  • Infomap NLP Software: Not in development any more. The authors recommend to use SemanticVectors instead!!!
    • Uses Latent Semantic Analysis
    • The implementation is in C.
    • Infomap is intended to build `language models' and to perform information retrieval tasks on the such models
    • Simple input format
    • You might need gdbm libraries. I had troubles installing this libraries in my laptop. In the present moment it is not working.
    • The documentation includes installation instructions, algorithm description and implementation guide.

  • Before installing Infomap you would have to install gdbm libraries in your computer. This could be quite challenging. In the following I document the installation process I followed.
  1. As a first step, you should download the last version of gdbm.
  2. Untar the .gz file and go into the created directory.
  3. Try:

    This command should try to configure the program to your system specifications. It is highly likely that this process fails. The most likely reason is that a system library called libtool is not version compatible. To check your version of this program (in ubuntu):

    apt-cache policy libtool

    . I presuppose you have libtool installed in your computer. You probably have a newer version of libtool as the one presuppose by the gdbm package. The solution I found was to run:

    autoconf -f -oconfigure
  4. The last overwrote all the libtool-related files in the directory. Now you can run

    safely. If you obtain the following error -which actually is highly unlikely

    checking build system type... Invalid configuration `x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized

    you will need to deceive the program. Add before any command:
