Head-to-Head Narrative Dominance

Overview

This pillar analyzes media and social sentiment specifically when two political opponents are mentioned together. It moves beyond general popularity to measure who appears stronger in a direct contrast, a key factor for undecided voters.

What It Does

It isolates media articles, social media posts, and debate transcripts where both candidates are featured prominently. Using natural language processing, it scores the sentiment attributed to each candidate within that shared context. The pillar then aggregates these scores to create a 'Narrative Dominance Index' that tracks which candidate is winning the head-to-head battle for public perception.

Why It Matters

Voters often make decisions based on direct comparisons, especially during debates or when consuming contrastive news coverage. This pillar provides a leading indicator of shifts in head-to-head polling by capturing the subtle dynamics of how one candidate's framing affects the other's.

How It Works

First, the system ingests a high volume of data from news outlets and social media, filtering for content that mentions both primary opponents. Next, a sentiment analysis model evaluates the tone and context surrounding each candidate's mention. These individual scores are then compared and weighted, producing a daily dominance score that shows who is gaining or losing narrative ground against their rival.

Methodology

The core metric is the Narrative Dominance Index (NDI), calculated daily. NDI = (SUM(Sentiment_A) - SUM(Sentiment_B)) / Total_H2H_Mentions within a 72-hour rolling window. Sentiment is scored from -1 to +1 using a fine-tuned BERT model trained on political text. A 'head-to-head mention' is defined as a document where both candidates' names appear within 150 words of each other.

Edge & Advantage

While others track general sentiment, this pillar focuses on the high-stakes context of direct comparison, offering a more precise signal for how competitive matchups will resolve.
