Artha(1)		  Artha	- The Open Thesaurus		      Artha(1)

NAME
       Artha - An cross-platform thesaurus based on WordNet

DESCRIPTION
       Artha  is an open thesaurus based on the	WordNet	database, created with
       simplicity in mind. Once	executed, Artha	monitors  for  a  user	preset
       global  hotkey combination. When	the user selects some text in any win-
       dow, and	presses	this hotkey combo, Artha looks	up  WordNet  thesaurus
       for the selected	text and pops-up with the results.

       When executed for the first time	Artha tries to register	a hotkey auto-
       matically, in the order,	Ctrl + Alt + [W	or A  or  T  or	 Q].  You  can
       view/change  it	via the	'Hotkey' button	in the toolbar.	It can also be
       disabled.

DEFINITIONS
       Definitions are categorized based on the	PoS (Part of  Speech  -	 Noun,
       Verb,  Adjective	and Adverb). Apart from	showing	the definitions/senses
       of a searched string with usage examples, Artha	also  shows  a	word's
       relatives  like	Synonyms,  Antonyms,  Derivatives, Pertainyms (Related
       noun/verb), Attributes, Similar Terms, Domain/Domain Terms, Causes, En-
       tails,  Hypernyms (is a kind of), Hyponyms (Kinds), Holonyms (is	a part
       of), Meronyms (Parts).

   SENSES AND RELATIVES
       A word can have more then one sense i.e.	it can convey more than	a sin-
       gle  meaning/definition.	 Relative  words are words that	are related to
       one or more senses of the searched word,	by a  relationship  like  Syn-
       onym,  Derivative,  etc.	 To know which all sense a relative is related
       to, just	select the it, the corresponding senses	it maps	to  are	 high-
       lighted.	 As  per WordNet, depending on the number of senses a word has
       (polysemy count), it's familiarity is  determined.  It  gets  displayed
       next  to	 the  PoS in the definition area. There	are 7 types: extremely
       rare, very rare,	rare, uncommon,	common,	familiar,  very	 familiar  and
       extremely familiar.

MODES
       Artha has 2 modes. Simple and Detailed. Artha enters Detailed mode when
       the 'Detailed' button in	the toolbar is pressed.	When toggled again, it
       returns	back  to simple	mode. For relatives like Antonyms, Pertainyms,
       Hypernyms, Hyponyms, Holonyms and Meronyms, where more than  one	 level
       of  relatives  may be present, is showed	in a tree fashion, in detailed
       mode. If	in simple mode,	only one level of  relatives  are  shown  even
       when  more  levels are present. E.g. 'rich' has 'poor' and 'lean' alone
       as antonyms in simple mode. While in detailed mode, 'poor' further  in-
       fers broke, skint, etc. which are shown as children of 'poor'.

REGULAR	EXPRESSIONS BASED SEARCH
       Regular	expressions  can be used to search for a term when you vaguely
       know it and want	to locate it in	the thesaurus. Artha's regular expres-
       sion  pattern  closely follows Wildmat syntax by	Rich Salz owing	to its
       simplicity.

	      *	(wildcard) matches any number of (including 0) unknown charac-
	      ters

	      ?	(joker)	matches	one unknown character

	      [...]  (range)  matches  one  unknown character within the range
	      specified

	      {m, n} (limits) upper & lower limits of the number of characters
	      in a range

	      [^...]  (not  in	the  range)  matches one unknown character NOT
	      within the range specified

	      EXAMPLES:

	      Expr. `cro*p` means the term you	want  to  corner  starts  with
	      `cro`  and  ends	with `p` while the number of characters	in be-
	      tween are	unknown. It fetches crop, crop up, croup, crock	up and
	      crow step.

	      Expr.  `*chester`	 means the searched word ends with a `chester`
	      while the	beginning and its number characters  are  unknown.  It
	      fetches  chester,	manchester, rochester, winchester and toy man-
	      chester.

	      Expr. `can????r` means the term sought  starts  with  `can`  and
	      ends  with `r` while you are sure	that there are 5 unknown char-
	      acters in	between.  It fetches canister and cannular.

	      Expr. `andre*[x|y|z]` means the word searched  for  starts  with
	      andre  and  ends	with either an x or y or z, and	there could be
	      any number of terms in betweem these. It fetches andre  malraux,
	      andrei tarkovsky,	andres martinez, etc.

	      Expr. `a[c|d|e]{2,}` means the word looked for starts with a and
	      then there are minimum 2 or more occurances of c,	 d  or	e.  It
	      fetches acc, accede, ace,	add, ade and aec.

OPTIONS
       Look-ups	 made  in  Artha are stored permanently	as a per-user setting,
       and can be saved	via the	popup menu of the search bar or	can be cleared
       too.   Other  options  like  showing term familiarity based on polysemy
       count, display of status	icon, etc. can be changed via the Options win-
       dow.

NOTIFICATIONS
       Should  the  user  prefer passive desktop notifications (balloon	tips),
       rather than the application popping up with the definitions, it can  be
       done by enabling	Notifications. This is done via	the Notify tool	button
       or by right-clicking on Artha's system tray icon, and tick off the 'No-
       tifications' check box in the menu. When	notifications are enabled, and
       the user	selects	text in	a window and presses the hotkey	 combo,	 Artha
       takes  the  prime  definition  of that term from	WordNet	and shows that
       definition as a system tray notification.

       Note: For the notifications feature to be present, notify library's bi-
       nary (libnotify.so.1) should be available on your system. If not, Artha
       will not	expose the feature at all. Also	the notification-daemon	should
       installed for the notifications to show up.

SUGGESTIONS
       Suggestions  is	a  feature that	gives out possible near	matches	when a
       misspelled word is searched for.	To  have  this	feature,  your	system
       should  have  libenchant	binary (libenchant.so.1) installed and an Eng-
       lish dict file for the spell engine to refer (locale doesn't matter).

AVAILABILITY
       Artha has a World Wide Web site at  http://artha.sourceforge.net.  From
       this  web  site	users  can  know more about the	Artha project and also
       download	its source and binary distributions for	various	distros.
