Is there a key word generator?

[MarkusEng1998]

Is there a way, e.g. an existing custom function, to generate key words (nouns) from a field. I don't know the key words, so this function would identify the key words for me.

I could brute force this by parsing each field by word, and counting the instances of each word. But I would get a lot of irrelevant words: a, the, at, is, etc.

In the meantime, I have been generating this list of key words manually.

Any suggestion is appreciated!

Hi @MarkusEng1998 ,

If you have a Premium Capacity or Premium-per-User licence you can use the in-built AI capabilities in Power Query:

There are generic keyword/keyphrase models available, as well as sentiment evaluation etc.

Other than that, you will need to go for the parsing option and use a 'word exclusion' list to avoid the AT's and THE's etc.

You may find Chris Webb's attempt at this type of thing a useful starting point, but make sure to red Frank's comments at the end to get correct counts:

My data source is an Excel export, so I get the error, Cannot convert a value of type Table to type List, when I apply the first step: Lines.ToText(Source, " ")

Hi @MarkusEng1998 ,

I think you would need to use a technique similar to this:

If you adjusted that technique so it resolved to a single bundle of words in the query, rather than to a table cell, that would be the same starting point as Chris.

Thank you, @BA_Pete  for the lead!
