A new method of recording and searching information (1953)
Fermat's Library explores Hans Peter Luhn's method for organizing information using descriptive metadata called "legends." Luhn's system enhances search accuracy by linking terms and normalizing language, improving information retrieval efficiency.

Fermat's Library discusses Hans Peter Luhn's innovative method for recording and searching information, focusing on the concept of a "legend" as descriptive metadata for documents. Luhn's approach aims to visualize relationships between terms and improve information retrieval by balancing specificity and findability. He suggests using broader terms and multiple descriptors to enhance matching between recorders and inquirers. The system involves a combinatorial calculation resulting in 75 million patterns for selecting terms from a set. A key component is a specialized dictionary that normalizes terminology by mapping specific terms to broader key terms, reducing mismatches in language usage. This method allows a single term to be linked to multiple key terms, enhancing nuanced representation and search accuracy. By broadening concepts and employing redundancy, Luhn's system minimizes variations in language and improves the efficiency of information retrieval processes. The approach is designed to provide responses to inquiries even when the reference seems remote, ensuring comprehensive search results and facilitating the discovery of relevant information.
