We develop a family of efficient plane-sweeping interval join algorithms for evaluating a wide range of interval predicates such as Allen’s relationships and parameterized relationships. Our technique is based on a framework, components of which ca

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 value for some attribute. We propose the Robust and Scalable Content-

We develop a highly efficient access method, called Delta-Top-Index, to answer top- k subsequence matching queries over a multi-dimensional time series data set. Compared to a naive implementation, our index has a storage cost that is up to two order

Semi-structured data is prevalent and typically stored in formats like XML and JSON. The most common type of queries on such data are Content-and-Structure (CAS) queries, and a number of CAS indexes have been developed to speed up these queries. The

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 material in this area easily accessible, we often still lack adequate se

We discuss the trend towards using quantitative metrics for evaluating research. We claim that, rather than promoting meaningful research, purely metric-based research evaluation schemes potentially lead to a dystopian academic reality, leaving no sp

We propose a framework for building a decentralized electronic marketplace for computing resources. The idea is that anyone with spare capacities can offer them on this marketplace, opening up the cloud computing market to smaller players, thus creat

We enhance a tourist trip planning framework based on orienteering with category constraints by adding social sensing. This allows us to customize a user’s experience without putting the burden of preference elicitation on the user. We identify the

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 approach is a novel dynamic interleaving scheme that merges the path and val

We illustrate an application of social sensing for automatically customizing the solutions to orienteering problems with category constraints. The aim is to improve the user satisfaction in tourist trip planning provided by a previously developed eff
