 | Source | What it does | Rules to follow |
 |---|---|---|
 | Bilingual training documents | Teaches the system your terminology and style. | **Be liberal**. Any in-domain human translation is better than machine translation. Add and remove documents as you go and try to improve the [BLEU score](concepts/bleu-score.md?WT.mc_id=aiml-43548-heboelma). |

 | Phrase dictionary | Forces the given translation 100% of the time. | **Be restrictive**. A phrase dictionary is case-sensitive and any word or phrase listed is translated in the way you specify. In many cases, it's better to not use a phrase dictionary and let the system learn. |
 | Sentence dictionary | Forces the given translation 100% of the time. | **Be strict**. A sentence dictionary is case-insensitive and good for common in domain short sentences. For a sentence dictionary match to occur, the entire submitted sentence must match the source dictionary entry. If only a portion of the sentence matches, the entry won't match. |
