Enhancing User Search Experience in Digital Libraries with Rotated Latent Semantic Indexing

This study investigates a semi-automatic method for creation of topical labels representing the topical concepts in information objects. The method is called rotated latent semantic indexing (rLSI). rLSI has found application in text mining but has not been used for topical labels generation in digital libraries (DLs). The present study proposes a theoretical model and an evaluation framework which are based on the LSA theory of meaning and investigates rLSI in a DL environment. The proposed evaluation framework for rLSI topical labels is focused on human-information search behavior and satisfaction measures. The experimental systems that utilize those topical labels were built for the purposes of evaluating user satisfaction with the search process. A new instrument was developed for this study and the experiment showed high reliability of the measurement scales and confirmed the construct validity. Data was collected through the information search tasks performed by 122 participants using two experimental systems. A quantitative method of analysis, partial least squares structural equation modeling (PLS-SEM), was used to test a set of research hypotheses and to answer research questions. The results showed a not significant, indirect effect of topical label type on both guidance and satisfaction. The conclusion of the study is …

Readiness of Indonesian Academic Libraries for Open Access and Open Access Repositories Implementation: a Study on Indonesian Open Access Repositories Registered in OpenDOAR

Scholarly and scientific communication has a long history, while the Open Access (OA) movement began to take part in this communication with the emergence of Internet in the late 1960s and the web that emerged in mid-1990s. OA is beneficial for sharing knowledge because the OA movement demands scholarly literature freely available on the internet and it is free of most licensing restriction copyright. OA will close the barrier of access to knowledge. The OA movement in Indonesia may be considered slow. So far, only 33 academic libraries have registered their repositories with OpenDOAR, which is still small compared to the total number of HE institutions in Indonesia. Those 33 OARs vary in the stages of development. Some have already had large size of contents, while others are still developing. Using Weiner’s theory of organizational readiness for change, this mixed method investigates the readiness of academic librarians for Open Access Repository implementation. The results show that academic librarians in Indonesia are somewhat familiar with OA and OAR. However, their understanding of OA is still limited to the technical nature of it. They also know the benefits of OA in relation to scholarly communication and are ready to implement OAR, but …
