Building Intelligence: How Oracle Built a Digital Assistant January 26th US & January 28th EMEA & February 2nd 2021
This session focuses on the real-world experience of building, training, and testing the natural language processing (NLP) models for an AI-driven digital assistant. You’ll be introduced to Artie, a digital assistant that helps Oracle developers build chatbots. Using natural language, users can ask Artie varied questions to guide their learning. To build Artie, the development team had to determine the best way to train the natural language understanding models to better understand the speaker. This session shares the good—and the bad—of building and training language intelligence in a conversational assistant.

These services add to the existing Oracle Cloud for government core services, which include File Storage service, usage reports, Resource Manager, Console Announcements, Terraform, Kubernetes, autoscaling, and Oracle Cloud Infrastructure Monitoring.


Define Multiple Entity Prompts And Prompt Sequences To Make Your Digital Assistant Appear Less Robotic And More Human by Frank Nimphius
While chatbots shouldn't pretend to be human, they shouldn't behave robotic either. A bot that has a single prompt for interacting with a human can only display that single prompt, which sounds like a broken record if the prompt needs to be displayed again. In Oracle Digital Assistant, there are two things you can do to make your chatbot appear more natural when prompting users. Both have to do with entities and the use of either the System.CommonResponse component or the System.ResolveEntities component to render the entity.
A reoccurring theme you find on Oracle TechExchange is model-driven conversations that use entities to prompts users for input and for holding and validating user provided input. Custom entities, and when used in composite bag entities then system entities too, expose properties developers can set.


Accessing The Current Range Start For Bag Items In A Composite Bag Entity by Frank Nimphius
About Page Ranging
Messenger behaves differently when it comes to the number of buttons or the selection of items that can be rendered. To remove limitations, you can configure the data items that are displayed simultaneously on composite bag entity items.
For the users to be able to browse all data values, you then use buttons exposed on the System.CommonResponse component or the System.ResolveEntities component. What happens when a user tabs on a button is that the component navigates to a next or previous page range.


How To Tell Which Value Or Synonym Actually Resolved An Entity by Frank Nimphius
The System.Intent component in Oracle Digital Assistant resolves intents and extracts entities from a user message. Entities can be extracted if the message contains the entity value or a synonym defined for it.
For example, when asking for a currency code for a country, the following user messages work if Germany, German, Portugal, Portuguese or UK were defined as synonyms
"What is the currency code for Germany"
"What is the German currency code"


The yet not so well known "headerText" property in System.CommonResponse component attachment types by Frank Nimphius
The attachment type is a useful feature of the System.CommonResponse component, especially when the messenger is rendering images as part of a conversation.
A feature I was looking for is the ability to add a title string or a header text. So far I helped myself by adding a text response before rendering the attachment response. Well, I've done that so far.
As of Oracle Digital Assistant 20.08, the attachment type supports the headerText property, which in combination with the footerText property can produce output as shown below.


Testing Your Apache FreeMarker Expressions Using The Online FreeMarker Template Tester by Frank Nimphius
In In this article I explain how you can use the Apache FreeMarker Online Tester to debug and test expressions in Oracle Digital Assistant
About Apache FreeMarker in Oracle Digital Assistant
Apache FreeMarker is the expression engine used in Oracle Digital Assistant dialog flows, entities and skill and digital assistant settings.
An Apache FreeMarker expression is defined using the ${ ... } construct or as directives like ... . You can read up on Apache FreeMarker expressions at


Adding Paging Control to Tables in Visual Builder by Shay Shmeltzer
Paging control was a common pattern for controlling the number of records shown on a page and for fetching another set of records. Today, with the richer functionality provided by browsers, you can get a better user experience with native scroll functionality and a "load more" approach. I blogged about it in a previous entry that shows how scrolling/fetching/pagination works in VB tables by default. This "load more on scroll" approach is what you see in your Twitter and Facebook feeds for example. Google's search page seems to be one of the last remaining sites to stick with the "next 10 records" approach. At Oracle our UI experts also instructed our Cloud Apps development teams to not use paging controls. But, if you insist on adding a pagination control to your tables, here is a quick demo showing how to achieve this.


Displaying Nested Arrays with Nested Tables in Visual Builder by Shay Shmeltzer
Hierarchical data is very common when working with databases, but showing such data can pose challenges when you want to show all the data on one page. In the past I showed how to show hierarchy using a tree component, in this blog I'm building on top of the concepts shown there to create a UI representations that shows a nested details table for each master record.
In the example we use a data set of departments and employees that belong to each one of them. We want to show a table of the employees below the details of each department. This is a common representation in "report" type of outputs.


Debugging PWA Apps on Android by Shay Shmeltzer
Visual Builder makes it very easy to create a deploy a mobile application using the Progressive Web Application (PWA) packaging on your device. But what happens if the app doesn't function properly when it is running on your device? How do you troubleshoot the issues? The quick demo shows how to use the Chrome tools to debug your app as it is running on your Android device.
Start by connecting your mobile device to your computer using a data USB cable. Make sure that your device is recognized by your computer and also make sure that USB Debugging is turned on on your mobile device. The way you enable USB debugging on a device depends on the specific device/os version - so google your specific device instructions.


Business Object Client Side Caching with Visual Builder by Shay Shmeltzer
If you are using Visual Builder's Business Objects (BO) as a source of data for your Visual Builder user interface, caching their content on the client side can help improve your app performance. The latest version of Visual Builder provides a simple declarative way to control caching settings for your BOs.
Caching Considerations
There are a couple of points to consider before you implement caching though:
If your data is frequently changing, you might not want to cache it on the client as the cached data might be out of date when the user access it. For example, we wouldn't suggest caching the current inventory for each product in your warehouse, as this will change with every new order placed.

Using Terraform to launch the WebLogic Marketplace Stack - Part 1 - Jan Leemans
Oracle WebLogic Server for Oracle Cloud Infrastructure (OCI) enables provisioning of WebLogic domains on OCI through the use of a "stack", automating the setup of the various components required to run your Weblogic domain: network, load balancer, compute instances, or even a Kubernetes cluster. If you want to integrate the creation of a WebLogic domains as part of a larger automation on your Cloud Tenancy, you need to understand the principles of these Marketplace Stacks and how to access the corresponding images. In this article we explore the first of the three use-cases to automate the creation of WebLogic MarketPlace Stacks and you will learn how to spin up a WebLogic stack using terraform and the OCI Command Line.


Webinar: WebLogic and Application Modernisation - Sid Joshi, Jan Leemans, Joost Volker
Many organizations run their core business applications on WebLogic Server. In this webinar we will explore possible pathways to modernize and extend these applications using modern Cloud Native services. You will discover the various options of running WebLogic in a Cloud Model, how to develop hybrid architectures combining on-premise and Cloud deployments, and how to rapidly extend WebLogic applications with Microservices. This offers great opportunities for Oracle partners to deliver new WebLogic based applications, migrate existing WebLogic customers to the Cloud or modernize your managed services improving efficiency and decreasing cost. Secondly WL modernization has proven to open up new conversations for further PaaS modernization.
