In this research, as a basis of studies regarding when certain works were written, an estimation was attempted using the works of Ryunosuke Akutagawa. In the experiment, two types of data sets were created from the text with part-of-speech tagging, and a comparative analysis was performed using three methods: Linear Regression, Support Vector Regression, and Random Forest Regression. As a result, when the works were written was estimated with rather high accuracy. The average of absolute value of estimation error and standard deviation was approximately 1.4 years. The order of high accuracy of estimation was Random Forest Regression, Support Vector Regression, and Linear Regression.

Identifying the elements that make up an author's characteristic writing style is one of the keys to determining the authorship or authenticity of a literary composition. The present study, which constitutes a preliminary attempt to uncover such a key, focuses on the placement of commas in sentences, a matter that has hitherto been neglected, analysing the characters that commas follow in works by four authors. It is concluded that the placement of commas differs from writer to writer and may therefore be considered one of the features that makes up an individual literary style, thus providing valuable information for verifying authenticity and speculating on questions of authorship.

This paper proposes a method for authorship identification based on phrase patterns that occur in the Japanese language, using literary work, student's work, journals to carry out actual proof analysis. The results showed that a writer's writing characteristics could be told clearly in phrase patterns. Using Random Forests, the correct ratio for identifying the authors from two arbitrary authors of literary works as well as student compositions was 99% and 92% for journals. In order to show the effectiveness of the proposed method, a comparison between phrase patterns and trigram of POS was conducted. There was no obvious difference found in the rate of correct identification of writer between phrase patterns C and POS trigram. However, when the data of the phrase patterns C were combined with morphological data, it can obtain a higher rate of correct identification of the writer than having combined the data of POS trigram with morphological data. Based on this, we carried out an analysis on the authorship doubt surrounding Kawabata Yasunari's works and the works of Mishima Yukio, HMakoto and Sawana Hisao. Phrase patterns analysis suggested there was no doubt surrounding the authorship in Kawabata's work.

Text classification results often vary depending on the detailed factors in data analysis, including feature data, classification method, and parameter sets adopted in the analysis. The author of an anonymous text can be generally identified by extracting a set of distinctive features of the text, and then using the features to find the most likely author. Numerous efforts have been made to develop the feature extraction technique with more robustness and the classification algorithm, but an important issue is how to select the features datasets and classification method. To address this issue, we propose an integrated classification algorithm that extracts multiple feature datasets from differing viewpoints and aspects of a text and applies multiple strong classifiers to the datasets. Our proposed method achieved 100% accuracy in identifying the authors of literary works and student essays, and identified the author of all but 1 out of 60 diaries which were written by 6 different people.Our proposed method achieved equivalent or better accuracy than the case when any a strong classifier applied to individual feature dataset. Furthermore, the accuracy in identifying the authors of student essays increased by roughly two percentage points.

The varimax rotation, a special case of the orthomax method, usually contains the process of normalization by the communalities of manifest variables. After rotation, factor loadings are re-scaled so that the communalities have original values. Although the standard errors of rotated factor-loadings have been discussed from the general view point of estimation of parameters with restrictions, the actual standard errors for normalized rotation have not been provided. In this paper a method of estimating the asymptotic standard errors in the normalized orthomax rotation is given. Two artificial examples are provided in which standard errors become extremely large with or without normalization.

This article examines characteristics of Japanese public opinion surveys during 1990-2009 and makes pertinent comparisons with the past. Public opinion surveys continued to increase with cities being the major contributor to that growth. Surveys conducted face-to-face and those that used drop self-administered questionnaires decreased, whereas mail surveys increased. Telephone surveys remained a relatively minor method, but increased substantially compared to before 1990. The use of Voter Registration Lists decreased; whereas there were increases in surveys that sampled either from the Basic Resident Registers or did not employ lists. For the 1990-09 period as a whole, the median response rate was 58.9% which suggests a steeper decline than the decreases observed in the past. Surveys sponsored by central government agencies had the highest rates and those by universities the lowest. Among studies that used probability sampling, the highest median response rates were for drop self-administered questionnaires followed by face-to-face and mail surveys.

As suggested in the case of "the 100 charismas of tourism", local communities can be improved if at least one ultra-altruistic person engages in cooperative behavior for the benefit of the community. This paper investigated determinants of such pro-social behavior toward a local community by "regional charismas." For the purpose, a questionnaire survey was conducted based on determinant factors of altruistic behavior proposed by previous research. The respondents were 1) "the 100 charisma of tourism" (<i>n</i> = 95), 2) "residents living in the same region as the charismas" (<i>n</i>= 400), and 3) residents living in other regions (<i>n</i> = 500). By comparing different groups, individual and regional factors of pro-social behavior by "charismas" were examined. The results suggested that Schwartz's "norm activating factor" and "perceived benefits" regarding pro-social behavior directly related to individual factors of charismas' behavior, and "sympathy" among residents directly related to regional factors.

In this article, we study the limiting distributions of sample quantiles from a finite population. We give a simple proof of the asymptotic normality of sample quantiles for simple random samples from a finite population by employing the method of Wretman (1978). Some Monte Carlo simulation results are also included.

The traditional quantification procedure (e.g., dual scaling, correspondence analysis) is extended in order to tap into information which is typically ignored. Noting that the traditional symmetric scaling yields a visual image of distorted data structure and recalling that the widely used practice of looking at data in reduced space may also miss capturing rare but key-information in total space, a method, called total information analysis (TIA), is proposed to subject not only within-set but also between-set relations in total space. Numerical examples are used to explain why TIA offers partial solutions to some theoretical problems inherent in the current practice of multidimensional quantification analysis.
