## metaScreener: A Human-AI Collaborative Desktop Tool for Systematic Literature Screening (Introduction)

In fields such as academic research and pharmacovigilance, Systematic Literature Review (SLR) is a core method for obtaining high-quality evidence. However, manual screening has issues like being time-consuming, labor-intensive, and subject to subjective differences. metaScreener is an open-source desktop application developed by the Laval University team. By combining deterministic heuristic rules with large language model reasoning, it builds an auditable pipeline to achieve human-AI collaborative literature deduplication and relevance assessment, aiming to address the efficiency and accuracy challenges in SLR screening.

## Project Background and Core Positioning

Systematic literature reviews require reviewing each article according to inclusion/exclusion criteria, divided into initial screening of titles and abstracts and full-text detailed screening. Large-scale projects may handle tens of thousands of articles in the initial screening phase, resulting in extremely high labor costs. metaScreener is positioned as a human-AI collaborative workbench; it does not pursue full automation but instead amplifies researchers' decision-making capabilities through technology while retaining the final adjudication right of human experts.

## Plug-in Pipeline Architecture: Balancing Efficiency and Accuracy

metaScreener adopts a plug-in architecture, with its core screening logic being a pipeline composed of configurable processing nodes. Node types include:
- **Deterministic Filter**: Quickly eliminate obviously irrelevant literature based on rules (keywords, publication year, literature type, etc.);
- **LLM Reasoning Node**: Call large language models to handle complex judgments (e.g., whether the research design meets requirements).
The hybrid architecture balances efficiency (fast filtering via rules) and accuracy (semantic understanding via LLM).

## Academic Norm Assurance: Auditable and Reproducible Design

metaScreener values academic transparency and reproducibility:
- **Decision Log**: Records the processing trajectory of each article (filter pass/exclusion status, LLM judgment reasons);
- **SHA-256 Verification**: Ensures the integrity of the software version to avoid result deviations;
- **Configuration Export**: Screening strategies can be exported as configuration files for easy collaboration and reproducibility.

## Human-AI Collaborative Workflow

Typical usage workflow of metaScreener:
1. **Import Literature**: Import literature to be screened from EndNote, Zotero, or database search results;
2. **Configure Pipeline**: Set up screening nodes according to inclusion/exclusion criteria (e.g., keyword filtering first, then LLM semantic judgment);
3. **Automatic Initial Screening**: The system categorizes literature into three types: definitely included, definitely excluded, and needing manual review;
4. **Manual Adjudication**: Researchers handle literature needing review; the interface displays metadata, abstracts, and LLM reasons to assist decision-making;
5. **Export Results**: Export the included list and decision logs for writing the review methodology.

## Open-Source Ecosystem and Applicable Scenarios

metaScreener is open-source under the MIT license and supports cross-platform use on Windows, macOS, and Linux. Its plug-in architecture facilitates community contributions (e.g., discipline-specific filters, LLM integration plug-ins). Applicable groups include:
- Systematic review researchers (evidence-based fields such as medicine and psychology);
- Pharmacovigilance teams (monitoring drug safety signals);
- Policy analysts (grasping the current state of thematic research);
- Bibliometric scholars (large-scale literature preprocessing).

## Conclusion: The Future of Human-AI Collaborative Academic Tools

metaScreener embodies a pragmatic AI application concept: it does not replace humans but enhances human capabilities. In fields like literature screening that require large-scale data processing and complex judgments, human-AI collaborative solutions are more reliable and practical. As LLM capabilities improve, such tools will play an increasingly important role in academic research.
