# dialograph

**Dialograph** is a lightweight Python library for representing, evolving, and traversing dialogue memory as a temporal graph.
It is designed for **proactive dialogue agents**, where reasoning over user preferences, beliefs, and strategies matters more than raw generation.

At its core, Dialograph wraps a dynamic graph structure around typed dialogue memories and provides clean hooks for retrieval, scoring, and long-term evolution.

## Core Concepts

### Nodes

Nodes represent dialogue memory units such as:

* user preferences
* beliefs / facts
* dialogue strategies

Each node carries a **state object** (e.g. `PreferenceState`, `BeliefState`) with confidence and temporal metadata.

### Edges

Edges represent relations between memory units:

* semantic relations (supports, contradicts, elicits)
* dialogue flow dependencies
* strategy activation paths

Edges are directional, weighted, and time-aware.

### Time

Dialograph maintains an internal time counter that allows:

* decay of confidence
* forgetting
* recency-based retrieval

## Installation

For development:
```bash
git clone https://github.com/nabin2004/dialograph.git
```

```bash
cd dialograph
```

```bash
uv venv
```
```bash
source .venv/bin/activate
```

```bash
uv pip install -e .
```

## Quick Example

```python
from dialograph.core.graph import Dialograph
from dialograph.memory.preference import PreferenceState
from dialograph.core.edge import EdgeState

g = Dialograph()

g.add_node(
    "pref_movie",
    state=PreferenceState(
        key="movie_genre",
        value="sci-fi",
        confidence=0.9,
    )
)

g.add_node(
    "belief_stress",
    state=BeliefState(
        proposition="user is stressed about exams",
        confidence=0.7,
    )
)

g.add_edge(
    "belief_stress",
    "pref_movie",
    state=EdgeState(relation="influences")
)
```

## Intended Use Cases

* Proactive dialogue systems
* Emotional support agents
* Preference elicitation
* Strategy planning and reuse
* Dialogue memory research

---

## Status

This project is **under active development**.
APIs may evolve, but core abstractions are expected to remain stable.

---

## Roadmap

* [ ] Path-based retrieval
* [ ] Forgetting thresholds
