Centralized URL commenting service enabling metadata aggregation

A method, including:

• extracting from a plurality of web sites user-generated comment data on web pages of the web sites;
• obtaining access control parameters from the web sites;
• tagging the comment data with:
• identifiers indicating the web sites that the comment data was extracted from,
• universal resource locators (URLs) indicating the web pages that the comment data are on, and
• authors of the comment data;
• storing the comment data in a repository;
• extracting keywords from the comment data;
• normalizing the keywords, said normalizing including
• creating a single normalized keyword for multiple keywords related to the same topic, and
• tagging comment data that include at least one of the multiple keywords with the normalized keyword, such that all comment data that include at least one of the multiple keywords is tagged with the same normalized keyword;
• and
• controlling access to the repository based on the access control parameters, the access to the repository including at least one of read access and write access.

A system comprising:

• an aggregation module for extracting from a plurality of web sites user-generated comment data on web pages of the web sites;
• a registration module for obtaining access control parameters from the web sites;
• a central processing unit (CPU) for tagging the comment data with:
• identifiers indicating the web sites that the comment data was extracted from,
• universal resource locators (URLs) indicating the web pages that the comment data are on, and
• authors of the comment data;
• a repository for storing the comment data;
• a text analyzer for extracting keywords from the comment data and normalizing the keywords to create a single normalized keyword for multiple keywords related to the same topic, the CPU tags comment data that include at least one of the multiple keywords with the normalized keyword such that all comment data that include at least one of the multiple keywords is tagged with the same normalized keyword;
• and
• an access controller for controlling at least one of read access and write access to said repository based on the access control parameters.

A computer program product, including:

• a non-transitory computer readable storage medium;
• first program instructions to extract from a plurality of web sites user-generated comment data on web pages of the web sites;
• second program instructions to obtain access control parameters from the web sites;
• third program instructions to tag the comment data with:
• identifiers indicating the web sites that the comment data was extracted from,
• universal resource locators (URLs) indicating the web pages that the comment data are on, and
• authors of the comment data;
• fourth program instructions to store the comment data in a repository;
• fifth program instructions to extract keywords from the comment data;
• sixth program instructions to normalize the keywords, said sixth program instructions
• create a single normalized keyword for multiple keywords related to the same topic, and
• tag comment data that include at least one of the multiple keywords with the normalized keyword, such that all comment data that include at least one of the multiple keywords is tagged with the same normalized keyword;
• and
• seventh program instructions to control access to the repository based on the access control parameters, the access to the repository including at least one of read access and write access,
• said first program instructions, said second program instructions, said third program instructions, said fourth program instructions, said fifth program instructions, said sixth program instructions, and said seventh program instructions are stored on said computer readable storage medium.
