Geographic interfaces provide natural, scalable visualizations for many digital library collections, but the wide range of data in digital libraries presents some particular problems for identifying and disambiguating place names. We describe the toponym-disambiguation system in the Perseus digital library and evaluate its performance. Name categorization(More)
The Perseus Project has developed a hypermedia corpus of materials related to the ancient Greek world. The materials include a variety of texts and images, and tools for using these materials and navigating the sytem. Results from a three-year evaluation of Perseus use in a variety of college settings are described. The evaluation assessed both this(More)

While the treebanks themselves present important datasets for traditional research in philology and linguistics, the layers of structured knowledge they contain (including disambiguated lemma, morphological, and syntactic(More)

In a typical digital library user interface, a user can either get an overview for context or(More)
