the point of it

1.One of the uses for an Index is to record the positions of all the words in your text file, so that you can subsequently see which word came in which part of each text. Another is to speed up access to these words, for example in concordancing. If you select one or more words in the index and press WSImage_102_concordance_24, you get a speedy concordance.
2.Another is to compute "Mutual Information" or other statistical scores which relate word types to each other.
3.Or you can use an index to see word clusters.
4.Finally, an index is needed to generate concgram searches.
