About ALTARS

ALTARS 2026 – Augmented Intelligence in Technology-Assisted Review Systems explores advanced methods for high-recall retrieval and adaptive review workflows across large-scale, heterogeneous, and dynamic Web environments. Technology-Assisted Review (TAR) systems, once used primarily in legal discovery and systematic literature reviews, are increasingly essential for navigating today’s Web, where information volume, diversity, and uncertainty continue to accelerate.

As AI-generated and user-generated content reshape the Web’s information landscape, TAR methods offer structured and transparent approaches for identifying, ranking, and validating relevant content. ALTARS 2026 brings together researchers and practitioners in information retrieval, Web science, artificial intelligence, legal informatics, biomedical information management, and digital governance to discuss how TAR methodologies can support trustworthy, explainable, and scalable Web-based information access.

The workshop provides a forum for interdisciplinary dialogue, presentations of cutting-edge research, and collaborative exploration of open challenges in building transparent and responsible review systems for the Web.

Call for Papers

ALTARS 2026 invites contributions on innovative methods, practical applications, and theoretical foundations of Technology-Assisted Review (TAR) systems in Web-scale environments. We welcome research papers, position papers, negative results, system demonstrations, and application-driven case studies.

Accepted papers will be presented during the workshop and included in the publicly accessible workshop proceedings. We encourage participation from academia, industry, government, and nonprofit sectors, and we particularly welcome submissions from early-career researchers.

Submissions may cover novel algorithms, evaluation protocols, user-in-the-loop workflows, Web-scale applications, and ethical or governance-related perspectives. Papers should provide clear methodological contributions or conceptual insights, supported by empirical evidence, prototypes, or reflective analysis.

Topics of Interest

We invite contributions on, but not limited to, the following themes, which bridge high-recall retrieval, Web intelligence, and responsible AI:

1. Web-Scale Applications of Technology-Assisted Review

Research on applying Technology-Assisted Review (TAR) methodologies to large and dynamic Web environments, including:

• Scientific knowledge curation and evidence synthesis
• Open data discovery and enrichment
• Legal, biomedical, environmental or governmental Web content review
• Misinformation detection and content integrity
• Multilingual and cross-domain review pipelines

2. Intelligent and Hybrid Retrieval on the Web

Studies that combine TAR principles with Web-scale search and representation frameworks, such as:

• LLM-based retrieval-augmented generation (RAG)
• Semantic search and entity-centric retrieval
• Integration of knowledge graphs and structured Web data
• Adaptive or high-recall ranking strategies
• Retrieval workflows for heterogeneous information sources

3. Interactive, Explainable, and Human-in-the-Loop TAR

Research focusing on transparent, interpretable, and user-centered TAR systems, including:

• User-in-the-loop review and collaborative curation systems
• Explainable AI methods for document triage and prioritization
• Uncertainty and confidence estimation for AI-assisted decisions
• Evaluation of interaction models and review interfaces

4. Responsible and Fair Web Review Systems

Investigations into fairness, accountability, and ethical design of Web-scale review workflows, such as:

• Bias detection and mitigation in large-scale content filtering
• Responsible and trustworthy AI in regulatory, journalistic, or civic contexts
• Auditability and transparency of TAR workflows
• Human oversight and governance for automated review systems

Submissions

Research papers, describing original ideas on the listed topics and on other fundamental aspects of Technology-Assisted Reviews methodologies and technologies, are solicited. Moreover, short papers on early research results, new results on previously published works, and extended abstract on previously published works are also welcome.

Submission Format

• Research papers presenting original works up to 4 pages
• Posters ongoing works, tool presentations, research demos and position papers up to 2 pages

For all submission types, references are counted in the page limit.

Publication

Accepted papers can be included in the Companion Proceedings of the Web Conference 2026, subject to meeting the official camera-ready timeline.
