## Taskmaster-1 Enriched Dialog Dataset (Combined)
## Overview

This dataset is a combined, enriched version of the self_dialog and woz_dialog splits from the Taskmaster-1 dataset. It consists of multi-turn, human-human and human-simulated conversations with systematic enhancements for machine learning workflows—especially dialog modeling, generation, and fine-grained evaluation.

All conversations are structured in a JSON format with consistent schema and include added semantic, linguistic, and behavioral annotations.

## Enrichments Included
1. Role Embedding
   
Each turn includes a binary role embedding:

[1, 0] for USER

[0, 1] for ASSISTANT

This makes it easier for sequence models to learn speaker turns without relying on string labels.

Use case: Improves model performance in transformer-based dialog agents by allowing role-aware generation and classification.


2. Response Candidates
   
Each user turn is enriched with nb_response_candidates — 2 to 4 plausible assistant responses sampled from the dataset. These are not ground truth but plausible continuations.

Use case: Ideal for retrieval-based dialog training or negative sampling in response ranking tasks.

3. Readability Score
   
Computed using Flesch-Kincaid metrics and other NLP readability formulas. Stored as readability (0–100 scale, higher = easier).

Use case: Enables analysis of language complexity and training adaptive LLMs for education, accessibility, or voice interfaces.

4. Readability Grade Score
   
Stored as readability_score on a U.S. grade level (lower = easier to read). Especially relevant for UX tuning.

Use case: Allows controlling reading level in generation tasks or selecting user-appropriate training samples.

5. Context Embedding
   
Each turn is augmented with a context_embedding vector (384-dim, Sentence-BERT). Represents the semantic context of the turn.

Use case: Enables plug-and-play use with FAISS-based semantic search, response reranking, and memory-augmented generation.

6. Speaker Role Flags
   
An is_user flag is included for each turn (1 = user, 0 = assistant).

Use case: Simplifies filtering, evaluation, or role-specific metric computation.

7. Utterance Length Bucketing
   
Each turn is labeled as:

short (<= 5 tokens)

medium (6–15 tokens)

long (> 15 tokens)

Use case: Enables sampling, curriculum learning, or model analysis across turn complexity.

8. Bigram Overlap with Previous Turn
   
Computed as bigram_overlap_prev (float between 0 and 1). Measures lexical repetition with the preceding utterance.

Use case: Useful for:

Dialogue coherence metrics

Detecting stagnation or repetition in generated responses

Analyzing repair-based utterances

9. Sentiment Polarity
    
Computed using a sentiment analyzer. Stored as sentiment_polarity:

Ranges from –1 (strongly negative) to +1 (strongly positive)

Use case: Enables emotion-aware generation, tone control, or training sentiment-conditioned agents.

10. Format Summary
    
Each conversation has:

dialog_id: Unique identifier

turns: List of enriched utterances

Each turn includes:

{ "speaker": "USER", "text": "I’d like to book a table for 2", "role_embedding": [1, 0], "intent_label": "request", "nb_response_candidates": [...], "readability_score": 4.5, "context_embedding": [...], "readability": 85.6, "is_user": 1, "length_bucket": "medium", "bigram_overlap_prev": 0.2, "sentiment_polarity": 0.1 }

## Suggested Use Cases

Fine-tuning LLMs for goal-oriented dialog

Training dialog state trackers and response rankers

Evaluating model outputs with context-aware metrics

Curriculum learning based on length or readability

Emotion- and intent-conditioned dialog modeling

Semantic retrieval and reranking systems
