Hands-on Microsoft Flow from Nakkeeran Natarajan

Using Azure Functions, Cognitive Services and Flow for classifying Office 365 SharePoint Word Documents - Part II

Let us look how to integrate Azure Function, Cognitive services into Microsoft Flow for extracting tags/categories and update the SharePoint document item.

This article series helps us to work on a special use case of extracting information of word documents uploaded to Office 365 SharePoint libraries and then analyze/classify the document content using Azure Cognitive Services. Then update the document with classified data as tags/categories. The article links are shown below.

• Using Azure Functions, Cognitive Services and Flow for classifying Office 365 SharePoint Word Documents - Part I (Previous Article) - Azure function is briefly explained with code to understand how the data is being extracted using open XML formats/references available.

Extract Code From Github

The Azure function created in the previous article is available on Github repository (https://github.com/nakkeerann/analyze-sp-word-documents).

• Clone the code from the github repository to the local. 
• Open in visual studio and make necessary changes, like updating user credentials and SharePoint site and details.

Using Azure Functions, Cognitive Services and Flow for classifying Office 365 SharePoint Word Documents - Part I

This article series helps us to work on a special use case of extracting information of word documents uploaded to Office 365 SharePoint libraries and then analyze the document content using Azure Cognitive Services.

We have seen before extracting tags and metadata properties of image files from Office 365 SharePoint using Microsoft Flow and Azure Cognitive Services.

Microsoft Flow has a Get File content action, but that doesn't help extracting word documents content. Only it supports extracting content of notepad as straight forward approach. Since Microsoft Flow doesnt provide any option to read the word documents content, we will be using Azure Functions to extract the content. Once we have the content, we will use Azure Cognitive service to get the tags for the content extracted. Here Microsoft Flow is used to manipulate triggers and subsequent actions. So our algorithm is will be as follows.
