The MAT UI requires that you be able to run a Web server. The Web
server software is included with the MAT distribution.
Instructions for starting and managing the Web server can be found
here. The Web server may also
start up a second server for the Java Carafe engine, so that large
tagging models don't have to be loaded every time you request that
a document be tagged via the MAT UI.
We're aware that in some environments, you won't be able to run
your own Web server. Unfortunately, the resources we have to
devote to MAT do not permit us to create a server-free full
version of MAT. Here's what you won't be able to do, and how you
might work around it:
Without the Web server, you
be able use the MAT UI to hand-annotate documents. You can get
around this limitation in one of two ways.
First, you might try to use the MAT standalone viewer. This
viewing and annotation. However, you'll need your own Web server,
and you'll need a developer to integrate the standalone viewer
into your tool, and manage the annotated documents in whatever
form you choose to manage them.
Second, you may have your own hand-annotation tool. If you do,
you have two options: either ensure that the tool can read or
write documents that MAT can understand, or augment MAT to
understand the format of the documents your annotation tool
creates. There's a Java API, for instance, that you can use to
read and write MAT documents, and there's documentation on the MAT
document format. However, your simplest option is most likely to
read and write in-line XML, if possible, since MAT has a fairly
sophisticated understanding of in-line XML. The documentation on readers and writers will
tell you more. (It's also possible to write a new reader/writer
and add it to MAT, but explaining how to do that is beyond the
scope of this documentation.)
Obviously, if you're building a corpus of annotated documents, and you don't have a hand annotation tool, you'll be out of luck
Without the Web server, you won't able to control the MAT engine via the MAT UI to perform any automated processing of documents. This is not a huge problem, since all the MAT engine operations are available via the command line using the MATEngine tool.
Without the Web server,
you won't be able to view or control MAT workspaces via the MAT
UI. This is a bit more of a problem, since the UI manages access
to the workspaces during hand annotation. You'll have to be sure
you only annotate documents that reside in the relevant folders in
the MAT workspace, and save those documents back to the workspace.
We can't guarantee that this is the extent of the consequences of
not being able to run the MAT Web server. We encourage you, if at
all possible, to find an environment, such as a virtual machine,
where you're permitted to run the server.
