Abstract. On-Line Analytical Processing (OLAP) is a data analysis approach to support decision-making. On top of that, Exploratory OLAP is a novel initiative for the convergence of OLAP and the Semantic Web (SW) that enables the use of OLAP techniques on SW data. Moreover, OLAP approaches exploit different metadata artifacts (e.g., queries) to assist users with the analysis. However, modeling and sharing of most of these artifacts are typically overlooked. Thus, in this paper we focus on the query metadata artifact in the Exploratory OLAP context and propose an RDF-based vocabulary for its representation, sharing, and reuse on the SW. As OLAP is based on the underlying multidimensional (MD) data model we denote such queries as MD queries and define SM4MQ: A Semantic Model for Multidimensional Queries. Furthermore, we propose a method to automate the exploitation of queries by means of SPARQL. We apply the method to a use case of transforming queries from SM4MQ to a vector representation. For the use case, we developed the prototype and performed an evaluation that shows how our approach can significantly ease and support user assistance such as query recommendation.

Abstract. The research shows results of a medical and legal assessment on teachers rights of implementation to health and safe work during remote work. The driver of the transition to telecommuting was the COVID-19 pandemic; the urgency of distancing resulted in an increase in professional risks, a decrease in the quality of work and life of teachers. A survey was carried out of 436 respondents from 22 constituent entities of the Russian Federation in order to develop proposals for improving the legislation and organizing the protection of the health of teachers on the basis of studying their opinions. The data obtained by the authors confirm the hypothesis put forward by them about the insufficiency of legal regulation of remote work and the protection of workers' health, the unpreparedness of workers to self-regulation of the quality of work. It leads to the conclusions about the need to strengthen the role of the state in the regulation of teachers work and to ensure the protective function of labor law in terms of protecting the health of teleworkers, as well as a qualitative change in the normative regulation of preventive medical examinations of teachers.
