Abstract: A storage medium storing a program for causing a computer to perform processing including: performing a morphological analysis on a source code to divide the source code into a plurality of reserved words and a plurality of variables; performing, based on a static dictionary defining a relationship between a reserved word and a static code, assigning of the static code corresponding to the reserved word to the reserved word and assigning of a dynamic code to the variable, to thereby generate a compressed code array; registering the variable, the dynamic code assigned to the variable, and an attribute of the variable; calculating a vector of the source code by assigning a predetermined vector to the static code in the array and assigning a vector to the dynamic code in the array by embedding the dynamic code in a vector space based on the attribute corresponding to the dynamic code.
