What
software is installed during the FreeText Web Service installation
?
The FreeText Web Service installation
installs the latest Java Development Kit and Java Runtime
Environment, the Jakarta Tomcat servlet engine, and IAT's
marking engine and web service software.
Why
does the web service installer need to be specifically compiled
for my server ?
The Free Text Web Service must
be specifically compiled for the computer where it is to be
installed. This is because the computer name and Tomcat port
form part of the web service configuration. You must supply
Intelligent Assessment Technologies with the name of the computer
where the web service is to be installed, and the port which
Tomcat will use (we recommend the default port of 8080 be
used). You will then be supplied with a custom "Web Service
SetUp.exe" installer for that computer. You can find the computer
name on the "Computer Name" tab of the system properties applet.
With Windows XP, you can find this under : Start ->Settings->
Control Panel-> System
Do
I have to install Tomcat at port 8080 ?
We recommend you use the default
port of 8080. If you choose to install Tomcat at a port other
than 8080, you must inform Intelligent Assessment Technologies
in advance, as this will impact on the generation of "Web
Service SetUp.exe".
How
do I verify that Tomcat is running ?
You can check that Tomcat is
running by loading the following URL in a browser on the installation
computer :
http://localhost:8080/
How
do I install the license file ?
Once installation is complete,
you will need to install the license certificate provided
by Intelligent Assessment Technologies. To proceed, navigate
to C:\Program Files\Apache Software Foundation\Tomcat 5.5\bin
and double click on installWebServiceLicense.bat (The
path may be different if you chose a different install directory).
The Licensing Wizard will launch. Follow the on-screen instructions.
The
web service test fails. Why ?
The most likely cause is that
Tomcat is not properly configured. Select :
Start->Programs-> Apache
Tomcat 5.5 -> Configure Tomcat
Select the StartUp tab, and
add \bin to the end of the default Working Path, such
that (if you chose the default installation directory) it
now reads :
C:\Program Files\Apache Software
Foundation\Tomcat 5.5\bin
Click on the "Apply" button.
Try the test again. If you still have a problem, contact IAT
support.
What
is the WSDL for the web service ?
The WSDL file for the web service
is accessible through the server when Tomcat is running via
the following URL on the server :
http://localhost:8080/axis/services/IATWebService?wsdl
Do
I need to install the web service for FreeText Author to work
?
No, FreeText Author has it's
own version of the marking engine included.
Why
have top-level mark scheme answers and model answers as well
?
Think of the top-level mark
scheme answers as specifying the mark scheme at the level
of detail a human marker would require. However computerised
marking requires a more detailed mark scheme than a human
marker would require. For example, a simple mark scheme answer
such as :
Cell A is bigger
would be easily understood and
applied by a human marker, but for the purposes of computerised
marking we might need to specify that :
Cell A has a larger surface
area
Cell A's perimeter is longer
are also acceptable variations
on the top-level mark scheme answer. To maintain readability
of the mark scheme, we do not require you to list all these
specific variations in the top-level mark scheme. Rather,
we have adopted the idea of having each top-level mark scheme
answer associated with one or more specific model answers.
The specific model answers detail exact acceptable wordings
for the corresponding mark scheme answer, and are the basis
from which the templates are generated.
What
is the difference between "Viewing matching responses"
mode and "Viewing all responses" mode ?
When you mark the responses
in "Viewing matching responses" mode, only the templates for
the current top-level mark scheme answer are applied (i.e.
the templates for the currently listed model answers). Therefore
when a response is shown in green this indicates that it has
been matched by one of the associated model answers. In
this mode, you are concerned only with whether or not the
current model answers match the associated responses.
When you mark the responses
in "Viewing all responses" mode, all the templates in the
mark scheme are applied. Therefore when a response is shown
in green in this mode it indicates that the response has been
awarded the same mark as was awarded during human marking.
In this mode, you are concerned with whether or not the
mark scheme as a whole results in the correct mark being awarded
to all the responses.
How
do I add in a 'do NOT accept' mark scheme answer ?
If you want to add in a 'do
not accept' mark scheme answer, click on the icon below where
it says "Do NOT accept" in the mark scheme panel, and type
in the text of the mark scheme answers as normal.
What
process do I follow to create a computerised mark scheme ?
See the diagram below.
Why
do I need to use the human marking dialog to mark the sample
responses ?
Key to the way that FreeText
Author works is that human marking involves more than just
awarding a mark. It involves specifying which (if any) part(s)
of the mark scheme a response matches. This enables FreeText
Author to organise the responses into 'folders', each folder
associated with a top-level mark scheme answer.
Associating responses with the
top-level mark scheme answers they should match greatly simplifies
the task of creating appropriate model answers (and hence
templates). It means you can concentrate on creating and modifying
the necessary model answers for one mark scheme answer at
a time - and test only against the responses you know should
be matched. You repeat this process for each mark scheme answer
in turn to complete the mark scheme.
