This repository provided a home for orphaned data previously found on http://nlp.perseus.tufts.edu/lexicon/ (also http://static.perseus.tufts.edu/lexicon/)

Note that active management of this phase of the project ceased in 2011. A new phase was started at: http://www.dynamiclexicon.com

General Information
The Dynamic Lexicon is an NEH-funded project to automatically create bilingual dictionaries (Greek/English and Latin/English) using parallel texts - source texts in Greek or Latin aligned with their English translations - along with the syntactic data encoded in treebanks. From these raw materials, we can construct a lexical entry that illustrates how a word is used not simply in all of Greek or Latin literature, but in any subset of that collection (e.g., Greek drama or the works of Cicero).

Data The published form of the Dynamic Lexicon includes automatically generated lexical entries along with the underlying intermediate analysis used to generate them (including word-level alignments between source texts and their translations, and automatic morphological tagging and syntactic analysis for the Greek and Latin originals). All data is licensed under a Creative Commons Attribution-Sharealike license.
