The corpus being used in this English implementation of BC5 contains over 3,500 parsed sentences, which means that it should be able to parse tens or even hundreds of thousands of English sentences correctly; but this is no guarantee that it will be able to parse any particular sentence you type because the number of possible sentences in any language is for all intents and purposes infinite.
Although this implementation parses pretty well, it is still weak in query handling because so much special code is required to handle all the kinds of questions people can ask in English. I (Chaumont Devin) will be working to improve this as I find time.
BC5 is interactive but does not initiate conversations, so it will be up to you to get your session going. You might begin by asking what time it is, or, "Where are you?" or some other simple question to get started.
BC5 will be fun for two kinds of people, namely (1) the serious student of linguistics who will want to see his sentences diagrammed in real time, and (2) the casual user who wants to get some entertainment out of conversing with a computer.
