RK-A

For this task, we need to make changes in the mapping_phrase_docid where we can identify the KP which contains apostrophe but the header variant does not. They generally contribute to bad KP cases e.g.
1. item 's option -> item options
2. file 's format -> file formats
3. distribution 's version -> distribution versions
4. module 's api -> module api
5. module 's attributes -> module attributes
6. module 's contents -> module contents
7. option 's action -> option actions

These cases are generally tagged out of context and hence, they should be penalized. The penalty can be 0.1 to ensure that they are scored on the lower side of the sim_score band.
Testing to be done with Library Reference.txt & Whirlwind.txt
