     20Enhance hypernym detection to provide better results.
     21
     22 * Download [[htdocs:bigdata/ia161-hyper.zip|prepared scripts and data]]
     23 * Unzip, `cd ia161-hyper` and run {{{./hyper.py}}}
     24 * The script reads file {{{vstup.txt}}} (each line is word|definition) and outputs hypernym for each word.
     25 * Default approach is naive: ''first noun in definition is hypernym''
     26 * Update the {{{find_hyper()}}} function in `hyper.py` to provide better results.
     27 * Upload updated script plus the output.
