# Asili ya Utoaji: Mfumo wa Subgraph

## Tatizo

Hivi sasa, utoaji wa wakati wa uondoaji huunda uelekezaji kamili kwa kila
triple iliyoundwa: `stmt_uri`, `activity_uri`, na metadata inayohusiana
ya PROV-O kwa kila ukweli wa maarifa.  Kushughulikia sehemu moja
ambayo hutoa uhusiano wa 20 hutoa triples ~220 za utoaji pamoja na
triples ~20 za maarifa - mzigo wa takriban 10:1.

Hii ni ghali (uhifadhi, uwekaji wa indexi, usambazaji) na pia si sahihi
kimaana. Kila sehemu hushughulikiwa na simu moja ya LLM ambayo hutoa
triples zake zote katika mshono mmoja.  Mfumo wa sasa wa kila triple
huficha hili kwa kuunda udanganyifu wa matukio 20 ya uondoaji
huru.

Zaidi ya hayo, vichakavu viwili vya nne vya uondoaji (kg-extract-ontology,
kg-extract-agent) havina utoaji wowote, na hivyo kuacha pengo katika
njia ya ukaguzi.

## Suluhisho

Badilisha uelekezaji wa kila triple na **mfumo wa subgraph**: rekodi moja
ya utoaji kwa kila uondoaji wa sehemu, inayoshirikiwa na triples zote
zilizozalishwa kutoka sehemu hiyo.

### Mabadiliko ya Dhana

| Zamani | Mpya |
|-----|-----|
| `stmt_uri` (`https://trustgraph.ai/stmt/{uuid}`) | `subgraph_uri` (`https://trustgraph.ai/subgraph/{uuid}`) |
| `statement_uri()` | `subgraph_uri()` |
| `tg:reifies` (1:1, utambulisho) | `tg:contains` (1:wengi, uwezeshaji) |

### Muundo Unaolengwa

Triples zote za utoaji huwekwa katika grafu iliyoitwa `urn:graph:source`.

```
# Subgraph contains each extracted triple (RDF-star quoted triples)
<subgraph> tg:contains <<s1 p1 o1>> .
<subgraph> tg:contains <<s2 p2 o2>> .
<subgraph> tg:contains <<s3 p3 o3>> .

# Derivation from source chunk
<subgraph> prov:wasDerivedFrom <chunk_uri> .
<subgraph> prov:wasGeneratedBy <activity> .

# Activity: one per chunk extraction
<activity> rdf:type          prov:Activity .
<activity> rdfs:label        "{component_name} extraction" .
<activity> prov:used         <chunk_uri> .
<activity> prov:wasAssociatedWith <agent> .
<activity> prov:startedAtTime "2026-03-13T10:00:00Z" .
<activity> tg:componentVersion "0.25.0" .
<activity> tg:llmModel       "gpt-4" .          # if available
<activity> tg:ontology        <ontology_uri> .   # if available

# Agent: stable per component
<agent> rdf:type   prov:Agent .
<agent> rdfs:label "{component_name}" .
```

### Kulinganisha Kiasi

Kwa kila sehemu inayozalisha triples tatu zilizochukuliwa:

| | Zamani (kwa kila triple) | Mpya (subgraph) |
|---|---|---|
| `tg:contains` / `tg:reifies` | N | N |
| Triples za shughuli | ~9 x N | ~9 |
| Triples za wakala | 2 x N | 2 |
| Metadata ya taarifa/subgraph | 2 x N | 2 |
| **Triples tatu za jumla za asili** | **~13N** | **N + 13** |
| **Mfano (N=20)** | **~260** | **33** |

## Upeo

### Wasindikaji ambao Watasasishwa (asili iliyopo, kwa kila triple)

**kg-extract-definitions**
(`trustgraph-flow/trustgraph/extract/kg/definitions/extract.py`)

Hivi sasa huita `statement_uri()` + `triple_provenance_triples()` ndani
ya loop ya kila ufafanuzi.

Mabadiliko:
Hamisha `subgraph_uri()` na `activity_uri()` kabla ya loop
Kusanya triples za `tg:contains` ndani ya loop
Toa kundi la shughuli/wakala/uzalishaji mara moja baada ya loop

**kg-extract-relationships**
(`trustgraph-flow/trustgraph/extract/kg/relationships/extract.py`)

Mfano sawa na ufafanuzi. Mabadiliko sawa.

### Wasindikaji ambao Watasasishwa ili Kuongeza Asili (sasa hayapo)

**kg-extract-ontology**
(`trustgraph-flow/trustgraph/extract/kg/ontology/extract.py`)

Hivi sasa hutoa triples bila asili. Ongeza asili ya subgraph
kwa kutumia mfano sawa: subgraph moja kwa kila sehemu, `tg:contains` kwa kila
triple iliyochukuliwa.

**kg-extract-agent**
(`trustgraph-flow/trustgraph/extract/kg/agent/extract.py`)

Hivi sasa hutoa triples bila asili. Ongeza asili ya subgraph
kwa kutumia mfano sawa.

### Mabadiliko ya Maktaba ya Asili iliyoshirikiwa

**`trustgraph-base/trustgraph/provenance/triples.py`**

Badilisha `triple_provenance_triples()` na `subgraph_provenance_triples()`
Kazi mpya inakubali orodha ya triples zilizochukuliwa badala ya moja
Inazalisha `tg:contains` moja kwa kila triple, kundi la shughuli/wakala lililoshirikiwa
Ondoa `triple_provenance_triples()` ya zamani

**`trustgraph-base/trustgraph/provenance/uris.py`**

Badilisha `statement_uri()` na `subgraph_uri()`

**`trustgraph-base/trustgraph/provenance/namespaces.py`**

Badilisha `TG_REIFIES` na `TG_CONTAINS`

### Hayajajumuishwa katika Upeo

**kg-extract-topics**: wasindikaji wa mtindo wa zamani, hawatumiki kwa sasa katika
  mtiririko wa kawaida
**kg-extract-rows**: hutoa mistari si triples, mfumo tofauti wa
  asili
**Asili ya wakati wa swali** (`urn:graph:retrieval`): suala tofauti,
  tayari hutumia mfumo tofauti (swali/uchunguzi/lengo/muhtasari)
**Asili ya hati/ukurasa/sehemu** (dekoda ya PDF, kichunguzi): tayari hutumia
  `derived_entity_triples()` ambayo ni kwa kila kitu, si kwa kila triple — hakuna
  suala la ziada

## Maelezo ya Utendaji

### Upangaji Upya wa Loop ya Msindikaji

Kabla (kwa kila triple, katika uhusiano):
```python
for rel in rels:
    # ... build relationship_triple ...
    stmt_uri = statement_uri()
    prov_triples = triple_provenance_triples(
        stmt_uri=stmt_uri,
        extracted_triple=relationship_triple,
        ...
    )
    triples.extend(set_graph(prov_triples, GRAPH_SOURCE))
```

Baada ya (mfumo mdogo):
```python
sg_uri = subgraph_uri()

for rel in rels:
    # ... build relationship_triple ...
    extracted_triples.append(relationship_triple)

prov_triples = subgraph_provenance_triples(
    subgraph_uri=sg_uri,
    extracted_triples=extracted_triples,
    chunk_uri=chunk_uri,
    component_name=default_ident,
    component_version=COMPONENT_VERSION,
    llm_model=llm_model,
    ontology_uri=ontology_uri,
)
triples.extend(set_graph(prov_triples, GRAPH_SOURCE))
```

### Saini Mpya ya Msaidizi

```python
def subgraph_provenance_triples(
    subgraph_uri: str,
    extracted_triples: List[Triple],
    chunk_uri: str,
    component_name: str,
    component_version: str,
    llm_model: Optional[str] = None,
    ontology_uri: Optional[str] = None,
    timestamp: Optional[str] = None,
) -> List[Triple]:
    """
    Build provenance triples for a subgraph of extracted knowledge.

    Creates:
    - tg:contains link for each extracted triple (RDF-star quoted)
    - One prov:wasDerivedFrom link to source chunk
    - One activity with agent metadata
    """
```

### Mabadiliko Makubwa

Hii ni mabadiliko makubwa kwa mfumo wa asili ya data. Asili ya data haijatolewa, kwa hivyo hakuna uhamishaji unaohitajika. Msimbo wa zamani wa ⟦CODE_0⟧ /
`tg:reifies` unaweza kuondolewa kabisa.
Msimbo `statement_uri` unaweza kufutwa kabisa.
