# Installation
```shell
pip install promptcraft
```

# Character Editing
Character-level Prompt Perturbation\
`CharacterPerturb` class for manipulating character in a sentence
```python
from promptcraft import character

sentence = "Natalia sold clips to 48 of her friends in April, and then she sold half as many clips in May."
level = 0.25  # Percentage of characters that will be edited
character_tool = character.CharacterPerturb(sentence=sentence, level=level)
```
## Character Replacement
Randomly replace `level` percentage characters from the sentence
```python
char_replace = character_tool.character_replacement()
```
## Character Deletion
Randomly delete `level` percentage characters from the sentence
```python
char_delete = character_tool.character_deletion()
```
## Character Insertion
Randomly insert `level` percentage characters to the sentence
```python
char_insert = character_tool.character_insertion()
```
## Character Swap
Randomly swap `level` percentage characters in the sentence\
NOTE: including self-swapping
```python
char_swap = character_tool.character_swap()
```
## Keyboard Typos
Randomly substitute `level` percentage characters in the sentence
with a randomly chosen character which is near the original character in the Keyboard (USA Full-size Layout)\
NOTE:\
(1) We applied `keyboard_distance=1`, i.e., the nearest character, number, or samples.\
(2) If it is a character, we randomly chose lowercase or uppercase.
```python
char_keyboard = character_tool.keyboard_typos()
```
## Optical Character Recognition
Randomly substitute `level` percentage characters in the sentence with a common OCR map error
```python
char_ocr = character_tool.optical_character_recognition()
```

# Word Manipulation
Word-level Prompt Perturbation
`WordPerturb` class for manipulating words in a sentence

NOTE: the number of words in a sentence is only the valid words without considering spaces, special symbols, and punctuations
```python
from promptcraft import word

sentence = "Natalia sold clips to 48 of her friends in April, and then she sold half as many clips in May."
level = 0.25  # Percentage of words that will be manipulated
word_tool = word.WordPerturb(sentence=sentence, level=level)
```
## Synonym Replacement
Randomly choose $n$ words from the sentence that are not stop words.\
Replace each of these words with one of its synonyms chosen at random.\
Problem 1: Without any synonyms\
Problem 2: Fewer positions than needed positions
```python
word_synonym = word_tool.synonym_replacement()
```
## Word Insertion
Find a random synonym of a random word in the sentence that is not a stop word.\
Insert that synonym into a random position in the sentence.\
Do this $n$ times.
```python
word_insert = word_tool.word_insertion()
```
## Word Swap
Randomly choose two words in the sentence and swap their positions.\
Do this $n$ times.
```python
word_swap = word_tool.word_swap()
```
## Word Deletion
Each word in the sentence can be randomly removed with probability $p$.
```python
word_delete = word_tool.word_deletion()
```
## Insert Punctuation
Randomly insert punctuation in the sentence with probability $p$.
```python
word_punctuation = word_tool.insert_punctuation()
```
## Word Split
Randomly split a word to two tokens randomly
```python
word_split = word_tool.word_split()
```

# Sentence Paraphrasing
Sentence-level Prompt Perturbation\
`SentencePerturb` class for directly manipulating a sentence
```python
from promptcraft import sentence

sen = "Natalia sold clips to 48 of her friends in April, and then she sold half as many clips in May."
sentence_tool = sentence.SentencePerturb(sentence=sen)
```
## Back Translation by Hugging Face
Back translate the sentence (English $\rightarrow$ German $\rightarrow$ English) via 🤗 Hugging Face MarianMTModel 
```python
back_trans_hf = sentence_tool.back_translation_hugging_face()
```
## Back Translation by Google Translator
Back translate the sentence (English $\rightarrow$ German $\rightarrow$ English) via Google Translate API
```python
back_trans_google = sentence_tool.back_translation_google()
```
## Paraphrasing
Paraphrasing the sentence via [Parrot Paraphraser](https://github.com/PrithivirajDamodaran/Parrot_Paraphraser) 
considering\
(1) **Adequency**: Is the meaning preserved adequately?\
(2) **Fluency**: Is the paraphrase fluent English?\
(3) **Diversity**: (Lexical / Phrasal / Syntactical): How much has the paraphrase changed the original sentence?
```python
sen_paraphrase = sentence_tool.paraphrase()
```
## Formal Style
Transform the sentence style to Formal
```python
sen_formal = sentence_tool.formal()
```
## Casual Style
Transform the sentence style to Casual
```python
sen_casual = sentence_tool.casual()
```
## Passive Style
Transform the sentence style to Passive
```python
sen_passive = sentence_tool.passive()
```
## Active Style
Transform the sentence style to Active
```python
sen_active = sentence_tool.active()
```

# Parallel Processing
Since all the methods are executed on the CPU, 
they can be performed in parallel using the `multiprocessing` package.
