Application: Search device, search method, and recording medium (Patent ID: US20240037129A1)

The patent filed by Casio Computer Co Ltd. describes a search device and method that involves generating search target character strings for wildcard search based on tone-marked pinyin search character strings containing wildcards. The processor acquires character strings with tone indications, generates conversion candidates without tone indications, and compares them to determine matches. The device rearranges tone indications, converts input into XML-type description language, and utilizes character string tables for phonetic representations.

Furthermore, the search device and method involve generating search target character strings by enabling inputs of character strings with tone indications and unknown tone indications. The processor compares these strings with conversion candidates to output comparison results. The patent also includes a recording medium storing a program for implementing the search method on a computer, which involves acquiring, generating, comparing, and outputting search target character strings and conversion candidates. Overall, the invention aims to improve wildcard search functionality based on tone-marked pinyin search strings.
