Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the ability to automatically process and interpret news stories and other content in real-time to predict stock price behavior and investment opportunities, relying heavily on traditional media sources and failing to leverage the predictive power of social media and sentiment analysis.
Innovation Solution
A News Analytics System (NAS) that employs quantitative analysis and natural language processing to assign sentiment scores to news articles, utilizing both traditional and new media sources, including social media, to generate predictive models for stock price behavior and investment strategies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional media sources and manual analysis methods are used, then information processing is simpler and more straightforward, but the system cannot process news content in real-time and lacks predictive capability for stock price behavior
Solution Approach 1:
The patent replaces manual mechanical analysis methods with automated computational systems. Natural language processing algorithms automatically parse news articles, extract entities, and determine sentiment, eliminating the need for human analysts to manually read and interpret each news item. This substitution enables real-time processing of vast volumes of news content while maintaining systematic consistency in analysis.
Solution Approach 2:
The patent introduces multiple intermediary components between raw news data and investment decisions. These include entity extraction modules that identify companies and events, sentiment analysis engines that quantify tone, and predictive modeling systems that translate sentiment into price predictions. These intermediaries break down the complex task of news analysis into manageable sequential steps, enabling real-time processing.
2Measurement precision
If comprehensive news coverage from multiple sources is analyzed, then prediction accuracy improves, but the volume of information to be processed increases dramatically
Solution Approach 1:
The patent extracts only the essential and relevant information from news articles using entity extraction and event detection algorithms. Instead of analyzing every word of every news item, the system identifies and extracts key entities (companies, products, events) and their relationships, filtering out redundant information. This extraction approach maintains prediction accuracy by focusing on critical information while dramatically reducing the processing burden.
Solution Approach 2:
The patent segments news analysis into distinct modular components: source identification, entity extraction, event detection, sentiment analysis, and predictive modeling. Each segment processes specific aspects of news content independently and passes results to the next segment. This segmentation enables parallel processing of multiple news sources simultaneously, handling large information volumes efficiently while maintaining comprehensive analysis.
3Reliability
If sentiment analysis and predictive modeling are implemented, then investment decision quality improves, but the computational resources and processing time required increase
Solution Approach 1:
The patent performs preliminary sentiment analysis and entity extraction on news articles as they are being collected, before full predictive modeling is applied. This preliminary processing pre-computes sentiment scores and identifies key entities in advance, so that when predictive modeling needs to be executed, the foundational analysis is already complete. This reduces the computational burden during critical prediction moments while maintaining decision quality.
Solution Approach 2:
The patent applies sentiment analysis and predictive modeling selectively rather than uniformly to all news content. The system prioritizes analysis for news articles that contain relevant entities or exhibit high sentiment intensity, applying full computational resources only where most impactful. This partial action approach maintains investment decision quality for critical cases while reducing overall computational resource consumption.
Data Source
AI summary
The present invention provides a method, system and software that provide a predictive model responsive to the correlation of news articles to stock price movement. The invention analyzes the derivative or ratio of events to drive predictions in a responsive manner. The invention considers derivatives or ratios of news meta-data within a small window in the past relative to a larger window of news items in the past. The invention may use a sentiment engine and apply the derivative of sentiment to predict volatility and/or trend direction of price of a security. The invention may look to the content, context, and derivative of sentiment to weigh news stories according to a predetermined taxonomy factoring in recency, criticality, repeatedness, trustworthiness, etc. to predict stock price behavior. Also, the invention may be used to forecast events given stock price movement and news to predict an impending story or release of significance.
