In this paper we present the approach for creating semantic metadata from relational database data. When building ontology-based information systems, it is often needed to convert or replicate data from existing information systems (such as databases) to the ontology based information systems, if we want the ontology-based systems to work with real data. RDB2Onto tool converts selected data fro...

We present the project aimed at creating a database of detailed architectural process models of memory-based decision models. Those models are implemented in the cognitive architecture ACT-R. In creating this database, we have identified commonalities and differences of various decision models in the literature. The model database can provide insights into the interrelation among decision model...

OBJECTIVE The purpose of this study was to index the contents of the pre-MEDLINE American Journal of Roentgenology into a database that could then be accessed over the World Wide Web. CONCLUSION The database is composed of more than 8,000 citations from the years 1914 (volume 1) to 1965 (volume 95). Using a Web browser, a user can search the database by year, volume, title word, page, or auth...

Emotions can be expressed in various ways. Music is one of possible media to express emotions. However, perception of music depends on many aspects and is very subjective. This paper focuses on collecting and labelling data for further experiments on discovering emotions in music audio files. The database of more than 300 songs was created and the data were labelled with adjectives. The whole c...

From image retrieval to image classification, all research shares one common requirement: a good image database to test or train the algorithms. In order to create a large database of images, we set up a project that allowed gathering a collection of more than 33000 photographs with keywords and tags from all over the world. This project was part of the “We Are All Photographers Now!” exhibitio...

We present a method for synthesizing fluid animation from a single image, using a fluid video database. The user inputs a target painting or photograph of a fluid scene along with its alpha matte that extracts the fluid region of interest in the scene. Our approach allows the user to generate a fluid animation from the input image and to enter a few additional commands about fluid orientation o...

SaaS (Software as a Service) paradigm brings both lots of benefits to end users and lots of problems to software developers. One of such problems is an implementation of a data storage which is able to satisfy needs of clients of a service provider, at the same time providing easy application interface for software developers and great opportunities for administration and scaling. This paper pr...

In the past decade, accelerometer sensors became small enough to embed in mobile devices that people are using every day. Thus, arm movements became attractive to control mobile games and game consoles. However, there is no widely-used gesture-vocabulary for controlling devices and gesture recognition is not standardized. Furthermore, there is no widely-accepted benchmark for measuring performa...
