During and after submitting a text analysis job, you can view job status and results on the "Results" page.
Right after submitting a job, depending on how fast the job is computed, you can probably see the job listed in the "Active Job" section. You can also see all the active jobs submitted by you.
After the job is finished, you can see the job is listed in the "Completed Jobs" section. Click on the job name to see its result.
On this demo job result page, I clicked on the "topic_tagcloud.html" link to see the tag cloud of the topics.
