  Sequence Disambiguation
More precisely, Levy (1996) proposed that sequence coding by the hippocampus may be especially important when the sequences have overlapping elements through which memory of earlier elements must be remembered to complete each distinct sequence, a process called sequence disambiguation.
However, it is not clear from this study whether the demand for disambiguation of sequences per se, rather than other aspects of spatial processing, is critical.
In order to test whether sequence disambiguation is a fundamental feature of memory processing dependent on the hippocampus, we designed a sequence disambiguation task after Levy's (1996) formal model that involved two series of events that overlap in the middle items.

  Britain.tv Wikipedia - Sequence
A subsequence of a given sequence is a sequence formed from the given sequence by deleting some of the elements without disturbing the relative positions of the remaining elements.
If the terms of the sequence are a subset of an ordered set, then a monotonically increasing sequence is one for which each term is greater than or equal to the term before it; if each term is strictly greater than the one preceding it, the sequence is called strictly monotonically increasing.
Sequences over a field may also be viewed as vectors in a vector space.

 DNA - Encyclopedia, History, Geography and Biography
DNA is a long polymer of nucleotides and encodes the sequence of the amino acid residues in proteins using the genetic code, a triplet code of nucleotides.
Within a gene, the sequence of nucleotides along a DNA strand defines a messenger RNA sequence which then defines a protein, that an organism is liable to manufacture or "express" at one or several points in its life using the information of the sequence.
The relationship between the nucleotide sequence and the amino-acid sequence of the protein is determined by simple cellular rules of translation, known collectively as the genetic code.

 Sequence (poetry) at AllExperts
One well-known sequence, falsely attributed to Notker during the Middle Ages, is the prose text Media vita in morte sumus ("In the midst of life we are in death"), which was translated by Cranmer and became a part of the burial service in the funeral rites of the Anglican Book of Common Prayer.
In the Missal of Pius V (1570) the number of sequences for the entire Roman Rite was reduced to four: Victimae paschali laudes (11th century) for Easter, Veni Sancte Spiritus for Pentecost(12th century), Lauda Sion Salvatorem (c.1264) for Corpus Christi, and Dies Irae (13th century)for All Souls and in Masses for the Dead.
Sequences from the middle period, starting around the 11th century, such as the sequence for the Mass of Easter Day, Victimae paschali laudes, are less likely to have single lines outside of couplets, and their couplets are more likely to rhyme.

Thus the entire nucleotide sequence of each strand is complementary to that of the other, and when separated, each may act as a template with which to replicate the other from free nucleotides (middle and lower half of the illustration at the right).
The DNA helix can assume one of three slightly different geometries, of which the "B" form described by James Watson and Francis Crick is believed to predominate in cells.
Segments of DNA that cells have methylated for regulatory purposes may adopt the Z geometry, in which the strands turn about the helical axis like a mirror image of the B form.

Most probabilistic disambiguation models therefore build directly on that work: they characterize the probabilities of sentence-analyses by means of a "stochastic grammar", constructed out of a competence grammar by augmenting the rules with application probabilities derived from a corpus.
Linguistic disambiguation involves classification under an ambiguous definition of the "case description language", i.e., the formal representation of the utterance analyses, which is usually a grammar.
The notion of a cover is then generalized to a sequence of connecting tiles: a sequence of connecting tiles is an ordered sequence of tiles such that every tile is connecting to the tile that precedes it in that sequence.

 1998 Conference Proceedings
The system is based on a process known as "word-level disambiguation," where the system compares a sequence of keystrokes to words in a large database to determine the intended word.
Prior research on the application of disambiguation to augmentative communication applications has focused on using the letter-by-letter approach, sometimes in combination with a word-level approach based on a small database of common words.
In the case of a system based on word-level disambiguation used by an individual with adequate literacy skills, the association between any desired word and the selection sequence required to generate it is based simply on the spelling of the word.

We attempt to semantically disambiguate these definitions and recognize a ``SQUARE'' regardless of the fact that it can be either the right-handed or a left-handed square.
The figure 4a shows that the semantic structure recovered was that of a right-hand square and the whole sequence was labeled as a ``SQUARE''.
Recognition results for a left-handed square sequence are shown in figure 4b.

An alternative to the word frequency approach is to calculate the probability of a given sequence of tags occurring.
Next, we face the problem of determining transitional probabilities for sequences of words, which boils down to calculating the number of times that the event occurs given the occurrence of another event.
The final step in the basic probabilistic disambiguation process is to use the transitional probabilities just computed to determine the optimal path through the search space ranging from one unambiguous tag to the next.

 MULTI-PARAGRAPH SEGMENTATION OF EXPOSITORY TEXT
For example, disambiguation algorithms that train on arbitrary-size text windows, e.g., yarowsky92 and gale92c, and algorithms that use lexical co-occurrence to determine semantic relatedness, e.g., schuetze93, might benefit from using windows with motivated boundaries instead.
Although many aspects of discourse analysis require such a model, I choose to cast expository text into a linear sequence of segments, both for computational simplicity and because such a structure is sufficient for the coarse-grained tasks of interest here.
From a computational viewpoint, deducing textual topic structure from lexical connectivity alone is appealing, both because it is easy to compute, and also because discourse cues are sometimes misleading with respect to the topic structure [Brown and Yule1983](§3).

 Pattern Summary
For example, the sequence {3, -6, 12, -24} is geometric because it has a common ratio of -2.
For example, the sequence {1, -1, 1, -1} can be identified as geometric because there is a common ratio of -1; hence, the next term is 1.
In contrast, the sequence {1, 2, 5, 6, 11, 13} is neither arithmetic nor geometric because there is no common difference or ratio, and it is not exponential because no base is being raised by an increasing power.

 The Architecture of the SCREEN System
In summary, the syntactic (semantic) plausibility of a word hypothesis sequence is evaluated by the degree of agreement between the disambiguated syntactic (semantic) category of the current word and the predicted syntactic (semantic) category of the previous word.
Since decisions about the current state of a whole sequence have to be made, the preceding context is represented by copying the hidden layer for the current word to the context layer for the next word based on an SRN network structure (Elman, 1990).
Figure 10 shows that the disambiguated basic syntactic representation of ``meine'' (``mean'') as a verb - and a very small preference for a pronoun - is mapped to the verb group category at the higher abstract syntactic category representation.

 BioMed Central | Full text | Automatic annotation of protein motif function with Gene Ontology terms
If one regards protein sequences as "sentences" of the biological language with amino acids as the alphabet, then protein motifs can be considered as words or phrases of that language and determining the function of a motif is equivalent to determining the sense of a word.
These databases are usually constructed by studying the set of protein sequences that are known to have certain functions and extracting the conserved sequence motifs that are believed to be responsible for their functions.
With the advent of algorithms and programs that can automatically discover sequence motifs from any given set of sequences [1,2,7-9], it is possible to mine a large number of sequences to find novel motifs without necessarily knowing their functions and to compile a dictionary of biological language accordingly.
