| contents | Scopus is increasingly regarded as a high-quality and reliable data source for research and evaluation of scientific and scholarly activity. However, a puzzling phenomenon has been discovered occasionally: millions of records with author affiliation information collected in Scopus are oddly labeled as "country-undefined" by Scopus which is rarely to be detected in its counterpart Web of Science. This huge number of "homeless" records in Scopus is unacceptable for a widely used high-quality bibliographic database. By using data from the past 124 years, this brief communication tries to probe these affiliated but country-undefined records in Scopus. Our analysis identifies four primary causes for these "homeless" records: incomplete author affiliation addresses, Scopus' inability to recognize different variants of country/territory names, misspelled country/territory names in author affiliation addresses, and Scopus' insufficiency in correctly split and identify the clean affiliation addresses. To address this pressing issue, we put forward several recommendations to relevant stakeholders, with the aim of resettling millions of "homeless" records in Scopus and reducing its potential impact on Scopus-based literature retrieval, analysis, and evaluation. |
