    I have Java 1.4, WordNet 2.1 and JWNL 1.2 on my machine, and I wish to be able to use WordNet from inside a Java program to infer various lexical information about words. Typically, I will need to see if a word is a hyponym of person, for instance.

    My problem is that I am not getting started at all! I have made a correction in the file_properties.xml file so that the dictionary path leads to the dict folder of my WordNet installation:

    C:\Programfiler\WordNet\2.1\dict

    Still I get the below quoted error message when I try to run my short test file:

    Please help, anyone!

    • Hi,

      is it possible that there is a typo in your path?
      > C:\Programfiler\WordNet\2.1\dict
                              ^^^^

      What do you mean? Capital C? I have tried lower case c, it doesn't make any difference. I am sure that the path is correct, any other tips?

       
      • No, sorry. I was thinking of a typo in the word 'Programfiler' since this directory is often called 'Program Files'. However, your Windows installation probably uses your native language.

      Oh, I see. Well, I am sure that is correct. Can you think of any other reasons?
