Thesis Abstract

This study addresses the fragmentation of user access and disparate usage patterns in institutional digital repositories, which impede efficient discovery, reuse, and scholarship. It advances a hybrid framework that integrates access motif detection with repository analytics to predict and enhance user engagement across heterogeneous collections. The aim is to develop a theory-driven model that unifies access pathways, usage motifs, and content semantics to inform repository design and curation. Specific objectives are (1) to identify recurring access motifs through sequence mining of user interactions; (2) to model the relationship between metadata quality, repository features, and motif prevalence; (3) to evaluate the predictive power of the framework for user satisfaction and repository reuse; (4) to propose design interventions and governance policies to optimize access and usage; and (5) to validate the framework across diverse disciplinary repositories. Methodologically, the study adopts a mixed-methods design anchored in activity theory and information foraging theory to capture both quantitative usage signals and qualitative user experiences. The population comprises four institutional repositories within a European university consortium, hosting approximately 2.1 million items collectively. A stratified random sample of 800,000 access events over a 24-month period will be drawn, including user sessions, item-level interactions, search queries, and retrieval actions. Data collection instruments include server log extracts, metadata records (including Dublin Core and METS where available), and a structured user survey administered to 380 active researchers across disciplines. Complementary semi-structured interviews with 25 repository managers and senior librarians will elucidate governance practices affecting access. Data analysis will employ (i) sequence mining (PrefixSpan) to extract access motifs; (ii) hierarchical clustering to categorize motif families; (iii) regression analysis and structural equation modeling (AMOS) to test the relationships among metadata quality, feature set, motif prevalence, and outcomes (satisfaction, reuse); (iv) time-series analysis to explore temporal dynamics of motifs; (v) thematic analysis of interview transcripts to triangulate quantitative findings with stakeholder perspectives. Model specification will articulate a hybrid framework consisting of three layers the Access Motif Layer (motif types and transition probabilities), the Metadata-Feature Layer (quality, completeness, and repository affordances), and the Outcome Layer (satisfaction, reuse intention, and scholarly impact). Expected findings include (a) a taxonomy of primary access motifs such as direct item retrieval, topical browsing, author-based exploration, and citation-driven navigation, with transition probabilities revealing navigation flows; (b) a positive association between metadata completeness, faceted search capabilities, and motif complexity, which in turn predicts higher satisfaction and reuse rates; (c) evidence that certain motifs correlate with higher scholarly impact indicators, such as downstream downloads and citation reach; (d) identification of governance practices that enable or constrain motif diversity, including curation cycles and user analytics transparency. The study anticipates that the hybrid framework will achieve robust predictive validity (R2 > .40) for user satisfaction and reuse across repositories, with stable motif classifications over time. Contributions to knowledge include (i) a novel integrative model linking access motifs, repository features, and user outcomes within a unified theoretical lens combining activity theory and information foraging concepts; (ii) an empirical mapping of motif-based user journeys that informs repository design, metadata practices, and analytics-driven governance; (iii) methodological advances in applying sequence mining and SEM to large-scale repository analytics; and (iv) practical guidelines for enhancing discoverability, accessibility, and reuse without compromising privacy or data security. The study concludes that a strategically engineered hybrid framework can harmonize user behavior patterns with repository capabilities, enabling proactive curation and feature optimization. Recommendations focus on enhancing metadata quality standards, expanding adaptive search interfaces guided by motif analytics, implementing ongoing motif-based monitoring dashboards for repository managers, and aligning access policies with stakeholder-driven governance to sustain meaningful engagement and scholarly impact.

Thesis Overview

The research explores how digital repositories can be accessed more effectively and how users reveal patterns of interaction that lead to better discovery and reuse of stored materials. It addresses the gap that existing frameworks often treat access and usage motifs separately or rely on narrow metrics, missing the dynamic interplay between user behavior, repository design, and content organization. Why it matters: Digital repositories are central to scholarly communication, yet many fail to optimize user pathways or to align access controls, metadata, and search tools with real user needs. A hybrid framework that unifies access mechanisms with usage motifs can improve findability, increase reuse, and inform design decisions for repositories in universities and research institutions. Problem or knowledge gap: There is limited theory that integrates access features (search, browse, authentication, metadata richness) with observed usage motifs (patterns like exploratory browsing, targeted retrieval, repeated reuse). The study proposes a model that connects technical access components with behavioral patterns to explain how users interact with repositories and where friction or drop-off occurs. What the researcher will do (step by step): - Conduct a literature review to identify existing access models and usage motifs and extract key variables. - Design a mixed-methods study combining quantitative log analysis with qualitative interviews. - Data collection: - Collect repository access logs from three university repositories over 12 months (approximately 1.2 million events; anonymized). - Interview 40-50 active users (students, faculty, and external researchers) to capture motivations and pain points. - Data analysis: - Use sequence analysis and clustering on log data to identify distinct usage motifs (e.g., targeted retrieval, exploratory discovery, iterative refinement). - Apply regression analysis to examine relationships between access features (search quality, metadata richness, interface customization) and motif prevalence. - Conduct thematic analysis of interview transcripts to contextualize motifs and uncover design implications. - Integrate findings into a conceptual hybrid framework that links access characteristics with usage motifs. - Validate the framework through expert review with repository designers and iterative refinements. Contribution and expected outcome: - A unified theoretical framework that explains how access mechanisms influence user usage motifs in digital repositories. - Practical guidelines for repository design, metadata practices, and user interface features to improve discoverability and reuse. Potential limitations and future work: - Results may be context-specific to participating repositories; future work could test the framework in diverse institutional settings.
