Systems based on automatically learning the rules can be made more accurate simply by supplying more input data. However, systems based on hand-written rules can only be made more accurate by increasing the complexity of the rules, which is a much more difficult task. In particular, there is a limit to the complexity of systems based on hand-crafted rules, beyond which the systems become more and more unmanageable. However, creating more data to input to machine-learning systems simply requires a corresponding increase in the number of man-hours worked, generally without significant increases in the complexity of the annotation process.
In this lecture you will have the opportunity to experience being hypnotised through having your attention guided and focused conversationally. This lecture is best listened to a couple of times at least so that you can experience what it is like to go into hypnosis by having your attention guided and focused conversationally, and listen trying not to go into hypnosis so that you can observe and learn from what I am doing.
(see also: Stochastic grammar) Determine the parse tree (grammatical analysis) of a given sentence. The grammar for natural languages is ambiguous and typical sentences have multiple possible analyses. In fact, perhaps surprisingly, for a typical sentence there may be thousands of potential parses (most of which will seem completely nonsensical to a human). There are two primary types of parsing, Dependency Parsing and Constituency Parsing. Dependency Parsing focuses on the relationships between words in a sentence (marking things like Primary Objects and predicates), whereas Constituency Parsing focuses on building out the Parse Tree using a Probabilistic Context-Free Grammar (PCFG).
Well trained Neuro-Linguistic Programmers will always teach by installation, not by teaching technique after technique. Techniques out date themselves too quickly to base the field of NLP on a set of techniques. It is based upon the attitude, the models and the skills which allow for constant generation of new techniques which are more effective and work faster.
The American Psychological Association published a study comparing the effects of hypnosis, ordinary suggestion, and placebo in reducing pain. The study found that highly suggestible individuals experienced a greater reduction in pain from hypnosis compared with placebo, whereas less suggestible subjects experienced no pain reduction from hypnosis when compared with placebo. Ordinary non-hypnotic suggestion also caused reduction in pain compared to placebo, but was able to reduce pain in a wider range of subjects (both high and low suggestible) than hypnosis. The results showed that it is primarily the subject's responsiveness to suggestion, whether within the context of hypnosis or not, that is the main determinant of causing reduction in pain.[138]

Hypnosis is the induction of a deeply relaxed state, with increased suggestibility and suspension of critical faculties. Once in this state, sometimes called a hypnotic trance, patients are given therapeutic suggestions to encourage changes in behavior or relief of symptoms. For example, in a treatment to stop smoking, a hypnosis practitioner might suggest that the patient will no longer find smoking pleasurable or necessary. Hypnosis for a patient with arthritis might include a suggestion that the pain can be turned down like the volume of a radio.
In the 1980s and 1990s, a moral panic took place in the US fearing Satanic ritual abuse. As part of this, certain books such as The Devil's Disciples stated that some bands, particularly in the musical genre of heavy metal, brainwashed American teenagers with subliminal messages to lure them into the worship of the devil, sexual immorality, murder, and especially suicide.[156] The use of satanic iconography and rhetoric in this genre provokes the parents and society, and also advocate masculine power for an audience, especially on teenagers who were ambivalent of their identity. The counteraction on heavy metal in terms of satanic brainwashing is an evidence that linked to the automatic response theories of musical hypnotism.[157]
Therefore, Braid defined hypnotism as a state of mental concentration that often leads to a form of progressive relaxation, termed "nervous sleep". Later, in his The Physiology of Fascination (1855), Braid conceded that his original terminology was misleading, and argued that the term "hypnotism" or "nervous sleep" should be reserved for the minority (10%) of subjects who exhibit amnesia, substituting the term "monoideism", meaning concentration upon a single idea, as a description for the more alert state experienced by the others.[23]
