Also disclosed is a pharmaceutical composition comprising said immunity-inducing agent.

Abstract: An apparatus, method, etc. that in designing of the base sequence of, for example, siRNA, realize high-speed retrieval any genes containing analogous base sequences without omission. Accordingly, retrieval is carried out in such a manner that two partial sequences of given length and any extra part are identified from inputted base sequences, and that hamming distance being the number of corresponding bases incompatible with each other is divided and assigned to the partial sequences and extra part and out of the two partial sequences, one with an assigned number not greater is selected and retrieved.

Abstract: It is intended to efficiently determine a base sequence specifically appearing in an expression gene. For this, providing that the expression gene consists of exons (301) . . . (306) and especially that exon (301) is united with exon (302) and exon (302) with exon (303), an aggregate of base sequences (401) (403) being a union of exon base sequences (301) . . . (305) and a boundary base sequence obtained by uniting together base sequences (404) and (405) and base sequences (406) and (407) respectively existing over boundaries between exon (301) and exon (302) and between exon (302) and exon (303) is formed, and the aggregate is searched. If a base sequence is one specifically appearing in the expression gene, the number of search results is 1 and otherwise, the number is plural.

Abstract: It is intended to support a unique design of a primer. To calculate an indication showing the occurrence frequency of a sequence in a genome sequence, the occurrence frequencies of partial sequences having a definite length in the genome sequences are calculated. Then the occurrence of frequency of each partial sequence of the definite length is stored in an incidence/isolation degree table (16). Concerning each partial sequence of the definite length, a degree of isolation i, which means that j mutation indicating the conversion of j bases (j=<i?1) does not occur in the genome sequence but i mutation indicating the conversion of i bases occurs in the genome sequence, is calculated. Then the degrees of isolation of the partial sequences of the definite length are stored in the incidence/isolation degree table (16).

Abstract: To generate a more preferable regression tree by using two predicative numeric attributes as a rule for splitting. For N.times.M buckets of a plane that has two axes corresponding to two predicative numeric attributes of data in a database, which belongs to one node of a regression tree, the number u(i, j) of data, belonging to a bucket (coordinate (i, j)), and sum v(i, j) of an objective numeric attribute value of data belonging to the bucket are stored. A bucket region which maximizes the interclass variance is segmented from the plane. Nodes are prepared for the data included in the extracted bucket region and for data outside the bucket region.

Abstract: The present application discloses a method and apparatus for extracting association rules from data having two or more numeric attributes and a true-false attribute, and for presenting the rules in an easily understandable form. The method comprises the steps of: (i) storing numbers u(i,j) and v(i,j) of data in each pixel whose true-false attribute is true, so as to correspond to each pixel in a plane; (ii) inputting a condition .theta.; (iii) segmenting from the plane a rectilinear region S of the pixels to maximize the equation ##EQU1## ;and (iv) outputting data included in the segmented rectilinear region S. The invention also allows regions to be derived which satisfy a desired support maximization rule, confidence maximization rule, optimized entropy rule, and optimized interclass variance rule.

Abstract: A method is described for finding correlation between a plurality of data having two kinds of numerical attributes and a true-false attribute. The method comprises the steps of: constituting a plane with two numerical attributes, dividing the plane into meshes, and counting the number of data in each mesh (also called a "bucket") and the number of data whose true-false attribute represents true. If each mesh is assumed to be a pixel, such plane can be considered as a plane image in which the number of data corresponds to brilliance, and the number of data whose true-false attribute represents true corresponds to saturation. The method further includes the step of segmenting an admissible image which is convex along an axis of the plane according to a predetermined condition .theta. to find an area with strong correlation. If the segmented area as the admissible image satisfies the above-described condition such as the maximized support rule, the method also presents the area to the user.
