<h4>labels</h4>

<div class="block">采用与CRF++兼容的模板格式，具体参见：<a>http://crfpp.googlecode.com/svn/trunk/doc/index.html#usage</a> <br/>

<h4>funWeight</h4>
<pre>double[] funWeight</pre>
<div class="block">CRF特征函数的权值数组 <br/>
 假定labels的大小为K，则每个状态特征可以生成K个特征函数，对于第i个状态特征，
 其对应的K个状态特征函数的权重为：funWeight[K*i,K*i+1,..., K*i + K -1] <br/>
 同理，对于每个转移特征，则可以生成K * K个转移特征函数，对于第j个转移特征，
 其对应的K * K个转移特征函数的权重为：bFunWeight[j*K*K, j*K*K, ... , j*K*K + K*K -1]<br/>
 状态特征为：Unigram，标记为'u'<br/>
 转移特征为：Bigram，标记为'b'<br/></div>

<h4>uFeatureAddr</h4>
<pre>java.util.HashMap&lt;K,V&gt; uFeatureAddr</pre>
<div class="block">每个状态特征在funWeight中的首地址映射，如：第i个特征为：'U10:%x[-2,1]'，则其对应K * i</div>
