Shape Comparison - Shape Analysis - Object Mining: Projects of the 3D lab

Since the establishment of the 3D campus lab in October 2016, more than 200 plaster casts of the 
archaeological collections have been digitized using a structured light scanner. The paper will discuss the
advantages and challenges of 3d digitizers for archaeological and art historical research. We have, for example, examined how accurately our plaster casts reproduce the cast originals and how
 closely sculpted architectural ornamentations resemble each other in shape. Roman sculpture worked
heavily with copies of Greek originals, and even imperial portraits were produced using a copying process.
A more precise comparison of 3D scans now makes it possible to grasp these processes even more
accurately and analyze them in terms of the relevant factors of ancient perception. In addition to precise shape comparisons, an important role is played by the categorization of similarity
(and hence culturally shaped concepts of similarity). Archaeologists are faced with the problem that
similarities of shape can be asserted verbally, but cannot be adequately described in language.
More research using automated 3D shape recognition needs to be conducted into the distinctive
differentiation of formal dependencies between similar figures, as elaborated in the field of archaeology.
The ‘Schemata’ project aims both to develop procedures for creating corpora automatically by means of 3D
 pattern recognition (object mining) and to reflect on the related schematizations and their scientific uses
for IT and object sciences.

Russian Formalism in an African Dress – An Ontology of Southern African Folktales Mapped to Proppian Functions

Folk and Fairy tales are a substantial part of oral history. They play an important role in the cultural heritage of regions, nations or cultural minorities. In the European context, fairy tales have been collected and editored by the Grimm brothers in the beginning of the 19th century. In the African context, the oral tradition of folk tales exists up to this day. Presumably, African folk tales are therefore different from European fairy tales in terms of structure and motifs. This project aims to construct an ontology of African folk tales following the approach of Russian folklorist Vladimir Propp. It does not only collect and structure African folk tales, but also investigates how they follow Propp's formalism and how motifs and agents are verbalised.
