Phrase Model Site Quality Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internet search engines face challenges in accurately ranking search results due to the lack of reliable site quality scores for all websites, as existing methods are either time-consuming or not applicable to all sites, leading to inconsistent and suboptimal ranking of resources.
Innovation Solution
A system generates a site quality score for new sites by using a phrase model based on relative frequency measures of n-grams, which maps phrase-specific frequencies to baseline site quality scores, allowing for automatic computation of aggregate site quality scores that can be used by search engines for ranking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing site quality scoring methods are used, then site quality scores can be obtained for previously-scored sites, but the methods are time-consuming and not applicable to all sites
Solution Approach 1:
The system enables sites to be automatically scored without human intervention by using machine learning models that process site content, structure, and other attributes autonomously. The phrase model and regression model work together to compute quality scores for new sites without requiring manual evaluation, thus achieving self-service automation that improves productivity while maintaining broad applicability.
Solution Approach 2:
The patent introduces intermediate representations including phrase frequency vectors and site attribute vectors that serve as mediators between raw site data and quality scores. These intermediate representations enable the system to process diverse site types uniformly, bridging the gap between different site formats and the scoring mechanism, thereby improving both computation speed and applicability across all site types.
2Measurement precision
If manual or traditional automated scoring methods are used, then site quality can be assessed, but the process is time-consuming
Solution Approach 1:
The system performs preliminary processing by extracting phrase frequencies, site attributes, and other features before the actual quality scoring. The phrase model pre-processes site content into structured representations that can be quickly evaluated by the regression model. This preliminary action separates data preparation from evaluation, reducing the time required for actual quality assessment while maintaining precision.
Solution Approach 2:
The patent replaces manual or traditional automated scoring mechanisms with machine learning-based models including phrase models and regression models. These computational models automatically analyze site characteristics and generate quality scores without human intervention, substituting mechanical human evaluation with automated algorithms that are both faster and consistently accurate.
3Measurement precision
If comprehensive site analysis is performed to ensure accurate scoring, then quality measurement improves, but system complexity increases
Solution Approach 1:
The system segments the site quality assessment process into distinct components: phrase frequency analysis, attribute extraction, model-based scoring, and result aggregation. Each component handles a specific aspect of quality evaluation independently. This segmentation allows comprehensive analysis to be performed through multiple simple, modular steps rather than one complex monolithic process, maintaining accuracy while managing system complexity.

AI summary
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for predicating a measure of quality for a site, e.g., a web site. In some implementations, the methods include obtaining baseline site quality scores for multiple previously scored sites; generating a phrase model for multiple sites including the previously scored sites, wherein the phrase model defines a mapping from phrase specific relative frequency measures to phrase specific baseline site quality scores; for a new site that is not one of the previously scored sites, obtaining a relative frequency measure for each of a plurality of phrases in the new site; determining an aggregate site quality score for the new site from the phrase model using the relative frequency measures of phrases in the new site; and determining a predicted site quality score for the new site from the aggregate site quality score.
