Session outline

This sessoion will give an introduction to the use of treebanked/morphosyntactically annotated texts, following on from the introduction to treebanking give two weeks ago. We will begin with an overview of query and other research applications for treebanked text. We will then give a demonstration of the use of treebanks to train machine-learning algorithms to automatically add morphosyntactic annotations to Greek and Latin text. We will then show a case study involving querying treebanked texts using the Iliados tool. Finally, an exercise involving the correction of automated treebanks will be demonstrated.

Exercise

1. We know that in Ancient Greek, neuter plural subjects trigger either plural or singular agreement with the verb. This is supposed to be a relic of an old Indo-European collective number. How frequently does this happen in Homer? And in Aeschylus? Which agreement pattern is more frequent? Try to use the Iliados web app that was shown in class to answer these questions. Remember to:
   • formulate the problem as clearly as possible
   • define the features of the TB tokens that you want to consider (number, gender, syntactic relation...)
   • find out how to build a query that selects these features using the syntax of the query language implemented by Iliados
