A key metric for determining a scientist’s position in the ranking is the D-index (Discipline H-index). Unlike a general H-index, the D-index focuses exclusively on papers and citations within the examined discipline, providing a more precise evaluation of a researcher's influence and contributions in Computer Science.
Scope of Research and Qualification Criteria
The ranking was compiled following an exhaustive examination of 279,971 scientist profiles identified from an extensive range of bibliometric sources covering all scientific disciplines. Among these, 49 scientists specializing in Computer Science within Norway were closely evaluated.
To qualify for inclusion in the ranking, a researcher’s D-index must be at least 30, and a significant majority of their tier publications must have been produced within the field of Computer Science. Additionally, awards and achievements specifically related to Computer Science were taken into consideration, further substantiating a researcher’s standing.
The D-index threshold for recognizing top researchers is dynamically set in increments of 10 based on the estimated total number of scholars in each discipline. This approach guarantees that the top 1% of leading experts are represented in the list. Furthermore, the methodology ensures that there is a proximity of no more than 30% between a scientist’s general H-index and their D-index, thereby maintaining focus on discipline-specific contributions.
Verification and Validation Procedures
At Research.com, we acknowledge that raw bibliometric data should not be treated as an absolute tool for evaluating scholars’ outputs. In recognition of this, all scientist profiles featured in the ranking underwent meticulous manual verification. This process included cross-correlating publication data across numerous trustworthy sources to validate the accuracy and relevance of the information.
While not directly influencing a researcher's ranking position, the volume of papers published in prominent journals and conference proceedings serves as a valuable secondary signal reflecting a scientist’s contribution to their field. The core ranking metric—the D-index—is computed using data exclusively from OpenAlex and CrossRef, the two most prominent and widely recognized bibliometric databases available to the research community.
