Codomain Relationship Measures for Search Authority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Search systems face challenges in distinguishing between high and low authority web pages when multiple web pages link to the same image, as low authority pages often 'hotlink' to popular images, leading to inaccurate search results.
Innovation Solution
The method involves determining codomain relationship measures by calculating the ratio of image links from web pages hosted on one domain to images hosted on another domain, which helps in selecting web pages for search results based on their authority and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple web pages are allowed to link to the same image, then the image becomes more accessible and popular, but low authority web pages can hotlink to popular images without hosting them, reducing search result quality
Solution Approach 1:
The patent introduces an intermediary mechanism (codomain relationship measure) that mediates between image accessibility and search result quality. This measure acts as a filter that allows legitimate hotlinking from related domains while blocking unauthorized hotlinking from unrelated low-authority domains, thus resolving the contradiction between allowing multiple web pages to link to images and maintaining search result quality
2Reliability
If web pages are selected based on domain authority, then search result quality improves, but the system complexity increases due to needing to calculate and compare codomain relationship measures
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing codomain relationship measures for domain pairs before search operations. This allows the search system to quickly retrieve and use pre-computed authority measures without performing complex calculations during actual search operations, thus improving search result quality while minimizing the complexity impact during runtime

AI summary
Methods, and systems, including computer programs encoded on computer-readable mediums, including a method for determining codomain relationship measures between domains pairs. The method includes accessing domain data specifying first and second domains; for each first domain: determining a total number of image links on web pages on the first domain, each image link being a link to an image on a second domain; identifying second domains hosting images to which image links on web pages on the first domain link; for each second domain: determining a number of image links from web pages on the first domain linking to images on the second domain; determining a codomain relationship measure for the first and second domain based on the number of image links from web pages on the first domain linking to images on the second domain and the total number of image links on web pages on the first domain.
