EMELD Arizona:

Since Santa Barbara


Focus on morpho
-
syntax


Decided to build ontology (to be
discussed later in this talk)


Decided to build supporting tools

–
smart search engine (Hedwig)

–
editor


Some work on xml markup

The Problem


Currently there is no general way for
researchers in the endangered
languages community to
electronically share information.


The Web is the most likely tool that
could provide a solution.


The current WWW is not adequate.


An Example from the WWW:

Further Complications


What about other data formats?

–
lexicons

–
grammatical descriptions

–
(comparative) word lists

–
paradigms

–
etc.

Warumungu Description

'Grammatical case suffixes' are those which
express grammatical relations (subject,
object, indirect object), like /karriny
-
ji/ in
(4). A noun without a case suffix is
interpreted as having Absolutive case
-

/nanttu/ in (4) and /wangarri/ in (5)
-

or
as being the main predicator, or as
agreeing with some argument with
Absolutive case
-

/kumppu/ and
/pulyurrulyurru/ in (5).

(from J. Simpson 1998)

Karriny
-
ji +ajjul nyirri

-

place

'He placed a big red hill.' [JS:PND:RS]

Chichewa Description

Other elements that appear as verbal
prefixes include modals
–

for
instance,
-
ngo
-

'just, merely'
–

as
well as directional elements
-
ka
-

'go'
and
-
dza
-

'come'. These are placed
in the immediate pre
-
OM position,
after the tense. This is shown by the
following:

(from Mchombo 1998)

A Solution


Take advantage of new Web
technology



Build a community of practice on the
Semantic Web



What is the Semantic Web?


The Semantic Web


New markup: <xml>, <rdf>, <owl>



New tools: smart search engines




ontologies, new editors



Meaning is encoded explicitly.



Pages are interpreted by a reasoner.

An Example from the Semantic
Web


New markup adds functionality to
existing <html> documents.


Example:

<rdf:Description rdf:about="
#A110604
">



<rdf:type rdf:resource="
#State
" />



<NS0:name>
Tennessee
</NS0:name>


</rdf:Description>

<rdf:Description rdf:about="
#876555
">



<rdf:type rdf:resource="
#Language
" />

The Ontology


Crucial component of the Semantic
Web


A resource that explicitly defines
what entities can exist in a domain,
i.e., the endangered languages
community


A resource that defines what
relations hold between entities


demo

OWL Web Ontology Language


Analogous role of <html> on the
WWW


The most current “standard”
Semantic Web language


Under development at the W3C:

Facilitating Tools

Editors for composing Semantic Web

A Good Data Model for Creating a
Community of Practice


Language data should be searchable
and comparable
—
broad access
(centralized).


Authors or communities want control
over their data (local/distributed).


Local control should be balanced with
data interoperability (Semantic
Web).


Centralized Model

Community Requirements


No need to standardize your
terminology or abandon tradition.


No need to learn <xml> (it doesn’t
hurt!)


Use EMELD tools to put your data on
the Semantic Web


Maintain your data
