示例1: Split

        public void Split(string name, double minAccuracy, Sentence[] train, Sentence[] test)
        {
            Assert.Greater(train.Length, 0);
            Assert.Greater(test.Length, 0);
            Assert.Greater(train.Length, test.Length);

            LuMiiTagger tagger = new LuMiiTagger();

            Stopwatch trainTimer = new Stopwatch();
            trainTimer.Start();
            tagger.Train(train);
            trainTimer.Stop();

            Stopwatch tagTimer = new Stopwatch();
            tagTimer.Start();
            tagger.Tag(test);
            tagTimer.Stop();

            Token[] tokens = test.SelectMany(t => t).ToArray();
            double accuracyTag = (double)tokens.Count(t => t.IsTagCorrect) / tokens.Count();
            double accuracyMsd = (double)tokens.Count(t => t.IsMsdCorrect) / tokens.Count();
            double accuracyMsdLemma = (double)tokens.Count(t => t.IsMsdCorrect && t.IsLemmaCorrect) / tokens.Count();
            double accuracyLemma = (double)tokens.Count(t => t.IsLemmaCorrect) / tokens.Count();

            Token[] lemmaIncorrect = tokens.Where(t => t.IsMsdCorrect && !t.IsLemmaCorrect).ToArray();

            Debug.WriteLine("Split validation for " + name);
            Debug.WriteLine("Train: {0} sentences, {1} tokens", train.Length, train.SelectMany(t => t).Count());
            Debug.WriteLine("Test: {0} sentences, {1} tokens", test.Length, test.SelectMany(t => t).Count());
            Debug.WriteLine("Accuracy tag: {0:0.00}%", accuracyTag * 100);
            Debug.WriteLine("Accuracy msd: {0:0.00}%", accuracyMsd * 100);
            Debug.WriteLine("Accuracy msd + lemma: {0:0.00}%", accuracyMsdLemma * 100);
            Debug.WriteLine("Accuracy lemma: {0:0.00}%", accuracyLemma * 100);
            Debug.WriteLine("Train duration: {0} or {1:0} ms", trainTimer.Elapsed, trainTimer.ElapsedMilliseconds);
            Debug.WriteLine("Tag duration: {0} or {1:0} ms", tagTimer.Elapsed, tagTimer.ElapsedMilliseconds);
            Debug.WriteLine("Tag speed: {0:0.00} tokens/s", tokens.Length / tagTimer.Elapsed.TotalSeconds);

            Assert.Greater(accuracyMsdLemma, minAccuracy);
            Assert.Less(accuracyMsdLemma, 0.97);
        }
