Abstract:

Literature resources are fundamental to digital libraries, yet the challenge of insufficient ubiquitous service capability of these resources remains prominent. Taking academic papers as a representative type of literature resource, this study proposes a user ubiquitous annotation system. Firstly, a hierarchy model for user ubiquitous annotations was developed based on literature research and the Delphi method, followed by the design of a user ubiquitous annotation system to collect data on annotators, annotation behaviors and annotation content. Subsequent analysis, employing statistical analysis and time series, revealed key data characteristics. The study further examined the individual traits of the annotators, as well as the distribution and evolution of annotation content. Finally, through the combination of user experiments and questionnaires, a study was carried out to assess the effectiveness of the user ubiquitous annotation system in comparison to the traditional annotation method for reading academic papers. The findings revealed that the user ubiquitous annotation system can achieve higher user satisfaction by providing multidimensional view of the content and structure of academic papers. User ubiquitous annotation serves an important supplement to traditional classification topic annotation, offering an enhanced reading experience and improving the accessibility and usability of academic resources.
