Categorizing a Narrative based on keywords

PetrM — Mon, 27 Feb 2023 22:53:37 GMT

I have a Table containing a Narrative field. I have another table (Categories) with Keyword - Category pairs. I want to add a measure into Table that will search for Keword in Narrative and returns the first corresponding Category it finds. I thought the following could do it

Category = VAR NarrativeText = Table[Narrative] RETURN MAXX( FILTER( Categories, CONTAINSSTRING(NarrativeText, Categories[Keyword]) ), Categories[Category] )

but it returns the following error: "A single value for column 'Narrative' in table 'Table' cannot be determined. This can happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result."

Can I correct the formula or is there a better way to do this?

PetrM , You have to create this as a column; the above formula

or a measure like

Category =
VAR NarrativeText = max(Table[Narrative])
RETURN
MAXX(
FILTER(
Categories,
CONTAINSSTRING(NarrativeText, Categories[Keyword])
),
Categories[Category]
)
