Similarly, in the example mentioned earlier, when describing a forecast for a day with expected south winds, texts in the group can use either "south wind" or "southerly" to indicate this fact but no texts would verbalize it as "wind from west", and therefore these expressions will be assigned to different semantic clusters.
it is important to note that the phrase "wind from west" may still appear in the texts, but in reference to other time periods, underlying the need for modeling alignment between grouped texts and their latent meaning representation.
