The slideshow below gives step-by-step instructions on creating a workflow in Argo. The example workflow is a biological entity tagger that takes PubMed IDs as input and produces XMI/XML files that contain the corresponding PubMed abstracts and a set of annotations including syntactic (Sentence, Token) as well as semantic (Proteins, DNA, RNA, etc.) annotations.
Use the navigation arrows to move between slides.
A new window that has opened allows you to draw a block diagram representing a workflow. Argo's library of components, shown on the left-hand-side panel, displays the available processing tools that the user can choose from. They are categorised into Readers, Analytics, and Consumers. The middle area is a canvas for the diagram.
Argo switches automatically to the Processes view. Here, you can track the progress of your workflow's execution. For workflows that include user-interactive components, progress will pause at some point, and the right-hand side panel will display prompts, e.g., buttons or hyperlinks, which the user needs to click/follow before the execution can proceed. A completed execution will be indicated by a status of "Finished", after which the user can check for results.
The workflow was designed to save XMI files into your document space. You can browse your documents by switching to the Documents view. Navigate to the folder where you saved the XMI files. You'll be able to perform several actions on one or more documents. Download a sample document and investigate the results. You'll notice that the file contains the original text and multiple annotations.
