	PH - Wikipedia, the free encyclopedia
		Though pH is generally expressed without units, it is not an arbitrary scale; the number arises from a definition based on the activity of hydrogen ions in the solution.
		The pH scale is a reverse logarithmic representation of relative hydrogen proton (H+) concentration.
		An indicator is used to measure the pH of a substance.

		Or in layman's terms, the " pH " value is an approximate number between 0 and 14 for the negative decimal log of the hydronium - ion concentration.
		Electronic pH meters consist of an electrolytic cell in which an electric current is created due to the hydrogen cations completing the circuit.

		The value is close enough, however, for neutral pH to be 7.00 to two significant figures, which is near enough for most people to assume that it is exactly 7.
		There is also pOH, in a sense the opposite of pH, which measures the concentration of OH ions.

		Though a pH value has no unit, it is not an arbitrary scale; the number arises from a definition based on the activity of hydrogen ions in the solution.
		The value is close enough, however, for neutral pH to be 7.00 to three significant figures, which is near enough for most people to assume it is exactly 7.

	Acid - Wikipedia, the free encyclopedia
		The pH of a solution is a measurement of the concentration of hydronium.
		Neutralization is the reaction between equal amounts of an acid and a base, producing a salt and water; for example, hydrochloric acid and sodium hydroxide form sodium chloride and water:
		Neutralization is the basis of titration, where a pH indicator shows equivalence point when the equivalent number of moles of a base have been added to an acid.

	PH - Enpsychlopedia
		In nonaqueous solutions or non-SATP conditions, the pH of neutrality may not even be close to 7.
		Most substances have a pH in the range 0 to 14, although highly acidic or basic substances may have a pH less than 0 or greater than 14.
		Used in conjunction with spectrophotometric methods to determine the relative abundance of each indicator species, extremely precise determinations can be made.

	Language in India
		Those who work in the area of machine translation (MT) and word sense disambiguation (WSD) expected that if meaning of words is possible to extract from LC, then many unwanted problems of MT and WSD will be dissolved without further difficulty.
		It builds up a cognitive interface between language and reality, by which we conceive: who says, what is said, to whom it is said, when it is said, where it is said, why it is said, and how it is said.
		Thus, GC becomes the most important and valuable source for sense disambiguation of words because it supplies necessary information to know if TW has any sense variation, and if so, what is that sense.

		For disambiguation, the normalizing factor Z(x) is the same for every parse of a given sentence and can be ignored.
		Because the size of the treebanks we have currently available is much too small to estimate these quantities accurately, we have chosen to do our estimation using unsupervised learning.
		We have parsed a large corpus (`de Volkskrant' newspaper text: first four months of 1997) using the penalty rules described in the previous section as our disambiguator.

	Dissertation Uta Schwertel (Site not responding. Last check: 2007-10-21)
		In this thesis I investigate problems of representing, disambiguating and reasoning with plurals from a computational perspective.
		Whereas many existing approaches to plural semantics work on a model-theoretic basis using higher-order representation languages I propose a proof-theoretic approach to plural semantics based on a flat first-order semantic representation language thus showing that a trade-off between expressive power and logical tractability can be found.
		The problem of automatic disambiguation of plurals is tackled by a deliberate decision to drastically reduce recourse to contextual knowledge for disambiguation but rely instead on structurally available and thus computationally manageable information.

		I have finished my Ph.D. Thesis with the title "Linguistic Knowledge and Word Sense Disambiguation" and have successfully defended it on November 1, 2004.
		Since there is very little disambiguated material available (without which evaluation of results is not possible), I circumvented this problem by artificially creating such data using pseudowords.
		I have especially been investigating whether disambiguating pseudowords is comparable to the task of disambiguating real ambiguous words and came to the conclusion that these two tasks are not substitutable.

		Using an automatic algorithm, we assign a grammatical template to each node of a lexical ontology.
		Benefits of this work potentially include the disambiguation of VerbOcean, the disambiguation of new conceptualizations, improved unsupervised word sense disambiguation, and the personalization of lexical ontologies, like WordNet, to a particular domain.
