Question : Grouping related words in excel automatically

Hi, thanks in advance for your help. I appreciate it greatly.

I have an excel sheet with tens of thousands of terms and statistics. Right now it's not in any particular order. How would I automatically group related words together (based purely on root words)? I.e. all term strings containing "computer" would be grouped together, all terms containing "pda" will be grouped together, etc.

Also a more advanced question would be if there is a way to group words by semantic relationships as opposed to purely by root word. I.e. "apples" and "oranges" are types of fruit, is there some sort of tricked out function in excel (or any other program) that can arrange words into groups based on this type of relationship? Thanks very much.

Answer : Grouping related words in excel automatically

What you need here is something like prolog or lisp, an AI programming language. It should be possible to do this in excel also but it would be complicated and tedious especially since all relationships in any AI system must be defined somehow. Better system can relate multiple items.
i.e. Granny Smith -> Apple -> Fruit
     Valencia -> Orange -> Fruit
Therefore Orange and apple are related by a degree of seperation one, Granny Smith and Valencia are related by a degree of two. I guess the idea would/could be relationships weaken but do exist as items move from their root.

Try searching for a predicate language.
