Dr. James Cooke Brown invented a language called Loglan in 1955. By the early 1970s, the project had matured to the point where the language was getting close to its design goals. Some newcomers joined the project, including myself. I was able to devise a version of the grammar which finally met Loglan's goals. I've used what I learned on that research project, and combined it with what Arthur C. Clarke told us was possible in The Moon is a Harsh Mistress and 2001. Now, you'll get to see what you get when you cross Loglan and English.
JCB-English is a language much like English, except that (a) there are some changes to the grammar, and (b) the grammar rules are really rules, as opposed to what in English are called rules. Verbs go first, and everything is in present tense. Here's a sample:
English: I go to the store.
JCB-English: go i the store
Each time you enter something, it will be taken as a command, a statement, or a question. If the entry is a command, then the command will be executed. If the entry is a question, and JCB has the answer, then it will answer the question. Note that in this test version, there is so far no knowledge about the world present in the system. Last, if you make a statement, and the statement is plausible, the knowledge will be retained. Note that plausibility is in the eye of the beholder. In this case, since you're talking to a computer, anything that's not self-contradictory is plausible.
In this sample system, you get your own knowledge base. The knowledge base will be retained for some amount of time. The system is currently single-user, so don't expect miracles of cooperative decision-making. You get to interact one-on-one with JCB as it (he?) evolves.
When a new workspace is created, it has one operator-level user, named "operator", with
"secret" as the password. Log in using i am operator with password 'secret'.
