are transformed into offsets of elements/words as follows: are transformed into offsets of elements/words as follows:
``` ```
0 9 10 15 0 3 4 6
= = = = = =
3+2+4 1+9 2+3+10 3 3+1 4+2
```
so we can tell that the first article is from word 0 to word 9, and the second article is from word 9 to word 10.
The complete offset representation is as follows:
```
0 9 10 15
0 3 5 9 10 12 15
||| || |||| | || |||
``` ```
