METHOD AND APPARATUS FOR VECTORIZING TEXT WORDS IN A TEXT PROCESSING SYSTEM

摘要

Method and apparatus for vectorizing text words for compact storage and spelling verification in a text processing system without the use of complex mathematics functions. Each character in an input word is converted into a numerical value in decode means (7). The numerical values for the characters in a word are used to index into a magnitude table (30), the selected magnitude values being summed in adder (9) to produce a vector magnitude representation for the input word. The numerical values are also used to cumulatively access the binary table (17), the values output from this table being modulo-2 added and accumulated in a XOR (18) to produce a vector angle representation for the input word. The calculated magnitude and angle values are used to compactly store a dictionary a memory of correctly spelled words or for comparison to the stored dictionary.
