Summarize keywords into genera

Does anybody know a service or algorithm that summarizes keywords into genera?

For instance

• cola
• fanta
• sprite
• water

turns into

• Drinks

and

• cola
• fanta
• bread
• sprite
• water
• coffee

turns into

• drinks
• meals

or

• foodstuff

 

Google Keyword Planner Toolmight help. Copy all your keywords to the tool and they're auto sorted to keyword group. But the best suited I think is

Great. Now I know that what I am looking for is called Taxonomy.
