实体ID的生成

[waltbai]

我通过 http://iesl.cs.umass.edu/riedel/ecml/ 直接解析出的实体ID都是以/guid/开头，而NRE中处理出的实体id是以m.xxx开头，请问这两个id的对应关系是怎么得到的？

你好
你是怎么从 那个网址解析数据的，我用 java 解析 protocol 数据，下面是我的代码

package cc.refectorie.proj.relation.protobuf;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;

import cc.refectorie.proj.relation.protobuf.DocumentProtos.Relation;

public class Main {
public static void main(String[] args) throws IOException {
//File file = new File("/home/wup/re_data/heldout_relations/trainPositive.pb");
FileInputStream fileInputStream = new FileInputStream("heldout_relations/testNegative.pb");
Relation relation=DocumentProtos.Relation.parseFrom(fileInputStream);
System.out.println(relation.getDestGuid());
}
}
但是编译运行后，回报这种错误
Exception in thread "main" com.google.protobuf.InvalidProtocolBufferException: Protocol message end-group tag did not match expected tag.

而且当我读取trainPositive.pb 时，报的错误还不一样。

你遇到过这种问题吗？
谢谢

Entity和Relation要通过parseDelimitedFrom方法解析
