​
Why It Matters

Understanding inflation dynamics requires systematic analysis of complex, interconnected factors across the economy. Manually tracking inflation drivers across thousands of news reports, economic data releases, and market commentaries is time-consuming and prone to human bias. As inflation remains a critical concern for policymakers, investors, and analysts, there’s an urgent need for scalable, systematic approaches to monitor inflation themes.

​
What It Does

This workflow is a Macroeconomic Drivers Tracker that breaks down US Inflation into its main components and drivers, then analyzes detailed news reports to extract insights in a structured analytical report. Built for analysts, portfolio managers, and economic researchers, it transforms scattered economic narratives into structured intelligence about inflation dynamics.

​
How It Works

The workflow combines LLM-powered theme taxonomies, semantic content retrieval, and structured reporting methodologies to deliver:
  • Automated theme breakdown into specific inflation components and drivers
  • Systematic document analysis using embeddings-based search and classification
  • Economic categorization that turns narrative signals into structured insights
  • Comprehensive reporting with analytical summaries for each inflation driver

Mindmap a Theme Taxonomy with Bigdata Research Tools

You can leverage Bigdata Research Tools to generate a comprehensive theme taxonomy with an LLM, breaking down a theme into smaller, well-defined concepts or sub-themes for more targeted analysis. In this case we are able to extract the drivers 
theme_tree = generate_theme_tree(
    main_theme=main_theme,
    focus=focus,
)

sentences_query = theme_tree.get_summaries()
label_to_parent_mapping = theme_tree.get_label_to_parent_mapping()
unique_themes = list(set(label_to_parent_mapping.values()))

theme_tree.visualize()

​
Retrieve Content using Bigdata’s Search Capabilities

With the theme taxonomy and screening parameters, you can leverage the Bigdata API to run a search across all the news. 
# Use search_by_any for broad company discovery
df_sentences = search_by_any(
    sentences=sentences_query,
    start_date=start_date,
    end_date=end_date,
    scope=document_type,
    companies=None,  # Open discovery - all companies
    control_entities= source_country,
    freq=freq,
    sort_by=sortby,
    rerank_threshold=rerank_threshold,
    document_limit=document_limit,
    batch_size=batch_size,
    bigdata=bigdata
)

​
Label the Results

Use an LLM to analyze each text chunk and determine its relevance to the inflation sub-themes. Any chunks which aren’t explicitly linked to US inflation components will be filtered out. 
labeler = ScreenerLabeler(llm_model=llm_model)
df_labels = labeler.get_labels(
    main_theme=main_theme,
    labels=list(theme_tree.get_terminal_label_summaries().keys()),
    texts=df_sentences["masked_text"].tolist(),
)

# Merge and process results
df = merge(df_sentences, df_labels, left_index=True, right_index=True)
df = labeler.post_process_dataframe(df)

# Filter out 'Not Applicable' results
df_labeled_extracted = df.loc[~(df.Theme.eq('Not Applicable'))].copy()

# Map the labels to the themes
df_labeled_extracted = df_labeled_extracted.rename(columns={'Theme': 'label'})
df_labeled_extracted['theme'] = df_labeled_extracted['label'].map(label_to_parent_mapping)

​
Text Summarization

This process concatenates all the text for a given label and instructs an LLM to summarize the text retrieved for each driver. The LLM is specifically instructed to generate an analytical summary that is rich in insights and figures, and excludes events and numbers that are outside of the timeframe of the report. 
df_summaries = summarize_topic_by_theme(
    df_labeled_extracted, 
    df_labeled_extracted.theme.unique(),
    df_labeled_extracted.label.unique(), 
    themes_tree_dict= "", 
    api=OPENAI_API_KEY, 
    start_date=start_date, 
    end_date=end_date   
)
In addition, the LLM is instructed to categorize the drivers according to their nature, using specific drivers_tags 
drivers_tags = [
    'Demand-pull: When consumer demand exceeds the available supply of goods and services, driving prices up.', 
    'Cost-push: When production costs like labor or raw materials increase, forcing businesses to raise prices.', 
    'Wage increases: Rising wages can contribute to inflation if businesses pass on those costs to consumers in the form of higher prices.', 
    'Global factors: International commodity price fluctuations and exchange rate changes can impact inflation within a country.', 
    'Monetary policy: Central banks actions, like adjusting interest rates, can influence inflation level'
]

tags_prompt = get_topic_drivers_tag_prompt(main_theme, "\n- ".join(drivers_tags))

df_summaries['id'] = range(len(df_summaries))
prompts = get_prompts(df_summaries, columns=['id', 'theme','topic', 'topic_summary'])

responses_tag = process_request(prompts, tags_prompt, api_key=OPENAI_API_KEY)

df_tag = deserialize_responses(responses_tag)

# Concat the original DataFrame with the labels
df_summaries_tag = pd.merge(df_summaries.reset_index(), df_tag.reset_index(),
                      on='index', how='left').drop('index',axis=1)

​
Generate the Report

As a final step, an LLM uses the last dataframe to generate a brief introduction for the report, summarizing the contents in a few sentences. The report is then formatted and composed by organizing it by the key driver labels defined above and rendering it in HTML format. 
# Create HTML report
intro_section = create_intro_section(df_summaries_tag, OPENAI_API_KEY, main_theme)
html_report = create_html_report(main_theme, start_date, end_date, intro_section, df_summaries_tag)
display(HTML(prepare_html_for_display(html_report)))
Sample HTML report showing inflation drivers categorized by economic type
# Save HTML report to file
html_report_path = f'{output_dir}/United_States_Inflation_Report_2025.html'
with open(html_report_path, 'w') as file:
    file.write(html_report)
print(f"✅ HTML report saved to {html_report_path}")

​
Export the Results

Export the data as Excel files for further analysis or to share with the team. 
# Export data to Excel
try:
    # Create the Excel manager
    excel_manager = ExcelManager()

    # Define the dataframes and their sheet configurations
    df_args = [
        (df_labeled_extracted, "Labeled Inflation Data", (0, 0)),
        (df_summaries, "Topic Summaries", (2, 4)),
        (df_summaries_tag, "Final Tagged Report", (2, 2))
    ]

    # Save the workbook
    excel_report_path = f'{output_dir}/inflation_analysis_results.xlsx'
    excel_manager.save_workbook(df_args, excel_report_path)
    print(f"✅ Excel results exported to {excel_report_path}")

except Exception as e:
    print(f"Warning while exporting to excel: {e}")

Conclusion

The Inflation Tracking workflow provides a comprehensive automated framework for monitoring and analyzing US inflation dynamics across multiple economic dimensions. By systematically combining advanced information retrieval with LLM-powered categorization, this workflow transforms unstructured news data into structured intelligence for economic analysis and decision-making. Through automated analysis of inflation drivers and their economic categorization, analysts can:
  1. Identify Key Inflation Pressures - Systematically discover and quantify the primary drivers of inflation across different economic sectors and categories
  2. Categorize Driver Types - Automatically classify inflation pressures according to established economic frameworks (demand-pull, cost-push, monetary policy, etc.)
  3. Generate Professional Reports - Create comprehensive, evidence-based reports that can inform policy discussions, investment decisions, and economic research
  4. Scale Economic Analysis - Process thousands of news reports and economic commentaries that would be impossible to analyze manually
From conducting macroeconomic research to supporting central bank analysis or building inflation-focused investment strategies, the Inflation Tracking workflow automates the research process while maintaining the analytical depth required for professional economic analysis. The standardized categorization methodology ensures consistent evaluation across time periods and different inflation episodes, making it an invaluable tool for systematic inflation monitoring and analysis.
