Embodiment Construction

[0054] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] For a large number of media digital resources, their format information is one of the key factors for logical preservation. Monitoring format risks to determine when appropriate measures should be taken is a major task in the long-term preservation of digital resources. For this reason, the present invention proposes an effective risk quantification-based semi-automatic digital resource long-term storage format obsolescence risk assessment method. The method reduces manpower requirements and facilitates sharing and utilization of computer systems by reusing domain experience and knowledge about format obsolescence risks, and is applicable to large-scale resource processing in applications such as digital libraries and archi...

Abstract

The invention provides a digital resource long-term storage format outdating risk quantitative evaluation method, which comprises the following steps of: presetting an initial evaluation questionnaire; determining model parameters according to the questionnaire, and constructing and optimizing an evaluation model; and integrating the answer of each user according to the evaluation questionnaire, and calculating a format outdating risk value according to the evaluation model. The evaluation method reuses field experience and knowledge on the format outdating risk through field knowledge quantification, reduces manpower demand, and provides convenience for sharing computer systems and utilizing information resources so as to meet the requirement on large-scale resource processing in a digital library and an archive.

Description

technical field [0001] The invention relates to the field of digital resource management, in particular to a method for quantifying and evaluating the risk of digital resource long-term storage format obsolescence. Background technique [0002] The long-term preservation of digital resources is related to the long-term availability and permanent readability of precious digital information that records human activities, and with the continuous deepening of digitization and informatization, its importance and urgency have become increasingly apparent. At present, not only many countries regard the long-term preservation of digital resources as a strategic issue of the digital society supported by digital libraries, digital archives and other digital information systems, but also at the global level, the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the Storage Network Industry Alliance (SNIA) has also vigorously promoted work in this area.
