This paper presents a new parsing method using statistical information extracted from corpus, especially for Korean. The structural ambiguities are occurred in deciding the dependency relation between words in Korean. While guring out the correct dependency, the lexical associations play an important role in resolving the ambiguities. Our parser uses statistical cooccurrence data to compute the...

To investigate the mortality probability, life expectancy of coal workers' pneumoconiosis (CWP), and related factors of life expectancy, a total of 495 patients with CWP were diagnosed and reported from 1963 to 2014 in a state-owned mine in the east of China. The life table method, log rank method, and Cox regression model were used for survival analysis. 95 out of 495 CWP died during this peri...

A method is presented for estimating age-specific mortality based on minimal information: a model life table and an estimate of longevity. This approach uses expected patterns of mammalian survivorship to define a general model of agespecific mortality rates. One such model life table is based on data for northern fur seals (Callorhinus ursinu.r) using Siler’s ( 1979) 5-parameter competing risk...

This paper provides a unified setting for factor models applied to panels of qualitative observations. This setting includes as special cases the single risk factor model and its multiple factor extensions used in credit risk analysis, the stochastic migration models used for rating dynamics, and the factor models for prospective mortality tables. We consider the behavior of these models when t...

Understanding the variability of survival probabilities, both between and within cohorts, is important in order to understand life-cycle decisions under uncertainty. In this paper we analyze the subjective probabilities of survival to specific target ages provided by respondents to the Survey of Health, Ageing and Retirement in Europe (SHARE). To evaluate how these probabilities compare with ob...
