SUMMARY
The paper deals with the current trends in the European Research Area (ERA) concerning openness, digitalization and evaluation in research in general and in the field of Social Sciences and Humanities (SSH) knowledge in particular. Prospects for the open science, open access to research results development in the context of the global COVID-19 pandemic are characterized; the pandemic proved the inevitability of rapid change due to the development of digital technologies. It was found out that the trend to assure open access dominates in the ERA, which is supported by the European Commission, European Association of Universities, European Federation of Academies of Sciences and Humanities, wide professional community through the Horizon Europe programme implementation. The basis of the digital technology platform for the implementation of a wide range of research processes (from providing access to cloud computing, storage and processing of large data sets to the research results exchange, etc.) is the European Open Science Cloud (EOSC). The EOSC portal implementation through the work of research infrastructures, that contribute to regional, national, European and global development, and e-infrastructures, which in the SSH are divided into relative components and have appropriate functional levels, is analyzed. It is proved that the problem of research presentation and evaluation is actualized in the process of its transition to open science; the SSH richness, diversity, interdisciplinarity, national context and stakeholders should be taken into account. The necessity of changes in the SSH researches’ evaluation and importance of the initiative to preserve and take into account their balanced multilingualism in the process of transition to open science are substantiated. It was found that the current Ukrainian regulations do not include such specifics. This significantly complicates research conduction, narrows the prospect of research results publishing due to the limited number of the SSH scientific professional journals in Ukraine, makes the training and attestation of young researchers difficult. In order to adequately respond to these challenges with the participation of the NAES of Ukraine researchers a complex of measures at the institutional and individual levels is proposed to systematically and consistently support the open science initiative.
