Abstract

PURPOSE:To obtain a numeral converter allowed to convert the infinite number of numerals into a precise numeral mixing sentence in accordance with an inputted alphabetical sentence by providing fixed numeral conversion information. CONSTITUTION:An inputted alphabetical string ''twenty-first'' is sent to a numeral unit separating part 11 and divided into ''twenty'' and ''first''. Respective words are sent to a conversion information retrieving part 12, which retrieves a conversion information storage device 13 to obtain numeral conversion information corresponding to each word. Each numeral conversion information is sent to a numeral conversion part 14, which converts ''twenty'' into ''20'' and ''first'' into ''1st'' and outputs these converted results to a numeral coupling part 15. The coupling part 15 combines ''20'' and ''1st'' and outputs ''21st'' because ''20'' is the upper digit of the ''1st''.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a numeral conversion device that converts a numeral expression from a character string input in the alphabet into a sentence containing numbers.

[Technical background of the invention and its problems]

Ju 11 Hyunyo ka kira ra yuun in Wakusai H casting - For number words entered in alphabets, register them in the translation dictionary as alphabetical characters, and when searching the dictionary, read the corresponding dictionary information and use it as a number word. There was a way to handle it.

However, number words originally exist infinitely,
It was impossible to register all possibilities in a dictionary□. Furthermore, even if the minimum necessary number words are registered, the dictionary capacity increases and the search time also increases, which is still insufficient.

[Purpose of the invention]

The present invention has been made in view of this point, and its purpose is to provide a number word conversion device that converts number words manually written in the alphabet into sentences containing numbers, thereby enabling accurate machine translation processing. The purpose is to do so.

[Summary of the invention]

The present invention converts an alphabetic sentence into a sentence containing numbers using number conversion information stored in pairs of alphabets and numbers.

〔Effect of the invention〕

According to the present invention, efficiency is improved because all number words can be processed accurately without registering number words with infinite possibilities in a dictionary.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the overall configuration of an embodiment of the present invention. Conversion information search unit 2゜conversion information storage device 8. Number conversion unit 4. It has an output section 5.

First, alphabetic character strings input from the input section 1 are sequentially supplied to the conversion information search section 2. Conversion information search unit 2
searches the conversion information storage device 8 using the supplied alphabet character string, and if there is matching number conversion information, outputs it. If not, it is output as is to the output unit 5.

Here, the conversion information storage device 8 is a device that stores information necessary for conversion, such as numbers corresponding to alphabetic characters, as a table, and for example, a magnetic disk device is used.

The conversion information search unit 2 uses this as a search result and uses the number conversion unit 4 as a search result.
give to The numeral converter 4 converts an alphabetic character string into a corresponding number-mixed sentence using the given numeral conversion information. This number-mixed sentence is output from the output unit 5.

Next, a specific example will be explained according to FIG.

For example, let's consider a case where an alphabetic character string "twenty-first j" is input and converted into a sentence containing numbers.Here, the conversion information storage device 13 has a second
It is assumed that the number conversion information shown in the figure is stored.

First, the input alphabet string r twenty-
first J is sent to the number word unit extraction unit 11, and [
Twenty J and [first J i: Divided. Each unit is sent to the conversion information search section 12, and the conversion information search section 12 searches the conversion information storage device 13 to obtain number conversion information corresponding to each unit.

Each number word conversion information is sent to the number word conversion section 14, respectively. The numeral conversion unit 14 converts [twenty J into “20” and [first J into 11st J, and outputs them to the numeral combination unit J5.

The numeral combination unit 15 indicates that “20” is the upper digit of “ISt”
Since it is a numeral word, combine the two to form [21s
Output tJ.

In this way, if [twenty-first J is input, [21st, J] will be output as the conversion result. This operation is detailed in the flowchart of Fig. 3.
As described above, according to the present invention, by having certain number word conversion information, an infinite number of number words can be converted into an accurate number-mixed sentence corresponding to an input alphabetic sentence. equipment can be provided.
