We need not construct our language from scratch. Among the many already existing con-langs there are two that look very promising: Lingua Franca Nova (LFN) and Loglan/Lojban.

LFN was created as an auxiliary language that people from Europe and the America's can learn easily*. The Big idea behind LFN is that we should construct an auxiliary language using the logic of Creole languages. Recent findings concerning Creole languages give LFN a solid scientific base.
LFN has a simple and regular grammar. It is spelt as it is pronounced. Its vocabulary comes from French, Spanish, Italian, Portuguese and Catalan**. It can be pronounced like Italian (very nice) Spanish (not bad) or Portuguese.

LFN will be used here as the most simple natural language available. If computers can not work with LFN -the most simple case- then we should forget all about natural language processing.***

Loglan* is definitely not natural. It is really weird. It is so by design. More than 50 years ago a (slightly mad) scientist wanted to test a linguistic hypothesis. To do this he needed a language that was as different as possible from all other languages. He created loglan. Loglan is based on predicate logic. Simply put: Loglan is spoken predicate logic. The Loglan vocabulary was formed by looking for the "largest common denominator" between words in: English, Mandarin Chinese, Hindi, Russian, Spanish, Japanese, French and German. The result is a language with an unnatural grammar and very strange words.

The foundation in predicate logic and its mathematics like precision make Loglan very suited for computer processing**. It was never intended to be so, but it simply turned out that way. If we can not make the computer work with LFN, we can look at Loglan grammar for idea's to make our language more computer friendly.

** The potential of Loglan as an computer language was spotted early on. Robert Heinlein, a grandmaster of science fiction, used it in a 1966 novel.

On first sight Toki Pona is not a logical language (explicit, unambiguous, complete etc.). It's Taoist roots - highly intuitive, extremely ambiguous - make Toki Pona unfit for computer processing. No computer program or PhD thesis will ever be written in it. Toki Pona was created with the exact opposite purpose in mind. It wants cut the verbal foliage that clouds our minds. It aims to succinctly express the core of the human condition. In other words: Toki Pona is the ideal medium for "dark teenage poetry".

However, Toki Pona was constructed according to the Taoist guideline "less is more". It has only 118 words, most of which are semantic primitives, the grammar is simple. This makes Toki Pona a doable language for computer processing (only 118 words + simple grammar).
