Text Analysis with NMF

NMF analyzes text effectively by introducing context through combining attributes, enhancing explanatory power.

NMF is especially well-suited for analyzing text. In a text document, the same word can occur in different places with different meanings. For example, "hike" can be applied to the outdoors or to interest rates. By combining attributes, NMF introduces context, which is essential for explanatory power:

  • "hike" + "mountain" -> "outdoor sports"

  • "hike" + "interest" -> "interest rates"
