1. A method for generating a provenance for a physical object, the method comprising: a computer identifying a first source of information that includes unstructured text and one or more keywords associated with an object; the computer retrieving the unstructured text included in the first source; the computer identifying provenance information of the object that is included in one or more segments of the unstructured text, wherein the identified provenance information is verified; the computer adding the identified provenance information of the object to a timeline; the computer receiving a purported provenance information; the computer determining a degree of accuracy of the purported provenance information using a statistical analysis based, at least in part, on a number of occurrences of the purported provenance information in the identified provenance information and a source of the purported provenance information, wherein the source of the purported provenance information comprises a historical context and one or more characteristics of a seller of the physical object; and in response to determining the degree of accuracy, the computer generating a report, wherein the report compares the purported provenance information to the identified provenance information, and wherein the report comprises (i) the degree of accuracy of the purported provenance information and (ii) an overlap between the purported provenance information and the identified provenance information.
