Enhanced string match matrix generation

A method comprising:

• accessing a first document set that includes a plurality of documents and one or more target documents;
• accessing a second document set including a second document, wherein each respective document of the second document set has a style different from documents of the first document set and each respective document includes:
• respective second document first text content;
• respective second document second text content;
• and
• respective second document image content;
• for each respective document of the second document set:
• extracting a respective extracted string from the respective second document second text content of the respective document;
• generating a respective synthetic string based on the respective extracted string and associated portions of one or both of the respective second document first text content and the respective second document image content;
• and
• assessing a respective similarity between the respective document and at least one document of the first document set based on the respective synthetic string;
• determining to select the one or more target documents from the first document set based on similarity between the one or more target documents and one or more respective synthetic strings associated with the second document;
• generating a string match data structure describing a relationship between the one or more target documents and the second document from the second document set, wherein the string match data structure includes:
• first portions based on one or more second document substrings from the second document;
• and
• second portions based on one or more target document strings from the one or more target documents that correspond to the one or more second document substrings;
• and
• transmitting a request regarding a duplication error, wherein the request includes the string match data structure, and requests initiating a remediation action selected from a group consisting of:
• deletion of a target document, hiding the target document, locking the target document, de-indexing the target document of the one or more target documents from search results, deprioritizing the target document in search results, redirecting links to the target document to the second document, granting privileges associated with the second document, allocating privileges associated with the second document.
