Knowledge engineers integrate structured knowledge into computer systems (knowledge bases) in order to solve complex problems normally requiring a high level of human expertise or artificial intelligence methods. They are also responsible for eliciting or extracting knowledge from information sources, maintaining this knowledge, and making it available to the organisation or users. To achieve this, they are aware of knowledge representation and maintenance techniques (rules, frames, semantic nets, ontologies) and use knowledge extraction techniques and tools. They can design and build expert or artificial intelligence systems that use this knowledge.

Tasks

In such cases tasks would include -
(a) Developing plans to safeguard computer files against accidental or unauthorized modification, destruction or disclosure and to meet emergency data processing needs;
(b) Training users and promoting security awareness to ensure system security and to improve server and network efficiency;
(c) Conferring with users to discuss issues such as computer data access needs, security violations, and programming changes;
(d) Monitoring current reports of computer viruses to determine when to update virus protection systems;
(e) Modifying computer security files to incorporate new software, correct errors or change individual access status;
(f) Monitoring use of data files and regulate access to safeguard information in computer files;
(g) Performing risk assessments and executing tests of data processing system to ensure functioning of data processing activities and security measures;
(h) Encrypting data transmissions and erecting firewalls to conceal confidential information as it is being transmitted and to keep out tainted digital transfers.
