Firstly, this paper deduces the conception of metadata quality based on the research literatures about metadata quality. Then it summarizes the four main dimensions of the metadata quality assessment, which are completeness, accuracy, consistency and conformance to expectations. Moreover, automatic assessment of metadata quality is necessary in the digital resource environment by comparing with the assessment methods. It applies the theories, which include information entropy, vector space model and term frequency-inverse document frequency, to calculating the main four dimensions in order to implement the automatic quantitative assessment. Finally, this paper introduces the calculation methods of others assessment dimensions, and proposes that it is necessary to deeply research the metadata quality quantitative assessment.
