Patent ID: 7062477

Claim:
An information-processing apparatus comprising: computation means for computing an expected value of a response transmitted by a plurality of information-processing terminals in response to each of a plurality of contents transmitted to said information-processing terminals; and select means for selecting some of the plurality of contents to be transmitted to each of said information-processing terminals based on said expected value computed by said computation means for each of said contents, wherein said information-processing terminals comprise at least a pair of terminals used by independent users, each user having independent preferences, wherein said plurality of contents includes user specific information relating to each of said information-processing terminals, wherein said computation means computes said expected value by regular extraction based on a formula, wherein said formula is one of a linear association expression, a nueral network, a signoid function, a rule form of a conditional, a decision tree model, or a statistical technique based on a linear model, a discriminative analysis, a logistic recurssion/regression, or a cluster analysis, wherein said linear association expression is a linear expression of a sum of terms which are each a product of a numerical data denoting each user's independent preferences and a coefficient denoting the plurality of transmitted contents, and wherein said expected value can be expressed as a ratio of a maximum response rate and a minimum response rate.
