BalOnSe: Temporal Aspects of Dance Movement and Its Ontological Representation

Abstract

In this paper we present BalOnSe (named after the ballet step balance), an ontology-based web interface that allows the user to annotate classical ballet videos, with a hierarchical domain specific vocabulary and provides an archival system for videos of dance. The interface integrates a hierarchical vocabulary based on classical ballet syllabus terminology (Ballet.owl) implemented as an OWL-2 ontology. BalOnSe supports the search and browsing of the multimedia content using metadata (title, dancer featured, etc.), and also implements the functionality of "searching by movement concepts", i.e., filtering the videos that are associated with particular required terms of the vocabulary, based on previous submitted annotations. In the paper, we present the ballet.owl ontology, and its structure, explaining the conceptual modeling decisions. We highlight the main functionality of the system and finally, we present how the manual ontology guided annotation allows the user to search the content through the vocabularies and also view statistics in the form of tag clouds.

Querying Log Data with Metric Temporal Logic

“…Based on these encouraging results, we plan to include our temporal OBDA framework into the Ontop platform (Rodriguez-Muro et al, 2013;Kontchakov, Rezk, Rodriguez-Muro, Xiao, & Zakharyaschev, 2014;Calvanese et al, 2017); visit http://ontop.inf.unibz.it/ for more information on Ontop. Note also that datalogMTL presented here has been recently used to develop an ontology of ballet moves (see Example 2) that underlies a search engine of annotated sequences in ballet videos (Raheb et al, 2017). This is a third use case for our framework (and we are aware of a few more emerging use cases), which makes an efficient and user-friendly implementation of the framework a top priority.…”

“…Example 2. We illustrate the importance of the operators S (since) and U (until) using an example inspired by the ballet moves ontology (Raheb, Mailis, Ryzhikov, Papapetrou, & Ioannidis, 2017). Suppose we want to say that SupportBending is a move spanning from the beginning to the end of RightAndLeftSupportLowPlace provided that it is preceded by RightAndLeftSupportMiddlePlace, which ends within 3s from the beginning of the RightAndLeftSupportLowPlace, as shown below:…”

Ontology–based access to temporal data with Ontop: A framework proposal

“…Initial experimental results obtained by Brandt et al (2018) demonstrated reasonably good performance and scalability on data from weather stations in the USA (of a size up to 8 GB) and turbine sensor data (of a size up to 6 GB). Another application of a similar formalism has been provided by El Raheb et al (2017) in the context of querying user annotated ballet movement videos. Practical ontology-mediated query answering with temporal ontologies based on the Halpern-Shoham interval temporal logic, HS (Halpern and Shoham, 1991) was investigated by Kontchakov et al (2016).…”

Conceptual and experiential dance languages
