- The Linguistic DataBase (LDB) is a database program created by the TOSCA
- corpus linguistics group at Nijmegen University for the storage and
- exploration of syntactically analysed texts. It features a tree viewer
- and an extensive query language.
-
- The LDB program, together with a 130,000 word analysed corpus of modern English
- (the Nijmegen corpus), is available free of charge to academic institutions and
- for Hfl. 5000,- to others.
-
- A tutorial and reference manual for the LDB can be found in the book:
- Linguistic Exploitation of Syntactic Databases
- Hans van Halteren and Theo van den Heuvel
- Rodopi, Amsterdam (1990)

- The demonstration version of the LDB accompanying this information file
- will run on any MSDOS machine with a drive C: with about 650K of free space.
- No graphics card is required. The demo program is fully operational except for
- the following limitations:
- - the program will run only from drive C:
- - in all analysis tree databases only the first 200 trees are accessible
-
- The files LDBDEMOC.INF and LDBDEMOC.EXE can be copied and distributed
- freely, providing they are kept together. Furthermore, no money may be
- charged for distribution, except for the cost of distribution medium and
- postage.
-
- ==============================================================================
-
- To move the demo version to your machine:
- A) If you have received the distribution diskette, obtained the software
- through ftp (binary mode) or executed step B) below you have a program
- named LDBDEMOC.EXE. Move to the directory where this file is stored and
- type (while drive C: is available):
- ldbdemoc -d c:\
- In case this does not yield the files described below, but instead
- the files DONOTRUN.EXE and RUNTHIS.BAT, you started with a special,
- safeguarded version of LDBDEMOC.EXE. This version is meant to prevent
- people who don't have LDBDEMOC.INF (or haven't read it) from accidentally
- removing existing files by executing LDBDEMOC.EXE without parameters.
- As you may already have guessed, you must now type
- c:\runthis
- B) If you have obtained the software through LISTSERV you have the file
- named LDBDEMOC.UUE. You must use UUDECODE to translate this:
- uudecode ldbdemoc.uue
- Now continue as described under A) above.
-
- The result should be a directory C:\LDB with the following contents:
- LDB
- DAT
- ADEM01.ANA
- ADEM01.COR
- BW104.ANA
- BW104.COR
- DEMO
- ADEMLDB.DAT
- LADEMLDB.CMD
- LDBDEMO.BAT
- SADEMLDB.CMD
- INFO
- ANALYSES.INF
- LDBDEMOC.INF
- PROG
- ANSI.SYS
- BATCH.DEF
- DEFAULT.KWD
- DEMO.DEF
- INTER.DEF
- LDB.BAT
- LDBCREAT.BAT
- LDBINCL.BAT
- LDBPDEMO.EXE
- LDBPRCIN.EXE
- LDBPRCLD.EXE
- LDBPRCPR.EXE
- LDBPREP.BAT
- LDBPRGCR.EXE
- WORK
- LDB.DAT
-
- The demo is operational if the system has been booted while:
- - CONFIG.SYS contains the line
- DEVICE=ANSI.SYS
- - ANSI.SYS is present in the root directory of the boot disk
-
- To run the demo (did you check your CONFIG.SYS?):
- c:
- cd \ldb\demo
- ldbdemo
-
- ==============================================================================
-
- Once you are familiar with the LDB you can also use it outside the demo
- environment. For this, C:\LDB\PROG must be part of the search path. This can
- be effected by placing the line
- PATH=C:\LDB\PROG
- in the file AUTOEXEC.BAT in the root directory of the boot disk. If there is
- already a PATH command in AUTOEXEC.BAT append
- ;C:\LDB\PROG
- to this line.
-
- To run the LDB:
- c:
- cd \ldb\work
- ldb
-
- When running the LDB in this fashion, your own work (such as exploration
- schemes you stored in the database) will not disappear after you leave
- the program. If you inadvertently delete the file LDB.DAT, you can create
- a new one by copying the file ADEMLDB.DAT in the directory DEMO. In this case,
- however, you do lose everything you may have stored yourself.
