#5. Knowledge Management Systems (KMS)

Perhaps you often wonder about the meaning of Knowledge Management Systems (KMS). Essentially, they are a category of various available different types of information systems created to oversee and disperse the knowledge and expertise of an organization. KMS aims to aid in the development, preservation, sharing, and utilization of knowledge and information to enhance an organization’s decision-making abilities.

KMS is a subset of Management Information Systems (MIS) focusing on capturing and sharing organizational knowledge. They use technologies such as databases, knowledge bases, expert systems, and decision support systems to manage knowledge and information.

KMS has three types: enterprise-wide KMS, knowledge work systems, and intelligent techniques. Enterprise-wide KMS manage knowledge across the organization, while knowledge work systems support knowledge-intensive processes. Intelligent methods involve using artificial intelligence (AI) and machine learning (ML) algorithms to automate knowledge management processes.

#6. Expert Systems (ES)

This type of information system uses artificial intelligence (AI) to replicate the decision-making ability of a human expert. Expert Systems (ES) typically have a knowledge base containing a set of rules, algorithms, and heuristics used to reason about a specific domain.

Expert systems can analyze complex data sets, make inferences based on that data, and provide recommendations or solutions to problems. They are useful in fields where human expertise is critical, such as healthcare, finance, and engineering.

An example of an expert system is the MYCIN system, which emerged in the 1970s to help diagnose bacterial infections. MYCIN used a set of rules based on expert knowledge to determine the most likely bacterial cause of the infection and recommend a treatment plan.

Expert systems are effective in specific contexts, but the availability and accuracy of the knowledge base limit their usefulness. In addition, they are expensive to develop and maintain. Despite these limitations, expert systems are critical in various industries to improve decision-making and automate complex tasks.
