ToolGood.Words

一款高性能非法词、敏感词检测库。还支持繁体简体互换、获取拼音首字母、获取拼音字母、拼音模糊搜索等功能

string s = "中国|国人|zg人";
string test = "我是中国人";

StringSearch iwords = new StringSearch();
iwords.SetKeywords(s.Split('|'));

var b = iwords.ContainsAny(test);
Assert.AreEqual(true, b);

var f = iwords.FindFirst(test);
Assert.AreEqual("中国", f);

var all = iwords.FindAll(test);
Assert.AreEqual("中国", all[0]);
Assert.AreEqual("国人", all[1]);
Assert.AreEqual(2, all.Count);

var str = iwords.Replace(test, '*');
Assert.AreEqual("我是***", str);

machinelearning

微软开源的 C# 机器学习框架。支持的机器学习类任务：分类、回归、聚类等，教程和视频。示例代码：

var dataPath = "sentiment.csv";
var mlContext = new MLContext();
var loader = mlContext.Data.CreateTextLoader(new[]
    {
        new TextLoader.Column("SentimentText", DataKind.String, 1),
        new TextLoader.Column("Label", DataKind.Boolean, 0),
    },
    hasHeader: true,
    separatorChar: ',');
var data = loader.Load(dataPath);
var learningPipeline = mlContext.Transforms.Text.FeaturizeText("Features", "SentimentText")
        .Append(mlContext.BinaryClassification.Trainers.FastTree());
var model = learningPipeline.Fit(data);

var predictionEngine = mlContext.Model.CreatePredictionEngine<SentimentData, SentimentPrediction>(model);
var prediction = predictionEngine.Predict(new SentimentData
{
    SentimentText = "Today is a great day!"
});
Console.WriteLine("prediction: " + prediction.Prediction);
