Phase 2, Part 5

Computer neural networks:  Computer neural networks are computer systems in artificial intelligence designed to mimic the interconnected neural units of the brain.  There are thousands of connections that receive excitatory and inhibitory  messages.  The computer neural networks are also designed to gain strength with experience.  An example of computer neural networks could be social robots.  There are also neural connections in viral recognition for computers. 

Language:  Language is the human capacity for a way to communicate through spoken, written or signed words to combine them as we think. There are several different languages around the world.  Some examples are Spanish, Chinese, French, Latin, Arabic, and sign language.  All different languages combine to form different sentences and meanings.

Phonemes:  Phonemes are an essential set of basic sounds.  They are a small segments of sounds to form meaningful words from sounds. For example in the words kit and skill the phoneme is the "k" sound in the word.

Morpheme:  A morpheme is the smallest unit of language that carries meaning.  Morphemes are usually a combination of tow or more phonemes.  However the words "I" and "a" are morphemes as well as phonemes.  The word "unbreakable" contains three morphemes: "un," "break," and "-able."

Grammar:  Grammar is a system of rules that allows us to communicate.  It is the composition of sentences, phrases, and words under the rules of semantics and syntax.  Some grammar parts are the usages of commas and the structure of sentences with nouns, verbs, and adjectives.

Semantics:  Semantics are a set of rules we use to derive meaning and relationships from morphemes, words, and sentences.  There are denotations (direct meanings) and connotations (implied meanings).  For example the phrase "Raining cats and dogs" can have two meanings derived from semantics.
