NAME
wnb - WordNet window-based browser interface
SYNOPSIS
wnb
DESCRIPTION
wnb() provides a window-based interface for browsing the
WordNet database, allowing synsets and relations to be
displayed as formatted text. For each search word, dif-
ferent searches are available based on syntactic category
and information available in the database.
wnb is written in Tcl/Tk, which is available for Unix and
Windows platforms. This allows the same code to work on all
supported WordNet platforms without modification.
WNB WINDOWS
wnb() was developed with the philosophy that only those
searches and buttons that are applicable at the current time
are displayed. As a result, the appearance of the interface
changes as it is used. Use the standard windowing system
mouse functions to open and close the WordNet Browser Win-
dow, move the window, and change its size.
The WordNet Browser Window contains the following areas,
from top to bottom:
Menubar A menubar runs along the top of the
browser window with pulldown menus and
button entitled File, History, Options,
and Help.
Search Word Entry Below the Menubar is a line for entering
the search word. A search word can be a
single word, hyphenated string, or a
collocation. Case is ignored. Although
only uninflected forms of words are usu-
ally stored in WordNet, users may search
for inflected forms. WordNet's morpho-
logical processor finds the base form
automatically.
Search Selection Below the Search Word Entry line is an
area for selecting the search type and
senses to search. Until a search word
is entered this area is blank. After a
search word is entered, buttons appear
corresponding to each syntactic category
(Noun, Verb, Adjective, Adverb) in which
the search string is defined in WordNet.

WordNet User Commands WNB(1WN)
At the right edge of the Search Selec-
tion line is a box for entering sense
numbers. When this box is empty, search
results for all senses of the search
word that match the search type are
displayed. The search may be restricted
to one or more specific senses by enter-
ing a comma or space separated list of
sense numbers in the Senses box. These
sense numbers remain in effect until
either the user changes or deletes them,
or a new search word is entered.
Results Window Most of the browser window consists of a
large text buffer for displaying the
results of WordNet searches. Horizontal
and vertical scroll bars are present for
scrolling through the output.
Status Line A status line is at the bottom of the
browser window. When search results are
displayed in the Results Window, this
status line reflects the type of search
selected. When there is no search word
entered, your are prompted to "Enter
search word and press return." If the
search word entered is not in WordNet,
the message "Sorry, no matches found."
is displayed.
SEARCHING THE DATABASE
The WordNet browser navigates through WordNet in two steps.
First a search word is entered and an overview of all the
senses of the word in all syntactic categories is displayed
in the Results Window. The senses are grouped by syntactic
category, and each synset is annotated as described above
with _s_y_n_s_e_t__o_f_f_s_e_t, _l_e_x__f_i_l_e_n_a_m_e, and _s_e_n_s_e__n_u_m_b_e_r as dic-
tated by the advanced search options set. The overview
search also indicates how many of the senses in each syntac-
tic category are represented in the tagged texts. This is a
way for the user to determine whether a sense's sense number
is based on semantic tagging data, or was randomly assigned.
For each sense that has appeared in such texts, the number
of semantic tags to that sense are indicated in parentheses
after the sense number.
Then, within a syntactic category, a specific search is
selected. The desired search is performed and the search
results are displayed in the Results Window. Additional
searches on the same word can be performed, or a new search
word can be entered.

WordNet User Commands WNB(1WN)
To enter a search word, click the mouse in the horizontal
box labeled Search Word, type a single word, hyphenated
string, or collocation and press RETURN.
wnb() responds by making a set of Part of Speech buttons
appear in the Search Selection line. Each button
corresponds to a syntactic category in which the search
string is defined in WordNet. At the same time, an Overview
of the synsets for all senses of the search word is
displayed in the Results Window. The Overview includes the
gloss for each synset and also indicates which of the senses
have appeared in the semantically tagged texts. For each
sense that has appeared in such texts, the number of seman-
tic tags to that sense are indicated in parentheses after
the sense number.
The pulldown menus in the Search Selection line list all of
the WordNet searches that can be performed for the search
word in that part of speech. To select a search, highlight
it by dragging the mouse to it, and release the mouse while
it is highlighted. Drag the mouse outside of the pulldown
list and release to hide the menu without making a selec-
tion. Dragging the mouse across the Part of Speech buttons
displays the available searches for each syntactic category.
To restrict a search to one or more senses within a syntac-
tic category, enter a comma or space separated list of sense
numbers in the Senses box before selecting a search.
After a search is selected, wnb() performs the search on the
WordNet database and displays the formatted results in the
Results Window. Whenever search results are displayed, a
button entitled Redisplay Overview is present at the right
edge of the Search Word Entry line. Clicking on this button
redisplays the Overview of all synsets for the search word
in the Results Window.
Changing the Search Word
A new search word can be entered at any time by moving to
the Search Word Entry box, if necessary highlighting it by
clicking, erasing the old string, typing a new one and
pressing RETURN. The Senses box is cleared if necessary, the
Part of Speech buttons applicable to the new search word
appear, and the Overview for the new search word is
displayed.
The middle mouse button can also be used to select a new
search word by placing the mouse over any word in the
Results Window and clicking. The selected word will replace
the text in the Search Word Entry box, and the overview for
that word will automatically be displayed.

To select a new search string collocation from text in the
Results Window, highlight the text with the mouse and press
CONTROL-S.
Interrupting a Search
When a search is in progress the message "Searching...(press
escape to abort)" is displayed in the Status Line. Note
that most searches return very quickly, so this message
isn't noticeable. As indicated, pressing the ESCAPE key
will interrupt the search. The results of the search
obtained before the time the search was interrupted are
displayed in the Results Window.
MENUS
File Menu
Find keywords by substring
Display a popup window for specifying a search of
WordNet for words or collocations that contain a
specific substring. If a search word is currently
entered in the Search Word box, it is used as the
substring to search for by default. The Substring
Search Window contains a box for entering a sub-
string, a pulldown menu to its right for specify-
ing the part of speech to search, a large area for
displaying the search results, and action buttons
at the bottom entitled Search, Save, Print
Dismiss.
Once a substring is entered and a part of speech
selected, clicking on the Search button causes a
search to be done for all words and collocations
in WordNet, in that syntactic category, that con-
tain the substring according to the following cri-
teria:
1. The substring can appear at the beginning or
end of a word, hyphenated string o collocation.
2. The substring can appear in the middle of a
hyphenated string or collocation, but only delim-
ited on both sides by spaces or hyphens.
The search results are displayed in the large
buffer. Clicking on an item from the search
results list causes wnb() to automatically enter
that word in the Search Word box of the WordNet
Browser Window and perform the Overview search.
Clicking the Save button generates a popup dialog
for specifying a filename to save the substring
search results to. Clicking the Print button

list can be adjusted from the Options menu. The default is
10.
Options
Show help with each search

automatically wrapped. This is set by default.
If not selected, a horizontal scroll bar is
