WossiDiA

This article sheds light on the digital transformation of Richard Wossidlo’s regional ethnographic and linguistic collection into the research environment WossiDiA. The Digital Wossidlo Archive is based on making handwritten sources and their indexing visible to users. It has been implemented as a hypergraph database, whose abundance of node and hyperedge types is suitable for representing the diversity and delicate nature of the tradition archive. This paper will discuss how proprietary properties have been preserved in the transformation process and how the digital collection is compatible with big data scenarios. Follow-up projects have contributed to this. “Efficiency,” the necessity of resource-saving, will also be problematized. Finally, it will be shown how a sparse ethnographic fieldnote can be enriched into a complex hypergraph extract, a method which is reminiscent of dragnet detection

The Hydra.PowerGraph System

Directed hypergraphs are known from graph theory 11 and are well understood within their own domain 7--9, 22, 23. This paper provides an overview on the expressiveness of directed and typed hypergraphs as a modeling paradigm not only for the content of digital libraries and archives but a variety of applications. Furthermore, hypergraphs are sufficiently expressive to provide an implementation logic for conceptual models like CIDOC/CRM 18 in the context of museum-related systems and digital archives

A Mobile Tourist Assistance and Recommendation System Based on Complex Networks

In recent years, the tourism assistance community is gradually shifting its emphasis to digital, interactive systems. Our project aims for digital tourism assistance by combining mobile guiding and route recommendation based on community networks. We use complex networks to tackle problems, such as deriving optimal routes in conjunction with knowledge deduced from our social tourist network, and giving a respectable prediction of which meta- and multimedia data about touristic objects are needed while the tourist is on tour. This article describes ongoing work on the recommendation system and mobile semantic replication strategies.
