  1. CHLT Integration

  2. Integration in two directions • Interoperability with indexing structures of Perseus Digital Library • Integration of parsers into indexing module of search and visualization tool

  3. Integration with Structure of Perseus Digital Library • Perseus text display system transforms XML and legacy SGML files tagged according to an arbitrary DTD and creates a consistent set of core data files that can be read by any application • Sentences • Chunks • Lemmatized • Inflected • Catalog of works (PTEXT DB) • Morphological Databases • Short Definitions

  4. File Locations • The surrogate files are written to a location that is associated with the unique ID assigned to the document in the PDL. • Each chunk or sentence also has a unique identifier • These two pieces of information can be used: • To generate URLs to access full text in DL • To generate human readable citations of the sentences according to scholarly conventions

  5. WP2 Integration: Word Profile Tool • Word Profile tool reads lemmatized files to acquire a complete list of words in IGL corpus • All frequency counts, display sentences, human readable citations, and links to full text are based on surrogate files generated by PDL.

  6. WP2 Integration: Multi-Lingual IR Tool • Author and language selection routines in MLIR tool is dynamically generated from PDL metadata catalog • Database of translation equivalents is created directly from SGML/XML and saved as a core data file that is available to other applications in the system • Translation Equivalence Program works with any TEI conformant dictionary. Dictionary selection screen updates dynamically. • Translated query is handed off to current PDL search engine and the visualization tool based on documented APIs

  7. WP4 Integration: Old Norse Text and Parser • Middleware translates Old Norse Parser output to format used by PDL • ISO Language tags in texts tell system to use Old Norse morphology and link to Old Norse lexicon • PDL short definition program automatically extracts information from Zoega

  8. WP4 & 6: Corpus Integration • TEI makes corpus integration easy • Old Norse texts and lexica and Neo-Latin texts are tagged according to TEI standards • Documentation of tagging conventions.

  9. Parser Integration with WP1 • Similar middleware can link LemLat to PDL • WP1 Visualization Tool also includes a parsing/stemming step • This program is designed generally to work with many systems, not simply those created by PDL • Source code for LemLat and Old Norse so that search/visualization tool can be used to search Old Norse and Latin texts that are not part of PDL

  10. Next Steps: • Implementation of parser integration with WP1 • Seamless integration of MLIR tool and production deployment • Improved documentation of tags required for OAI linking
