Abstract:
Digital preservation is an active area of research, and recent years have brought forward an increasing number of characterisation tools for the object-level analysis of digital content. However, there is a profound lack of objective, standardised and comparable metrics and benchmark collections to enable experimentation and validation of these tools. While fields such as Information Retrieval have for decades been able to rely on benchmark collections annotated with ground truth to enable systematic improvement of algorithms and systems along objective metrics, the digital preservation field is yet unable to provide the necessary ground truth for such benchmarks. Objective indicators, however, are the key enabler for quantitative experimentation and innovation.
This paper presents a systematic model-driven benchmark generation framework that aims to provide realistic approximations of real-world digital information collections with fully known ground truth that enables systematic quantitative experimentation, measurement and improvement against objective indicators. We describe the key motivation and idea behind the framework, outline the technological building blocks, and discuss results of the generation of pagebased and hierarchical documents from a ground truth model. Based on a discussion of the benefits and challenges of the approach, we outline future work.
