Demo of the Document Space Visualization
Choose one interface you want.
Use
Document Creation Interface
This interface will make you be able to create documents with
listed words.
The point of using this interface is let you have choice of
structuring them by which you know the structure of documents.
By creating the document, it would be more understandable how
the document sapce will represent the similarity of documents
and therefore it would be easier to compare the distances between
documents by 2-D and 3-D graphs.
For more information on Document Creation Interface, read Document
Creation Interface explanation.
Use
Document Selection Interface
This interface will make you to select documents from the given
document list.
The point of using this interface is let you see the document
space by easily selecting document set from the list. Selecting
document set quickly will make you see the document space easily
and therefore without having effort you can understand how documents
are represented in the document space and how the document distance
matters in the similarity / dissimilarity of documents. Similary,
document similarity will be represented in 2-D and 3-D graphs.
For more information on Document Selection Interface, read Document
Selection Interface explanation.
Visualization of the Document Space
After the Fastmap algorithm, the 'images'
of objects will be provided. At this point, the system will
transform those images into positions in coordinate system along
X, Y and Z axis. We create this coordinate system as a space
fulfilling with documents in various sizes and types to display
the relationship among these documents themselves.
In order to present the document relationship
in the space, we have created two types of graphic displays
that are 2 dimension document space and 3 dimension document
space. Because human is able to perceive and determine the difference
of any distance between 2 object very well in a plane, we decided
to create 2 dimension document space to better serve viewer's
perception. However, in some cases, it is hard to figure out
the distance between 2 object when a object overlays on the
other. For this reason, we decided to create another type of
representation that is 3 dimension space, which let viewer rotate
the angle of the observing point to an appropriate view.
We believe not only that the 3 dimension
graphic representation will brings a chance for viewers to virtually
experience the document relationship better than the 2 dimension
space but also that the 2 dimension space can give viewers to
measure the different of document distance easier than 3 dimension
space. As a consequence, we shows both 2 and 3 dimension space
in the "ShowGraphSpace" page, so it would be easy for viewers
who want to compare the document relation ship in 2 and 3 Dimension.
