Data Sources and Methodology of the 4th Edition of the Research.com Best Engineering and Technology Universities in Lithuania Ranking
The 4th edition of the Research.com Best Engineering and Technology Universities in Lithuania Ranking was developed through the integration of data from leading bibliometric repositories, including OpenAlex and CrossRef, along with a range of other validated data sources. The core bibliometric data used to establish the citation-based metrics integral to the ranking were meticulously collected on 2024-11-27. Institutional positions within the ranking result from the aggregated D-indexes (Discipline H-index) of all eligible scholars from each institution whose principal research contributions are in Engineering and Technology. The D-index is exclusively discipline-specific, taking into account only publications and citations within the field under examination.
Scope and Criteria of the Research
This year’s ranking undertook an extensive assessment, examining 279,971 scientist profiles drawn from a variety of bibliometric data sources. Specifically, 50,429 scholars with primary activity in Engineering and Technology were rigorously analyzed. In order to be considered, a scientist needed to have a minimum D-index of 30 within Engineering and Technology, and the majority of their leading publications had to reside in this discipline. In addition to bibliometric criteria, a scientist’s awards and field-specific achievements were also factored into the process.
The D-index qualifying threshold is determined dynamically, increasing by increments of 10 according to the overall number of researchers in the discipline, and is calibrated to ensure that the top 1% of global scholars are included in the ranking. To uphold disciplinary rigor, there must be no more than 30% difference between a scientist’s general H-index and their D-index for inclusion. As with the citation data, awards and achievements in their domain were important supplementary factors in profiling these top researchers.
Verification and Data Validation Practices
Cognizant of the limitations of raw bibliometric data for assessing scholarly contributions, the Research.com team committed to comprehensive manual verification of all scientist profiles. Each profile was cross-referenced against publications in an extensive array of reliable and respected sources within the academic literature. It is essential to note that while not a direct positional factor in the Research.com ranking, the volume of papers published in premier journals and conferences is recognized as a valuable secondary indicator of an individual’s influence within the discipline.
The final position in the ranking employs each scientist’s H-index, derived from the up-to-date and widely respected bibliometric databases, OpenAlex and CrossRef. The robustness and credence of these data sources guarantee a fair representation of scholarly impact within the field.
