We present an overview of the Index Thomisticus Treebank project (IT-TB). The IT-TB consists of around 60,000 tokens from the Index Thomisticus by Roberto Busa SJ, an 11-million-token Latin corpus of the texts by Thomas Aquinas. We briefly describe the annotation guidelines, shared with the Latin Dependency Treebank (LDT). The application of data-driven(More)
In this paper, we provide a quantitative analysis of non-projective constructions attested in the Ancient Greek Dependency Treebank (AGDT). We consider the different types of formal constraints and metrics that have become standardized in the literature on non-projectivity (planarity, well-nestedness, gap-degree, edge-degree). We also discuss some of the(More)
The creation of language resources for less-resourced languages like the historical ones benefits from the exploitation of language-independent tools and methods developed over the years by many projects for modern languages. Along these lines, a number of treebanks for historical languages started recently to arise, including treebanks for Latin. Among the(More)
The paper describes the treatment of some specific syntactic constructions in two treebanks of Latin according to a common set of annotation guidelines. Both projects work within the theoretical framework of Dependency Grammar, which has been demonstrated to be an especially appropriate framework for the representation of languages with a moderately free(More)
We present a valency lexicon for Latin verbs extracted from the Index Thomisticus Tree-bank, a syntactically annotated corpus of Medieval Latin texts by Thomas Aquinas. In our corpus-based approach, the lexicon reflects the empirical evidence of the source data. Verbal arguments are induced directly from annotated data. The lexicon contains 432 Latin verbs(More)
Lemlat is a morphological analyser for Latin, which shows a remarkably wide coverage of the Latin lexicon. However, the performance of the tool is limited by the absence of proper names in its lexical basis. In this paper we present the extension of Lemlat with a large Onomasticon for Latin. First, we describe and motivate the automatic and manual(More)
Assuming that collaboration between theoretical and computational linguistics is essential in projects aimed at developing language resources like annotated corpora, this paper presents the first steps of the semantic annotation of the Index Thomisticus Treebank, a dependency-based treebank of Medieval Latin. The semantic layer of annotation of the treebank(More)
Although lexicography of Latin has a long tradition dating back to ancient grammarians, and almost all Latin grammars devote to wordformation at least one part of the section(s) concerning morphology, none of the today available lexical resources and NLP tools of Latin feature a wordformation-based organization of the Latin lexicon. In this paper, we(More)
We describe here a collaboration between two separate treebank projects annotating data for the same language (Latin). By working together to create a common standard for the annotation of Latin syntax and sharing our annotated data as it is created, we are each able to rely on the resources and expertise of the other while also ensuring that our data will(More)
English. This paper presents the steps undertaken for building a word formation lexicon for Latin. The types of word formation rules are discussed and the semi-automatic procedure to pair their input and output lexical items is evaluated. An on-line graphical query system to access the lexicon is described as well. Italiano. Questo articolo presenta le(More)
