This article addresses the problem of matching the most similar data objects to a given query
object. We adopt a generic model of similarity that involves the domain of objects and metric …

After two decades of research, the techniques for efficient similarity search in metric spaces
have combined virtually all the available tricks resulting in many structural index designs. As …

In order to speed up similarity query evaluation, index structures divide the target dataset
into subsets aimed at finding the answer without examining the entire dataset. As the …

With the arrival of Data Lakes (DL) there is an increasing need for efficient dataset
classification to support data analysis and information retrieval. Our goal is to use meta …

Since the introduction of the M-tree, a fundamental tree-based data structure for indexing
multi-dimensional information, several structural enhancements have been proposed. One …

Constant technological advances in electronic devices have led to the growth of elaborated
data such as large texts, time series, georeferenced imagery, genetic sequences, photos …

In this paper, we compare eight different multimedia exploration methods. We describe each
of them individually and evaluate their effectiveness in a user study focusing on different …

The exponential growth of multimedia data challenges effectiveness and efficiency of the
state-of-the-art retrieval techniques. In this thesis, we focus on browsing of large datasets …

Effective analysis, searching and browsing throughout arbitrary multimedia collections is still
a challenging task. To perform a search among multimedia objects, first, a similarity model …

This work is focusing on exploration of multimedia collections. It describes the problematic of
exploration and proposes new approaches to it, two based on the data structure M-Index …
