The earliest work in computerized knowledge representation was focused on general problem solvers such as the General Problem Solver (GPS) system developed by Allen Newell and Herbert A. Simon in 1959. These systems featured data structures for planning and decomposition. The system would begin with a goal. It would then decompose that goal into sub-goals and then set out to construct strategies that could accomplish each subgoal. In these early days of AI, general search algorithms such as A* were also developed. However, the amorphous problem definitions for systems such as GPS meant that they worked only for very constrained toy domains (e.g. the "blocks world"). In order to tackle non-toy problems, AI researchers such as Ed Feigenbaum and Frederick Hayes-Roth realized that it was necessary to focus systems on more constrained problems. These efforts led to the cognitive revolution in psychology and to the phase of AI focused on knowledge representation that resulted in expert systems in the 1970s and 80s, production systems, frame languages, etc. Rather than general problem solvers, AI changed its focus to expert systems that could match human competence on a specific task, such as medical diagnosis. Expert systems gave us the terminology still in use today where AI systems are divided into a Knowledge Base with facts about the world and rules and an inference engine that applies the rules to the knowledge base in order to answer questions and solve problems. In these early systems the knowledge base tended to be a fairly flat structure, essentially assertions about the values of variables used by the rules.[2] In addition to expert systems, other researchers developed the concept of frame-based languages in the mid-1980s. A frame is similar to an object class: It is an abstract description of a category describing things in the world, problems, and potential solutions. Frames were originally used on systems geared toward human interaction, e.g. understanding natural language and the social settings in which various default expectations such as ordering food in a restaurant narrow the search space and allow the system to choose appropriate responses to dynamic situations. It was not long before the frame communities and the rule-based researchers realized that there was synergy between their approaches. Frames were good for representing the real world, described as classes, subclasses, slots (data values) with various constraints on possible values. Rules were good for representing and utilizing complex logic such as the process to make a medical diagnosis. Integrated systems were developed that combined Frames and Rules. One of the most powerful and well known was the 1983 Knowledge Engineering Environment (KEE) from Intellicorp. KEE had a complete rule engine with forward and backward chaining. It also had a complete frame based knowledge base with triggers, slots (data values), inheritance, and message passing. Although message passing originated in the object-oriented community rather than AI it was quickly embraced by AI researchers as well in environments such as KEE and in the operating systems for Lisp machines from Symbolics, Xerox, and Texas Instruments.[3] The integration of Frames, rules, and object-oriented programming was significantly driven by commercial ventures such as KEE and Symbolics spun off from various research projects. At the same time as this was occurring, there was another strain of research that was less commercially focused and was driven by mathematical logic and automated theorem proving. One of the most influential languages in this research was the KL-ONE language of the mid-'80s. KL-ONE was a frame language that had a rigorous semantics, formal definitions for concepts such as an Is-A relation.[4] KL-ONE and languages that were influenced by it such as Loom had an automated reasoning engine that was based on formal logic rather than on IF-THEN rules. This reasoner is called the classifier. A classifier can analyze a set of declarations and infer new assertions, for example, redefine a class to be a subclass or superclass of some other class that wasn't formally specified. In this way the classifier can function as an inference engine, deducing new facts from an existing knowledge base. The classifier can also provide consistency checking on a knowledge base (which in the case of KL-ONE languages is also referred to as an Ontology).[5] Another area of knowledge representation research was the problem of common sense reasoning. One of the first realizations learned from trying to make software that can function with human natural language was that humans regularly draw on an extensive foundation of knowledge about the real world that we simply take for granted but that is not at all obvious to an artificial agent. Basic principles of common sense physics, causality, intentions, etc. An example is the frame problem, that in an event driven logic there need to be axioms that state things maintain position from one moment to the next unless they are moved by some external force. In order to make a true artificial intelligence agent that can converse with humans using natural language and can process basic statements and questions about the world, it is essential to represent this kind of knowledge. One of the most ambitious programs to tackle this problem was Doug Lenat's Cyc project. Cyc established its own Frame language and had large numbers of analysts document various areas of common sense reasoning in that language. The knowledge recorded in Cyc included common sense models of time, causality, physics, intentions, and many others.[6] The starting point for knowledge representation is the knowledge representation hypothesis first formalized by Brian C. Smith in 1985:[7] Any mechanically embodied intelligent process will be comprised of structural ingredients that a) we as external observers naturally take to represent a propositional account of the knowledge that the overall process exhibits, and b) independent of such external semantic attribution, play a formal but causal and essential role in engendering the behavior that manifests that knowledge. Currently one of the most active areas of knowledge representation research are projects associated with the Semantic Web. The Semantic Web seeks to add a layer of semantics (meaning) on top of the current Internet. Rather than indexing web sites and pages via keywords, the Semantic Web creates large ontologies of concepts. Searching for a concept will be more effective than traditional text only searches. Frame languages and automatic classification play a big part in the vision for the future Semantic Web. The automatic classification gives developers technology to provide order on a constantly evolving network of knowledge. Defining ontologies that are static and incapable of evolving on the fly would be very limiting for Internet-based systems. The classifier technology provides the ability to deal with the dynamic environment of the Internet. Recent projects funded primarily by the Defense Advanced Research Projects Agency (DARPA) have integrated frame languages and classifiers with markup languages based on XML. The Resource Description Framework (RDF) provides the basic capability to define classes, subclasses, and properties of objects. The Web Ontology Language (OWL) provides additional levels of semantics and enables integration with classification engines.[8][9]

You may have heard of the concept of Industry 4.0 – if not this is otherwise known as the new age industrial revolution. It is a prediction that the manufacturing industry is set to replace workers with modern technology across many sectors. TRS, a supplier of manufacturing staffing services has researched and reviewed the current engineering climate – with its future. There has always been a demand for skilled employees within manufacturing jobs, however, many are finding difficulty in securing a skilled staff force in an increasingly productivity driven workplace. Industry 4.0 is predicted to see manufacturers across the globe move toward new business models with data, cyber systems and cloud computing at its foundations. With technological advancement expanding across all engineering roles, there is a growing skepticism about the future of the engineering work force. However, research suggests that employment levels could thrive as staff could work in conjunction with new technologies instead of being replaced by them. The US Manufacturing industry is predicted to have as many as 2.4 million jobs to fill between now and 2028. According to Operations Solutions, the lack of qualified talent in Manufacturing could be set to incur the collective loss of $454 billion in GDP by 2028. From a Manufacturing Recruitment Agency viewpoint, there are a variety of issues that are assisting this economic loss – which are generally surrounding the perceptions of the future of Manufacturing. The enhancement of technological advancements, according to Forbes, create misconceptions about the need for human staff in the near future. Workers have already been replaced by particular systems on the manufacturing line, with an ability to mimic repetitive processes at a faster and more accurate rate. This to many is a sign that traditional methods of production are being replaced by machinery. Although this appears a stressful concept, Forbes explain that this process has happened previously in history. “In the mid-19th century, the machines of the Industrial Revolution were replacing traditional farming methods and changing the face of agriculture. But rather than see human staff pushed out, this, in fact, led to the creation of new job roles and skills ― from machinery operators to vehicle drivers.” This future Industrial enhancement will in fact open up the possibility of new job role opportunities as previous industrial development has, whilst improving overall site safety. We can already see this new method of working within current production processes. WoodBusiness have explained that their open software solution “ActiveAssist” actually enhances employee experience, using Identification systems to load required plans that are then projected onto the work surface. Machinery guides the employee through the workflow whilst tracking movements through 3D cameras to ensure steps are automatically updated when required. The automotive sector is another example that employees at all levels – mechanical engineering positions to sales and senior executives have the ability to collaborate with technology and have a more rewarding experience. According to Manufacturing.net, “Alfred P. Sloan Jr.’s commitment to new concepts such as automotive styling and Henry Ford’s introduction of the assembly line – defines an industry in which change occurs more often than not.” The latest enhancement is said to be delivered by Industry 4.0, with the increasing demand for automation. This leads the way for more refined customer insight, as well as an increase in production therefore reducing the workload. Current automotive staffing increasingly offers more time to focus and use creative thinking. Machines being used to benefit staff can also be applied in the concept of the demand and supply issue of skilled employees. Deloitte and The Manufacturing Institute recently submitted their fourth skills gap study with reference to the future of manufacturing work. The study explains that “As recently as August 2018, there were 508,000 open jobs in US manufacturing... While the job gains are positive indications that the industry continues to recover from the Recession and reflect strong production levels, it also means that finding talent with the right skills to fill the open jobs could reach crisis proportions.” Results show that maintaining production levels to satisfy customer demand is one of the biggest challenges arising in the next three years according to business executives. This is directly correlated with the difficulty in finding skilled workers who can complete their job accurately. “Many manufacturers today are turning toward automation to supplement the low-skilled jobs they cannot fill and instead focus their existing workers on jobs that are either higher skilled or require uniquely human skills.” One of the top skills predicted to be in significant demand is the concept of critical thinking. As the manufacturing process becomes increasingly automated, human skills such as this will be valued across Manufacturing. The insecurity associated with Industry 4.0 will be short lived. As technology and automation evolves throughout Manufacturing we are seeing a change in how staff perform - not replacing staff, a development in their roles, and a demand for typically human skills on the rise. A human-machine pairing could offer an opportunity to close the skills gap and invent new roles available for workers that will deliver value.
