From Tabs to Structures: Understanding and Supporting Web Page Management

Publication Info

• Topic area: Web page management and user interface design for knowledge workers.
• Keywords: web page management, tab overload, knowledge workers, information structuring, multi-tasking, deferred classification, user interface design, activity-based computing, technology probe, browser usage.

Background and Problem

• Problem / challenge: Knowledge workers face challenges managing browser tabs and web pages due to uncertain relevance, leading to cluttered workspaces, tab overload, and difficulty re-finding information. Existing solutions like bookmarks and reading lists are either too rigid or become unmanageable over time.
• Significance: Effective web page management is critical for productivity and reducing mental load, especially in environments characterized by multi-tasking and information overload.
• Motivation and related work: Prior research has explored bookmarking systems, tab management, and activity-based computing, but these approaches often impose rigid structures or fail to address the dynamic and evolving nature of web page relevance. This paper builds on these insights to propose a more flexible and integrated solution.

Solution

• Proposed approach: Gstell, a technology probe that integrates short-term (Shelf) and long-term (History) storage to accommodate evolving relevance and emerging structures of web pages.
• Novelty:
  1. Explicit support for uncertain and evolving relevance of web pages.
  2. Integration of short-term and long-term storage to enable deferred structuring.
  3. Lightweight grouping and labeling for dynamic and activity-based organization.
  4. Recency-based ranking and activity multiplexing to support task switching and re-finding.
• Procedure and key techniques:
  • Gstell provides a Shelf for temporary storage and a History for longer-term organization.
  • Users can save web pages without immediate classification and later transition them into labeled groups.
  • Groups are dynamically ranked by recency, and users can open/close entire groups for task switching.
  • A browser extension tracks tab usage and integrates with the standalone Gstell application.

Results

• Concrete findings:
  • Participants saved an average of 28.93 web pages during the intervention, with 88.43% of these pages closed within minutes of saving.
  • Participants spent an average of 5.96 hours per workday in the browser, switching tabs 63.66 times per hour.
  • The average number of open tabs decreased by 58.59% during the intervention phase, though this was not statistically significant across all participants.
  • Gstell achieved a System Usability Scale (SUS) score of 88.45, indicating high usability.
• Advantage over baselines:
  • Gstell reduced perceived tab overload and increased focus for participants.
  • It enabled more proactive tab closure and facilitated the emergence of meaningful task- and topic-based structures.
• Experiments / evaluation:
  • A multi-week field study with 29 participants (primarily IT professionals and students) was conducted.
  • Data collection included browser monitoring, experience sampling, pre- and post-study questionnaires, and semi-structured interviews.
  • Metrics included tab counts, recurrence rates, vocabulary size, and qualitative feedback.
• Limitations and future work:
  • Limited generalizability due to the specific demographic (predominantly IT professionals and students).
  • Short study duration may not capture long-term adoption patterns.
  • Future work should explore diverse user groups, longer-term deployments, and additional features like automated grouping suggestions.

Summary

This study introduces Gstell, a tool designed to address tab overload and support dynamic web page management for knowledge workers. By integrating short-term and long-term storage, Gstell allows users to save web pages without immediate classification, enabling the emergence of task- and topic-based structures over time. A multi-week field study with 29 participants demonstrated that Gstell reduced tab overload, increased focus, and encouraged proactive tab management. While the study highlights the potential of Gstell to improve web page management, future work is needed to assess its long-term effectiveness and applicability across diverse user groups.
