to determine whether any of the potential tags are also found within the ontology. The dataset may be indexed into a searchable index based on any of the potential tags that are found within the ontology.
