Knowledge Engine
A knowledge engine is part of a decision-support system that combines data with data models and inference rules to provide an interface for people who want to make decisions or discover related data. It may involve automatically extracting and structuring knowledge from less-structured sources, using these models and rules. History In the late 1990s, the Decision Support Group at the University of Fribourg developed a model for decision support software. This described the interface between data and models on one hand, and graphical interfaces for exploring them and making decisions on the other, as a knowledge engine. They also developed a mathematical modeling language, LPL, in concert with that work. With the rise of the semantic web, natural language processing, and topical knowledge bases, a number of other analytical tools have been categorized as knowledge engines, including in genomics (KnowEnG), modeling human action (PaStaNet), and speeding up general-purpose quest ...

Decision Support System
A decision support system (DSS) is an information system that supports business or organizational decision-making activities. DSSs serve the management, operations and planning levels of an organization (usually mid and higher management) and help people make decisions about problems that may be rapidly changing and not easily specified in advance—i.e., unstructured and semi-structured decision problems. Decision support systems can be either fully computerized or human-powered, or a combination of both. While academics have perceived DSS as a tool to support decision making processes, DSS users see DSS as a tool to facilitate organizational processes. Some authors have extended the definition of DSS to include any system that might support decision making and some DSS include a decision-making software component; Sprague (1980)Sprague, R;(1980).A Framework for the Development of Decision Support Systems" MIS Quarterly. Vol. 4, No. 4, pp. 1–25. defines a properly termed D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Fribourg
The University of Fribourg (; ) is a public university located in Fribourg, Switzerland. The roots of the university can be traced back to 1580, when the notable Jesuit Peter Canisius founded the Collège Saint-Michel in the City of Fribourg. In 1763, an academy of law was founded by the state of Fribourg which formed the nucleus of the present law faculty. The University of Fribourg was finally created in 1889 by an Act of the parliament of the Swiss Canton of Fribourg. The University of Fribourg is Switzerland's only bilingual university and offers full curricula in both French and German, two of Switzerland's national languages. Students number about 10,000; there are about 200 tenured professors and 700 other academic teaching and research personnel. The Misericorde Campus, constructed between 1939 and 1942, was designed by the architects Honegger and Dumas, students of Swiss architect Le Corbusier. There are five faculties: Catholic theology, law, natural sciences, hum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Question Answering
Question answering (QA) is a computer science discipline within the fields of information retrieval and natural language processing (NLP) that is concerned with building systems that automatically answer questions that are posed by humans in a natural language. Overview A question-answering implementation, usually a computer program, may construct its answers by querying a structured database of knowledge or information, usually a knowledge base. More commonly, question-answering systems can pull answers from an unstructured collection of natural language documents. Some examples of natural language document collections used for question answering systems include: * a collection of reference texts * internal organization documents and web pages * compiled newswire reports * a set of Wikipedia pages * a subset of World Wide Web pages Types of question answering Question-answering research attempts to develop ways of answering a wide range of question types, including fact, li ...

WolframAlpha
WolframAlpha ( ) is an answer engine developed by Wolfram Research. It is offered as an online service that answers factual queries by computing answers from externally sourced data. History Launch preparations for WolframAlpha began on May 15, 2009, at 7:00 pm CDT with a live broadcast on Justin.tv. The plan was to publicly launch the service a few hours later. However, there were issues due to extreme load. The service officially launched on May 18, 2009, receiving mixed reviews. The engine is based on Wolfram's earlier product Wolfram Mathematica, a technical computing platform. The coding is written in Wolfram Language, a general multi-paradigm programming language, and implemented in Mathematica. WolframAlpha gathers data from academic and commercial websites such as the CIA's ''The World Factbook'', the United States Geological Survey, a Cornell University Library publication called ''All About Birds'', '' Chambers Biographical Dictionary'', Dow Jones, the ''Cat ...

Knowledge Engineering
Knowledge engineering (KE) refers to all aspects involved in knowledge-based systems. Background Expert systems One of the first examples of an expert system was MYCIN, an application to perform medical diagnosis. In the MYCIN example, the domain experts were medical doctors and the knowledge represented was their expertise in diagnosis. Expert systems were first developed in artificial intelligence laboratories as an attempt to understand complex human decision making. Based on positive results from these initial prototypes, the technology was adopted by the US business community (and later worldwide) in the 1980s. The Stanford heuristic programming project led by Edward Feigenbaum was one of the leaders in defining and developing the first expert systems. History In the earliest days of expert systems, there was little or no formal process for the creation of the software. Researchers just sat down with domain experts and started programming, often developing the requi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knowledge Engineer
A knowledge engineer is a professional engaged in the science of building advanced logic into computer systems in order to try to simulate human decision-making and high-level cognitive tasks. A knowledge engineer supplies some or all of the "knowledge" that is eventually built into the technology. Overview Often, knowledge engineers are intermediaries employed to translate highly technical information which they elicit from domain experts into the actual computer program or data system . Knowledge engineers interpret and organize information on how to make systems decisions . The term "knowledge engineer" first appeared in the 1980s in the first wave of commercialization of AI – the purpose of the job is to work with a client who wants an expert system created for them or their business. Validation and verification Knowledge engineers are involved with validation and verification Verification and validation (also abbreviated as V&V) are independent procedures that ...
