WOrd SEntence COoccurrence - Extract and analyze concept associations in creative stories

Wosecopypy: WOrd SEntence COoccurrence

Wosecopypy is a Python package for extracting and analyzing concept associations in creative stories using natural language processing and network analysis. It identifies semantic relationships between concepts across consecutive sentences to understand narrative flow and creativity.

Features

• Bilingual Support: Process both English and German text
• Concept Extraction: Extract noun-based concepts from sentences using spaCy
• Semantic Matching: Link concepts across sentences using word embeddings similarity
• Network Analysis: Build and analyze concept networks with 6 key metrics:
  • Average Shortest Path Length (ASPL)
  • Mean Local Clustering Coefficient (MLCC)
  • Modularity (community structure)
  • Number of Connected Components
  • Average Component Size
  • Giant Connected Component Size
• Creativity Analysis: Measure "unexpectedness" of concepts relative to prompts
• Visualization: Generate network graphs and statistical plots
• CLI Tools: Complete command-line interface for all operations
• Export Formats: GraphML, GEXF, GML for network visualization tools

Quick Start

Command Line Usage

1. Extract Wosecopypy Concepts from Stories

Wosecopypy extract stories.csv -o results.csv --language en --text-column Story

2. Calculate Network Metrics

Wosecopypy metrics results.csv -o metrics.json

6. Compare Multiple Raters

Wosecopypy compare results.csv -r rating_h -r rating_j -r rating_k -o plots/

7. Calculate Unexpectedness Scores

Wosecopypy unexpectedness results.csv --prompt-column prompt -o unexpected.csv

Python API Usage

Basic Concept Extraction

from Wosecopypy import WosecopypyExtractor

# Initialize extractor
extractor = WosecopypyExtractor(language='en', model_size='lg')

# Process a CSV file
df = extractor.process_csv(
    'stories.csv',
    text_column='Story',
    output_path='results.csv'
)

# Or process directly from DataFrame
import pandas as pd
df = pd.DataFrame({'Story': ['Your story here...']})
concepts = extractor.get_Wosecopypy(df)

Build and Analyze Graphs

from Wosecopypy.graph import build_graph, export_graph
from Wosecopypy.metrics import calculate_all_metrics

# Build a concept graph
concepts = ['belief', 'faith', 'church', 'prayer', 'hope']
graph = build_graph(concepts, graph_type='chain')

# Calculate metrics
metrics = calculate_all_metrics(graph)
print(f"Clustering coefficient: {metrics['mlcc']:.3f}")
print(f"Modularity: {metrics['modularity']:.3f}")

# Export graph
export_graph(graph, 'my_graph.graphml', format='graphml')

Analyze Creativity by Ratings

from Wosecopypy.analysis import group_by_rating, compare_raters
from Wosecopypy.metrics import stats

# Group concepts by rating
grouped = group_by_rating(df, rating_column='rating_h')

# Calculate metrics for each rating group
for rating, concept_lists in grouped.items():
    metrics = stats(concept_lists)
    print(f"Rating {rating}: ASPL = {sum(metrics['aspl'])/len(metrics['aspl']):.3f}")

# Compare across multiple raters
rater_metrics = compare_raters(
    df,
    rating_columns=['rating_h', 'rating_j', 'rating_k'],
    concepts_column='Wosecopypy_concepts'
)

Measure Unexpectedness

from Wosecopypy.analysis import unexpectedness_arrays

# Calculate unexpectedness scores
scores = unexpectedness_arrays(
    df,
    prompt_column='prompt',
    concepts_column='Wosecopypy_concepts',
    language='en'
)

df['unexpectedness'] = scores

Visualization

from Wosecopypy.visualization import plot_graph, plot_network_stats

# Visualize a concept network
fig = plot_graph(graph, layout='spring', save_path='network.png')

# Plot network statistics
from Wosecopypy.metrics import stats
metrics = stats(concept_lists)
fig = plot_network_stats(
    metrics,
    title='Network Metrics by Rating',
    save_path='metrics.png'
)

Data Format

Input CSV Format

Your input CSV should have at minimum:

Story,prompt,rating_h
"Once upon a time there was a belief. The faith was strong...","belief-faith-sing",4
"Another story about payment and gloom...","gloom-payment-exist",3

Required columns:

• Text column (default: Story): Contains the story/text to analyze
• Optional: prompt - Prompt words used to generate the story
• Optional: Rating columns (e.g., rating_h, rating_j) - Creativity ratings

Output Format

After extraction, the output CSV includes:

Story,prompt,rating_h,Wosecopypy_concepts
"Once upon a time...","belief-faith-sing",4,"['belief', 'faith', 'church', 'prayer']"

The Wosecopypy_concepts column contains the extracted concept chain as a list.

How It Works

1. Sentence Splitting: Stories are split into sentences (by periods)
2. Noun Extraction: Nouns are extracted and lemmatized from each sentence
3. Concept Matching: Between consecutive sentences, the most semantically similar noun pair is identified using spaCy's word embeddings
4. Chain Building: Matched concepts form a chain representing narrative flow
5. Graph Construction: Concepts become nodes, matched pairs become edges
6. Metric Calculation: Network metrics quantify narrative structure and creativity

Key Metrics

• ASPL (Average Shortest Path Length): Measures how efficiently concepts connect. Lower values suggest tighter narratives.
• MLCC (Mean Local Clustering Coefficient): Measures concept clustering. Higher values indicate tightly grouped concept clusters.
• Modularity: Measures community structure. Higher values suggest distinct conceptual modules.
• Connected Components: Number of separate concept clusters.
• GCC Size: Size of the largest connected concept cluster.

Use Cases

• Creativity Research: Analyze how creative stories differ in their conceptual structure
• Narrative Analysis: Study how concepts flow through narratives
• Educational Assessment: Evaluate student writing for conceptual connectivity
• Content Analysis: Compare semantic structure across different text types
• Computational Linguistics: Study semantic relationships in discourse

Examples

See the examples/ directory for Jupyter notebooks demonstrating:

• Basic concept extraction
• Rating-based analysis
• Multi-rater comparison
• Prompt group analysis
• Visualization techniques
