摘要： A chronological change prediction system stores a graphical model which an evidence set at a first time is inputted in and outputs information about states of random variables at a second time when a first period has passed from the first time, determines whether to convert each probability distribution in the first evidence set based on a feature value calculated from the probability distributions and/or a feature value calculated from a random variable associated with the probability distributions in the graphical model, converts each probability distribution determined to be converted into a particular state of a random variable corresponding to each probability distribution determined to be converted, creates a second evidence set from the first evidence set by replacing each probability distribution determined to be converted and included in the first evidence set with the first particular state, and inputs the second evidence set to the graphical model.

摘要： Sentence polarity determination is used to assess whether a sentence is an affirmative expression or a negative expression, and is applied for reputation analysis, etc. Polarity determination determines whether an input sentence is affirmative or negative. When some subject is being talked about, it is sometimes desired to determine whether what is being referred to in the sentence is affirmative or negative, rather than the polarity of the sentence per se. The present invention provides a method for determining the polarity of the sentence by applying a recursive polarity rule based on a dependency structure of the sentence, taking into consideration the portion of the sentence that is being referred to. Use of a recursive rule makes it possible to prevent the number of rules from becoming huge, and thereby to perform efficient polarity determination in terms of memory amount and calculation amount. The length of the dependency needed for polarity determination can also be efficiently controlled.

摘要： It is provided an analysis system comprising a processor executing a program and a memory storing the program. The analysis system further comprises a data mapping unit controlling the processor to set an attractive force and a repulsive force acting between the instances based on the similarity information between data, and arranging the instances in a vector space having a certain number of dimensions so that an energy caused by the attractive force and the repulsive force is less than a threshold defined in advance, and a clustering unit classifying the instances arranged in the vector space. The data mapping unit is configured to virtually add one dimension to the vector space, add a minute fluctuation to coordinates of the instances in a direction of the added dimension, and calculate a minimum number of dimensions of the vector space where the instances are stable with respect to the minute fluctuation.
