In SAR interferometry, the data acquired by satellite are large. The points in the dataset are usually expressed in spatial-temporal dimension in which many epochs may be included. Extra information including contextual values and data from other sources sometimes are important to be taken into account when analyzing the deformation based on the...

Most queries in a collection of queries, also called a query workload, to some degree have parts of their intermediate execution steps in common. These intermediate exe- cution steps, also called subexpressions, provide the opportunity to further optimize query workload execution in addition to the already existing query optimization done by the...

With the increasing popularity of mobile and voice-assisted, extracting short and precise answer passages to open-domain questions is becoming an increasingly important information retrieval (IR) task. The recently released large-scale corpus for answer passage retrieval—WikiPassageQA—was shown to be challenging for both traditional retrieval...

The skyline operator has been proposed to bridge the gap between traditional and multimedia database systems by finding the optimal objects according to the notion of Pareto dominance. According to the notion of Pareto dominance an object dominates another if it is better in one attribute and equal in all others. Skyline sets end up being pretty...

In this thesis, we focus on database query processing for so-called experience items, i.e., items commonly encountered in E-Commerce systems such as books, games or movies which are better described by their perceived subjective consumption experience, or Perceptual Features, than by factual meta-data normally used in SQL-style queries. To...

Large volumes of data are produced, published and exchanged over the Internet. Such data is often in a semi-structured format which is typically irregular and therefore challenging to analyze. High-level data analysis languages are built on top of implicit parallel data processing platforms that handle distribution of computations and data....

I propose an implementation of the quantum private query protocol as described in an article using a photon to encode a question and reflectionor transmission of the photon as answer options. Each question is represented by a photon in a transmission line with both ends returning to the user, and the answer is represented by reflection or...

One of the standard features of today’s major Web search engines are query suggestions, which aid the user in the formulation of their search queries. Over the years, a number of different approaches have been proposed that have com- monly been evaluated in the standard Web search setting. In this thesis, we build a query suggestion pipeline...

With the decrease in cost of storage and computation of public clouds, even small and medium enterprises (SMEs) are able to process large amounts of data. This causes businesses to increase the amounts of data they collect, to sizes that are difficult for traditional database management systems to handle. Distributed SQL Query Engines (DSQEs),...

Mobile search has been a target of research for many years as it is challenging, multi-level and rapidly increasing in use, much like the mobile platforms themselves. This work examines the aforementioned subject from two of its aspects; mobile re-finding behaviour and queries' contextual information. Re-finding behaviour is an well-known...

Coaches are using video analysis to evaluate the performance of a team in field hockey. Events with the ball are tagged and saved in a match annotation file, which is used to lookup video fragments. The match annotation enables a coach to lookup and to evaluate single moments of the match but doesn't provide a coach insight in the tactic. Tactic...

Efficient querying and retrieval of data from XML databases is a challenging task, especially when these DBs contain a large number of documents, potentially millions of them. One way to scale out is by spreading the documents over multiple nodes, but running all queries on all nodes has poor scale-out qualities. Here we propose a solution to...

Static analysis techniques provide a means to detect software errors early in the development process, without actually having to run the software that is being analyzed. These techniques are common for statically typed languages and have found their way into IDEs such as Eclipse and Visual Studio. However, applying the same techniques to...

Patent collection is increasing incrementally. Most of the new technological information is from patent documents, and retrieving specific patents in such a large pool of documents has become a challenging issue for both patent examiners and normal/inexperienced users. Nowadays, most of the retrieval systems (patent retrieval systems) search for...

Detecting and tracking of objects by a tracking device can be considered a breach of privacy when an unauthorised party can associate certain tracking information outputted by the tracker to the identity of an individual. Therefore, when this privacy-sensitive information is stored in a database, it is desired that this is done in a secure...
