Egyptian hieroglyphs, examples of logograms. In a written language, a logogram (from Ancient Greek logos 'word', and gramma 'that which is drawn or written'), also logograph or lexigraph, is a written character that represents a semantic component of a language, such as a word or morpheme.
The word problem for an algebra is then to determine, given two expressions (words) involving the generators and operations, whether they represent the same element of the algebra modulo the identities. The word problems for groups and semigroups can be phrased as word problems for algebras. [1]
Logogriph. A logogriph (not to be confused with logogram or logograph) is a form of word puzzle based on the component letters of a key word to be identified, and is derived from Greek λόγος, a word, and γρίφος, a riddle or fishing basket. It generally involves anagrams or other wordplay treatments such as addition, subtraction ...
Word problem for groups. In mathematics, especially in the area of abstract algebra known as combinatorial group theory, the word problem for a finitely generated group is the algorithmic problem of deciding whether two words in the generators represent the same element of . The word problem is a well-known example of an undecidable problem.
Ideogram. An ideogram or ideograph (from Greek idéa 'idea' + gráphō 'to write') is a symbol that represents an idea or concept independent of any particular language. Some ideograms are more arbitrary than others: some are only meaningful assuming preexisting familiarity with some convention; others more directly resemble their signifieds.
Logographic cues. Logographic cues are visual images embedded with specific, widely understood meaning; they are pictures that represent certain words or concepts. These pictures are "designed to offer readers a high-utility message in a minimum amount of space." [1] Some languages, for example, many East Asian languages, such as Chinese ...
Isometric graph paper or 3D graph paper is a triangular graph paper which uses a series of three guidelines forming a 60° grid of small triangles. The triangles are arranged in groups of six to make hexagons. The name suggests the use for isometric views or pseudo-three-dimensional views. Among other functions, they can be used in the design ...
In many texts in human languages, word frequencies approximately follow a Zipf distribution with exponent s close to 1: that is, the most common word occurs about n times the nth most common one. The actual rank-frequency plot of a natural language text deviates in some extent from the ideal Zipf distribution, especially at the two ends of the ...
