To build vocabulary profiler, follow these steps:

1. Upload your text and optionally your customized word list;
2. Decide on automatic or manual word segmentation;
3. Once the text is segmented into N-grams, select those N-grams for profiling. If you choose automatic segmentation, you need to select from bigram, trigram and quadrigram lists, respectively.
4. Obtain both character and vocabulary profiles.
