Greece AI Hub

Artificial Intelligence Hub Efficient and Responsible AI

Empowering organizations with innovative AI solutions that drive efficiency, transparency and trust.

What We Do

Systems we design, build
and stand behind

Every capability below is drawn from work the Hub has delivered, prototyped or architected, not from a catalogue. The common thread is deterministic-first design: the decision path stays auditable, and generative components are used where they add value rather than where they are easiest to insert.

13Capability families
48Documented capabilities
60+Technologies in use
7Delivery domains
01

Document intelligence and information extraction

Pipelines that turn unstructured PDFs into structured records through parsing, OCR and layout analysis, loaded into relational stores. Rule-based extraction is preferred wherever it will hold, so results remain explainable and reproducible.

02

Entity resolution and record linkage

Deduplication and canonicalisation of people, organisations and departments across large inconsistent datasets, combining string similarity, phonetic matching and normalised reference data.

03

Semantic search and intent classification

Embedding-based routing of free-text queries against defined intents, with similarity scoring, entity-aware filtering, calibrated confidence thresholds and the ability to abstain rather than guess.

04

Evidence-grounded knowledge systems

Retrieval architectures connecting scientific, policy and organisational corpora to language models, designed around source grounding, provenance and traceability rather than fluency alone.

05

Agentic workflows

Orchestrated multi-agent flows with defined roles, graph-backed retrieval and streaming interfaces, benchmarked against single-agent baselines before they are trusted with a task.

06

Cybersecurity AI advisory

Security posture and vulnerability reporting in which intent resolution, query planning and evidence assembly are fully deterministic, and the language model is confined to wording an already-assembled result.

07

Graph and relational data architecture

Cloud and local data estates across relational and graph stores, including migrations, validation queries, access control and self-healing retrieval workflows.

08

Cross-border and enterprise architecture

Secure message exchange, data validation and connector coordination across national administrations, delivered against specifications, quality assurance and service-level commitments.

09

Responsible AI assurance

Bias auditing, explainability evidence and trustworthiness assessment aligned to ISO/IEC 42001, the EU AI Act and GDPR, produced as artefacts a reviewer or auditor can act on.

10

AI technology assessment and strategy

Independent assessment of proposed solutions for methodological validity, technical feasibility, data dependencies, interoperability and organisational fit, ahead of commitment.

11

Containerised delivery and integration

Reproducible deployment of AI and security services, event-driven integration patterns and continuous integration workflows with automated regression protection.

12

Research and quantitative data analytics

Analytical workflows over science, technology and innovation data, from operationalisation and preparation through analysis, validation and interpretation.

What We Train

Models, and the people
who will run them

Training is treated as two obligations. The first is to the model: trained on data we can account for, evaluated against the failure that actually matters, and released with its limitations written down. The second is to the organisation receiving it, which has to operate the result long after we have gone.

Models we train and fine-tune
  • Domain-specific named entity recognitionTransformer-backed NER fine-tuned on GPU for specialist vocabularies, with annotation and dataset review managed through a controlled labelling workflow.
  • Transformer fine-tuning for semantic similarityEncoder models adapted to regression on textual similarity, evaluated on rank correlation rather than accuracy alone.
  • Sequence models for text classificationRecurrent architectures for toxicity and content classification, comparing task-learned embeddings against pretrained vectors.
  • Calibrated classifiers for auditable routingSparse linear models with probability calibration and out-of-scope rejection, chosen where a decision must be inspectable and defensible rather than merely accurate.
  • Image classification and visual pipelinesConvolutional and transformer vision architectures alongside classical feature pipelines using colour statistics, entropy and local binary patterns.
  • Deep reinforcement learning agentsValue-based agents and their variants, with replay buffers, target networks and systematic comparison across configurations.
  • Biosignal early-warning modelsPhysiological time-series classifiers evaluated on lead time and false-alarm burden, because sensitivity and specificity alone do not describe a continuous monitoring system.
  • Embedding-based semantic routersRetrieval and routing models with calibrated thresholds and an explicit evaluation methodology built alongside the classifier.
How we train
  • Deterministic firstIf a rule, a lookup or a linear model will do the job reliably, it does the job. Learned components are introduced where they earn their place, not by default.
  • Evaluation designed before deploymentThreshold calibration, abstention behaviour and out-of-scope handling are specified as part of the model, not discovered afterwards.
  • Synthetic data where reality is scarcePhysiologically grounded synthetic corpora generated under declared assumptions, with a defined release pathway and research-ethics review before distribution.
  • Regression protectionAutomated test suites over pipeline behaviour, including masking, filtering and safety-check logic, so a change cannot quietly degrade a released model.
  • Documented limitationsEvery release travels with an evaluation record and a statement of what it cannot be relied upon to do.
Capability we transfer
  • AI in cybersecurity instructionDelivered within a NATO maritime interdiction training programme.
  • Responsible AI and governance workshopsFor public-sector bodies adopting AI under regulatory obligation.
  • Digital learning platformsAdaptive e-learning, standards-based curricula and offline-capable training applications.
  • Multi-administration coordinationSpecification workshops, guidance authorship and structured knowledge transfer across national delegations.
We Like Research

Open questions we work on,
not just problems we bill for

A working research programme runs alongside delivery. Some of it is peer-reviewed and externally funded, some is early and openly incomplete. Both are listed here, because a research claim that hides its unfinished parts is not worth reading.

AI metrics and indicator design

Indicators for measuring AI capability, adoption and impact, with emphasis on validity and interpretability in science, technology and innovation systems.

Scientometrics and research evaluation

Quantitative analysis of scientific activity, collaboration and emerging technologies, including methodological assessment of indicator validity and responsible evaluation practice.

Metascience and AI-mediated inquiry

How AI changes scientific knowledge production, evidence generation and scholarly communication, examined through validity, reliability, transparency and reproducibility.

Generative AI in scientific knowledge work

The consequences of generative systems for evidence production, research quality and the evaluation of research itself.

Explainability as a primary output

A framework treating explanation as an artefact produced during inference rather than a visualisation reconstructed afterwards, built on epistemic subspaces covering semantic validity, temporal volatility, interaction continuity and coherence, with declared instantiations across cyber, legal and medical domains.

Agentic workflows for evidence synthesis

Agent-based approaches to literature analysis, structured appraisal and other research-intensive knowledge tasks, with evaluation designed in.

Edge and cloud representation efficiency

Learned interfaces between binary embeddings on constrained hardware and full-precision reasoning in the cloud, assessed on accuracy, latency and energy against quantisation baselines. Early stage.

Training stability under constraint

Constrained-optimisation treatments of drift between training epochs, measured in weight, output or attribution space, aimed at regularising the trajectory without biasing the converged solution. Exploratory.

Early warning from physiological signals

Synthetic corpus generation and time-frequency detection of clinically significant events, evaluated on how early a warning arrives and how often it is wrong.

Trustworthy AI evaluation

Assessment of AI systems across transparency, accountability, robustness, reproducibility, provenance, human oversight and contestability, mapped to European and OECD frameworks.

Research to policy translation

Turning academic evidence and methodological expertise into policy-relevant and industry-relevant concepts across European research and innovation programmes.

Data protection in public registries

The protection consequences of desynchronisation between national registries, where records persist as active long after the underlying activity has ceased.

Skillset

The capability map

Forty-eight documented capabilities across thirteen families. Depth is stated as the highest level evidenced in each family, and where that level is working knowledge rather than delivery experience, it says so.

Expert established practice with external evidence behind it Advanced repeated delivery, independently owned Intermediate practical working experience Working knowledge designed or studied, not yet delivered
Depth is recorded per capability family against documentary evidence. Individual attribution is deliberately omitted from this page.
