Описание:Text classification (TC) is the task of automatically categorizing text into pre-set categories by analyzing their contents. First, the development of a new TC model based on hidden Markov model (HMM) proposed as a new framework for TC task. Few, however, have applied HMM to TC. Second, the application of the Library of Congress Classification (LCC) as a classification scheme for automatically organizing digital resources. Two primary objectives are: The proposed model is compared to a Naive Bayesian model, which has been extensively used in TC applications. A general prototype for an HMM-based TC model is proposed and implemented, so as to classify a collection of dissertation abstracts from the ProQuest Digital Dissertations database into LCC. HMM has been applied to a wide range of applications in text processing such as text segmentation and event tracking, information retrieval, and information extraction. Lastly, current TC challenges and issues are discussed. In this monograph, a framework of a new TC model based on hidden Markov model is proposed, and its implementation is demonstrated in an application of library and information science.

The Teachings of Don Juan: A Yaqui Way of Knowledge

I divided the data into areas of related concepts and procedures and arranged the areas hierarchically according to subjective importance — that is, in terms of the impact that each of them had had on me. In that way I arrived at the following classification: uses of the hallucinogenic plants; procedures and formulas used in sorcery; acquisition and manipulation of power objects; uses of the medicinal plants; songs and legends. Reflecting upon the phenomena I had experienced, I realized that my attempt at classification had produced nothing more than an inventory of categories; any attempt to refine my scheme would therefore yield only a more complex inventory. That was not what I wanted. During the months following my withdrawal from the apprenticeship, I needed to understand what I had experienced, and what I had experienced was the teaching of a coherent system of beliefs by means of a pragmatic and experimental method. It had been evident to me from the very first session in which I had participated that Don Juan's teachings possessed an internal cohesion ...»

The Use of Copulas in Asset Allocation. When and How a Copula Model can be Useful?
I try to achieve this by developing an analysis on the composition of the optimal portfolio and on the cost of the Markowitz allocation compared to an allocation that uses models with copulas (Normal, Student-t, Clayton, Gumbel, Frank, mix copulas and Canonical Vine copulas) in portfolios composed by 2 or more assets, analyzing various combinations of indices to test whether the use of copulas improves the investor' s utility and revenue. Moreover I build models that considers return moments and co-moments till the fourth power in order to understand whether they can approximate the use of copulas to obtain optimal weights. The analysis should be interesting to Investment Fund Asset Managers, but also to academic researchers. I evaluate the problems caused by the use of the mean-variance criterion, conceived by Markowitz, that addresses the allocation of financial portfolios. Many authors have suggested that the mean-variance criterion can not correctly proxy the expected utility with non-Normal returns. Thus, a strategy is needed that can enable us to understand whether the loss of optimality due to the mean-variance criterion is significant or negligible.
