We review the major paradigms for similarity queries, in particular those that allow approximate results. We propose an original classification schema which easily allows existing approaches to be compared along several independent coordinates, such as quality of results, error metrics, and user interaction.

There is a gap between software testing research and practice. One reason is the discrepancy between how testing research is reported and how testing challenges are perceived in industry. We propose the SERP-test taxonomy to structure information on testing interventions and practical testing challenges from a common perspective and thus bridge the communication gap. To develop the taxonomy we ...

Nowadays, the human-computer interaction is being a hot topic. In such a way, several methods have been proposed to deal with multi-granularity when people with different knowledge level express their preferences on the same concept using linguistic notation, that is, words instead of numbers. This is a critical problem in group decision making scenarios, but all the existing approaches have th...

This thesis attempts to describe the necessary steps to program an application to take pictures, organize and process them in order to generate and visualize a three-dimensional colored point cloud. The steps to create the application are explained, using the argumentative logic to every decision and fulfill the stated objective in the best possible way, balancing the available technology and t...

We consider the problem of making efficient qualitytime-cost trade-offs in collaborative crowdsourcing systems in which different skills from multiple workers need to be combined to complete a task. We propose CrowdAsm an approach which helps collaborative crowdsourcing systems determine how to combine the expertise of available workers to maximize the expected quality of results while minimizi...

Elektronické testovanie znalostí a faktory vplyvu na výsledky Didactic test in electronic version presents fast and precise, modern and effective form of feedback from students to teacher. Electronic test, as a highly formalised instrument of evaluation of the students' preparation and knowledge, has its own unique place in the whole education process. The contribution suggests on practical app...

Peer-to-peer systems have emerged as a popular way to share huge volumes of data. The usability of these systems depends on effective techniques to find and retrieve data; however, current techniques used in existing P2P systems are often very inefficient. In this paper, we present three techniques for efficient search in P2P systems. We present the design of these techniques, and then evaluate...
