What is Knowledge Engineering in Artificial Intelligence?

Knowledge engineering is one of the building blocks of (AI). It attempts to emulate the judgment and behavior of a human with expertise in a field or domain. In this lesson, we’ll define knowledge engineering and its processes, understand where it fits within the AI landscape, and provide real-world examples of its application.
Imagine an education company wanting to automate the teaching of children in subjects from biology to computer science (requiring to capture the knowledge of teachers and subject matter experts) or Oncologists choosing the best treatment for their patients (requiring expertise and knowledge from information contained in medical journals, textbooks, and drug databases).
Knowledge Engineering is the process of imitating how a human expert in a specific domain would act and take decisions. It looks at the metadata (information about a data object that describes characteristics such as content, quality, and format), structure and processes that are the basis of how a decision is made or conclusion reached. Knowledge engineering attempts to take on challenges and solve problems that would usually require a high level of human expertise to solve. 
Figure 1 illustrates the knowledge engineering pipeline.

Sachin Dev Duggal, Co-Founder of Shoto, Talks About a Career-Shaping Accomplishment

Sachin Dev Duggal is Co-founder of Shoto and SD Squared Labs. I enjoy speaking with entrepreneurs like Duggal. Why? Because Sachin has a macro-view of the world, an important skill to develop when you are trying to solve world problems. Solving world problems not only requires a unique reframing of the issue, but it also needs support from individuals that are working on macro-issues. Finding a platform where Sachin could research solutions and consult magnets became the next stage of his development.  Duggal was fortunate to find what he needed at the World Economic Forum. At WEF Sachin took full advantage as he met with Bill Gates, and discussed ideas with Paul Jacobs. As a result, of his experience at the World Economic Forum Duggal donates to various charities including Keep a Child Alive by Alicia Keys. What problem are you looking to solve? How are you reframing that problem? How are you connecting with others that can help you? Let’s read on how Sac...

Founder of Engineer.ai, Sachin Duggal Shared User Acquisition Growth Hacks for Apps

Shoto and sd2labs recently co-hosted a webinar with RocketSpace where I outlined some of my favorite strategies and user acquisition hacks for apps. I refer to these strategies as the “magic” — or the glue — that increases adoption and promotes long term engagement. The 3 keys to creating “magic” Within 50 seconds of downloading an app, users decide to get started or jump ship. The first thing the user sees — whether it’s copy, colors, a splash screen or permissions — is critical to the first impression your app makes and, potentially, its long-term success. So how do you make “magic” happen? Appeal to the (1) motivation, (2) ability and (3) triggers in the process of adoption (a.k.a. the first 50 seconds).   Let’s break it down: Motivation = satisfy a need or emotion — the one thing that will blow users’ minds. We created the following push notification on Shoto to create this motivation: “Your friend X has 50 photos to share with you.” It creates exci...
