A Review and Perspective of Questioned Document Examination Research – Bibliometric Analysis Based on Visual Knowledge Mapping

Resumen

Background: Questioned document examination (QDE) is a crucial sub-discipline of forensic science, and over the years, this discipline has developed a vast amount of research results and literature. However, the current studies have only reviewed the development of QDE for a period of time or a particular research direction, lacking a comprehensive review of this discipline since its origins. Aim: The aim of this study is to utilize bibliometric methods to review the history and development of QDE since 1934 and also to predict its future research trends. Materials: This study collects the literature of questioned document examination (QDE) from the Web of Science Core Collection database and uses four bibliometric analysis tools: CiteSpace, VOSviewer, SciMAT, and Bibliometric, to process relevant literature data. Methods: Through the analysis methods of journal co-citation analysis, keyword co-occurrence network analysis, literature cocitation analysis, and theme evolutionary analysis, the bibliometric data information in the QDE field is obtained, and a visualized knowledge mapping is constructed. Results: The results show that four research directions have been formed, basically. As far as the development trend of QDE research is concerned, the research field shows the change in content from cursory to detailed and in analysis from qualitative to quantitative, while the research field maintains a close relationship with chemical technology and computer science. Conclusions: The changes in QDE can be attributed to advancements in science and technology, which have influenced research methods. QDE also has a legal aspect, with a focus on enhancing scientific accuracy and evidentiary value. These developments aim to strengthen QDE’s identification power and promote its scientific and standardized growth. This will gradually enhance the reliability and strength of QDE evidence, making it more valuable in judicial practice.
