Joining Entries Together (Lemmatisation Lemmas)

  Previous topic Next topic JavaScript is required for the print function  

In a word list, a key word list or a list of collocates you may want to store several entries together: e.g. want; wants; wanting; wanted. Bringing them together means you're treating them as members of the same "lemma" or set -- rather like a headword in a dictionary.


Manual joining

You can simply do this by dragging one entry to another. Suppose your word list has






you can simply grab wanting or wanted with your mouse and place it on want.


(See choosing lemma file if you want to join these to a word which isn't in the list)


A lemmatised head entry has a red mark in the left margin beside it. The others you marked will be coloured as if deleted. The linked entries which have been joined to the head can be seen at the right.




Here we see a word list based on 3-word clusters where originally a good deal had a frequency of 24, but has been joined to a great deal and a good few and thereby risen to 141.


If you cannot see all the items you want to join in one screen, you can do the same thing using function keys.

1. Use F5 to mark an entry for joining to another. The first one you mark will be the "head". For the moment, while you're still deciding which other entries belong with it, the edge of that row will be marked green. Any entries which you then decide to link with the head (by again pressing F5) will show they're marked too, in white. (If you change your mind you can press F5 again and the marking will disappear.)

2. Use F4 to join all the entries which you've marked. The program will then put the joint frequencies of all the words you've marked with the frequency of the one you marked first (the head).


To Un-join

If you select an item which has lemmas visible at the right and press Control/F4, this will unjoin the entries of that one lemma. To unjoin all lemmatised forms in the entire list, in the menu choose Edit | Join | Unjoin All.


tog_minus         Automatic joining


There are two methods, a) based on a list, and b) based on a template.


a) File-based joining

You can join up lemmas using a text file which automates the matching & joining process. The actual processing of the list takes place when you choose the menu option Match Lemmas (Lemmas) in WordList, Concord or KeyWords. Every entry in your lemma list will be checked to see whether it matches one of the entries in your word list. In the example, if, say, am, was, and were are found, they will be stored as lemmas of be. If go and went are found, then went will be joined to go.


b) Auto-joining based on a template

To speed up this lemmatisation process, you can auto-join any of the entries in your current word list which meet your criteria.

Double-click on the Lemmas column as in the shot below,




and a window of Lemma Forms will open up, showing the various components.
