Symbolab
Symbolab is an answer engine that provides step-by-step solutions to mathematical problems in a range of subjects. It was originally developed by Israeli start-up company EqsQuest Ltd., under whom it was released for public use in 2011. In 2020, the company was acquired by American educational technology website Course Hero. History In late 2011, Symbolab was released as a mathematical semantic search engine by Israeli entrepreneurs Michal Avny (CEO), Adam Arnon (Chief Scientist), and Lev Alyshayev (CTO). At the onset, it could interpret a user-entered equation or symbolic problem and find the solution if it existed. Later, the ability to show all of the steps explaining the calculation were added. The company's emphasis gradually drifted towards focusing on providing step-by-step solutions for mathematical problems at the secondary and post-secondary levels. Symbolab relies on machine learning algorithms for both the search and solution aspects of the engine. Acquisition in ... [...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), which is concerned with building systems that automatically answer questions 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 local 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 deal with a wide range of question types including: fact, list, definition, ''Ho ...

Semantic Search
Semantic search denotes search with meaning, as distinguished from lexical search where the search engine looks for literal matches of the query words or variants of them, without understanding the overall meaning of the query. Semantic search seeks to improve search accuracy by understanding the searcher's intent and the contextual meaning of terms as they appear in the searchable dataspace, whether on the Web or within a closed system, to generate more relevant results. Content that ranks well in semantic search is well-written in a natural voice, focuses on the user's intent, and considers related topics that the user may look for in the future. Some authors regard semantic search as a set of techniques for retrieving knowledge from richly structured data sources like ontologies and XML as found on the Semantic Web. Such technologies enable the formal articulation of domain knowledge at a high level of expressiveness and could enable the user to specify their intent in more d ...

Machine Learning
Machine learning (ML) is a field of inquiry devoted to understanding and building methods that 'learn', that is, methods that leverage data to improve performance on some set of tasks. It is seen as a part of artificial intelligence. Machine learning algorithms build a model based on sample data, known as training data, in order to make predictions or decisions without being explicitly programmed to do so. Machine learning algorithms are used in a wide variety of applications, such as in medicine, email filtering, speech recognition, agriculture, and computer vision, where it is difficult or unfeasible to develop conventional algorithms to perform the needed tasks.Hu, J.; Niu, H.; Carrasco, J.; Lennox, B.; Arvin, F.,Voronoi-Based Multi-Robot Autonomous Exploration in Unknown Environments via Deep Reinforcement Learning IEEE Transactions on Vehicular Technology, 2020.

Silicon Wadi
Silicon Wadi ( he, סִילִיקוֹן וְאֵדֵי, ) is a region in Israel that serves as one of the global centres for advanced technology. It spans the Israeli coastal plain, and is cited as among the reasons why the country has become known as the world's "start-up nation" (see science and technology in Israel). The highest concentrations of high-tech industry in the region can be found around Tel Aviv, including small clusters around the cities of Raʽanana, Petah Tikva, Herzliya, Netanya, Rehovot, and Ness Ziona. Additional clusters of high-tech industry can be found in Haifa and Caesarea. More recent high-tech establishments have been raised in cities such as Jerusalem and Beersheba, in towns such as Yokneam Illit, and in Airport City. Etymology The term "Silicon Wadi" is a pun-name derived from a similarly high-tech region in the United States known as Silicon Valley, which is located in California.

Science And Technology In The United States
Science and technology in the United States has a long history, producing many important figures and developments in the field. The United States of America came into being around the Age of Enlightenment (1685 to 1815), an era in Western philosophy in which writers and thinkers, rejecting the perceived superstitions of the past, instead chose to emphasize the intellectual, scientific and cultural life, centered upon the 18th century, in which reason was advocated as the primary source for legitimacy and authority. Enlightenment philosophers envisioned a "republic of science," where ideas would be exchanged freely and useful knowledge would improve the lot of all citizens. The United States Constitution itself reflects the desire to encourage scientific creativity. It gives the United States Congress the power "to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discov ...
