	Pattern Matching for Construct Validity
		Pattern matching always involves an attempt to link two patterns where one is a theoretical pattern and the other is an observed or operational one.
		The major differences between pattern matching and more traditional hypothesis testing approaches are that pattern matching encourages the use of more complex or detailed hypotheses and treats the observations from a multivariate rather than a univariate perspective.
		While pattern matching can be used to address a variety of questions in social research, the emphasis here is on its use in assessing construct validity.

	Pattern matching - Wikipedia, the free encyclopedia
		Pattern matching is the act of checking for the presence of the constituents of a given pattern.
		Depending on the languages, pattern matching can be used for function arguments, in case expressions, whenever new variables are bound, or in very limited situations such as only for sequences in assignment in Python.
		Pattern matching benefits most when the underlying datastructures are as simple and flexible as possible.

	WDVL: Perl Pattern Matching: Regular Expressions
		Pattern matching is an integral, but somewhat complex, aspect of Perl programming; in fact, pattern matching is the very basis of inspiration for using Perl in many programming tasks.
		Rudimentary pattern matching is probably familiar to many readers; in MS-DOS or Unix command lines, for example, you might request a directory listing for "*.txt" -- which, of course, means "all filenames which end with.txt".
		In the first, we test to see whether a match against a piece of data is true (matches) or false (does not match); in the second, we use the constructed template to perform a "search and replace" on a matched pattern within a piece of data.

	Selectors
		Matches element E if E is the source anchor of a hyperlink of which the target is not yet visited (:link) or already visited (:visited).
		matches a P element that is a grandchild or later descendant of a DIV element.
		It matches a P element that is a descendant of an LI; the LI element must be the child of an OL element; the OL element must be a descendant of a DIV.

	Pattern matching
		Pattern matching is important across a wide variety of Web programming tasks but most notably when looking for exceptions in user-entered data and when trying to parse information out of non-cooperating Web sites.
		It tests whether the string matches the pattern, returns 1 if there is a match and zero otherwise, and sets the match variable to the part of the string that matched the pattern:
		The pattern variables after the first are set to the substrings that matched the subpatterns.

		patterns, a regular expression is allowed to match anywhere within a string, unless the regular expression is explicitly anchored to the beginning or end of the string.
		matches a sequence of 0 or 1 matches of the atom.
		Subexpressions also match the longest possible substrings, subject to the constraint that the whole match be as long as possible, with subexpressions starting earlier in the RE taking priority over ones starting later.

	Categories of pattern matching characters
		Alternation and grouping matching- You wish to group characters to be considered as a single entity or add an "OR" logic to your pattern matching.
		Back reference matching- You wish to refer back to a subexpression in the same regular expression to perform matches where one match is based on the result of an earlier match.
		(\w+)\s+\1 matches any word that occurs twice in a row, such as "hubba hubba." The \1 denotes that the first word after the space must match the portion of the string that matched the pattern in the last set of parentheses.

	December 1997/Filename Pattern Matching (Site not responding. Last check: 2007-10-19)
		A pattern composed entirely of normal characters is a special case since it matches only one filename, the same filename as the whole pattern.
		Matching proceeds from the leftmost to the rightmost subpattern.
		This is accomplished by assuming that the closure subpattern initially matches zero characters in the filename (starting at the current position in the filename), and then recursively attempting to match the rest of the pattern against the rest of the candidate filename.

		Match Pattern property, Stylus Studio displays the input file in the Convert to XML Editor as shown in Figure 190 - green check marks identify the rows that match the pattern, and red X's identify the rows that do not.

	Day 7 -- Pattern Matching
		/\w\W/ matches a particular pair of characters, the first character is part of a word and the second is not; this means that the first character is the end of a word, and that a word boundary exists between the first and second characters matched by the pattern.
		matches a pair of characters, the first character is not part of a word and the second character is. This means that the second character is the beginning of a word.
		Because the pattern to be matched is too long to fit on one line, this program breaks it into pieces and assigns the pieces to scalar variables.

	AIML Pattern Matching Simplified (A.L.I.C.E. AI Foundation)
		The root of the Graphmaster is a Nodemapper with about 2000 branches, one for each of the first words of all the patterns (40,000 in the case of the A.L.I.C.E. brain).
		If no match was found, go back up the graph to the parent of this node, and put "X" back on the head of the input.
		A convenient metaphor for AIML patterns, and perhaps also an alternative to database storage of patterns and templates, is the file system.

	match
		A pattern expression is constructed with the aid of atoms and operators.
		AnyOf atom can be used instead of the alternation, it is preferable, because it is matched faster and the time of matching depends on neither the number of alternated characters nor their order.
		The user defined patterns are pre translated patterns which addresses are returned by the GetExternalPattern function, which binds unknown identifiers with user defined patterns.

	Pattern (Java 2 Platform SE v1.4.2)
		If a pattern is to be used multiple times, compiling it once and reusing it will be more efficient than invoking this method each time.
		The array returned by this method contains each substring of the input sequence that is terminated by another subsequence that matches this pattern or is terminated by the end of the input sequence.
		If this pattern does not match any subsequence of the input then the resulting array has just one element, namely the input sequence in string form.

	PostgreSQL: Documentation: Manuals: PostgreSQL 8.0: Pattern Matching
		Thus, writing a pattern that actually matches a literal backslash means writing four backslashes in the statement.
		It matches a match for the first, followed by a match for the second, etc; an empty branch matches the empty string.
		Once the length of the entire match is determined, the part of it that matches any particular subexpression is determined on the basis of the greediness attribute of that subexpression, with subexpressions starting earlier in the RE taking priority over ones starting later.

	Pattern Matching
		In this unit children explore lines of symmetry in pictures, shapes and patterns and describe the symmetry by stating that the parts on either side of the line of symmetry are the same.
		As far as geometry is concerned, symmetry is important in classifying shapes (regular polygons versus non-regular polygons), in patterns, in tessellations, and later in curves in co-ordinate geometry.
		The paper is then folded to create the matching pattern on the other side of the paper.

	MySQL AB :: MySQL 5.0 Reference Manual :: 3.3.4.7 Pattern Matching
		In MySQL, SQL patterns are case-insensitive by default.
		pattern match succeeds if the pattern matches anywhere in the value being tested.
		Because a regular expression pattern matches if it occurs anywhere in the value, it is not necessary in the previous query to put a wildcard on either side of the pattern to get it to match the entire value like it would be if you used an SQL pattern.

	Pattern Matching Pointers (maintained by Stefano Lonardi)
		Combinatorial Pattern Matching addresses issues of searching and matching strings and more complicated patterns such as trees, regular expressions, graphs, point sets, and arrays.
		The goal is to derive non-trivial combinatorial properties for such structures and then to exploit these properties in order to achieve improved performance for the corresponding computational problem.
		This area is expected to grow even further due to the increasing demand for speed and efficiency that comes from molecular biology, but also from areas such as information retrieval, pattern recognition, compiling, data compression, program analysis and security.
