SETUP INSTRUCTIONS for SINGLE USER LexDB

[see lkb/lexdb/README.single-user]

$ export MyLexDB=erg
$ createdb $MyLexDB

[NOW edit SQL script file 'su-init.sql' to specify the LexDB fields]

$ psql $MyLexDB
=> \i su-init.sql

[now load the field mappings...]

=> \copy dfn from lexdb.dfn
=> \q

[NOW load your grammar, as normal, in the LKB] [then open a connection to the empty LexDB...]

LKB(): (initialize-lexdb :type :single-user :dbname "MYLEXDB")

[and export you lexicon to dump files for the database...]

LKB(): (export-lexicon)

[import the dump file into the database...] [NOTE: encoding of lexicon/dump files must be UTF-8]

$ psql $MyLexDB
=> \copy lex from /home/bmw20/tmp/LinGO.rev

LKB->Set Options->*LEXDB-PARAMS* = ((:dbname "MYLEXDB") (:type :single-user))

[NOW reload grammar in LKB, and you should see a messages similar to the following:

...
(LexDB) connected to LexDB erg2@localhost:5432 as database user bmw20
(LexDB) total 'lex' entries available: 23055
...

]

[now we initialize the table of orthography keys...]

LKB(): (new-lex-key-table *lexicon*)

[and the database SEMI...]

LKB(): (new-semi *lexicon*)

THAT'S IT

Description:

• - lexicon entries should be made available in 'lex' (which can be a table or a view) - the mapping from database fields into AVM path-values in specified in 'dfn' - a table 'lex_key' is generated by '(new-lex-key-table *lexicon*)' and is used for lexicon lookup - a number of tables (and a view) 'semi_*' are generated by '(new-semi *lexicon*)' and store the database object SEMI - you are responsible for ensuring that there exists an appropriate index on the 'name' field of 'lex' (or things will run slow...) - you are free to define 'lex' as a view (eg. you could store a large number of lexicon entries in another table 'all_entries', create a table 'active'to specify which entry 'name's you want in view, then define 'lex' as:
  • CREATE VIEW lex AS active JOIN all_entries USING name;
