Embodiments relate to systems and methods that improve the definition of semantic domains within incoming data, and accurately distribute data over those defined domains. In a particular embodiment, company-specific terminology and data governance (d.g.) domains are used to define “highly semantically loaded” terms within an incoming linguistic data corpus having existing semantic domains assigned thereto. Analyzing distribution patterns of such highly semantically loaded terms across the incoming linguistic data (and/or across the d.g. domains) enhances the accuracy of assignment of semantical domains and distribution of the data across these domains. Such improved semantic domains can improve operation of computers tasked with downstream processing of the linguistic data—e.g., by Natural Language Processing (NLP).
