In this lesson, several useful linguistic tools useful for common language learners are discussed. They are not always accurate, so keep in mind.
Many of the tools introduced are written in Python, which is an important language in machine learning and easy to learn.
If you don't know Python, please try this:

Diacritisation
In Arabic writing system, diacritics indicate the accents, but they are often omitted for writing fluently. The process of restoring diacritics is called diacritisation.

Lemmatisation
When you search a word in inflected form, the dictionary program can show you the result as lemma, during which the lemmatisation is done.

Pitch-Accent Marking
In Japanese and other languages, the pitch-accent is important on distinguishing different words. They are unwritten and required.

Stress Marking
In Russian and other languages, the stress is important on distinguishing different words. They are usually omitted.

Part of Speech Tagging
It tags words in the sentence with parts of speech. Some of them can draw parse trees.
Multiple languages:
- Natural Language Toolkit https://www.nltk.org/
- spaCy https://spacy.io/
- Stanford Log-linear Part-Of-Speech Tagger https://nlp.stanford.edu/software/tagger.shtml
Word Segmentation
In some languages, words are not separated by spaces, for example: Chinese, Japanese, Lao, Thai. In Vietnamese, spaces are used to divide syllables instead of words. This brings about difficulties for computer programs like VocabHunter, gritz and text-memorize, where words are detected only with spaces.
The solution is called “word segmentation”, which detects words and insert spaces in between or put the segmented words into a list.
