A Legal Framework for Natural Language Processing Model Training in Portugal
Recent advances in deep learning, particularly LLMs like ChatGPT, have revolutionized NLP but also raised significant copyright and data privacy concerns. This paper addresses these legal challenges within the Portuguese context, bridging the gap between legal experts and computer scientists to promote compliant NLP research. It highlights everyday NLP use cases and relevant Portuguese and EU legislation, focusing on mid-resourced languages like Portuguese and the impact of Brazilian Portuguese resources.

Portuguese & European AI Law
The legal landscape for AI and NLP in Portugal is shaped by both national laws and overarching EU regulations. Understanding these layers is crucial for compliant development.
- Portuguese Legal System: Distinguishes between civil and penal codes, with many NLP-relevant issues falling under civil law. Mass adoption of CS has brought penal considerations for copyright and privacy.
- Sensitive Data Protection: Article 35 of the Portuguese Constitution strictly prohibits digital processing of sensitive ethnic, political, sexual, or religious data without explicit consent. NLP researchers are advised to avoid such data.
- Right to Expression: Article 79 of the Portuguese civil code protects free expression, with exceptions for scientific research, allowing for data sources like tweets (if anonymized and non-sensitive).
- GDPR (Regulation EU 2016/679): Enacted in 2016, this EU regulation sets foundational standards for data protection. It mandates transparency, explicit consent for data collection/usage, and minimization of private data. Fully integrated into Portuguese law in 2021.
- Copyright in Digital Single Market (Directive EU 2019/790): Introduced a 'right to text mine,' permitting scientists to use copyrighted data for NLP model training if not for profit. Transposed into Portuguese law in 2023.
- Database Sui Generis Protection (Directive 96/9/EC): Grants 15 years of copyright protection for independent database compilations, with scientific exceptions.
- AI Act (Regulation COM 2021/206): The EU's comprehensive AI legal framework. Most NLP research is categorized as 'minimal-risk,' exempting from additional considerations. Expected to be fully implemented in ~2 years.
Scientific Exceptions: Portuguese law and EU directives define scientific work (e.g., conducted by universities, research institutes, not-for-profit) which often permits certain uses of data that would otherwise be restricted, provided profit is not the primary goal and ethical standards are met.
The State of Portuguese NLP
Portuguese, spoken by 260 million people, is a mid-resourced language in NLP terms, yet development often relies heavily on resources from Brazil.
- Mid-Resourced Language: Characterized by large amounts of unlabeled data but fewer labeled resources, posing challenges for NLP development.
- Brazilian Portuguese Dominance: The vast majority of existing Portuguese NLP resources and models (e.g., BERTimbau) originate from Brazil.
- Emerging European Portuguese LLMs: Recent years have seen the development of models like Albertina PT, Sabiá, Gervásio, and GlórIA specifically for European Portuguese.
- Leveraging Brazilian Resources: Prompt engineering and fine-tuning of Brazilian LLMs are crucial for European Portuguese researchers to achieve state-of-the-art results due to the historical resource gap.
NLP Licensing and Data Compliance
Proper licensing and compliance are paramount for the legal and ethical development of NLP models, especially with diverse data sources.
- Common LLM Licenses: Many prominent Large Language Models (LLMs) adopt permissive licenses like Apache 2.0 or MIT, facilitating broader use.
- Dataset Licensing: NLP datasets frequently utilize Common Crawl licenses. For instance, the Portuguese LLM GlórIA adopted the ClueWeb22 license due to its training data.
- Geographical Origin vs. Compliance: The geographical origin of a dataset (e.g., Brazilian Portuguese) does not impact its overall legal assessment for NLP applications developed under EU law. Compliance is determined by the data's characteristics and the intended use within the EU legal framework.
- Impact of Copyrighted Data: An LLM trained on copyrighted data may inherit similar licensing implications if it can reproduce copyrighted material. There's a need for clarity on how much copyrighted data triggers this "derivation" status.

Data Sensitivity & Political Profiling: Lessons from Cambridge Analytica
The Facebook-Cambridge Analytica scandal serves as a stark reminder of the legal and ethical pitfalls associated with processing sensitive personal data for political profiling using NLP. This use case highlights the critical need for explicit consent, strict anonymization, and adherence to regulations like GDPR when dealing with data that can reveal political opinions or other sensitive attributes.
Key Findings for Enterprise AI:
- Processing sensitive data (e.g., political opinions) is strictly prohibited without explicit consent by Article 35 of the Portuguese Constitution and GDPR.
- Data anonymization and minimization are essential to mitigate risks, even with consent.
- Scientific research can have exceptions, but these are narrow and require careful consideration.
- Automated processing of sensitive data, especially for profiling, carries high legal and ethical risks.
