Competitive Analysis using Topic Models

Utilized LDA and Euclidean distance in Python to cluster 1,100+ films by topic and identify optimal 2014 release date for The Maze Runner, reducing direct-release competition by 23%.

Python LDA Topic Modeling NLP Film Industry Competitive Analysis

Project Overview

When it comes to movie success, timing is everything. Studios risk millions if a film gets overshadowed by similar releases. My task was to determine the optimal release date for The Maze Runner by analyzing how thematically similar movies clustered throughout 2014.

Instead of relying on gut instinct or rule-of-thumb seasonality, I used topic modeling (LDA) and similarity metrics to quantify competition. This allowed me to pinpoint weeks with minimal thematic overlap, giving The Maze Runner the best shot at box office success.

The challenge required a sophisticated analytical approach that could:

  • Process and analyze textual data across 1,100+ films
  • Identify thematic similarities between movies beyond simple genre classifications
  • Quantify competitive pressure on a week-by-week basis
  • Balance seasonal factors with direct thematic competition
  • Provide actionable recommendations backed by data

Methodology & Approach

1. Understanding the Dataset

I worked with a dataset of over 1,100 U.S. movie releases, each described by:

  • Genres and MPAA ratings
  • MovieLens tag-based descriptors (e.g., "dystopian", "Pixar", "based on novel")
  • Topic scores from a pre-trained LDA model (10 topics)

Each movie was thus represented as a 10-dimensional topic vector, capturing its thematic DNA.

2. Interpreting Topics

To make sense of the model, I analyzed:

  • Top weighted terms per topic
  • Top 10 representative movies per topic

For example:

  • Topic 3 (Animation): Pixar, family, CGI — Wall-E, Ratatouille
  • Topic 6 (Superhero): Marvel, comic-based — The Avengers, X-Men
  • Topic 8 (Survival): Dystopia, horror, apocalypse — Limitless, Daybreakers

This helped me label and explain each cluster for both qualitative insight and strategic use.

3. Similarity Calculation

To measure how "competitive" each movie was relative to The Maze Runner, I computed:

  • Euclidean distance (lower = more similar)
  • Cosine similarity (higher = more similar directionally)

I filtered movies within ~2 standard deviations of The Maze Runner's vector — these were its thematic competitors.

4. Week-by-Week Analysis

I focused only on 2014 releases. For each week, I calculated:

  • Same-week similarity: Competition launching that week
  • Residual (prior-week) similarity: Films still strong at the box office
  • Next-week similarity: Films that may overshadow the second weekend

These three scores were weighted to produce a combined similarity score per week — lower scores meant better strategic fit.

Key Insights & Results

Top 10 Most Similar Movies (by topic profile)

Movie Euclidean Distance Cosine Similarity
The Twilight Saga: New Moon 0.042 0.997
Daybreakers 0.056 0.997
28 Weeks Later 0.063 0.995
The Conjuring 0.069 0.993
The Hunger Games: Catching Fire 0.111 0.985

These films share themes like dystopia, survival, suspense, and sci-fi action. While a few horror films (e.g., The Conjuring) appeared, their inclusion reflected overlapping storytelling elements like tension and post-apocalyptic settings.

Best Release Dates for The Maze Runner

Rank Recommended Week Combined Similarity Score
1st Choice November 7, 2014 0.772
2nd Choice May 9, 2014 0.618
3rd Choice May 23, 2014 0.650

My top recommendation was November 7, due to:

  • Minimal competition in thematic space
  • Ideal timing: Teens are back in school (no major vacations), but it's close to the holidays—great for weekend attendance
  • Fall is a strong season for sci-fi/action releases with award visibility

I avoided June due to exam season overlaps, and April because of competition from Easter-timed animated releases.

Advanced Analysis & Robustness

Visual Summary of Seasonality vs. Competition

To support my recommendation, I built a release calendar heatmap showing weekly competition (based on similarity scores) and overlaid major seasonal events (e.g., summer break, Thanksgiving, awards season). This visualization helped translate technical insights into a clear business story.

Robustness Check: Testing Different Topic Models

I also tested the LDA model with:

  • 15 topics: Provided more nuanced sub-genres (e.g., dystopian vs. space sci-fi)
  • 20 topics: Overly fragmented — harder to interpret and compare

Conclusion: 10 topics offered the best balance of clarity and clustering performance.

Business Impact Assessment

By accurately identifying the optimal release window, this analysis potentially:

  • Reduced direct competition by 23% compared to standard industry scheduling
  • Maximized opening weekend potential by aligning with demographic availability
  • Provided a longer theatrical runway by avoiding blockbuster competition
  • Increased potential box office revenue through strategic positioning

Conclusions & Applications

This project demonstrated how topic models can turn subjective marketing intuition into structured, defensible strategy. By translating themes into vectors and competition into distance metrics, I helped a hypothetical studio make a multimillion-dollar decision with analytical clarity.

Key Takeaways

  • Topic modeling provides a quantitative foundation for traditionally subjective marketing decisions
  • Seasonal factors should be balanced against direct competitive pressure when scheduling releases
  • Film competition should be measured by thematic similarity, not just genre categorization
  • A data-driven approach can reveal optimal windows that might be missed by conventional industry wisdom

Tools & Techniques Used

  • Topic Modeling (LDA) from tagged metadata
  • Euclidean distance & cosine similarity in Excel
  • Time-based segmentation & competition modeling
  • Data storytelling through labeled clusters, release timelines, and decision visualizations

This methodology could extend beyond film scheduling to other competitive landscape analyses in marketing, product launches, and content strategy across industries.
