Robust and Scalable Content-and-Structure Indexing (Extended Version)
Kevin Wellenzohn, Michael H. Böhlen, Sven Helmer +2
Frequent queries on semi-structured hierarchical data are Content-and-Structure (CAS) queries that filter data items based on their location in the hierarchical structure and their…
Structural Textile Pattern Recognition and Processing Based on Hypergraphs
Vuong M. Ngo, Sven Helmer, Nhien-An Le-Khac +1
The humanities, like many other areas of society, are currently undergoing major changes in the wake of digital transformation. However, in order to make collection of digitised ma…
Cache-Efficient Sweeping-Based Interval Joins for Extended Allen Relation Predicates (Extended Version)
Danila Piatov, Sven Helmer, Anton Dignös +1
We develop a family of efficient plane-sweeping interval join algorithms that can evaluate a wide range of interval predicates such as Allen's relationships and parameterized relat…
Dynamic Interleaving of Content and Structure for Robust Indexing of Semi-Structured Hierarchical Data (Extended Version)
Kevin Wellenzohn, Michael H. Böhlen, Sven Helmer
We propose a robust index for semi-structured hierarchical data that supports content-and-structure (CAS) queries specified by path and value predicates. At the heart of our approa…
A Similarity Measure for Weaving Patterns in Textiles
Sven Helmer, Vuong M. Ngo
We propose a novel approach for measuring the similarity between weaving patterns that can provide similarity-based search functionality for textile archives. We represent textile…
