Knowledge Explorer version 3.3

1. pronouns are $ variables
For example:
Mary has sex=female
$she = Mary
$she has age=21, profession=nurse

2. syntax change to avoid ambiguity
A sentence which follows a prepositional phrase must be
enclosed in braces, e.g.:
at space=home,time=Sunday 10:00 am { John do walk }
Mary do say to John { I do want Bill do go to the store }

3. scrolling windows

The UNIX and Linux versions of Knowledge Explorer use the
X Window System. The display managers available with this
system usually support scrolling console windows.

The Windows 98/95/NT/3.x version of Knowledge Explorer uses
the Windows Icon graphics system. This system does not
currently support scrolling console windows, but the next
update will. As soon as the update is released, I will update
Knowledge Explorer v3.3.

4. changed relation output file

I made two significant changes to .rel output file:
it includes the relation definition
it is easier to read
For example, KEHOME/help/phonebook.rel is the output
produced by the Relation and File|Save menus of the
KE input menu.

5. changed tabula_rasa hierarchy

tabula_rasa is an entity-characteristic-relation hierarchy:
existent
/ entity
/ characteristic
// attribute
// action
// relationship
/ relation

KR keywords are relationships
For example:
relationship
/ verb
// isa
// is
// has
// do
// isin
/ conjunction
// causes
// means
