+# Norma Syllabarum Graecarum - A Benchmark for grc Syllabification and Vowel Length Annotation
+
+We introduce *Norma* as a common benchmark for the evaluation and comparison of NLP tools concerning markup of two tasks for Ancient Greek (grc): (1) **vowel length** of dichronic vowels (alpha, iota, ypsilon) in open syllables (where they impact syllable weight) and (2) **syllabification**, both boundaries and weight. This means that the benchmark also indirectly tests handling of sandhi phenomena and, for verse, metre.
+
+The benchmark includes 1228 lines of text by each of the below 14 authors, spanning many periods and genres of both verse and prose:
+
+- Alcman (*Louvre Partheneion* 36-49, mix of aeolic, trochaic and dactylic cola, NB: contains digamma, ϝ)
+- Bacchylides (*Epinikion 5*, anapaesto-iambic and dactylo-troachaic)
+- Aeschylus (*Supplices* 1-10, anapaests)
+- Sophocles (*Oedipus Tyrannus* 1-20, iambic trimeter)
+- Euripides (*Bacchae* 1-20, iambic trimeter)
+- Thucydides (*Thucydidis historiae* 1.1.1.1-1.2.2.1, prose)
+- Aristophanes (*Acharnenses* 1-16, iambic trimeter, and 299 lines from responding lyric songs)
+- Plato (*Cratylus* 383-384a5, prose)
+- Dioscorides (*Anthologia Graeca* 5.55, elegiac distichs)
+- Plutarch (*Stoicos absurdiora poetis dicere* 1057.C1-F1, prose)
+- Epictetus (*Enchiridion* 1.1.1-1.5.1, prose)
+- Origenes (*Contra Celsum* 1.1-1.20, prose)
+- Nonnus (*Dionysiaca* 1-20, dactylic hexameter)
+- Quintus (*Posthomerica* 1-20, dactylic hexameter)
+
+The repository also provides a validation set, [`data/validation.jsonl`](data/validation.jsonl), containing 764 lines from Aristophanes' lyric poetry for the macronization task.
+
+## Markup Format
+
+For the syllabification task the markup is:
+
+- square brackets [] enclose heavy syllables
+- curly brackets {} enclose light syllables
+
+and for the macronization task the markup is:
+
+- carets ^ follow short ambiguous vowels (α, ι, υ)
+- underscores _ follow long ambiguous vowels (α, ι, υ).
+
+In prose, for ease of comparison we consider the sentence to be the equivalent of the verse line, with the consequence that the final syllable of a sentence will be considered heavy if it ends with a consonant, even though the following sentence begins with a vowel; i.e. a prose *brevis in longo*.
+
+With regard to vowel length, the benchmark is designed to test performance of open (light) syllables only. This means that *all* open syllables with ambiguous vowels (α, ι, υ) have them marked with carets or underscores, while this is only *sporadically* true for closed syllables (and in such cases mostly before mute-liquid clusters).
+
+We also have an example of a word that avoids the normal rules of syllabification:
+
+- ...[ῇ]**{σι^ }{Σκα^}**[μάν][δρου,] (*Posthomerica*, 10)
