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. at com.google.protobuf.InvalidProtocolBufferException.invalidEndTag(InvalidProtocolBufferException.java:110) at com.google.protobuf.CodedInputStream$StreamDecoder.checkLastTagWas(CodedInputStream.java:2128) at com.google.protobuf.AbstractParser.parsePartialFrom(AbstractParser.java:223) at com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:239) at com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:244) at com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:49) at com.google.protobuf.GeneratedMessageV3.parseWithIOException(GeneratedMessageV3.java:311) at cc.refectorie.proj.relation.protobuf.DocumentProtos$Relation.parseFrom(DocumentProtos.java:7693) at cc.refectorie.proj.relation.protobuf.Main.main(Main.java:13)

而且当我读取trainPositive.pb 时，报的错误还不一样。 Exception in thread "main" com.google.protobuf.InvalidProtocolBufferException$InvalidWireTypeException: Protocol message tag had invalid wire type. at com.google.protobuf.InvalidProtocolBufferException.invalidWireType(InvalidProtocolBufferException.java:115) at com.google.protobuf.UnknownFieldSet$Builder.mergeFieldFrom(UnknownFieldSet.java:551) at com.google.protobuf.GeneratedMessageV3.parseUnknownField(GeneratedMessageV3.java:293) at cc.refectorie.proj.relation.protobuf.DocumentProtos$Relation.(DocumentProtos.java:6200) at cc.refectorie.proj.relation.protobuf.DocumentProtos$Relation.(DocumentProtos.java:6132) at cc.refectorie.proj.relation.protobuf.DocumentProtos$Relation$1.parsePartialFrom(DocumentProtos.java:8482) at cc.refectorie.proj.relation.protobuf.DocumentProtos$Relation$1.parsePartialFrom(DocumentProtos.java:8476) at com.google.protobuf.AbstractParser.parsePartialFrom(AbstractParser.java:221) at com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:239) at com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:244) at com.google.protobuf.AbstractParser.parseFrom(AbstractParser.java:49) at com.google.protobuf.GeneratedMessageV3.parseWithIOException(GeneratedMessageV3.java:311) at cc.refectorie.proj.relation.protobuf.DocumentProtos$Relation.parseFrom(DocumentProtos.java:7693) at cc.refectorie.proj.relation.protobuf.Main.main(Main.java:13) 你遇到过这种问题吗？ 谢谢

Entity和Relation要通过parseDelimitedFrom方法解析
