Abstract: A medium storing a program including: classifying vectors of first sentences in a file into each similar vector; generating an inverted index associating a vector of each first sentence with a position of the first sentence on the file; identifying a feature sentence from a second sentences included in a second sentences; specifying similar vectors being vectors similar to a vector of the feature sentence based on the inverted index; specifying, for each similar vector, first transition data indicating transition of vectors at positions before and after the similar vector based on the inverted index; and specifying, from pieces of first transition data obtained by performing the specifying of the first transition data on the similar vectors, transition data similar to second transition data indicating transition of vectors of sentences before and after the feature sentence, to output the transition data as a response of the search query.

Abstract: A non-transitory computer-readable storage medium storing an information processing program that causes at least one computer to execute a process, the process includes calculating a second index indicating a position of an amino acid on a codon file based on a first index indicating positions of a plurality of codons on the codon file with respect to a plurality of codons having different base sequences indicating the same amino acid; identifying positions of amino acid sequences repeatedly expressed in the codon file based on the second index; and specifying each codon sequence corresponding to a position of each amino acid sequence repeatedly expressed in the codon file as a codon sequence having homology.
