Research on the Information Quality Measurement of Judicial Documents

This paper explores and defines data quality metrics of document data in judicial field. The objective information theory defines information as an objective reflection of the objects and the state of movement in the objective world and the subjective world. All kinds of information systems in physics can obtain, transmit, process and apply various objective information. Document is the carrier of case information, and the entity mapping of cases in the objective world. In order to describe the nature of the case information and its various dimensions accurately, this paper constructs and quantifies the data quality evaluation standards of the documents with the help of six-tuple information theory and the related knowledge of rough sets.
