Abstract
A system for joining modeled data with new data sources. Modeled tabular data containing categorical and metric data is received. New data containing structured or non-structured data is received. The new data is indexed and data clusters and/or data facets are identified. Data clusters and data facets are also identified within the received modeled data. A textual query from a user is received and semantically indexed into keywords. Data clusters and data facets within the new data are matched to the keywords in the indexed query. Data clusters and data facets within in the modeled data are matched to the keywords in the indexed query. A table is generated containing the modeled data and matching data clusters and data facets from the new data.
