Hi everyone.
Is there any open source/free software available that gives you semantically related keywords for a given word. for example the word dog: it should give the keywords like: animal, mammal, ... or for the word France it should give you keywords like: country, Europe ... . basically a set of keywords related to the given word.
or if there is not, has anybody an idea of how this could be implemented and how complex this would be.
best regards
Yes. A company named Saplo in Sweden specialize in this. I beleive you can use their API for this and if you ask nicely you might be able to use it for free (if it's not for commercial purposes of course).
Hi Andrew,
Saplo has this kind of support. Though it is not publicly accessible in Saplo API yet but now we will take your use case in consideration.

Yes. What you are looking for is something similar to vector space model for searching and it is the best efficient way of doing. There are some open source libraries available for latent semantic indexing / searching ( special case of vector space model). Apache Lucene is one of the most pupular one. Or something from google code.
Wordnet might be what you need. Wordnet groups English words in sets of synonyms and provides general definitions, and records the various semantic relations between these groups.
There are tons of projects out there using Wordnet, here you have a list: http://wordnet.princeton.edu/wordnet/related-projects/
Look at this one, you might find it particularly useful (http://kylescholz.com)
you can see the live demo here : http://kylescholz.com/projects/wordnet/?text=dog
I hope this helps.
