You can start using OVA by visiting its website at [coming soon!]. You can then either:<\/p>\n
^Back to top<\/a><\/p>\n The core feature of OVA, as with Araucaria, is the ability to extract text into a series of premises, which are then used to construct an argument diagram.<\/p>\n Doing this in OVA is very simple:<\/p>\n The software has been designed to safeguard against duplicate premises. That is, you cannot extract exactly the same piece of text twice by accident.<\/p>\n ^Back to top<\/a><\/p>\n In order to indicate support or attack, premises must be connected. This is done by the following procedure:<\/p>\n To create a linked argument (that is, an argument in which two or more premises work together to support or attack another):<\/p>\n ^Back to top<\/a><\/p>\n OVA has a number of built-in schemes, grouped by schemeset. To apply one of these to an argument:<\/p>\n OVA also supports the creation of custom schemes. This can be done in one of two was:<\/p>\n Via Scheme Nodes<\/strong><\/p>\n Via the “Custom Scheme Manager”<\/strong><\/p>\n You can also use the “Custom Scheme Manager” to edit previously created schemes. You can do this by simply clicking on the name of a scheme listed in the manager and changing the details (note: it is not possible to change any of the built-in schemes).<\/p>\n ^Back to top<\/a><\/p>\n Sometimes an analysis requires the addition of a missing premise or enthymeme. These can be easily added:<\/p>\n ^Back to top<\/a><\/p>\n You can delete any premise or scheme node in your analysis by right-clicking on it, and clicking “Delete Node”. Note that deleting a Scheme Node will delete any links that go through it.<\/p>\n ^Back to top<\/a><\/p>\n If you prefer to view the analysis without scheme nodes, you can toggle them on the diagram. To do this, from the “Options” menu click “Toggle Scheme Nodes”.<\/p>\n Note that even with Scheme Nodes turned “off”, they will re-appear when linking premises to allow linked arguments to be created.<\/p>\n ^Back to top<\/a><\/p>\n You can zoom in and out by using the slider at the top of the screen.<\/p>\n ^Back to top<\/a><\/p>\n OVA provides an interface to allow you to save to an ArgDB installation. The version of OVA available on this site connects to an ArgDB server here at the university, which you can save to.<\/p>\n Registering<\/strong><\/p>\n You are not required to register in order to save analyses to our ArgDB server, however we recommend you do register so as to provide an easy method of retrieving all your analyses again. To register, simply click “Register on this Server” and provide a username and password.<\/p>\n Retrieving Analyses<\/strong><\/p>\n In order to retrieve an analysis saved on our ArgDB server, visit http:\/\/argdb.computing.dundee.ac.uk\/get.php?argument=<id><\/strong>, where <id> is the ID number you were provided with in step 5 above. Alternatively, click here<\/a> and enter the ID in the box.<\/p>\n If you wish to obtain an AIF file from your analysis without saving to ArgDB, you can do this by clicking “Save to local file” in the “Save” menu.<\/p>\n You can also save a JPEG image of your diagram, by clicking “Save to image” in the “Save” menu.<\/p>\nExtracting Text<\/h2>\n
