The digital library evaluation field has an evolving nature and it is characterized by a noteworthy proclivity to enfold various methodological orientations. Given the fact that the scientific literature in the specific domain is vast, researchers require tools that will exhibit either commonly acceptable practices, or areas for further investigation.

Evaluation is a vital research area in the digital library domain, demonstrating a growing literature in conference and journal papers. In this poster we present the research trends that governed the field within the decade 2001--2010 in the JCDL and ECDL conferences. The DL evaluation literature was annotated using the domain ontology DiLEO, which defines(More)
The literature is annotated using a domain ontology, named DiLEO, which defines explicitly the main concepts of the digital library evaluation domain and their correlations. The ontology instances constitute a semantic network that enables the uniform and formal representation of the critical evaluation constructs in both conferences, untangles their(More)
The social media revolution is having a dramatic effect on the world of scientific publication. Scientists now publish their research interests, theories and outcomes across numerous channels, including personal blogs and other thematic web spaces where ideas, activities and partial results are discussed. Accordingly, information systems that facilitate(More)
The multidimensional nature of digital libraries evaluation domain and the amount of scientific production published on the field hinders and disorientates the interested researchers who contemplate to focus on the specific domain. These communities need guidance in order to exploit the considerable amount of data and the diversity of methods effectively as(More)
The multidimensional nature of digital libraries evaluation domain poses several challenges to the research communities that intend to assess criteria, methods, products and tools, and also practice them. The amount of scientific production that is published in the domain hinders and disorientates the interested researchers. These researchers need guidance(More)
