In computational linguistics, word-sense disambiguation (WSD) is an open problem of natural language processing and ontology. WSD is identifying which sense of a word (i.e. meaning) is used in a sentence, when the word has multiple meanings. The solution to this problem impacts other computer-related writing, such as discourse, improving relevance of search engines, anaphora resolution, coherence, inference et cetera.
The human brain is quite proficient at word-sense disambiguation. The fact that natural language is formed in a way that requires so much of it is a reflection of that neurologic reality. In other words, human language developed in a way that reflects (and also has helped to shape) the innate ability provided by the brain's neural networks. In computer science and the information technology that it enables, it has been a long-term challenge to develop the ability in computers to do natural language processing and machine learning.
To date, a rich variety of techniques have been researched, from dictionary-based methods that use the knowledge encoded in lexical resources, to supervised machine learning methods in which a classifier is trained for each distinct word on a corpus of manually sense-annotated examples, to completely unsupervised methods that cluster occurrences of words, thereby inducing word senses. Among these, supervised learning approaches have been the most successful algorithms to date.
Creative Commons (CC) is a non-profit organization devoted to expanding the range of creative works available for others to build upon legally and to share. The organization has released several copyright-licenses known as Creative Commons licenses free of charge to the public. These licenses allow creators to communicate which rights they reserve, and which rights they waive for the benefit of recipients or other creators. An easy-to-understand one-page explanation of rights, with associated visual symbols, explains the specifics of each Creative Commons license. Creative Commons licenses do not replace copyright, but are based upon it. They replace individual negotiations for specific rights between copyright owner (licensor) and licensee, which are necessary under an "all rights reserved" copyright management, with a "some rights reserved" management employing standardized licenses for re-use cases where no commercial compensation is sought by the copyright owner. The result is an agile, low-overhead and low-cost copyright-management regime, profiting both copyright owners and licensees. Wikipedia uses one of these licenses.
The green hands aim at a target at the top of the screen, while avoiding the black obstacles. The actual state of the system is uncertain, and the eye provides local disambiguation of the "real" state. I also model visual inhibition during saccades - the disambiguation is inversely proportional to the eye's velocity, so the eye provides no useful information when it is in fast motion. The system is formulated as a stochastic optimal control problem, solved using differential dynamic programming over an augmented state space (representing the distribution in the real state space as a single Gaussian, estimated using the Kalman filter).

The Cessna 152 is an American two-seat, fixed tricycle gear, general aviation airplane, used primarily for flight training and personal use. It was based on the earlier Cessna 150, including a number of minor design changes and a slightly more powerful engine running on 100LL aviation gasoline. This video is targeted to blind users.

Deterrence theory gained increased prominence as a military strategy during the Cold War with regard to the use of nuclear weapons. It took on a unique connotation during this time as an inferior nuclear force, by virtue of its extreme destructive power, could deter a more powerful adversary, provided that this force could be protected against destruction by a surprise attack. Deterrence is a strategy intended to dissuade an adversary from taking an action not yet started, or to prevent them from doing something that another state desires. A credible nuclear deterrent, Bernard Brodie wrote in 1959, must be always at the ready, yet never used. In Thomas Schelling's classic work on deterrence, the concept that military strategy can no longer be defined as the science of military victory is p...
Lateral earth pressure is the pressure that soil exerts in the horizontal direction.The lateral earth pressure is important because it affects the consolidation behavior and strength of the soil and because it is considered in the design of geotechnical engineering structures such as retaining walls, basements, tunnels, deep foundations and braced excavations.The coefficient of lateral earth pressure, K, is defined as the ratio of the horizontal effective stress, σ’h, to the vertical effective stress, σ’v.The effective stress is the intergranular stress calculated by subtracting the pore pressure from the total stress as described in soil mechanics. ---Image-Copyright-and-Permission--- About the author(s): Ingolfson at English Wikipedia (Original text: Uploader.)

what are Fundamental Forces in Nature & Conservation Laws? Links: https://en.wikipedia.org/wiki/Fundamental_interaction his article is about conservation in physics. For the legal aspects of environmental conservation, see Environmental law and Conservation movement. For other uses, see Conservation (disambiguation). In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves over time. Exact conservation laws include conservation of energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric charge. There are also many approximate conservation laws, which apply to such quantities as mass, parity, lepton number, baryon number, strangeness, hypercharge, etc. Th...
Enterprises are facing a period of continuos transformation with an unprecedented pace. They have to become more efficient while fostering innovation. In this scenario IT technologies and solutions are the enablers of such transformation, bringing in a new computing model to support both current and a new class of application aimed to implement advanced cognitive models. In this video Massimo Leoni, IBM Distinguished Engineer, introduces you to the IBM Smarter Computing, a new computing model which is supporting such enterprises' transformation. Massimo explains the underlining forces that are at the base of this evolution describing how those new requirements are then translated in IBM solutions and technologies.
