While a user is viewing content on a computer display, the universal data relationship inference engine presents related information from disparate data sources. A normalized index is maintained that indexes content to a set of standard taxonomy terms. The inference engine parses content being viewed by the user. If the content includes tags for some of the standard taxonomy terms, then the system may provide the user with the ability to view the related content that is indexed by the normalized index. If there are not taxonomy tags then the system may attempt to recognize non-standard taxonomy terms in the content in order to provide the user with related content. The inference engine may also identify related content by identifying synonyms to the taxonomy terms.
