c# - C# 中匹配不同格式句子的正则表达式

Question

文件格式

POS ID         PosScore NegScore    SynsetTerms                          Gloss
a   00001740    0.125   0           able#1"                              able to swim"; "she was able to program her computer";
a   00002098    0       0.75        unable#1                            "unable to get to town without a car"; 
a   00002312    0       0           dorsal#2 abaxial#1                  "the abaxial surface of a leaf is the underside or side facing away from the stem"
a   00002843    0       0           basiscopic#1                         facing or on the side toward the base
a   00002956    0       0.23        abducting#1 abducent#1               especially of muscles; drawing away from the midline of the body or from an adjacent part
a   00003131    0       0           adductive#1 adducting#1 adducent#1   especially of muscles; 

在此文件中，我想提取(ID、PosScore、NegScore 和 SynsetTerms) 字段。 (ID,PosScore,NegScore)字段数据提取很容易，我对这些字段的数据使用以下代码。

Regex expression = new Regex(@"(\t(\d+)|(\w+)\t)");

var results = expression.Matches(input);
foreach (Match match in results)
{

    Console.WriteLine(match);
}
Console.ReadLine();  

它给出了正确的结果，但是归档的SynsetTerms产生了一个问题，因为有些行有两个或更多单词，那么如何组织单词并对抗它PosScore和NegScore。

例如，第五行有两个单词 abducting#1 和 abducent#1 但两者的分数相同。

那么获取 Word 及其分数的行的正则表达式是什么，例如:

  Word                PosScore          NegScore 
  abducting#1         0                 0.23
  abducent#1          0                 0.23

非正则表达式、字符串分割版本可能更容易:

var data =
   lines.Split(new[] {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries)
        .Skip(1)
        .Select(line => line.Split('\t'))
        .SelectMany(parts => parts[4].Split().Select(word => new
            {
                ID = parts[1],
                Word = word,
                PosScore = decimal.Parse(parts[2]),
                NegScore = decimal.Parse(parts[3])
            }));
