您按每行提取信息并识别其中一些,例如第 6-8 行被识别,您也可以将第 9 行定义为电子邮件。
所以你对第 1-5 行的唯一疑问。
您不能 100% 确定线路是否适合或不适合任何正则表达式,因为没有“协议”应该如何在卡上打印地址,因此您可以假设
- 最可能的地址应该在第 2 行以上,因为在大多数情况下,第 1 行会有公司名称。
- 地址的一部分应该包含预定义的值,例如
- 大道
- 英石。
- 街道
- [XX](状态定义)
- Zip - 邮政编码的正则表达式非常简单
- 其他关键词
- 最有可能的地址将以邮政编码开头。
因此,如果您将所有这些结合到一个方法中,您将获得一种算法,该算法可以预测是否存在可能的地址。
根据上面的假设,第 4 行和第 5 行地址更可能是因为 - 第 4 行从一个看起来像邮政编码的数字开始, - 第 5 行包含有点像状态

复杂的解决方案可能如下所示:
public static float checkLineForAddress(List<String> testdata) {
boolean containsZip = false;
boolean containsState = false;
boolean containsAddressKeyword = false;
boolean containsWord = false;
boolean containsCapitalizedWord = false;
boolean containsNumber = false;
boolean containsBuildingNum = false;
for (String item : testdata) {
Set<Map.Entry<String, String>> entries = zipRegexps.entrySet();
for (Map.Entry<String, String> entry : entries) {
containsZip = containsZip || item.matches(entry.getValue());
if (containsZip) break;
}
containsState = containsState || item.matches("[A-Z]{2}");
containsBuildingNum = containsBuildingNum || item.contains("/");
containsWord = containsWord || item.matches("[A-Za-z]+");
containsCapitalizedWord = containsCapitalizedWord || item.matches("[A-Z]+[a-z]+");
for (String addressKeyword : addressKeywords) {
containsAddressKeyword = containsAddressKeyword || item.replace(".", "").equalsIgnoreCase(addressKeyword);
}
containsNumber = containsNumber || item.matches("[0-9]+");
}
float addressProbability = 0;
if (containsZip && containsCapitalizedWord && (containsState || containsAddressKeyword)) return 1f;
if (containsZip && containsWord) addressProbability = 0.5f;
if (containsCapitalizedWord) addressProbability += 0.1f;
if (containsAddressKeyword) addressProbability += 0.2f;
if (containsNumber) addressProbability += 0.05f;
if (containsBuildingNum) addressProbability += 0.05f;
if (testdata.size() > 1) addressProbability += 0.05f;
if (testdata.size() > 2) addressProbability += 0.05f;
return addressProbability;
}
我从这里获取了一个邮政编码列表:什么是最终的邮政编码和邮政编码?, 变量的初始化方法:

测试数据是
List<String> testdata = new ArrayList<>();
testdata.add("1380");
testdata.add("Rio");
testdata.add("Rancho");
testdata.add("Blvd");
testdata.add("SE363");
Log.e("!@#", String.valueOf(checkLineForAddress(testdata)));
testdata = new ArrayList<>();
testdata.add("Rio");
testdata.add("Rancho");
testdata.add("NM");
testdata.add("87124");
Log.e("!@#", String.valueOf(checkLineForAddress(testdata)));
testdata = new ArrayList<>();
testdata.add("Wayne");
testdata.add("Stansfield");
testdata.add("i");
testdata.add("CLCS");
Log.e("!@#", String.valueOf(checkLineForAddress(testdata)));
testdata = new ArrayList<>();
testdata.add("James");
testdata.add("Gordon");
testdata.add("Smith");
Log.e("!@#", String.valueOf(checkLineForAddress(testdata)));
testdata = new ArrayList<>();
testdata.add("5052");

testdata = new ArrayList<>();
testdata.add("Creative");
testdata.add("Director");
Log.e("!@#", String.valueOf(checkLineForAddress(testdata)));
并输出
E/!@#: 1.0
E/!@#: 1.0
E/!@#: 0.70000005
E/!@#: 0.2
E/!@#: 0.15
E/!@#: 0.15
如您所见,第 3 行是一个概率为 70% 的地址,因为理论上CLCS
可能是百慕大邮政编码。
您可以根据您的测试数据修改可能性。
