Summary
Dimensions database offers greater coverage than Scopus but lacks crucial affiliation data for nearly half its documents. This impacts bibliometric analysis at country and institutional levels.
Area of Science:
- Bibliometrics
- Information Science
- Scientific Databases
Background:
- Bibliographic databases are essential for research evaluation.
- Scopus and Dimensions are major sources for bibliometric analysis.
- Understanding data coverage differences is crucial for accurate research assessment.
Purpose of the Study:
- To compare document coverage between Scopus and Dimensions at country and institutional levels.
- To assess Dimensions' suitability for bibliometric analysis beyond global metrics.
- To investigate citation link accuracy and completeness in both databases.
Main Methods:
- Large-scale document-level comparison of Scopus and Dimensions.
- Analysis of document aggregation by country and institution.
- Evaluation of affiliation data completeness and citation link accuracy.
Main Results:
- Dimensions exhibits over 25% greater document coverage than Scopus.
- A significant finding is the lack of country affiliation data for approximately 50% of Dimensions documents.
- Scopus demonstrates a lower proportion of documents missing affiliation data.
Conclusions:
- Dimensions' extensive coverage is advantageous but hampered by missing affiliation data for country/institutional bibliometrics.
- The data gap in Dimensions limits its utility for detailed research evaluation at sub-global levels.
- Careful consideration of data completeness is vital when selecting scientific databases for research policy and information retrieval.

01:11Statistical Analysis: Overview
11.3K
When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
One of the most commonly used statistical quantifiers is the mean, which is the ratio between the sum of the numerical values of all results and the...

01:40Archival Research
16.7K
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

01:11Observational Studies
10.3K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

01:12Analysis of Population Pharmacokinetic Data
522
Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...

02:46Chi-square Analysis
41.3K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

01:23Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
223
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...
