This regression problem is dicult for several reasons: large number of examples, large number variables (most of which are discrete and multi-valued), non-stationarity of the distribution, and a conditional distribution of the dependent variable which is very dierent from those usually encountered in typical applications of machine learning and function approximation.

这个回归问题是，邸邪教组织有多少个原因：大量的例子，大批变量（其中大部分是离散和多值），非平稳性的分布，以及有条件的分布因变量，这是非常邸erent从这些一般遇到的典型应用机器学习和函数逼近。

In this study, I created a tagging system based on conditional random field models for this task.

在本研究中使用了条件随机场做为机器学习的模型演算法，透过此一模型去解决此一辨识生物专有名词的问题。

They are proposed firstly by Cortes and Vapnik in 1995 and have become an important research direction in the field of machine learning.

它是Cortes和Vapnik于1995年首先提出来的，已成为近年来机器学习研究的一项重大成果。

Aiming at solving the problems of heterogeneity among ontologies in semantic Web services, and taking into account the fact that the efficiency of most ontology mapping system is not high and the results of ontology mapping is not accurate enough, this paper proposed efficient ontology mapping method and system framework for semantic Web services, the method adopted machine learning techniques to enhance the degree of automation of ontology mapping, used comprehensive evaluation technology to amend the results of ontology mapping, so as to improved the accuracy of ontology mapping.

芦明， 李冠宇，史一民大连海事大学信息科学技术学院，辽宁大连 116026）本体的异构性阻碍了语义网服务的互操作。从解决语义网服务中本体的异构问题出发，同时考虑到目前的本体映射系统大多效率不高、映射结果不够准确的问题，提出了一种适用于语义网服务的本体映射方法及系统框架。该方法利用机器学习技术来提高本体映射的自动化程度，利用综合评判技术修正映射结果，以提高本体映射的准确率。
