Lexicon Interaction with CVS

• Before updating the lexicon file lex/Jacy.rev

• * do your normal checks

• ** (lkb::batch-check-lexicon)

• ** dump to tdl and flop

• * optionally back up your existing lexicon

• * dump the lexical database

   psql jacy
   jacy=# \copy lex to japanese/lex/Jacy.rev 
  

• Merge using normal CVS update

• * Check things again

• ** load the revisions, reindex, run the grammar etc

• ** dump the tdl

• Update the Jacy.rev and tdl lexicon

Set Up

Set up the database as described in the [wiki:LkbLexDbSingleUser Single User] page, then load the lexicon from CVS.

• Connect to the database (normally called jacy)

   psql jacy 
  

• Create the Databases

   jacy=# \i japanese/lex/su-init.sql 
  

  • Load the definitions

   jacy=# \copy dfn from  japanese/lex/lexdb.dfn 
  

  • Load the lexical entries

   jacy=# \\copy lex from japanese/lex/Jacy.rev 
  

• Load Jacy and set up the *lexdb-params* through the LKB Options::Set Options... menu

   ((:DBNAME "jacy") (:TYPE :SINGLE-USER)) 
  

• Index for parsing and generation

   (lkb::new-lex-key-table lkb::*lexicon*)
   (lkb::new-semi lkb::*lexicon*)
  

ToDo

• currently we can't delete entries, so we mark anything we want to delete with the string delete in the comment field.
