Theory

In NLP we've the following tasks to do:

• Look up - look up in a directionary (to find an antonym or synonym or definition)
• Machine translation - translate a text or word from one language to another
• Parsing - extract specific information from a word or text
• Part-of-Speech-Tagging - Search to corresponding part-of-speech (pos) tag for a word (there are different pos tag sets)
• Segmentation/Tokenization - Split the text or sentence by words or sentences
• Spell checking - check to correct writing of a word or text
• Stemming - Extract the stem of a word
