Topic: Background disambiguation


  
  Background - Wikipedia, the free encyclopedia
Background, in journalism, is an understanding between a news source and a reporter on the privacy of a discussion.
Background radiation refers to the natural radiation that is always present in a location.
Cosmic microwave background radiation is a natural constant radiation emanating throughout the universe.

 Cosmic microwave background radiation - Biocrawler   (Site not responding. Last check: 2007-10-01)
The cosmic microwave background radiation (CMB) is a form of electromagnetic radiation that fills the whole of the universe.
The period after the emission of the CMB and the observation of the first stars is semi-humorously referred to by cosmologists as the dark age, and is a period which is under intense study by astronomers.
Of these experiments, the Cosmic Background Explorer (COBE) satellite that was flown in 1989-1996 is probably the most famous and which made the first detection of the large scale anisotropies (other than the dipole).

Disambiguation is apt: at a time when "ecstatic jazz" has become a marketing label for empty bluster, this quartet's concentration on precise quarter-tones produces a new, if sombre, light.
The verb "disambiguate" is defined in Merriam Webster's Collegiate Dictionary as follows: "to establish a single semantic or grammatical interpretation for." If applied to this disk, then, the title suggests that Pandelis Karayorgis is attempting to define his music in a single interpretation.
Disambiguation is far too complex and far too worthy a disk to confine to one interpretation.

 Sky Background -- Recommendations and Resources   (Site not responding. Last check: 2007-10-01)
A background frame is often the first exposure in an astronomical observation with a CCD: the frame will then be subtracted from the actual observation result, leaving in theory only the incoming light from the astronomical object being observed.
The galactic X-ray background is produced largely by emission from hot gas in the Local Bubble within 100 parsecs of the Sun.
Background independence is a condition in theoretical physics, especially in quantum gravity, that requires the defining equations of a theory to be independent of the actual shape of the spacetime and the value of various fields within the spacetime.

 Syntax Definition for Language Prototyping: Introduction
Although disambiguation filters give an abstract account of disambiguation, implementation of disambiguation by means of a filter applied to the parse forest after parsing can be too inefficient for a number of disambiguation methods.
Disambiguation by means of priorities is implemented in the parser generator.
It was presented under the title using filters for the disambiguation of context-free grammars at the ASMICS Workshop on Parsing Theory in Milan and appeared in the proceedings.

 Word Sense Disambiguation: Timeline
For competing senses, the one with the highest relatedness score is the disambiguated sense.
In the word-sense disambiguation research area, there is the additional problem of manual tagging of word senses which is expensive.
After training, disambiguation results over a certain threshhold are treated as handtagged, and used as further evidence for the disambiguation of the word in question.

 Contextual weighting for Support Vector Machines in literature mining: an application to gene versus protein name ...
In this paper, we consider the disambiguation of the sense "gene" or "protein" when the name is not disambiguated explicitly by the author with the word "gene" or "protein" (e.g.
For each distance from the name to be disambiguated, we estimated the conditional probability that there is a word in the context at that distance and the word is another ambiguous name with the same sense, as well as the conditional probability that the word is a name with the opposite sense.
These probabilities are illustrated in Figure 1, where the solid line denotes the probability of an occurrence of a name with the same sense and the dashed line denotes the probability of the opposite sense.

 Word sense disambiguation patent invention
Systems and methods for word sense disambiguation, including discerning one or more senses or occurrences, distinguishing between senses or occurrences, and determining a meaning for a sense or occurrence of a subject term.
In order to achieve commercially acceptable performance, some means must be found to reliably discern the presence of a word sense, reliably distinguish between different senses of the same term, and reliably determine the correct sense for the terms that are encountered.
Such discerning, distinguishing, or determining of the sense of terms in written or spoken language is referred to, generally, as word sense disambiguation (WSD).

P-Progol is applied to a natural language processing task of learning rules for PP-attachment disambiguation (Kazakov et al.).
The background predicates map word-forms into lexical entries, and semantic classes, e.g.
Progol rules covering each of the classes are learned and then applied to associate semantic classes with a test example of a given class, therefore reducing semantic ambiguity in the phrase.

 Until recently, most NLP research has been focused on the understanding of a larger text
The methods used for word-sense disambiguation on a larger text cannot successfully be applied to such a domain.
the word plant is disambiguated to refer to a factory by the surrounding words (corporation, business, expenses, manufacturing, factory, etc.) which all point to the current domain of a manufacturing plant.
The same techniques used here to allow disambiguation to be applied to small collocations of words should also be more broadly applicable to other areas of word sense disambiguation where the current methods fail due to a lack of domain-dependence exhibited by the target word.

The parser should moreover enable the user option of basing the disambiguation of unclear cases on clear cases with the same content words from the text at hand; this may be particularly relevant for domain-restricted input text.
Another option is to invoke manual disambiguation mode requiring the user to manually disambiguate cohorts (alternative readings of a word form) of unresolved ambiguities after context-sensitive disambiguation.
Heuristic disambiguation constraints are a feature in CG enabling a regimented use of "riskier" constraint.

 Word-Sense Disambiguation
The knowledge-based method disambiguates nouns by matching context with information from a prescribed knowledge source.
WordNet is used because it combines the characteristics of both a dictionary and a structured semantic network, providing definitions for the different senses of the English words and defining groups of synonymous words by means of synsets, which represent distinct lexical concepts.
In the following section a summary of the background of word sense disambiguation is presented.

Compared to the previous study, a much richer, more linguistically motivated, background knowledge has been supplied in this task, consistmg of examples of noun phrases, verb chains, auxiliary verbs, and sets of part of speech categories.
The aim has been to create the background knowledge rapidly, without laborious hand-coding of linguistic knowledge.
In addition to the new background knowledge, new, more expressive rule types have been induced for two part of speech categories and compared to the corresponding rules of the previous bottom-Iine experiment.

These words may be located near to the name to be disambiguated, being strong indicators of its sense.
Note also that memorizing the names does not help the classifier to disambiguate names that do not exist in training data, for example, names introduced only recently.
However, the distances of the words with respect to the word to be disambiguated seem intuitively to be important.

"On background" and "not for attribution" mean reporters may quote sources but identify them only vaguely, such as a Pentagon official.
"Deep background" means reporters can use the information, but with no attribution.
Such a strategy would not affect investigative stories where individual reporters deal with sources who really have something to say, but for good reason don't want their names next to the information.
