Ontology¶

What This Page Is For¶

This page is the quick reference for the SEGB ontology and the prefixes you will see in Turtle exports, scripts, and UI queries.

Canonical SEGB Ontology Reference¶

Preferred prefix: segb
Namespace IRI: http://www.gsi.upm.es/ontologies/segb/ns#
Human-readable ontology documentation: Semantic Ethical Glass Box (SEGB) Ontology
OWL serialization: [ontology.owl] (https://www.gsi.upm.es/ontologies/segb/ns/doc/ontology.owl)

Prefixes Commonly Used In SEGB Logs¶

The semantic_log_generator package binds a default set of prefixes. These are the ones you will see most often:

Prefix	Namespace IRI
`segb`	`http://www.gsi.upm.es/ontologies/segb/ns#`
`prov`	`http://www.w3.org/ns/prov#`
`oro`	`http://kb.openrobots.org#`
`mls`	`http://www.w3.org/ns/mls#`
`onyx`	`http://www.gsi.upm.es/ontologies/onyx/ns#`
`emoml`	`http://www.gsi.upm.es/ontologies/onyx/vocabularies/emotionml/ns#`
`sosa`	`http://www.w3.org/ns/sosa/`
`schema`	`http://schema.org/`
`oa`	`http://www.w3.org/ns/oa#`
`foaf`	`http://xmlns.com/foaf/0.1/`
`rdf`	`http://www.w3.org/1999/02/22-rdf-syntax-ns#`
`rdfs`	`http://www.w3.org/2000/01/rdf-schema#`
`owl`	`http://www.w3.org/2002/07/owl#`
`xsd`	`http://www.w3.org/2001/XMLSchema#`

The Main Kinds Of Things You Will See¶

You do not need to memorize the whole ontology to work effectively. In practice, most first integrations revolve around these kinds of resources:

robots
humans
logged activities
messages
ML models and evaluation artifacts
emotion analysis results
robot state samples
shared events or shared contexts

Common Modeling Patterns¶

These patterns are the ones you will notice most often in SEGB data.

Activity-Centered Logging¶

SEGB often models an interaction around an activity:

an activity is performed by a robot
a message or result is generated by that activity
timestamps describe when the activity happened

Provenance¶

SEGB relies heavily on provenance-style links so that you can answer questions like:

what produced this message?
which model was used?
what input led to this output?

A Tiny Example¶

This is not a full production example, just a small reading aid:

@prefix segb: <http://www.gsi.upm.es/ontologies/segb/ns#> .
@prefix schema: <http://schema.org/> .
@prefix prov: <http://www.w3.org/ns/prov#> .

<https://example.org/activity/listen_1>
  a segb:LoggedActivity ;
  prov:startedAtTime "2026-03-08T12:00:00Z" .

<https://example.org/message/msg_1>
  a schema:Message ;
  schema:text "Hello ARI" ;
  prov:wasGeneratedBy <https://example.org/activity/listen_1> .

Even in this tiny snippet you can already read the structure:

there is an activity
there is a message
the message was generated by that activity
