Abstract

Collected specimens can highlight visitor's understanding of nature and evolutionary history from museum. Thus, museum's physical collection is often used to produce exhibits. However, it is a trend to create physical exhibit and web exhibit concurrently. The purpose is to serve different audiences using different delivery systems. Museum's collections that stored and managed into a large database, termed content databases provide valuable information and data for use in the development of e-learning. The database for specific exhibit can be used as educational resources to providing a full interactive learning experience for students and casual information seekers. However, collision free, no waste of memory space and fast searching are three important factors as searching related specimen from the web. This paper is to propose a new scheme for constructing letter-oriented minimal perfect hashing functions to benefit searching experience, which is based on the Newton's interpolating polynomials.
