PRIMA Search – Mission archives

Ministry of Defence

Being able to search mission archives quickly, efficiently and thoroughly is important for the Ministry of Defence. To make the mission archives more searchable, the Ministry of Defence is using various AI models. AI supports the smart and targeted search for information in the mission archives. For example, when searching for specific words (keywords) or when asking questions with a specific context.

Goal and impact

The aim of the algorithm is to facilitate the answering of specialist search queries regarding historical information on parliamentary missions, Woo requests and parliamentary questions.

Considerations

The volume of data and the nature of mission information make it practically impossible to answer specialist search queries or to meet the statutory deadlines for a Woo request. The use of AI to search through this information is therefore essential.

Human intervention

There is no automated decision-making involved. A human assesses the search results for relevance.

Risk management

Risk management forms part of the development process. Performance is monitored to ensure technical accuracy. The internal DPIA contains a comprehensive overview of the privacy risks.

Legal basis

The legal basis for the processing is Article 6(1)(e) of the GDPR: the processing is necessary for the performance of a task carried out in the public interest entrusted to the controller. This relates to the legal obligation set out in Articles 2.4 and 4.4 of the Woo and Article 3 of the Archives Act 1995.

Data

All information created during a mission and transferred to the Semi-static Information Management (SIB) archive.

Technical design

The applications in which the Ministry of Defence uses algorithms may be operationally sensitive or classified. The Ministry of Defence therefore provides only general information about the technical functioning of its algorithms. The Ministry of Defence uses a language model (LLM) that supports the searching of mission archives. An LLM utilises semantic information (the meaning and context of words and sentences) to process language not merely as a sequence of characters, but as meaningful concepts. This enables the model to understand relationships, interpret context and make connections that go beyond mere keywords.
