We are pleased to announce the Call for Papers for the ALTARS Workshop (Advanced Legal and Terminology-Aware Retrieval Systems), which will be held as part of The Web Conference 2026.

https://altars2026.dei.unipd.it/

ALTARS explores new methodologies that bridge high-recall retrieval, Web intelligence, and responsible AI, with a special emphasis on Technology-Assisted Review (TAR) at Web scale. The workshop aims to gather researchers and practitioners focused on foundational and applied advances in transparent, reliable, and domain-aware retrieval and review systems.
Topics of Interest

We invite contributions on, but not limited to, the following themes:
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
