Oracle Digital Assistant 20.12 introduces Unified Multi-lingual NLU, Enhanced Speech, and Data Manufacturing by Srini Vinnakota
I’m excited to announce that the Oracle Digital Assistant Platform Version 20.12 is now being rolled out across all our OCI data centers. Key updates include:
• Unified Multi-lingual NLU
• Enhanced Speech
• Data Manufacturing with Active Learning
Unified Multi-lingual NLU
20.12 represents a fundamental shift not only for the ODA Platform but for the Conversational AI space in general. With 20.12, we introduced a unified multi-lingual NLU model for key languages in Europe and Middle East. This means customers no longer have to build a separate digital assistant for each language nor do they have to rely on a translation service to power their Intent Classification and Entity Recognition. While multi-lingual language embeddings have become mainstream in the past couple of years, ODA is the first Conversational AI platform to introduce active cross-lingual usage with Few-Shot and Zero-Shot NLU training models for both intents and entities.

How to configure a bag item in a composite bag entity as optional by Frank Nimphius
Composite bag entities model real world objects like "order", "person", "car", "account" etc. Each attribute in such an object is referred to as a bag item. Bag items usually reference other entities (built-in or custom). The System.CommonResponse component and the System.ResolveEntities component can be used to generate dialogs at runtime for users to be prompted to provide input for each bag item.
A common use case for objects is that some of their attributes (bag items) are treated as optional. This means that the item will be prompted but the user can choose not to provide any information. In this article I explain by an example how you achieve the same behavior with composite bag entities.


The importance of test, measure & improvement in chatbots and NLP by Grant Ronald
Those of you of a certain age might recognize the above image - the TV test card: played whenever a channel was "off air" and used for calibration. Whilst this might represent an image of a time-gone-by, the concept of measuring against a known baseline is one we can all recognize and is particularly important for those of us developing chatbots/digital assistants.
At Oracle I run a team that whilst part of the development organization that build our conversation AI platform (Oracle Digital Assistant), we also build production chatbots using that platform (we are the team who eat the dog food!). And in one of our current projects we took the time to re-visit our initial language training data to see whether the lessons we've learned, and documented (below) had a measurable difference on the "intelligence" of our digital assistant.


Automating CI/CD for Oracle Cloud Functions with Visual Builder Studio by Shay Shmeltzer
Serverless computing is one of the more attractive aspects offered by cloud platform - letting you focus on coding functionality and letting the provider take care of providing dynamically scaling platform to run your code. Oracle is offering the Oracle Cloud Functions Service as a platform for hosting serverless functions. Oracle Functions is based on the Fn Project - an open source, container native solution for writing functions that supports a variety of languages (including Java, go, ruby, node, python, and more) . In this blog we'll highlight some of the capabilities that are built into Oracle Visual Builder Studio to help you manage the development cycle for such functions and to automate continuous deployment to the Oracle cloud platform.


Business Rules in Visual Builder Cloud Service by Ankur Jain
Business rules in Visual Builder Cloud Service (VBCS) allow to validate Business Objects data as well as to fire an event when data is inserted into the BO. There are five types of Business Rules that exist in VBCS:
• Object Triggers
• Field Triggers
• Object Validators
• Field Validators
• Object Functions


Filtering SingleSelect Values as You Type by Shay Shmeltzer
A customer has asked how they can achieve filtering of the results shown in a selectSingle component that is bound to a Service Data Provider (SDP) as they type values into the list. In this blog we'll show you how to get this behavior working.
A list that is based on an SDP doesn't hold a client side array of all the data - filtering will therefor be executed using a query sent to the server. The server returns the matching values to the client populating the SDP.
To indicate to an SDP that you want to send such filtering queries, you specify a new property to the SDP called transformsContext in your variable definition in your page's JSON.

Three ways to customise the WebLogic MarketPlace Stacks - Part 2 by Jan Leemans
Develop your own Stack to launch a WebLogic Pay-as-you-go Image
Oracle Marketplace offers a streamlined way to get started with a publisher's software, and through the Marketplace UI you can simply spin up any of these solutions through a simple wizard.
This blog is the second chapter in a series that will explore your options to work with Terraform and the Marketplace Stacks and Images of WebLogic as provided on the Marketplace, offering you the ability to spin up your own customised stacks using the "Pay-as-you-go" consumption of WebLogic licenses.
You will learn how to launch an individual Pay-as-you-go image with full control of the setup process, omitting the standard Stack provided on Marketplace.


Hands-on lab WebLogic for OCI (JRF) – Introduction
This lab will guide you through the steps to create a WebLogic for OCI Instance, more specifically using the Virtual Machine flavor, and using the JRF option (repository database required).
• If you are running this lab on a personal free tier account, you will need to do some initial setup in order to prepare your tenancy for this lab. These steps are described in the first chapter of this lab, called WebLogic for OCI as a VM - Prerequisites. You can obtain a free tier account via this link.
• The actual creation of the WLS instance is described in the second chapter of this lab, called WebLogic for OCI as a VM. Once the WLS instance is up and running, you can access the management console and deploy several test applications. In case you are running this lab on a shared instance, your instructor will provide you with the required information to be able to start this part immediately.

Excel generation example - Custom Java functionality on Oracle PaaS/JCS cloud by Jang-Vijay Singh
Introduction
In this example, I will describe a small Java utility that produces an Excel file. The Utility has a synchronous Rest API to act as an interface for callers.
Bear in mind that Oracle Integration Cloud has inbuilt capability to generate CSV files - CSV is a text-only format of comma/delimiter-separated values that can also be opened in a spreadsheet tool like Microsoft Excel or OpenOffice. However, Excel is a binary format capable of rich formatting, formulae, among other features.
The API that this post describes generates a proper well formatted Excel file, can be deployed in an Oracle PaaS environment on the Java Cloud Service (JCS),


Helidon 2.2.0 Released by Peter Nagy
The Helidon team is proud to announce that Helidon 2.2.0 is now available with the following new features and enhancements:
• MicroProfile GraphQL support
• Micronaut Integration
• Virtual Threads (Project Loom) support
• GraalVM Native Image support for MySQL JDBC driver
• Bug fixes and small improvements throughout
Helidon 2.2.0 is not a new major release so you don’t need to worry about API changes if you are running a prior 2.x version. If you are still using Helidon 1.x, consider upgrading to 2.x. Helidon 2.x has a lot of features that you shouldn’t miss such as GraalVM Native Image support in MicroProfile 3.3 applications!
What’s New in 2.2.0
MicroProfile GraphQL Support
Over the last few years developers and enterprises have adopted GraphQL at an astonishing rate. If you haven’t tried GraphQL yet, here are some reasons why you should


Helidon Messaging with Oracle AQ by Daniel Kec
Oracle Advanced Queueing (AQ) is the message queueing service used by the Oracle database. By providing PLSQL and JMS APIs in Advanced Queueing, Helidon is now uniquely positioned to interact with database events and benefit from Oracle database’s durability and high availability.
We are pleased to announce that Helidon 2.2.0, a first class citizen in the Oracle ecosystem, now comes with a specialized connector for reactive messaging.


Helidon, Logging, and MDC by Tomas Langer
Helidon is designed to have the smallest number of third party dependencies as possible. With that goal in mind, we originally decided to use Java Util Logging (JUL) as its an integral part of the JVM with no added dependencies.
In Helidon 2.2.0, however, we have decided to support the following logging frameworks and some of their features:
• Java Util Logging (JUL) — already supported and does not require any changes in Helidon
• Simple Logging Facade for Java (SLF4J) — an API that can be used to log into multiple logging implementations (logback, Log4j, JUL)


GraalVM quick reference by Oleg Šelajev
There are three main ways how GraalVM can help with the Java applications: making them faster by using the state-of-the-art JIT compiler, compiling them into standalone native executables with instant startup and low memory consumption, and enhancing them with libraries or code in other supported languages.
This quick reference is a one-page short summary of what GraalVM can do and the key options and commands to illustrate its capabilities. You can download it and print. It fits neatly on an A4 paper, so you can hang it in the office and use it as a reminder of what GraalVM can do and which options turn it on. Be sure to grab the pdf version for printing so it looks neat and sharp. Note that if your printer is more comfortable with the US letter paper formats please make sure to get this version, it’ll look better.


MicroProfile GraphQL Support Now Available in Helidon MP by Tim Middleton
We are pleased to announce that Helidon MP version 2.2.0 now supports the MicroProfile GraphQL specification from the Eclipse Foundation.
GraphQL is an open-source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data. GraphQL interprets strings from the client, and returns data in an understandable, predictable, pre-defined manner. GraphQL is an alternative, though not necessarily a replacement for REST.
GraphQL provides three types of data operations: query, mutation and subscription. The schema is the core of GraphQL and clearly defines the operations supported by the API, including input arguments and possible responses.
