Situation Namespace
Core Definition
Situation frames package recurring complex situation types — configurations that involve multiple participants, phases, or sub-events — into a single named frame. Unlike other namespaces that focus on a single semantic primitive (one event, one property, one relation), Situation frames provide a structural scaffold for a recognized scenario: the combination of roles, setting conditions, and typical event sequences that together constitute a familiar situation type.
There is no single formal template; Situation frames use two structural models:
Scenario frames (multi-event configurations):
SCENARIO(Participants..., [Setting], [Phases / Sub-events])
Image-schema frames (spatial primitives):
IMAGE_SCHEMA(Trajector/Figure, Landmark/Ground, [Region])
Key properties of Situation frames:
- Multi-participant: two or more roles are typically required to instantiate the scenario
- Phase-structured: scenarios unfold through recognizable phases or sub-events
- Type-level: Situation frames name a kind of situation, not a specific occurrence; they serve as organizing schemas that other frames inherit from or use as a setting
- Non-reducible: the scenario cannot be decomposed into a single event, attribute, or relation without losing the scenario gestalt
Scope
Includes:
- Scenario frames (Cenário_): named situation types covering social, commercial, institutional, and physical domains
- Image-schema frames (Esquema_imagético_): spatial primitives defining regions and configurational relations between Trajector and Ground
- Conditional / logical structure frames: configurations that define the logical or counterfactual relationship between propositions (Cenário_condicional, Alternatividade, Negação)
- Locative schema frames: source-path-goal schemas and bounded-region schemas used by Transition and Stative frames
Excludes — see other namespaces:
- Single occurrence of a bounded event → Eventive
- Agent-initiated action without scenario packaging → Action / Causative
- Ongoing state or property → Stative / Attribute
- Static connection between two entities → Relational
- Discourse-level communicative act → Pragmatic
Critical boundary — Situation vs. Eventive: An Eventive frame profiles a token of an event type (one instance of selling, arriving, etc.). A Situation frame profiles the structured scenario type itself — the configuration of roles and phases within which eventive frames are embedded. Venda (a selling event) is Eventive; Cenário_comercial (the commerce scenario bundling buyer, seller, goods, payment, and transfer) is Situation.
Subtypes
By frame type:
| Subtype | Definition | Example frames |
|---|---|---|
| Social interaction scenarios | Multi-party interaction with defined roles and phases | Cenário_de_visita, Cenário_comunicativo, Cenário_de_apresentação |
| Commercial scenarios | Transactions involving exchange of goods, services, or money | Cenário_comercial, Cenário_de_aquisição, Cenário_de_transferência |
| Institutional scenarios | Employment, education, and health situations with institutional roles | Cenário_de_emprego, Cenário_educacional, Cenário_de_saúde |
| Legal / Obligation scenarios | Crime, risk, obligation, and legal accountability | Cenário_criminal, Cenário_de_risco, Cenário_de_obrigação |
| Physical / Movement scenarios | Motion, containment, and displacement in physical space | Cenário_de_movimento, Cenário_locativo |
| Sports / Leisure scenarios | Competitive and recreational activity configurations | Cenário_esportivo, Cenário_de_turismo |
| Disaster / Violence scenarios | Harmful events with victim, perpetrator, and consequence roles | Cenário_de_desastre, Cenário_de_violência |
| Conditional / Logical frames | Propositional configurations: conditionals, alternatives, negation | Cenário_condicional, Alternatividade, Negação, Circunstâncias_contrárias |
| Image-schema frames | Spatial primitives: bounded regions, contact, proximity, alignment | Esquema_imagético_de_contato, Esquema_imagético_de_proximidade, Região_delimitada, Região_com_portal, Fonte_caminho_objetivo |
Internal distinction — scenario vs. image-schema:
| Type | Structure | Role in grammar |
|---|---|---|
| Scenario | Role Ă— Phase configuration | Provides thematic setting for embedded eventive frames |
| Image-schema | Trajector Ă— Ground Ă— Region | Provides spatial substrate for Transition, Stative, and Relational frames |
Diagnostic Tests
Test 1 — Multi-phase structure
Does the frame require recognizing a sequence of sub-events or phases to be instantiated?
✓ Cenário_comercial: needs offer → negotiation → payment → transfer → SITUATION
✓ Cenário_de_emprego: needs hiring → employment period → (possible) termination → SITUATION
✗ João vendeu o carro (single transfer event) → NOT SITUATION (Causative/Eventive)
Test 2 — Multi-role requirement
Does the frame require three or more thematically distinct participants or sub-roles?
✓ Cenário_criminal: Perpetrator, Victim, Crime_type, [Authority], [Consequence] → SITUATION
✓ Cenário_educacional: Student, Teacher, Institution, Content, [Certification] → SITUATION
✗ João correu (one participant, one event) → NOT SITUATION (Action)
✗ João tem um carro (two participants, one relation) → NOT SITUATION (Relational)
Test 3 — Type-level framing
Does the frame name a kind of situation rather than a specific token event?
✓ Cenário_de_visita — names the visit scenario type, not a particular visit → SITUATION
✓ Esquema_imagético_de_contato — names the contact relation schema, not one contact event → SITUATION
✗ A Maria visitou o João — tokens a specific visit event → NOT SITUATION (Eventive)
Test 4 — Scaffold test
Does the frame serve primarily as a setting or organizing schema within which other eventive or stative frames are embedded?
✓ Cenário_comercial provides the scaffold; Venda, Pagamento, Transferência are embedded → SITUATION
✓ Fonte_caminho_objetivo provides the path schema for ir, vir, sair, chegar → SITUATION
✗ Venda (buying event) is the embedded frame itself → NOT SITUATION (Eventive)
Test 5 — Non-reducibility
Can the frame be replaced by a single Eventive, Stative, Attribute, or Relational frame without semantic loss?
✓ Cenário_de_saúde (health scenario: patient, provider, condition, treatment, outcome) — cannot reduce to one event → SITUATION
✓ Região_delimitada (bounded region: interior, boundary, exterior — topological primitive) — not an event or property → SITUATION
✗ A porta abriu — fully captured as a single inchoative event → NOT SITUATION (Inchoative)
Comparison with Adjacent Namespaces
| Feature | Situation | Eventive | Action | Stative | Relational |
|---|---|---|---|---|---|
| Primary unit | Scenario / schema type | Token event | Activity | Held state | Dyadic connection |
| Participants required | ≥ 2 (typically ≥ 3) | Varies | 1–2 | 1 | 2 |
| Phase-structured | Yes | No | No | No | No |
| Dynamic | Varies (scaffold) | Yes | Yes | No | No |
| Type-level | Yes | No | No | No | No |
vs. Eventive / Action: Eventive and Action frames profile a single token occurrence of an event or activity. Situation frames profile the type-level scenario within which events occur. Situation frames are typically inherited by or used as the setting for Eventive frames: Cenário_comercial provides the structural context for Compra, Venda, and Pagamento frames.
vs. Stative: Stative frames describe a property or condition holding of an entity. Image-schema frames in the Situation namespace may look stative (they describe spatial configurations) but differ in that they define structural primitives — topological schemas that supply the abstract spatial structure for Stative, Relational, and Transition frames to use.
vs. Relational: Relational frames describe a static connection between two entities. Some Situation frames (especially image-schema frames) also involve two participants (Trajector and Ground). The difference: Relational frames profile the relation holding between specific entities; image-schema frames profile the abstract spatial region or configurational schema that grounds relational meaning across the lexicon.
vs. Pragmatic: Contexto_comunicativo is a Situation frame that provides the communicative setting scaffold for Pragmatic frames. It is classified as Situation (not Pragmatic) because it defines a structural configuration — the participants, channel, and setting of a communicative situation — rather than performing a discourse act itself.
