In formal language theory, the left corner of a production rule in a context-free grammar is the left-most symbol on the right side of the rule. [1] For example, in the rule A→Xα, X is the left corner. The left corner table associates to a symbol all possible left corners for that symbol, and the left corners of those symbols, etc. Given the ...
In other languages that read text right-to-left, such as Persian, Arabic and Hebrew, text is commonly aligned "flush right". Additionally, flush-right alignment is used to set off special text in English, such as attributions to authors of quotes printed in books and magazines, or text associated with an image to its right.
The bbox - short for "bounding box" - of an element is a rectangular box around this element, which is defined by the upper-left corner (x0, y0) and the lower-right corner (x1, y1). the values are with reference to the top-left corner of the document image and measured in pixels the order of the values are x0 y0 x1 y1 = "left top right bottom"
Today, the left-to-right direction is dominant in all three languages for horizontal writing: this is due partly to the influence of English and other Western languages to make it easier to read when the two languages are found together—for example, on airport signs at a train station—and partly to the increased use of computerized ...
For example, English and many other Western languages are written in horizontal rows that begin at the top of a page and end at the bottom, with each row read from left to right. Egyptian hieroglyphs were written either left to right or right to left, with the animal and human glyphs turned to face the beginning of the line.
A woman writing in Persian in right-to-left direction, with a notebook computer displaying right-to-left text. Right-to-left, top-to-bottom text is supported in common computer software. [1] Often, this support must be explicitly enabled. Right-to-left text can be mixed with left-to-right text in bi-directional text.
In computer science, a left corner parser is a type of chart parser used for parsing context-free grammars. It combines the top-down and bottom-up approaches of parsing. The name derives from the use of the left corner of the grammar's production rules.
IPA letters have been incorporated into the alphabets of various languages, notably via the Africa Alphabet in many sub-Saharan languages such as Hausa, Fula, Akan, Gbe languages, Manding languages, Lingala, etc. Capital case variants have been created for use in these languages. For example, Kabiyè of northern Togo has Ɖ ɖ, Ŋ ŋ, Ɣ ɣ, Ɔ ...
