# Analyzing 13 Million Opinions Across 48,000 Products A data-driven extraction of sentiment from Reddit and Hacker News communities. - **Source:** [Hacker News: Show HN](https://news.ycombinator.com) - **Published:** 2026-11-02 - **Topic:** [Data & AI](https://brifing.si/c/data-ai) - **Original article:** - **On Brifing:** https://brifing.si/s/3160174c-f518-48fa-9d72-22821dc6d394 ## Aggregated Community Sentiment Data The project aggregates 925,678 mentions across 10,153 distinct entities from 104,240 unique accounts. By focusing on platforms like Reddit and Hacker News, the dataset captures organic user feedback. The primary product categories identified include web frameworks, software utilities, media players, and various browsers, reflecting the technical interests of the source communities. ## Ranking Methodology and Weights The ranking system utilizes a consensus formula defined as (n·s + k·μ) / (n + k). Here, n represents trust-weighted mentions, while s denotes trust and time-weighted sentiment. This mathematical approach balances raw volume with community credibility, ensuring that products with higher engagement receive more accurate representation within their respective categories. ## Filtering Noise and Irrelevance To maintain data integrity, the analysis applies strict filtering criteria. Specifically, 7,597 entries with fewer than three mentions are excluded from the ranking. Additionally, 2,027 single-account entries are hidden to prevent bias from isolated users. These thresholds ensure that the final output reflects broader community consensus rather than individual or outlier opinions. ## Categorical Distribution Analysis The dataset organizes findings into 40 distinct categories, each containing at least three ranked entities. Ranks are assigned internally within these categories, allowing for comparative analysis between similar software tools. This structure helps users identify top-performing products within specific niches, such as development frameworks or browser utilities, based on recent community discourse. ## Temporal Scope of Mentions All data points are derived from mentions occurring within the last 12 months. This temporal constraint ensures that the sentiment analysis remains relevant to current software versions and market trends. By limiting the window, the project avoids stale data, providing a snapshot of how products are perceived in the current technological landscape. ## Trust-Weighted Sentiment Metrics The inclusion of a trust-weighting mechanism is crucial for filtering high-quality discourse from noise. By assigning higher value to contributions from trusted accounts, the model mitigates the impact of spam or low-effort comments. This mechanism is essential when processing large-scale unstructured data from public forums like Hacker News and Reddit. ## Software Ecosystem Insights The dominance of web frameworks, libraries, and developer utilities highlights the technical skew of the source platforms. This dataset serves as a valuable resource for developers and product managers seeking to understand the competitive landscape. It provides a quantitative view of how specific tools are discussed and ranked by their target audiences. ## Significance of Community Consensus This project demonstrates the power of extracting structured insights from massive, unstructured social data. By applying a rigorous mathematical framework to community sentiment, it transforms raw forum discussions into actionable product intelligence. Such data-driven approaches are increasingly vital for understanding market reception and identifying emerging trends in the competitive software industry. ## Sources covering this story - https://www.trustmebro.reviews/r/hackernews — --- _Summary written by Brifing from the original reporting.
