THE CLIENT

A Renowned Predictive Audience Insights Firm

Our client is a US-based company that uses machine learning and predictive analytics to study how people consume entertainment content (like trailers, shows, or movies) and how audience preferences are changing. Instead of relying on outdated survey-based research, they utilize AI tools to forecast audience engagement and guide content creators/distributors on how to effectively reach the right viewers.

PROJECT REQUIREMENTS

Large-Scale Multilingual Content Metadata Tagging for AI-Powered Audience Response Prediction Platform

The client sought specialized data labeling services to enhance the accuracy of their machine learning models. The project required resources with a deep knowledge of cinema, storytelling, and genres to ensure high-quality metadata tagging. Our scope of work included assigning precise, context-specific keywords to each storyline, which served as critical inputs for the client’s AI models, enabling the prediction of target audiences.

Essentially, anything that carried a narrative/storyline—whether in video or written form—needed to be annotated with keywords about genre, themes, emotions, characters, and audience appeal. This included -

  • Movie trailers (new releases, upcoming films, festival titles)
  • Full-length feature films (mainstream, indie, international cinema)
  • TV shows and series (ongoing series, cult shows, new pilots)
  • Documentaries (feature-length and episodic formats)
  • Streaming platform originals (exclusive content from Netflix, Amazon, Disney+, etc.)
  • Promotional clips and teasers (short-form video content)
  • Written content metadata (synopses, loglines, episode descriptions)

Our team had to:

  • Assign relevant keywords to over 2500+ movies/series/trailers per month
  • Provide multilingual support (analyzing content across different cultural and linguistic contexts, including Spanish and German)
PROJECT CHALLENGES

Balancing High-Volume Data Labeling with Accuracy and Context Sensitivity

  • Multi-Genre Expertise Requirements: The project demanded comprehensive knowledge across diverse genres, including horror, romance, sci-fi, documentaries, international cinema, and other emerging content formats, requiring team members with extensive entertainment industry awareness as well as genre-specific understanding.
  • Content Uniqueness Complexity: Every story (and hence, the storyline labeling session) was unique. Each TV show or movie had a different plot, requiring a fresh contextual perspective and web research capabilities (to decode plot intricacies, cross-reference cultural references, and validate thematic elements) for relevant data tagging.
  • Strict Turnarounds with Large Volume: CriticalOur team had to meet daily volume targets (80+ content analyses & document tagging per day) while ensuring contextual accuracy. This demanded scalable data labeling workflows with a dedicated team of keyword tagging experts.
  • Multilingual Content Analysis and Labeling: As the content was available in different languages (English, Spanish, German, etc.), data annotators with native-level language expertise were critical for accurately interpreting narratives and assigning culturally and linguistically appropriate keywords to the media.
OUR SOLUTION

Scalable Data Labeling Workflows with Human-in-the-Loop Precision

To meet the client’s requirement of large-scale text data labeling and keyword tagging, we deployed a team of 25 dedicated resources - 20 data labelers(having relevant entertainment industry knowledge and content analysis & web research expertise), 1 German language expert, 1 Spanish language expert, and 3 senior QA analysts.

We followed a multi-layered methodology for accurate content analysis and keyword tagging. The approach involved:

1

Content Analysis and Storyline Deconstruction

Each trailer, synopsis, or show description was broken down into narrative layers:

  • Genre & Sub-Genre: (Action Thriller, Period Drama, Rom-Com)
  • Tone & Mood: (Suspenseful, Dark, Heartwarming)
  • Themes: (Revenge, Survival, Friendship, Justice)
  • Character Archetypes: (Hero, Anti-Hero, Mentor, Villain)

This ensured that annotators fully understood the essence of the content before assigning keywords. Where themes were nuanced or culturally rooted, annotators supplemented content review with web research to cross-check interpretations and refine keyword choices for precise audience targeting.

2

Semantic Keyword Identification

To identify and assign relevant keywords for each content piece, our team utilized a semantic mapping approach. Under this approach, keywords or tags were carefully selected to capture:

  • Explicit Elements: Visible, easily recognizable details of a story that anyone can spot directly by watching a trailer or reading a synopsis. For eg, courtroom drama, space mission, time travel, high-school romance.
  • Implied Aspects: Underlying themes that influence the story but may not be directly stated. For eg, family conflict, power struggle, search for identity.

By assigning both types of tags for each content type, we ensured that the annotated dataset reflected not just what the content was about, but also why it would resonate with specific audiences.

3

Keyword Ontology Framework Development

We developed a keyword ontology framework (organizing key terms into a structured hierarchy of genres, moods, and themes) that served as both a dictionary and a roadmap for content classification. Instead of leaving room for annotators to invent their own terms, this standardized keyword set ensured labeling consistency.

For example, terms like “Detective” and “Investigation” were placed under the broader parent category “Crime/Thriller.” This framework provided a unified reference point, enabling accurate and scalable labeling across thousands of titles.

4

Data Labeling and Human-in-the-Loop Validation

We implemented a multi-tier text, image, and video labeling workflow where initial keyword tagging was followed by peer validation and final review by QA specialists for contextual accuracy.

  • Expert Escalation: Ambiguous cases (e.g., whether a show should be classified as a “satire” or “dark comedy”) were escalated for specialist review.
  • Multilingual Accuracy: For Spanish and German content tagging, native-language experts ensured semantic and cultural alignment, going beyond literal translation to capture narrative intent.
  • Scalable Workflows: We leveraged batch labeling techniques to manage high content inflows (2,500+ shows/movies monthly) without compromising contextual accuracy.
  • Continuous Improvement: Each delivery cycle included feedback integration from the client’s analytics team, allowing us to refine the keyword tagging strategy in sync with evolving AI model requirements.

Data Security Guaranteed at Every Stage

We ensured end-to-end security throughout the data labeling project by implementing strict protocols:

Followed ISO 27001 certified practices for secure data storage, transfer, and access management

Signed NDAs with every resource to guarantee confidentiality

Deployed multi-factor authentication (MFA) and biometric access controls for all team members accessing client content databases

Maintained segregated network environments with VPN-secured connections and real-time monitoring of all data access activities
