Remote scoring and aggregating similarity search engine for use with relational databases

A system for performing similarity searching by remote scoring and aggregating, comprising:

• means for receiving a request by a similarity search server from one or more clients for initiating a similarity search, the request designating an anchor document and at least one search document;
• means for generating one or more SQL commands from the client request;
• means for sending the SQL commands from the similarity search server to one or more remote database management systems;
• means for executing the SQL commands in the database management systems to determine normalized document similarity scores using user defined functions;
• means for returning document similarity scores to the similarity search server from the one or more database management systems;
• and
• means for constructing a search result and sending the search result to the one or more clients.

A system for performing similarity searching by remote scoring and aggregating, comprising:

• one or more clients communicating with a similarity search server for requesting a similarity search between an anchor document and at least one search document;
• the similarity search server processing the similarity search request and constructing one or more SQL commands from the similarity search request;
• the similarity search server communicating with one or more database management systems for transmitting the one or more SQL commands;
• the one or more database management systems executing the SQL commands to obtain a similarity search result between the anchor document and the at least one search document;
• the one or more database management systems communicating with the similarity search server for transmitting the search result;
• and
• the similarity search server processing the similarity search result and communicating with the one or more clients for transmitting a similarity search response to the one or more clients.
