Changs between WordNet 1.6 and WordNet 1.7

GENERAL

	The Macintosh platform is no longer supported.

	The DOS platform is no longer supported.

DATABASE CHANGES

	Removed "marked" adjectives (were noted with "(m)" after word)

	index.sense (sense.idx on PC) file no longer has adjective
	modifiers - ("(p)", "(a)", "(ip)") after word in sense key. 

	Synsets in 1.7 are located at byte offsets that are unique to
	1.7, and do not map directly to 1.6 byte offsets.  The Sense
	Map package contains a mapping of 1.6 to 1.7 senses and
	synsets.

	The ordering of senses is different.  What was "Sense 1" of a
	word in 1.6 will not necessarily be "Sense 1" in version 1.7.
	The Sense Map package contains a mapping of 1.6 to 1.7 senses.

LEXICOGRAPHER FILES CHANGES
(Note - the lexicographer source files are not included in the
standard Database Package)

	Removed "marked" adjectives (were noted with "(m)" after word)

	In preparation for WordNet 2, we have started to enter some
	links between nouns and verbs.  These links are present in
	the lexicographer files, however the links are not present in
	the WordNet 1.7 database.  All of these links are represents
	is "+" followed by a single, lower-case letter a-x.  These
	should be ignored. 

SEARCH CHANGES

        Added "Coordinate Terms" search for verbs.

        Print number of times each sense is tagged (in our corpus of
        semantically tagged texts) on "Overview". 

        Removed "Related Synsets" search for nouns.

        Changed holonym/meronym search to properly inherit parts.

WNB CHANGES

        Added automatic line wrapping on output buffer.

	Button-2 click (middle mouse button) now has same effect as
	shift-click.  When button-2 is clicked on a word in the search 
	results buffer, that word becomes the new search word, and an
	"Overview" search is automatically performed. 

	Adjective search relabeled "Synonyms/Related Nouns"

	Adverb search relabeled "Synonyms/Root Adjectives"

	Command "wnb arg" uses 'arg' as search word and automatically
	performs "Overviw" search on 'arg' when it starts up.

USING 1.7 DATABASE WITH 1.6 SOFTWARE

        In general, the 1.7 database can be substitued for the 1.6
        database, as there are no changes to the file format.  This
        has been tested with the 1.7 command line interface, but not
        with the graphical interface, due to Tcl/Tk differences
        between the versions.  But with a little work, the 1.6 'wnb'
        command should also work with the 1.7 database.

	The 1.7 database does not use the files "cousin.tops" and
	"cousin.exc", however the 1.6 library expects these files to
	exist.  If you want to use the 1.7 database with any code
	compiled with the 1.6 library (libwn.a), then you must create
	the files "cousin.tops" and "cousin.exc" in the same directory
	in which the database files exist (the Unix default location
	is /usr/local/wordnet1.7/dict).  The files don't need to have
	anything in them, so on Unix systems, for example, the "touch
	cousin.tops cousin.exc" command will do the trick.
