INSTRUCTIONS TO USE THE PROGRAMS

================================

To uncompress the program:

tar -xvf irs3.tar

There will be some files in the main directory and two sub-directories named "data" and "indexdb" respectively.

There are 5 sample documents in the directory of "data".

To compile the program:

  1. Go to the your main directory where the programs are stored and run:

make - to make irmain

and make index to make irindex

To execute the program:

  1. Go to sub-directory "indexdb".

Modify the first line of "filelist.dat" to include the full path to the directory where your list of data files are stored

  1. Go to sub-directory "indexdb"

run ../irindex to create the indices: this will take a while when computing weights for vector space model.

run ../irmain to try out different queries.

For Linux, use the version under irslinux.tar:

It is a little bit different from the Unix version. It works on Linux Mandrake which uses gcc-2.95.2 and g++-2.95.2.

For other linux versions, the location of "ndbm.h" may change. In Mandrake we use "#include<db1/ndbm.h>" (in "filesys1.h"). You may probably (maybe, not sure) need to change two lines in Makefile for generating irmain and irindex. In Solaris, the ndbm files are stored as .dir and .pag. But in Mandrake, the files are stored only as .db. After changing the path of including the ndbm.h, the compiling procedure should be similar as mentioned above.
