我正在尝试学习如何创建和训练用于抽取关系的语料库。我了解到我需要conll格式的语料库。但是，我不知道该如何训练语料库。
这是我必须以conll格式打印示例文本的一些代码。我不确定如何用适当的更改来修改此文件，然后进行培训。

String text = "The modern definition of artificial intelligence (or AI) is \"the study and design of intelligent agents\" where an intelligent agent is a system that perceives its environment and takes actions which maximizes its chances of success. " +
"John McCarthy, who coined the term in 1956, defines it as \"the science and engineering of making intelligent machines. " +
"Other names for the field have been proposed, such as computational intelligence, synthetic intelligence or computational rationality. " +
"The term artificial intelligence is also used to describe a property of machines or programs: the intelligence that the system demonstrates. " +
"AI research uses tools and insights from many fields, including computer science, psychology, philosophy, neuroscience, cognitive science, linguistics, operations research, economics, control theory, probability, optimization and logic. " +
"AI research also overlaps with tasks such as robotics, control systems, scheduling, data mining, logistics, speech recognition, facial recognition and many others. " +
"Computational intelligence Computational intelligence involves iterative development or learning (e.g., parameter tuning in connectionist systems). " +
"Learning is based on empirical data and is associated with non-symbolic AI, scruffy AI and soft computing. " +
"Subjects in computational intelligence as defined by IEEE Computational Intelligence Society mainly include: Neural networks: trainable systems with very strong pattern recognition capabilities. " +
"Fuzzy systems: techniques for reasoning under uncertainty, have been widely used in modern industrial and consumer product control systems; capable of working with concepts such as 'hot', 'cold', 'warm' and 'boiling'. " +
"Evolutionary computation: applies biologically inspired concepts such as populations, mutation and survival of the fittest to generate increasingly better solutions to the problem. " +
"These methods most notably divide into evolutionary algorithms (e.g., genetic algorithms) and swarm intelligence (e.g., ant algorithms). " +
"With hybrid intelligent systems, attempts are made to combine these two groups. " +
"Expert inference rules can be generated through neural network or production rules from statistical learning such as in ACT-R or CLARION. " +
"It is thought that the human brain uses multiple techniques to both formulate and cross-check results. " +
"Thus, systems integration is seen as promising and perhaps necessary for true AI, especially the integration of symbolic and connectionist models. ";
