Train Watson Discovery using an exported model

If you want to use a free plan of Discovery, you'll need to build your own model. Follow this tutorial:

Although the above tutorial is intended to be a prerequisite for the code pattern, we have also saved an exported model that can be used if you have an Advanced Plan instance of Discovery. This is expected to be especially useful if you've done the tutorial already, but want a quicker way to reproduce the results.

Steps

  • You create a paid version of Watson Discovery which will enable you to import the model from the tutorial. This approach is faster, and you will not have to annotate the insurance document yourself. To do this approach, first ensure you have a Watson Discovery Advanced plan. This one requires a credit card.
    • Click here to find Discovery in the IBM Cloud catalog.
    • Select a region.
    • Select a pricing plan. Use the Advanced plan.
    • Set your Service name or use the generated one.
    • Click Create.
    • Once you create the service, and then click on the service from the cloud.ibm.com homepage, it should show Plan Advanced in the right hand side of the page, as shown below:

  • Next, click on Launch Watson Discovery and then create a collection and add in the data/discovery/sample-insurance.docx file from your cloned repo as shown below:

  • Once Watson is done processing the document, click on Configure data in the top-right corner of the screen, as shown below:

  • Next, click on Import model and select the insurance.sdumodel file from the data/discovery directory in your cloned repo as shown below.

  • Once the model is applied, you should see a green notification in the top-right corner of the screen.

Manage the fields in your document

  • Click on the Manage fields tab in the upper-left corner of your screen.

  • On the left-hand side of the page, under Identify fields to index, turn off the footer field.

  • Next, click on split document on each occurrence of, and select subtitle so that we split the document by subtitle.

  • Lastly, click on Apply changes to collection and add in the same sample-insurance.docx file you uploaded at first.

  • Once your upload is done, you will be taken to the overview page. Refresh your browser to see that Watson is working to split the documents. After Watson is done, we should have over 10 documents. This is because we have split the original document into multiple, smaller documents based on the subtitle. This makes retrieving the answer to a particular question a lot easier for Watson, and enables us to get more accurate enrichments as well, such as sentiment analysis.

Query Watson in natural language

  • One of the main benefits of Watson is its ability to answer questions from your document in natural language. Before we do this, let's configure Watson to answer us directly with the text it has analyzed from our insurance document.

  • Click on the magnifying glass icon in the sidebar on the left-hand side of the screen. Next click on more-options at the bottom of the screen.

  • Next, under Passages select No for Include relevant passages.

  • Next, under Documents for fields to return select text.

  • Lastly, for Number of documents to return select 3.

  • Scroll back up to the top of hte page, and under Search for documents make sure Use natural language is selected. Then ask Watson the following question: Does my insurance cover glass repairs?. Once the answer comes back in the top-right corner, Summary will be selected. Go ahead and click on JSON.

  • You should see that Watson will pull out the relevant text from the document that says the insurance company will pay for replacement or repair of the glass in your vehicle's windscreen, sunroof, or windows if the vehicle is lost or damaged.

  • Repeat the process for Does my coverage include medical expenses? and Does my insurance cover damage to my vehicle.
