摘要： This invention provides a method for ranking contextual data of a plurality of data packages in a Knowledge Management System (KMS) as a computer system configured to store information on the maintenance of an apparatus, wherein each data package of the plurality of data packages includes a data part relating to maintenance of the apparatus, a first metadata part for the data part having a first metadata value and representing a first contextual information type and a second metadata part for the data part having a second metadata value and representing a second contextual information type, the method comprising the steps of: receiving a first and second relevance value for the first and second contextual information type respectively for a first data package, wherein the first and second relevance values represent the relevance of the first and second contextual information types of the first data part to the maintenance of the apparatus; receiving a third and fourth relevance value for the first and second contextual information type respectively for a second data package, wherein the third and fourth relevance values represent the relevance of the first and second contextual information types of the second data part to the maintenance of the apparatus; determining a first ranking value for the first contextual information type based on the first and third relevance values; determining a second ranking value for the second contextual information type based on the second and fourth relevance values; and storing the first and second ranking values in the KMS. The present invention also provides a method for retrieving data packages, including the steps of: receiving a data package request including a first metadata value for the first contextual information type and a second metadata value for the second contextual information type; and retrieving a first data package of the plurality of data packages based on at least one of the first and second metadata values of the data package request, the first and second ranking values, and at least one of the first and second metadata values of each data package of the plurality of data packages.
