Knowledge engineering can be treated like a project. In some respects, the creation of a knowledge base is a one-time collection of activities that pursue a specific end in the creation of a knowledge base. This work will take considerable time and resources. Planning and management should be part of the process. This post covers some... Continue Reading →
Creating an expert system's knowledge base is the heart of knowledge engineering. This description covers the first 3 steps of the process at a high level. Orientation Knowledge engineers require orientation to the processes and methodologies that will be used to create the knowledge base for the particular system under construction. Subject matter experts also... Continue Reading →
When I'm speaking at conferences about the expanded use of legal tech, a lawyer or judge in the audience will invariably show an eagerness to highlight the risks of these new tools. Legal expert systems are no exception. Alarmists will often dwell on the very existence of a risk, with little concern for the scale,... Continue Reading →
Logic can be a powerful tool for helping non-expert users cope with the complexity of the law. It can become a particularly powerful legal problem diagnosis tool. It's helpful to work through an example using a typical piece of legislation. Let's assume our user has a specific type of legal issue under the fictional Widgets Act.... Continue Reading →
It's easy to find articles and blog posts these predicting that intelligent technologies will take work away from lawyers at some point in the future. And maybe that will happen eventually, at least for some lawyers. But there are two reasons to be confident that intelligent tech like expert systems won't put lawyers out of work...

In terms of architecture and functions, expert systems and filing assistants are often indistinguishable. In these cases, it's easy to conclude they're the same. In areas like justice, the differences are insignificant. In the future, they'll vanish altogether. There may be differences around how we use these tools. Expert systems use expert knowledge to reason... Continue Reading →
Each rule in an expert system knowledge base follows a conditional logic approach to reasoning. If a condition is satisfied, then the system makes a deduction. The rules in an expert system's knowledge base can be connected or chained together. This chaining allows the system to make several deductions in sequence. To make this forward-chaining approach...

Is an expert system better than a human expert? Sometimes. An expert system can out-reason humans - especially non-expert humans - in a particular domain. If you have a good knowledge base designed to reason well, it won't fail. Depth If the knowledge base contains very deep knowledge resembling advanced expertise, the system will reason like...

Expert systems can reason. Well, sort of, anyway. They don't have brains and can't think for themselves. So humans have to program them to emulate or reproduce the outputs of human reasoning in a different way. The expert systems I work on reason through the application of rules. The rules make the system reason on the... Continue Reading →
Expert systems are technology-based tools that help to solve problems. Knowledge engineering is the process of capturing intelligence from human experts so that it can be used by the expert system for its reasoning. Human itelligence is put into an artificial machine to make the system an expert in a specific domain. Of course, this intelligent... Continue Reading →
