# HOEMMA – Human Library Ruhr · Projektdokumentation
|
||||
|
||||
> **Stand:** 15.07.2026
|
||||
> **Projekt:** HOEMMA – KI-basierter Gesprächsbegleiter der Machbarschaft Borsig11 (Dortmund)
|
||||
> **Stack:** Spring Boot 3.5.7 · Java 17 · PostgreSQL + pgvector · Azure AI Foundry (Mistral, Cohere-Embedding, GPT-5-Agent)
|
||||
|
||||
---
|
||||
|
||||
## 1. Was das System macht (Überblick)
|
||||
|
||||
HOEMMA ist ein **RAG-System (Retrieval-Augmented Generation)**, das:
|
||||
|
||||
1. **Interviews & Dateien aus Humbee holt** (Word/.docx, .txt),
|
||||
2. die Transkripte per **Mistral bereinigt** (Sprecherlabels & Zeitstempel entfernen),
|
||||
3. den Text in **Chunks** zerlegt,
|
||||
4. für jeden Chunk ein **Embedding** (Cohere `embed-v4.0`) berechnet und in **pgvector** speichert,
|
||||
5. bei einer Nutzerfrage die **semantisch nächsten Chunks** sucht,
|
||||
6. bei fehlendem lokalem Kontext eine **Web-Suche** (Azure-Agent, GPT-5) auslöst,
|
||||
7. die Antwort im **HOEMMA-Charakter** (warm, Ruhrgebiet-Ton, „Du") per Mistral formuliert.
|
||||
|
||||

|
||||
|
||||
## 2. Architektur / Datenfluss
|
||||
|
||||
```
|
||||

|
||||
Humbee (Interviews) │ POST /knowledge-base/build │

## 3. Wichtige Komponenten
|
||||
|
||||
| Klasse | Aufgabe |
|
||||
|---|---|
|
||||
| `HumbeeController` | `POST /knowledge-base/build` – stößt den Import an |
|
||||
| `HumbeeService` | Login, Datei-Links extrahieren, herunterladen, `buildKnowledgeBase()` (parallel) |
|
||||
| `PromptService` | Transkript-Bereinigung via Mistral (chunk-parallel) |
|
||||
| `DocumentChunckService` | Text in Chunks zerlegen (chunkSize, overlap) |
|
||||
| `DocumentStorageService` | Chunks + Embeddings speichern (`input_type=document`) |
|
||||
| `AzureEmbeddingService` | Cohere `embed-v4.0` Aufruf, unterstützt `input_type` |
|
||||
| `AzureMistralService` | Chat-Completion (Mistral) mit Retry auf 429 |
|
||||
| `RagService` | Kern der Frage-Antwort-Logik (Embedding → Suche → Schwelle → Antwort) |
|
||||
| `AzureWebSearchAgentService` | Web-Recherche über Foundry-Agent (GPT-5), Managed/CLI-Identity |
|
||||
| `SearchController` | `GET/POST /chat/ask` |
|
||||
|
||||
---
|
||||
|
||||
## 4. Gelöste Probleme (Chronik)
|
||||
|
||||
### 4.1 Azure Mistral 429 (Too Many Requests)
|
||||
- **Ursache:** Ganzes Transkript in einem Request + ungedrosselte Parallel-Schleife.
|
||||
- **Lösung:** Chunking vor dem LLM-Call, Drosselung/`sleep`, Retry mit Backoff, `.onRetryExhaustedThrow` (Original-Fehler durchreichen statt „Retries exhausted").
|
||||
|
||||
### 4.2 Langsame Verarbeitung
|
||||
- **Ursache:** Zu kleine Chunks (viele Calls) + sequenzielle Verarbeitung.
|
||||
- **Lösung:** Größere Chunks, Parallelisierung auf **Datei-Ebene** (`buildKnowledgeBase`) und **Chunk-Ebene** (`PromptService`), da die meisten Dateien nur 1 Chunk haben.
|
||||
|
||||
### 4.3 pgvector: „column embedding is of type vector but expression is of type bytea"
|
||||
- **Ursache:** `hibernate-vector`-Dependency fehlte in `pom.xml`.
|
||||
- **Lösung:** `org.hibernate.orm:hibernate-vector` (Version `${hibernate.version}`) ergänzt.
|
||||
|
||||
### 4.4 „Unable to access lob stream"
|
||||
- **Ursache:** `@Lob` auf `String`-Feldern (`Document.rawText/cleanText`) + Lesen außerhalb einer Transaktion.
|
||||
- **Lösung:** `@Lob` entfernen, nur `@Column(columnDefinition = "TEXT")`; Suche `@Transactional(readOnly = true)`.
|
||||
|
||||
### 4.5 Chunk-Text enthielt Zahlen statt Text (z. B. 25569)
|
||||
- **Ursache:** `@Lob` auf `DocumentChunck.chunckText` → PostgreSQL speicherte die **OID** eines Large Objects (eine Zahl), nicht den Text.
|
||||
- **Lösung:** `@Lob` vom Text-Feld entfernen → echter Text wird gespeichert.
|
||||
|
||||
### 4.6 .txt-Dateien: unlesbarer Text mit Leerzeichen zwischen jedem Zeichen
|
||||
- **Ursache:** Dateien in **UTF-16**, als UTF-8 gelesen.
|
||||
- **Lösung:** `decodeBytes(byte[])` – BOM-Erkennung (UTF-8 / UTF-16LE / UTF-16BE) + Heuristik.
|
||||
|
||||
### 4.7 Web-Suche-Agent: Authentifizierung
|
||||
- **422 „Missing api-version"** → api-version bzw. korrekten `/openai/v1/responses`-Pfad geklärt (kein `v1` im Modell-Call).
|
||||
- **401 „audience incorrect"** → Scope; per `jwt.ms` bestätigt: `aud = https://ai.azure.com`. Scope `https://ai.azure.com/.default` ist korrekt.
|
||||
- **Lokal:** `az login` nötig; Eclipse/Spring Tools sieht `az` nur mit angepasstem `PATH` (Run Config → Environment) oder Start aus Terminal.
|
||||
- **Container in Azure-VM:** Managed Identity via `--network host` **oder** Service Principal (`AZURE_TENANT_ID/CLIENT_ID/CLIENT_SECRET`).
|
||||
|
||||
### 4.8 429 „gpt-5-mini exceeded rate limit" beim Build (obwohl Mistral konfiguriert)
|
||||
- **Ursache:** In `AzureMistralService` war das Modell **hart codiert** als `"gpt-5-mini-datazone"` (statt `deployment`), zusätzlich `reasoning_effort` und `max_completion_tokens` (GPT-5-Parameter).
|
||||
- **Lösung:** `"model", deployment` + `"temperature", 0.5` + `"max_tokens", maxTokens`.
|
||||
|
||||
### 4.9 Passwort / .env auf dem Server
|
||||
- **Ursache:** `.env` wird von Spring **nicht** automatisch gelesen (keine dotenv-Dependency).
|
||||
- **Lösung:** Secrets als echte **Umgebungsvariablen** setzen (Docker `-e`, Azure App Settings). `.env` gehört **nicht** nach `src/main/resources` (landet im JAR).
|
||||
|
||||
---
|
||||
|
||||
## 5. Prompt-Integration (v2.0)
|
||||
|
||||
- **system-Message:** statische Rolle & Regeln (HOEMMA-Charakter, Sicherheits-/Datenschutzregeln, Quellenhierarchie).
|
||||
- **user-Message:** dynamischer, **gekapselter** Laufzeitkontext:
|
||||
|
||||
```text
|
||||
<runtime_context> current_date, channel, is_first_contact, address_mode=Du, ... </runtime_context>
|
||||
<retrieved_context> ...Chunks aus der DB... </retrieved_context>
|
||||
<web_results_optional> ...oder "Kein Webkontext verfuegbar." </web_results_optional>
|
||||
<current_user_message> ...Nutzerfrage... </current_user_message>
|
||||
```
|
||||
|
||||
- **Parameter:** `temperature = 0.5`, `max_tokens = 350`, Ansprache **durchgehend „Du"**.
|
||||
- Kapselung schützt zusätzlich vor **Prompt Injection** (Inhalte = nur Informationsquelle, nie Anweisung).
|
||||
|
||||
---
|
||||
|
||||
## 6. Wissensbasis: atomare Fakten-Dateien
|
||||
|
||||
Statt einer Sammeldatei → **eine Datei = ein Thema = ein sauberer Chunk**:
|
||||
|
||||
- `Borsig11_Oeffnungszeiten.docx`
|
||||
- `Borsig11_Adresse.docx`
|
||||
- `Borsig11_Kontakt.docx`
|
||||
- `Borsig11_UeberUns.docx`
|
||||
- `HOEMMA_UeberDasProjekt.docx`
|
||||
|
||||
**Grund:** Eine gemischte Datei ergibt ein „verwässertes" Embedding → schlechte Treffer. Atomare Chunks matchen die jeweilige Frage viel schärfer.
|
||||
|
||||
---
|
||||
|
||||
## 7. Offenes Thema: Retrieval-Distanzen
|
||||
|
||||
`input_type` (`query` / `document`) ist jetzt korrekt implementiert (das Deployment akzeptiert nur `text`, `query`, `document`), **verbessert die Distanzen aber nur gering**:
|
||||
|
||||
| Frage | bestDistance | Status |
|
||||
|---|---|---|
|
||||
| Wie sind eure Öffnungszeiten? | 0.57 | ✅ true |
|
||||
| Wann habt ihr geöffnet? | 0.67 | ❌ false → Web |
|
||||
| Kann ich morgen um 9 Uhr vorbeikommen? | 0.66 | ❌ false → Web |
|
||||
|
||||
**Nächste, wirksamere Schritte:**
|
||||
1. **Fakten-Dateien mit Frage-Varianten anreichern** (z. B. „Wann habt ihr geöffnet?", „um 9 Uhr vorbeikommen", „vormittags") → senkt die Distanz real.
|
||||
2. **Schwelle moderat anheben** (`DISTANCE_THRESHOULD = 0.68`) – lokale Fragen (0.57–0.67) greifen, externe (Borsig11 ~0.77) gehen weiter an die Web-Suche.
|
||||
3. Web-Agent funktioniert als Fallback zuverlässig (200 OK, ~10 s).
|
||||
|
||||
---
|
||||
|
||||
## 8. Wichtige Endpoints
|
||||
|
||||
| Methode | Pfad | Zweck |
|
||||
|---|---|---|
|
||||
| `POST` | `/knowledge-base/build` | Import & Verarbeitung aller Humbee-Dateien |
|
||||
| `GET`/`POST` | `/chat/ask?question=...` | Frage stellen (RAG + ggf. Web) |
|
||||
| `POST` | `/interview/transcription` | Audio → Text (Azure Speech) |
|
||||
| `POST` | `/interview/save` | Interview als .docx erzeugen, hochladen, verarbeiten |
|
||||
|
||||
---
|
||||
|
||||
## 9. Rebuild-Prozedur (bei Embedding-Änderungen)
|
||||
|
||||
Immer **komplett neu aufbauen**, sonst mischen sich alte/neue Embeddings:
|
||||
|
||||
```sql
|
||||
DELETE FROM document_chunck;
|
||||
DELETE FROM document;
|
||||
```
|
||||
```
|
||||
Anwendung: Stop → Clean → Run
|
||||
POST /knowledge-base/build
|
||||
```
|
||||
Empfohlen für pgvector-Performance:
|
||||
```sql
|
||||
CREATE INDEX ON document_chunck USING hnsw (embedding vector_cosine_ops);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 10. TODO vor Produktivbetrieb
|
||||
|
||||
- [ ] **Debug-Ausgaben entfernen** (`System.out.println`: Key, `>>> MODELL`, `root =`, `$$$`, `EMBED …`).
|
||||
- [ ] **Mistral-API-Key rotieren** (war im Log sichtbar).
|
||||
- [ ] **Secrets** aus dem Code/`.env` → Umgebungsvariablen / Azure Key Vault.
|
||||
- [ ] `spring.jpa.hibernate.ddl-auto` von `update` auf **`validate`** stellen.
|
||||
- [ ] **TestController** entfernen oder absichern; Logging auf `INFO`.
|
||||
- [ ] **Managed Identity** (Azure) statt `az login` für den Web-Agent.
|
||||
- [ ] Vollständigen **HOEMMA-System-Prompt** (Demenz, Notfälle, Datenschutz) einsetzen.
|
||||
- [ ] Doppelte `.txt.txt`-Dateien in Humbee bereinigen.

# HOEMMA – Wissensbasis: Basisfakten-Plan
|
||||
|
||||
Stand: 15.07.2026 — Problem: Fragen zu Öffnungszeiten/Adresse erreichen die
|
||||
lokale Wissensbasis nicht (bestDistance 0.61–0.70 > Schwelle 0.60) und laufen
|
||||
teuer über die Websuche. Lösung: atomare Fakten-Dateien (ein Thema = eine Datei
|
||||
= ein reiner Chunk).
|
||||
|
||||
---
|
||||
|
||||
## Schritt 1: Alte Sammeldatei aus der Datenbank entfernen
|
||||
|
||||
```sql
|
||||
-- IDs der Chunks der alten Sammeldatei finden und löschen:
|
||||
DELETE FROM document_chunck
|
||||
WHERE document_id = (SELECT id FROM document WHERE source_url ILIKE '%basisfakten%');
|
||||
|
||||
DELETE FROM document
|
||||
WHERE source_url ILIKE '%basisfakten%';
|
||||
```
|
||||
|
||||
*(Sonst konkurriert die alte Misch-Datei mit den neuen atomaren Dateien.)*
|
||||
|
||||
---
|
||||
|
||||
## Schritt 2: Fünf atomare Word-Dateien erstellen
|
||||
|
||||
Jede Datei in Word anlegen, NUR den jeweiligen Text einfügen, als .docx
|
||||
speichern und in den Humbee-Projektordner hochladen.
|
||||
|
||||
### Datei 1: `Borsig11_Oeffnungszeiten_AKTUELL.docx`
|
||||
|
||||
```
|
||||
Wann ist das Büro geöffnet? Wie sind die Öffnungszeiten von Borsig11?
|
||||
(AKTUELL, Stand: Juli 2026)
|
||||
|
||||
Die offiziellen aktuellen Öffnungszeiten des Büros der Machbarschaft Borsig11:
|
||||
Montag bis Freitag von 11 bis 16 Uhr, sowie nach Vereinbarung.
|
||||
Vor 11 Uhr ist das Büro geschlossen. Wer morgens früher kommen möchte,
|
||||
sollte vorher telefonisch einen Termin vereinbaren.
|
||||
Hinweis: Ältere Artikel auf der Website nennen teilweise veraltete
|
||||
Öffnungszeiten (zum Beispiel aus dem Jahr 2021). Maßgeblich sind die hier
|
||||
genannten aktuellen Zeiten: Montag bis Freitag, 11 bis 16 Uhr.
|
||||
```
|
||||
|
||||
### Datei 2: `Borsig11_Adresse_AKTUELL.docx`
|
||||
|
||||
```
|
||||
Wo befindet sich Borsig11? Adresse und Anfahrt (AKTUELL, Stand: Juli 2026)
|
||||
|
||||
Die Machbarschaft Borsig11 e.V. befindet sich in der Flurstraße 10,
|
||||
44145 Dortmund. Das Büro liegt in der Dortmunder Nordstadt, direkt am
|
||||
Borsigplatz, in den Gemeinderäumen der Heiligen Dreifaltigkeits-Kirche
|
||||
(der BVB-Gründerkirche). Wer uns besuchen möchte: Flurstraße 10,
|
||||
44145 Dortmund.
|
||||
Hinweis: Bis Ende 2020 war das Büro am Borsigplatz 9 — diese alte Adresse
|
||||
gilt nicht mehr.

||||
```
|
||||
|
||||
### Datei 3: `Borsig11_Kontakt.docx`
|
||||
|
||||

```
|
||||
Was ist die Machbarschaft Borsig11? Wer seid ihr?
|
||||
|
||||
Die Machbarschaft Borsig11 e.V. ist ein gemeinnütziger Verein in der
|
||||
Dortmunder Nordstadt am Borsigplatz. Der Verein macht Kultur- und
|
||||
Nachbarschaftsprojekte mit und für die Bewohnerinnen und Bewohner des
|
||||
Borsigplatz-Quartiers — zum Beispiel die Nordstadt Sessions (offene
|
||||
Musikabende), kreative Workshops, die Givebox (Tauschregal), das
|
||||
Schach-Café, die Schneiderei 103 und den Vollmond Talk.
|
||||
```

||||
|
||||
### Datei 5: `HOEMMA_UeberDasProjekt.docx`
|
||||
|
||||
```
|
||||
Was ist HOEMMA? Was ist die Human Library Ruhr?
|
||||
|
||||
HOEMMA – Human Library Ruhr ist ein Projekt der Machbarschaft Borsig11.
|
||||
HOEMMA ist ein KI-basierter Gesprächsbegleiter, der Erinnerungen,
|
||||
Geschichten und Erfahrungen von Menschen aus Dortmund und dem Ruhrgebiet
|
||||
sammelt und für Seniorinnen und Senioren zugänglich macht. Der Name kommt
|
||||
vom Ruhrgebiets-Ausdruck "Hömma!" ("Hör mal!").
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Schritt 3: Einlesen
|
||||
|
||||
```
|
||||
GET http://localhost:9192/knowledge-base/build
|
||||
```
|
||||
|
||||
Prüfen, dass 5 neue Dokumente angelegt wurden:
|
||||
|
||||
```sql
|
||||
SELECT id, source_url FROM document
|
||||
WHERE source_url ILIKE '%oeffnungszeiten%'
|
||||
OR source_url ILIKE '%adresse%'
|
||||
OR source_url ILIKE '%kontakt%'
|
||||
OR source_url ILIKE '%ueberuns%'
|
||||
OR source_url ILIKE '%ueberdasprojekt%';
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Schritt 4: Testfragen (Postman, POST /chat/ask)
|
||||
|
||||
| Frage | Erwartung |
|
||||
|---|---|
|
||||
| Wie sind eure Öffnungszeiten? | bestDistance deutlich niedriger, `true`, Antwort 11–16 |
|
||||
| Wann habt ihr geöffnet? | dito |
|
||||
| Kann ich morgen um 9 Uhr vorbeikommen? | "Büro öffnet erst um 11" |
|
||||
| Bis wann ist das Büro heute offen? | "bis 16 Uhr" |
|
||||
|
||||
Log-Zeile je Frage notieren: `bestDistance … hatRelevantenKontext …`
|
||||
|
||||
---
|
||||
|
||||
## Falls Distanzen knapp über 0.60 bleiben
|
||||
|
||||
Schwelle in `RagService` moderat anheben (z. B. 0.65) — jetzt vertretbar,
|
||||
weil der 2021-Chunk annotiert ist (VERALTET-Hinweis) und die atomaren
|
||||
Chunks die nächsten Treffer sind.
|
||||
|
||||
---
|
||||
|
||||
## Zukunftsaufgabe (systemische Verbesserung, ~1 Tag)
|
||||
|
||||
**Cohere `input_type` einführen** (asymmetrisches Embedding):
|
||||
|
||||
- `AzureEmbeddingService.createEmbedding(text, inputType)` — Request um
|
||||
`"input_type": "query"` bzw. `"document"` erweitern
|
||||
- `RagService` (Nutzerfrage) → `"query"`
|
||||
- `DocumentStorageService` (Chunks) → `"document"`
|
||||
- Danach: ALLE Embeddings neu berechnen (Build + Ingest erneut ausführen)
|
||||
|
||||
Erwarteter Effekt: global bessere/niedrigere Distanzen im ganzen System.
