Digital Diplomacy Glossary

A working reference of terms, concepts, and frameworks used across digital diplomacy, tech diplomacy, AI governance, narrative resilience, and institutional digital capability. The glossary grows alongside the knowledge areas.

About this glossary

Shared vocabulary for foreign affairs in digital environments.

Diplomats, policy teams, and institutional readers increasingly work across overlapping fields — digital diplomacy, cyber and tech diplomacy, AI governance, platform governance, narrative resilience, and digital sovereignty. Each carries its own language, history, and contested meanings.

This glossary offers a working reference for ministries of foreign affairs, embassies, international organizations, research institutions, and strategic partners who need a shared vocabulary across these domains. Each entry includes a short definition, why it matters for foreign affairs, where it appears in practice, and links to related terms and knowledge areas.

Entries are curated, not exhaustive. They are written from an institutional standpoint and refined as the knowledge base evolves.

Agentic AI: Agentic AI is the broader design paradigm in which AI systems pursue goals, use tools, coordinate actions, and operate with varying autonomy. It may be implemented through one AI agent or through multiple agents and services. Its autonomy is bounded by technical, organizational, legal, and policy constraints that institutions must deliberately define and govern.
Agrément: Agrément is the receiving state’s prior consent to the appointment of a proposed ambassador as head of mission.
AI Agents: AI agents are AI systems designed to pursue goals, complete tasks, interact with digital tools, make decisions within defined limits, and operate with varying degrees of autonomy. In foreign affairs, AI agents may assist with research, monitoring, workflow support, drafting, translation, triage, or internal coordination.
AI Assurance: AI assurance is the structured use of evidence, testing, evaluation, documentation, governance, and ongoing monitoring to determine whether an AI system satisfies defined requirements for performance, safety, security, legality, accountability, fairness, and institutional use. Assurance supports justified confidence; it is not a blanket guarantee that an AI system is safe or correct.
AI Diplomacy: The diplomatic, institutional, and strategic implications of artificial intelligence for foreign affairs — including how states negotiate AI governance, how ministries use AI internally, and how AI shapes information environments.
AI Governance: The rules, institutions, standards, safeguards, policies, and decision-making processes that shape how artificial intelligence is developed, deployed, used, and controlled — including both international negotiations about AI and the internal governance needed for ministries and diplomatic institutions to use AI responsibly.
AI Governance Diplomacy: Diplomatic engagement around how artificial intelligence is governed, developed, used, and coordinated across borders, with attention to safety, trust, accountability, sovereignty, and public interest.
AI Register: An AI register is a structured and maintained inventory of AI or algorithmic systems used, procured, developed, piloted, or authorized by an organization. It records information needed for governance, such as purpose, owner, provider, data, users, risk level, decision role, deployment status, safeguards, assurance evidence, review dates, and retirement or exit arrangements.
AI Response Cell: An AI response cell is a cross-functional team or working group responsible for helping an institution understand, govern, and respond to AI-related opportunities and risks. In a ministry of foreign affairs, it may bring together policy, digital, legal, cyber, communications, procurement, data, and regional expertise.
AI Sovereignty: AI sovereignty is the capacity of a state or institution to make meaningful, informed, and accountable choices about the models, data, compute, infrastructure, vendors, deployment arrangements, and exit options on which its use of AI depends. It does not require technological self-sufficiency. It requires enough capability, leverage, and control to choose, govern, verify, change, or leave those arrangements while protecting strategic choice and public authority.
AI-Augmented Diplomacy: AI-augmented diplomacy refers to the use of artificial intelligence to support, accelerate, or improve diplomatic work while keeping human judgment and responsibility at the center. It may assist with analysis, translation, drafting, monitoring, scenario planning, knowledge management, and operational coordination.
Aide-mémoire: An aide-mémoire is a written summary of a diplomatic conversation or representation, provided to preserve the main points for subsequent reference.
Algorithmic Influence: The way digital platforms, recommendation systems, search engines, feeds, and automated ranking mechanisms shape what people see, notice, believe, and discuss online.
Algorithmic Public Diplomacy: The practice of understanding how platform algorithms shape visibility, audience segmentation, narrative spread, and public engagement in diplomatic communication.
Algorithmic Transparency: Algorithmic transparency is the practice of making accessible and intelligible information available about where, why, and how algorithmic or AI systems are used, what role they play in decisions, which data and safeguards are involved, who is accountable, and what limitations or routes for review exist. It does not always require public disclosure of source code.
Ambassador: An ambassador is a state's highest-ranking diplomatic representative accredited to another state or, in a different institutional form, to an international organization. An ambassador normally leads an embassy or permanent mission, represents the sending state's positions, and acts under the authority and instructions of the sending government.
Arms-Control Diplomacy: International negotiations aimed at limiting, regulating, monitoring or verifying weapons and military capabilities.
Arria-formula Meeting: An Arria-formula meeting is an informal gathering organized by one or more UN Security Council members to hear views and exchange information outside the Council’s formal meeting formats.
Arts Diplomacy: Cross-border engagement through artistic creation, exhibitions, performances and institutional exchange to support relationships or mutual understanding.
Auditability: Auditability is the degree to which a system, process, or decision can be independently examined and reconstructed using reliable records of inputs, outputs, actions, changes, identities, approvals, rules, and relevant context. Auditability enables accountability and learning, but it requires records that are complete, protected, interpretable, and accessible to authorized reviewers.
Automation Bias: Automation bias is the tendency to give excessive weight to outputs or recommendations from automated systems, leading people to overlook contradictory evidence, fail to notice system errors, or accept a machine-supported conclusion without sufficient independent judgment. It can occur even when a human formally remains responsible for the decision.
