"[Solved] Assigning IDs to tokens in word vector."

I have this word vector:



What i want to do is copy all the tokens from the top x-axis and align them next to their appropriate IDs.

For example, the token 'actual' (on the top x-axis) has the value of 0.366 and id of 3006. What I want is for the token 'actual' to be aligned next to its id. So in this case row 45 would go: id (3006), token (actual).



Hope all this makes sense.

Thanks in advance for your help,

    Hi Alex,

    if I understand you correctly you want to De-Pivot the data (search Pivot on the internet to understand the operation). For an example see the process below. The regular expression in the attribute_name parameter of De-Pivot selects all attributes but text and id.

    Best regards,
