A dictionary part 15 arrays character sound symbols and all homonyms corresponding thereto by sequencing them, and thereafter, stores them correspondingly. A dictionary part 12 stores a correspondence table of reading symbols of each character for constituting a word and numbers of the array sequence of the homonyms in the dictionary part 15 of each character arrayed in order of constituting the word. A dictionary retrieving part 11 retrieves the dictionary part 12, and thereafter, derives a number of the array sequence of the homonym corresponding to a character of each component of the word corresponding to an inputted reading symbol column. A dictionary retrieving part 14 retrieves the dictionary part 15 and derives each structure character of words corresponding to the inputted reading symbol and based on the number of the array sequence of the homonyms retrieved by the dictionary retrieving part 11, each character is dived by a dictionary retrieval part 14. A word assembling part 13 assembles a word of a retrieval object, based on the inputted reading symbol and each character retrieved by the dictionary retrieving part 14.
Description
The present invention relates to the dictionary indexing unit of Chinese
Dictionary indexing unit in the past for example has the device shown in No. 75105839 communiques of TaiWan, China patented claim.Fig. 5 is the structural drawing that the Chinese-characters changing device of this dictionary indexing unit is housed.As shown in Figure 5, this Chinese-characters changing device is made of input block 100, syllabified code converter unit 110, Chinese character converter unit 120, dictionary retrieval unit 140, output unit 150.Input block 100 is a main member with the keyboard, and the pronunciation symbol of each text strings of word of retrieving is wanted in input.The pronunciation symbol string that syllabified code converter unit 110 sends input block 100 is transformed into the employed syllabified code of inter-process.Dictionary unit 140 is a critical piece with the storer, the Chinese terms pronunciation that storage is represented with syllabified code and with the group of the corresponding literal code of this word.Dictionary retrieval unit 130 includes microcomputer, and the content of the syllabified code retrieval dictionary unit 140 that goes out according to above-mentioned syllabified code converter unit 110 conversion is found the literal code of corresponding word.Chinese-characters changing device 120 can be by the text strings of output unit 150 outputs with above-mentioned dictionary retrieval unit 130 detect being transformed into pronunciation symbol string parallel expression literal code.As member, according to the signal that receives from Chinese-characters changing device, output specifically constitutes the text strings of searching object word to output unit 150 with printer, CR T etc.
But the basic structure of used dictionary unit is pronunciation symbol and the literal code that word ground storage one by one constitutes each literal of this word in the above-mentioned existing Chinese-characters changing device, and the literal of Chinese is a Chinese character, and the sum of Chinese characters in common use is more than 10,000.Therefore, and 2 bytes of the coding of each literal needs (16,2
16=65536) storage resources.For example, handle the Big5 sign indicating number that often uses in the computing machine of Chinese and taken in 13,051 literal, each literal is stored with the resource of 2 bytes.Therefore, with the dictionary unit that utilizes this kind sign indicating number to store 50,000 words is example, and each word on average is made of 2.5 literal, and each text pronunciation symbol and the literal code that constitute word need 2 bytes respectively, so, need (2.5 * (2+2) * 50000)=500K bytes of memory resource altogether.
The present invention in view of this, purpose be to provide a kind of can be for the utmost point of the word of retrieval dictionary indexing unit easily with less storage resources storage.
To achieve these goals, dictionary indexing unit of the present invention is characterized in that comprising:
Arrange the dictionary unit of back corresponding stored according to the order of sequence with the pronunciation symbol of each literal of Chinese and with the corresponding whole homophones of this pronunciation symbol;
To constitute the pronunciation symbol and the dictionary unit of pressing the homophony word arrangement sequence number corresponding storage of tactic each literal in above-mentioned dictionary unit that pronunciation symbol or word constitute of each literal of word one by one;
Retrieve word corresponding in the above-mentioned dictionary unit according to the pronunciation symbol of the word of wanting to retrieve, and take out the dictionary retrieval unit of the homophony word arrangement sequence number of each formation literal of word in above-mentioned dictionary unit that retrieves;
Pronunciation symbol and above-mentioned dictionary retrieval unit result for retrieval according to each literal are the homophony word arrangement sequence number of each literal in above-mentioned dictionary unit, retrieve above-mentioned dictionary unit, and take out the Dictionary retrieval unit of the literal that conforms to;
After above-mentioned Dictionary retrieval unit takes out each literal, according to when retrieval the word of importing pronunciation symbol in proper order, perhaps according to these literal of series arrangement of the arrangement sequence number in the dictionary unit, with the word assembled unit of combined retrieval object word.
By said structure, storage accordingly after the dictionary unit is arranged according to the order of sequence with the pronunciation symbol of each literal of Chinese and with the corresponding whole homophones of this pronunciation symbol.The dictionary unit will constitute one by one word each literal pronunciation symbol and according to homophone the put in order number of tactic each literal of pronunciation symbol in the dictionary storage that is mapped.When the corresponding character pronunciation symbol thought in the word of wanting to retrieve by the suitable business procedure of input block input or input and user, the dictionary retrieval unit is a search key with the pronunciation symbol of input promptly, and whether retrieval has corresponding word in the dictionary unit.Then, take out homophone the put in order number of each literal in the dictionary unit of the word that retrieves, and it is passed to the Dictionary retrieval unit.The Dictionary retrieval unit is retrieved in the dictionary unit according to each text pronunciation symbol of being imported and by the homonym number of the putting in order information that the dictionary retrieval unit retrieves, and takes out corresponding character according to the order of sequence, is passed to the word assembled unit.Each literal that the word assembled unit takes out the Dictionary retrieval unit according to the corresponding order of pronunciation symbol of input, perhaps arranged according to the order of the number of putting in order in the dictionary unit, with this with regard to combining searching object word.
As mentioned above,, in the dictionary unit, store homophone the put in order number of each literal in dictionary accordingly, replaced the internal code of each literal of word with the order of pronunciation symbol according to dictionary indexing unit of the present invention.At this moment, if each word on average constitutes with 2.5 literal, adopt the present invention after, it is just enough that the dictionary unit that has 50,000 words has 2.5 * (2+1) * 50000=375K bytes of memory resource.This compares with aforementioned existing dictionary unit, has reduced by 25% necessary storage resources.In fact, storage resources is different with the purposes of dictionary indexing unit itself, but often the dictionary element memory stores up 50,000 words and still falls down on.Therefore, the absolute magnitude of diminishbb storage resources is bigger, and its economic effect is splendid.In addition, dictionary unit itself is Miniaturizable also, thereby the retrieval rate in the dictionary is accelerated the processing speed raising.

Fig. 4 is the data structure synoptic diagram of dictionary unit in the foregoing description.
Fig. 5 is the Chinese-characters changing device structural drawing relevant with prior art that possesses dictionary unit and dictionary indexing unit.
Fig. 6 is external character complete list.
According to embodiment the present invention is described below.Fig. 1 is the Chinese-characters changing device structural drawing that utilizes one embodiment of the invention.As shown in Figure 1, this Chinese-characters changing device is made of input block 10, dictionary retrieval unit 11, dictionary unit 12, word assembled unit 13, Dictionary retrieval unit 14, dictionary unit 15 and output unit 16.The key word of the word that input block 10 inputs will be done to retrieve.In this example, input relies on keyboard to carry out, and is search key with the pronunciation symbol of syllabication sign indicating number.In addition also can be with the Chinese extracted out in the file as search key.Storage accordingly after dictionary unit 15 is arranged the pronunciation symbol of each literal of Chinese and all corresponding homophones thereof according to the order of sequence.Dictionary unit 12 is made of the table of comparisons, and this table of comparisons is to each Chinese terms, arranges each text pronunciation symbol of constituting word in order and according to homophone the put in order number of each literal of pronunciation symbol series arrangement in dictionary unit 15.Dictionary retrieval unit 11 will want the pronunciation symbol string of the word retrieved as search key, in dictionary unit 12, carry out electronic retrieval, if corresponding word is arranged, then will take out with the homophone number of putting in order of each literal in dictionary unit 15 that the pronunciation symbol of this word is stored accordingly.Dictionary retrieval unit 14 is made electronic retrieval according to the pronunciation symbol and the homophone number of putting in order of each literal in dictionary unit 15 of each literal that is taken out in dictionary unit 15, detect corresponding character.Each literal that word assembled unit 13 detects Dictionary retrieval unit 14 is according to the order of input pronunciation symbol string, perhaps according to the arrangement that puts in order of the homophone in the dictionary unit 12, is combined into the word as searching object.Output unit 16 is a member with printer, CRT, outwards output or show the word that is combined into by word assembled unit 13.
Secondly, to the data structure in dictionary unit and the dictionary unit, that is the storage mode in the storer describes.About the pronunciation of each literal of Chinese,, just can store each literal and its pronunciation accordingly by to the storage resources that utilizes certain-length behind its specific number.Therefore, can easily realize as shown in Figure 4 employing " ba ba ", " ba " (Fig. 6 1) (below, also because the relation of electronic information disposal system, external character unification is illustrated by Fig. 6, identifies with its sequence number.For example, " Fig. 61 " is meant the 1st external character among Fig. 6 or the external character string of being made up of a plurality of external characters.) wait the storage mode of pronunciation symbol.Equally, a plurality of homonymic number that put in order of each literal of word in the dictionary unit also the binary approach of available certain-length represent.The pronunciation of Chinese has 1,230 kind, and wherein the homophone of pronunciation " (Fig. 6 3) " is maximum, there are 145, still, as if with the byte being the unit storage, then can be with 2 pronunciations that bytes store Chinese is all, if re-use a byte, just can store the arrangement number of all homophone groups.(2
10＝102?4＜1230＜2048＝2
11，2
7＝128＜145＜256＝2
8)。Why at this is unit with the byte, is because CPU, general-purpose storage etc. require to handle with binary approach, generally is unit with the byte, just in time coupling therewith.
Hereinafter the word with " ba (Fig. 6 1) " shown in Figure 4 is an example, and storage mode is described.
File layout is " 00,100,110 01,010,001 01,011,101 0,011,001,000,000,001 00000011 ".
1st, the pronunciation of the 2 two byte " 00,100,110 01010001 " expression " ba ".The pronunciation of 3rd, the 4 two byte " 01,011,101 00110010 " expression " (Fig. 6 1) ".The homophone number of putting in order of the 5th byte " 00000001 " expression " eight ".The homophone number of putting in order of the 6th byte " 00000011 " expression " treasured ".The dictionary unit of present embodiment is with 2 pronunciations that bytes store Chinese is all, with 1 homonymic number of bytes store.
Fig. 2 is the processing flow chart of the Chinese-characters changing device of present embodiment.Followingly its processing procedure is described according to this figure.The pronunciation symbol (S1) of the Chinese terms retrieved is wanted in input at first successively.Then, whether exist with the dictionary retrieval unit in the retrieval dictionary unit and import pronunciation symbol parallel expression (S2).If there is not corresponding word, then finish retrieval actions, export corresponding demonstration.If corresponding word is arranged, then take out homophone the put in order number (S3) of each literal in dictionary that constitutes this word.The Dictionary retrieval unit carries out line retrieval according to the pronunciation mark of each literal of word and the homophone number of putting in order of above-mentioned dictionary retrieval unit taking-up in the dictionary unit, can obtain each literal (S4) that constitutes the searching object word with this.Each literal of the formation word that the word assembled unit will retrieve is according to input pronunciation symbol series arrangement, with this with regard to the desired word of one-tenth capable of being combined (S5).At last, output unit is outwards exported the searching object word (S6) that combines.
The content that shows above-mentioned processing below with concrete word.
Fig. 3 is the synoptic diagram of the data structure of dictionary unit in the present embodiment, and this dictionary unit is arranged according to the order of sequence with the pronunciation symbol of each literal and with corresponding all homophones of this pronunciation symbol.Fig. 3 Roman phonetic symbolic representation pronunciation symbol, the part situation conceptually is shown, homophone also can appear on the purposes such as Email sometimes, and it is stored in the inside after arranging by literal code order (from trend or conceptive, being the simple order of font) successively.Among the figure,, shown in the 1st row, like that, storing " eight " " crust " abreast for example with the corresponding homophone of pronunciation symbol " ba " ... Deng.Wherein, because " eight " are No. 1 position, so the homophone number of putting in order is 1.Equally, " crust " is in No. 2, and its serial number is 2.The 2nd row following with each pronunciation symbol corresponding a plurality of (all) homophone also be on basis with the method arrangement, set serial number more successively.
Fig. 4 is the synoptic diagram of data structure of the dictionary unit of present embodiment.This dictionary unit is made of the table of comparisons, in the table, the pronunciation symbol of word and homophone the put in order number of each literal in the dictionary unit that constitutes this word are arranged in order, for example, homophone the put in order number of each literal in dictionary 15 that constitutes this word of pronunciation symbol " ba (Fig. 6 1) " represented with " 1,3 ".Promptly, " 6a (Fig. 6 1) " this word, by " ba " the homophone number of putting in order " 1 " corresponding " eight " in the dictionary unit, and " (Fig. 6 1) " homophone number of putting in order " 3 " corresponding " treasured " in the dictionary unit constitutes, that is to say, during this pronunciation symbol string of input " ba (Fig. 6 1) ", be transformed into this text strings of text strings " eight treasures (choice ingredients of certain special dishes) " at last.
The action of the dictionary indexing unit of present embodiment is described with other example below.
(S1) time, the dictionary retrieval unit is retrieved in dictionary inside from input block input " ba (Fig. 6 2) zhi jiao ", searches whether there is the corresponding word (S2) with " ba (Fig. 6 2) zhijiao ".Because there is corresponding word the dictionary unit, so take out homophone the put in order number " 1,2,1; 1 of each literal in the dictionary unit that constitutes this word " (S3) after, send it to Dictionary retrieval unit with pronunciation symbol " ba (Fig. 6 2) zhi jiao ".The Dictionary retrieval unit according to " ba (Fig. 6 2) zhijiao " and " 1; 2; 1; 1; " " ba " and " 1 ", " (Fig. 6 2) " and " 2 ", " zhi " and " 1 ", " iiao " and " 1 " these pronunciation symbols and the homonymic number of putting in order are made up, in the dictionary unit, retrieve then, from a plurality of literal (Chinese character) that are consistent with each pronunciation symbol, take out " eight ", " visiing ", " it ", " friendship " (S4).After the word assembled unit obtains these literal that retrieve,, so just can form word " sworn brotherhood " (S5) with they series arrangement according to the pronunciation symbol of having imported.Output unit 16 is this word of having formed (S6) of output outwards.Finish the retrieval process of word by above action.
Secondly, this dictionary indexing unit carries out two kinds of retrievals to dictionary unit and dictionary unit, thereby has people's doubt may increase retrieval time, describes below at this point.Be used for the input key word that to want to retrieve and the pronunciation symbol of each word of dictionary unit most of actuation time of existing dictionary indexing unit and compare,, then directly take out the word of correspondence if consistent pronunciation symbol is arranged.And in the dictionary indexing unit of the present invention, be used for the input key word that will want the to retrieve pronunciation symbol by dictionary retrieval unit and each word of dictionary unit most of actuation time similarly and compare.If corresponding word is arranged, again each literal that constitutes this word is taken out from the dictionary unit one by one, be less than the word quantity in the dictionary unit far away owing to agree the quantity of different antonym, thereby to extract the used time one by one be unchallenged, and as use hereinafter numbers illustrated, because the capacity of dictionary unit reduces, so the retrieval in the dictionary unit can be accelerated on the contrary under a lot of situation.Therefore, not only inferior from the processing time unlike existing dictionary indexing unit, and also speed is fast all the better under many circumstances.
More than the invention has been described based on embodiment, the present invention obviously is not limited to the foregoing description.That is to say, in the scope that does not change main points, also the present invention can be done suitable distortion, give application implementation.For example:
1. the data structure of dictionary unit can not adopt the pronunciation symbol of first word, the such order of the homophone number of putting in order of each literal of back, so long as storage means of equal value, what is all right.Specifically, " ba (Fig. 6 1) " can store like this.
“00100110?01010001?00000001?01011101?0011001000000011”
In this delegation, the pronunciation of the 1st, 2 two byte " 00,100,110 01010001 " expression " ba ".The homophone number of the 3rd byte " 00000001 " expression " eight ", the pronunciation of the 4th, 5 two byte " 01,011,101 00110010 " expression " (Fig. 6 1) ".The homophone number of the 6th byte " 00000011 " expression " treasured ".
2. homonymic putting in order also can be determined according to methods such as usage frequency and stroke numbers.In addition,,, also need not be confined to use the numeral of order of representation, can certainly use the coordinate and the display seat aiming symbol of memory location as long as can from a plurality of homophones, specify certain specific word about homonymic " putting in order ".In addition, for example if usage frequency is as putting in order, then retrieval rate can further improve.
3. literal is a Chinese character in principle, and text strings is a Chinese terms, but picture
Chinese character and the foreign language as " あ ", " い " that such foreign country (being meant that certainly therefrom state's angle is seen) makes also can use, and foreign language and foreign language inherent noun as " special Xu ", " send out bright Association meeting " can certainly use.
4. as for purposes, no matter Chinese word processor, by the Chinese electronic dictionary of storages such as disk, relate to the automatic translating equipment etc. of Chinese yes which kind of all can use.
5. pronunciation symbol is that the phonetic symbol and second that also can adopt TaiWan, China to use at present overlaps phonetic symbol etc.
6. according to the comfort level of making etc., a plurality of members can be made of one.Also a member can be divided into a plurality of parts.
7. in addition, the dictionary unit and the dictionary unit of various Chinese dialects such as Shanghai native language, Cantonese can be set also, Fu Jiake selects to use the function of the dictionary unit and the dictionary unit of a certain dialect for the literal importer.Certainly, also available method of changing parts.
As mentioned above,, in the dictionary unit, store homophone the put in order number of each literal in dictionary accordingly, replaced the internal code of each literal of word with the order of pronunciation symbol according to dictionary indexing unit of the present invention.At this moment, if each word on average constitutes with 2.5 literal, adopt the present invention after, it is just enough that the dictionary unit that has 50,000 words has 2.5 * (2+1) * 50000=375K bytes of memory resource.This compares with aforementioned existing dictionary unit, has reduced by 25% necessary storage resources.In fact, storage resources is different with the purposes of dictionary indexing unit itself, but often the dictionary element memory stores up 50,000 words and still falls down on.Therefore, the absolute magnitude of diminishbb storage resources is bigger, and its economic effect is splendid.In addition, dictionary unit itself is Miniaturizable also, thereby the retrieval rate in the dictionary is accelerated the processing speed raising.
