This document provides instructions for building and using a text classification model within Microsoft Azure to analyze text and route it appropriately. It involves the following steps: 1. Building a text classification model in Azure to analyze healthcare feedback text and tag it. 2. Publishing the trained model and using it via the Predict action in Microsoft Flow to classify new text and parse the results. 3. Adding conditional logic and actions to the flow to email specific feedback text to staff or other departments, depending on the model's classification and a minimum score.

Exercise 1 – Build the text classification model
1. From the leftnavigation,expandAIBuilderandselectBuild. SelectTextClassification.
2. Name yourmodel. Because youare workingina sharedenvironmentmake sure toinclude your
name as part of the model name. Thiswill make iteasiertofindlater.ClickCreate.

2. 3. Your screenshouldlooklike the followingimage. ClickSelecttext.
4. Choose healthcare_feedbackforthe entity.

3. 5. SelectTextforthe field. ClickSelectfield. Thisidentifiesthe datathatwill be analyzed.
6. Reviewapreviewof the datathat will be classified. Clicknext.
7. Nowwe will selecttags. ClickSelectTags.

4. 8. SelectTags.
9. SelectCommaas the separator. ClickNext.
10. Reviewthe textandtags. Clicknext.

5. 11. SelectEnglish andclickNext.
12. Confirmthe configurationandselectTrain.
13. Locate and openyourmodel. If youneedhelpfindingit,type yourname intothe searchbox.

6. 14. Reviewthe performanceof the model. SelectQuicktest.
15. Here we can testand validate ourmodel.Addthe followingtexttoclassify: The doctorsand
nursestookcare of me well duringmystay.

7. 16. ClickTestand reviewthe classification. Close the testdialog.
17. Nowyou can testany text. Testthe following: The weatherinAtlantaisgreat!
Close the testdialog.
18. Publishyourmodel.

8. Exercise 2- Use the model from Microsoft Flow
Once the model hasbeentrainedyoucan use the model fromMicrosoftFlow. Thisallowsyouto
leverage textclassificationinthe automationyoubuild. Inthisexercise,we will focusonhow touse the
Predictactionto analyze textandthentake actionbasedon the results.
Task 1 -Create a flow
1. Navigate tohttps://flow.microsoft.com ;signinif necessary.
2. Confirmthe environmentinthe upperrightcorneristhe one you have beenassignedforthe

3. SelectMy Flowsinthe leftnavigation.
4. Clickon Import.

9. 5. Uploadthe .zipfile namesProcessFeedback_Flow.zipthathasbeenprovided forthisworkshop.
6. Once the package detailsare displayed,clickonthe tool iconnexttothe CommonData Service

12. Once done clickon Import.

14. 13. Once completedthe import,Openthe Flow.
Task 2 – Invoke Predict and Parse the output
1. Expandthe Predictactionand on the Model dropdown locate andselectyourmodel youbuiltin
the previousexercise.

15. 2. The RequestPayloadwaspre-configuredand shouldlooklike the following. Whatyouare
doinghere isprovidingthe inputtothe Predictactionandconnectingitto the textyouwill input
whenthe flowisrun.
3. Next,because the Predictactioncanworkwithdifferenttypesof models,the outputcan
containdifferentdata. So future stepscaneasilyuse the output.We are goingto use a Parse
JSON actionthat will parse the outputandmake it available tosubsequentstepswithknown
names.
4. Click+ NewStepand type Parse JSON inthe search field.
5. Selectthe Parse JSON action.

16. 6. Clickinthe Contentfieldand selectResponse Payloadfromthe Dynamiccontentpanel.
7. Nextclickinthe Schemafieldandpaste inthe following. Thisisa schemathat tellsthe parse
actionwhat to expectinthe content. Youwill be able tofindthisinthe docs site inthe future.
