It's not what you are looking at that matters, it's what you see.

# Language - natural language processing NLP and other utterances.

I thought I had an NLP Natural Language Processing page. I don't, there's details about it on other pages. But it is time for a separate page.

## Markov chain || discrete-time Markov chain || DTMC

mathematical system that undergoes transitions from one state to another on a state space. It is a random process usually characterized as memoryless: the next state depends only on the current state and not on the sequence of events that preceded it. This specific kind of "memorylessness" is called the Markov property. Markov chain - Wikipedia, the free encyclopedia

## Sentiment analysis

TextBlob stands on the giant shoulders of NLTK and pattern, and plays nicely with both.

TextBlob: Simplified Text Processing — TextBlob documentation
Written text can be broadly categorized into two types: facts and opinions. Opinions carry people's sentiments, appraisals and feelings toward the world. The pattern.en module bundles a lexicon of adjectives (e.g., good, bad, amazing, irritating, ...) that occur frequently in product reviews, annotated with scores for sentiment polarity (positive ? negative) and subjectivity (objective ? subjective).

The sentiment() function returns a (polarity, subjectivity)-tuple for the given sentence, based on the adjectives it contains, where polarity is a value between -1.0 and +1.0 and subjectivity between 0.0 and 1.0. The sentence can be a string, Text, Sentence, Chunk, Word or a Synset (see below).

The positive() function returns True if the given sentence's polarity is above the threshold. The threshold can be lowered or raised, but overall +0.1 gives the best results for product reviews. Accuracy is about 75% for movie reviews.

## Lincos and other things to talk to aliens

Lincos (artificial language) - Wikipedia, the free encyclopedia
The Story of Lincos, the Math-Based Language Created to Communicate With Extraterrestrials - The Atlantic
made up of phonemes, not letters, and governed by phonetics, not spelling. The speech is itself made up of unmodulated radio waves of varying length and duration, encoded with a hodgepodge of symbols borrowed from mathematics, science, symbolic logic, and Latin. In their various combinations, these waves can be used to communicate anything from basic mathematical equations to explanations for abstract concepts like death and love.
