LkbLexDbMultiUser

MULTI USER LexDB

• First, set up psql. This is discussed in LexDbPsqlInitialize.

• The next steps are to initialize a database, populate it with lexicon entries and finally to tell the LKB to use this when you load a grammar.

HOW TO initialise LexDB

You must create a new database to hold the LexDB. The LexDB-specific database structures must then be initialized. For the purpose of these instructions assume the LexDB will be called erg with LexDB config files ~/erg/lexdb.*; if you do not yet have a .fld and a .dfn file you must create these before proceeding (see LexDbFieldMappings); you also need a .rev file with which to populate the database.

• At shell prompt (M$ Windows users will need Cygwin):

 $ cd lkb/lexdb
 $ bash install-lexdb.sh erg ~/erg lexdb

(Note: The encoding for the lexical database will be set to UNICODE.)

• You can view the field mappings in the field dfn just to make sure:

user@localhost:~/lkb/lexdb$ psql erg
Welcome to psql 8.3.5, the PostgreSQL interactive terminal.

       \h for help with SQL commands

HOW TO create skelatal (empty) LexDB

As above, but use an empty .rev file. This can be created with a shell command such as the following:

echo '' > lexdb.rev
