The present invention is a method or system of analyzing items to create a data structure using lexicon analysis and filtering process. The present invention drives the analysis without a user being required to provide search terms and Boolean queries. Further, the present invention merges the use of unstructured data and structured data using a lexicon as a focus. Structured data is mapped to lexicon terms through one analysis process, while unstructured data is mapped to lexicon terms through a separate analysis process. In some disclosed embodiments, the mapping process uses a tuple structure of the source data to match with lexicon terms. The result is an analysis that merges the two different sets of data, which enables a user to navigate through the items using lexicons. Analysis results are displayed simultaneously in a tabular view, geospatial view, and lexicon histogram.
