Τεκμήριο Analysis of quantitative profiles of GI Education: towards an analytical basis for EduMapping(Springer Berlin Heidelberg, 2011) Rip, Frans; Grinias, Elias; Kotzinos, DimitrisThere is an ongoing discussion among the members of the GI educational community about the possibility to find a common way to describe a course taught as part of a GI curriculum (anywhere in the world) with the final goal of being able to automatically identify similar courses and define their equivalence. EduMapping is such an initiative that started recently, which used the BoK concepts as its basic labeling scheme. Based on this work we extended the analysis provided by the EduMapping initiative by suggesting and applying an analytical method that is capable of clustering the courses into classes based on (dis)similarity metrics, which are in turn calculated based on the course assessments done by their instructors using the BoK concepts. In this paper, we present and discuss the preliminary results obtained while applying the suggested method on the EduMapping data. We also provide some pointers for further research in an area that has very few contributions so far.Τεκμήριο On handling geographic data of paper and digital forms in academic libraries: the role of ontologies(2012) Theodoridou-Sotiriou, Lila; Kotzinos, Dimitris; Sotiriou, ZoeThe last few years the availability of geographic data in various formats in academic libraries is increasing, bringing back in the spotlight issues that might not have been the focus of library related research for the past few years. Moreover the diversity of the available formats those data can be in, ranging from old-fashioned paper maps to digital maps and from satellite images to digital cartographic data, increases the complexity of the problem at hand. All these data cannot be considered anymore out of scope for the libraries since they are tightly related with the rest of information maintained by them, especially in academic settings where they can have an impact both on teaching and research. On the other hand, the so called digital libraries initiatives have brought into the picture the wide use of ontologies and semantic models in order to facilitate the better understanding among the librarians, the users and the expanded possibilities of using the material itself. The focus of the work discussed in this paper is to analyze and present ontology based solutions that would allow academic libraries to combine current or future semantic based catalogues with ontologies that describe the spatial characteristics of such items. The tools to support such implementations become slowly but increasingly available and this makes its implementation more apparent for the academic libraries of the (near) future.
