Detecting and Browsing Events in Unstructured Text, 2002

 Item
Call Number: PB.001.006.00002
Scope and Contents: Previews and overviews of large, heterogeneous information resources help users comprehend the scope of collections and focus on particular subsets of interest. For narrative documents, questions of \what happened? where? and when?" are natural points of entry. Building on our earlier work at the Perseus Project with detecting terms, place names, and dates, we have exploited co-occurrences of dates and place names to detect and describe likely events in document collections. We compare...

Detecting Events with Date and Place Information in Unstructured Text, 2002

 Item
Call Number: PB.001.006.00001
Scope and Contents: Digital libraries of historical documents provide a wealth of information about past events, often in unstructured form. Once dates and place names are identified and disambiguated, using methods that can differ by genre, we examine collocations to detect events. Collocations can be ranked by several measures, which vary in effectiveness according to type of events, but the log-likelihood measure offers a reasonable balance between frequently and infrequently mentioned events and between larger...

Disambiguating Geographic Names in a Historical Digital Library, 2001

 Item
Call Number: PB.001.006.00003
Scope and Contents: 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 varies significantly among different types of documents, but toponym disambiguation performs at a high level of precision and recall with a...

Document Quality Indicators and Corpus Editions, 2001

 Item
Call Number: PB.001.001.00013
Scope and Contents: Corpus editions can only be useful to scholars when users know what to expect of the texts. We argue for text quality indicators, both general and domain-specific.

Drudgery and Deep Thought: Designing Digital Libraries for the Humanities, 2001

 Item
Call Number: PB.001.001.00011
Scope and Contents: This is an expanded version of an article that appeared in the Communications of the ACM, May 2001 section on digital libraries. The published version is more informal. In this article, we describe the challenges of creating digital libraries for the humanities, based on our experience with a series of heterogeneous projects ranging from Ancient Greece to 19th-century London.
