Problems solved by technology

[0005] The purpose of the present invention is to provide a conversion method from XBRL data to OWL data based on semantics, aiming at solving the problem that the existing technology cannot realize the conversion of data format at the semantic level, and needs to establish the mapping relationship between different taxonomy standards and the need to establish multiple A data conversion template greatly increases the difficulty of massive XBRL data management and query

Abstract

The invention discloses a method for converting XBRL data into OWL data based on semantics. The method for converting the XBRL data into the OWL data based on semantics includes the steps that based on the semantic net technology, an XBRL financial report and fact data semantic meta model is established, an XBRL classification standard is analyzed to establish an XML information set, an XBRL instance document is analyzed to establish an instance document information set, a conversion algorithm from the XBRL classification standard to OWL ontology is designed, and a conversion algorithm from the XBRL instance document to the OWL ontology is designed. Data formats can be converted on the semantic level, and the mapping problem of XBRL semantic heterogeneity is solved.

Description

technical field [0001] The invention belongs to the technical fields of XBRL technology and accounting informatization, and in particular relates to a conversion method from XBRL data to OWL data based on semantics. Background technique [0002] Extensible Business Reporting Language (eXtensible Business Reporting Language, XBRL) is the application of XML markup language in the field of business reporting. Since its birth in 1998, it has undergone continuous development and improvement. technical standards in the field. XBRL inherits the advantages of XML such as flexibility, extensibility and cross-platform, makes full use of technologies such as XML namespace, SCHEMA, XLink and XPath, and realizes the marking and marking of financial report concepts, the relationship between concepts and fact data. modeling. XBRL adopts a flat data structure, defines the concept of financial reporting in the Schema file, and defines the relationship between concepts in the link library f...
