Pronunciation adds the end in search key phonetic row.(step 408)
Further, the facility (step 410) that retrieval is matched with search key phonetic row from facilities database 36.In step
In rapid 410, in the next storage facility data of the corresponding node of the search key phonetic row with facilities database 35, right
The facility comprising search key Chinese character row in the facility name representing facility data enters line retrieval.
And, the facility retrieving is set as retrieval result facility (step 412).
Here, user, in order to retrieve facility [University Of Chongqing], in input Chinese character [weight], when Chinese character [celebrating], retrieves and closes
Key word Chinese character row have reformed in [Chongqing], and the acquiescence pronunciation of Chinese character [weight] is " zhong ", so search key phonetic row just become
" zhong " " qing ".And, as shown in Figure 6 a, in corresponding search key phonetic row in original installation data base "
Zhong " " qing " the bottom of node, does not have the facility data of storage facility [University Of Chongqing], so this [weight of user input
Celebrating], or, no matter inputted what Chinese character after this [Chongqing], facility [University Of Chongqing] all cannot be retrieved.The opposing party
Face, the facilities database 35 according to represented by the above-mentioned Fig. 6 b making, in corresponding search key phonetic row " zhong " " qing "
The bottom of node, also stores the facility data of facility [University Of Chongqing].So, input in this [Chongqing], or, after input
[big], [learning], can correctly retrieve facility [University Of Chongqing].
Then, return to and in Fig. 4, step 412, judge to be set as whether the facility quantity of retrieval result facility is less than N, and,
Judge whether comprise polyphone (step 414) in search key Chinese character row.Here N is more than 1 numeral, preferably 2 with
On numerical value.
And, it is judged as more than or equal to N, or be judged as not comprising the situation of polyphone in search key Chinese character arranges
Under, as shown in figure 5, show the facility number 505 (step 422) being set as retrieval result facility in search key input window.
And, show coming of key 504 to the generation (step 424) inputting Chinese character reception with using the result of search key input window
Monitored from the generation (step 426) of the result display instruction of user, in the event of (step if the reception of input Chinese character
424：It is), return to the process of step 406.On the other hand, (step 426 in the case of there is result display instruction：It is),
The catalog (step 428) of the facility name in the facility data being set as retrieval result facility of display storage, from display
In facility name catalog, the facility that receive user is selected, the facility number being stored in the facility selected in guider 37
According in setting coordinate become destination's (step 430), terminate title retrieval process.
On the other hand, in step 414, step 412 is set as that the facility quantity of retrieval result facility is less than N, and,
When judging to comprise polyphone in search key Chinese character row, convert dictionary 36 using phonetic, many in search key phonetic row
The pronunciation aliquot replacement of sound word becomes the pronunciation beyond this polyphone acquiescence pronunciation, generates phonetic row (step 416) after displacement.
Further, the facility (step 418) that retrieval is matched with the phonetic row generating from facilities database 35.In step
In 418, correspond in the facility data of the next storage of the phonetic row node that step 416 generates in facilities database 35, inspection
Rope comprises the facility of search key Chinese character row in the facility name of display facility data.And, the facility retrieving is added
It is added in retrieval result facility (step 420).
Here, the process being carried out by step 416-420, adding even for pronunciation does not have setting of storage in word list
Apply the facility that title comprises polyphone it is also possible to correctly enter line retrieval.
That is, the acquiescence pronunciation of polyphone [single] is " dan ", is stored in original installation data base, but wraps in facility name
During containing word [single field], the regular pronunciation of [single field] part in the facility name of this facility be all " shan " " tian " it is assumed that
Word [single field] is not stored into pronunciation and adds word list.
In this case, user, in order to retrieve facility [single field ××], when input Chinese character [single] and Chinese character [field], retrieves and closes
Key word Chinese character row have reformed in [single field], and search key phonetic has arranged into " dan " " tian ".But in this case, as Fig. 7 a
Shown, in facilities database 35, arrange the bottom of " dan " " tian " node in corresponding search key phonetic, because not storing up
Deposit the facility data that facility name comprises [single field], so the facility quantity setting in step 412 retrieval result facility is as 0, little
In N.Therefore, in this case, as illustrated, the search key Chinese character in search key phonetic row is arranged in [single field]
The pronunciation aliquot replacement of the polyphone [single] being comprised becomes the pronunciation " shan " beyond acquiescence pronunciation, generates phonetic row " shan " "
Tian ", arranges " shan " " tian " according to phonetic and enters line retrieval, is stored in corresponding phonetic and arranges the next setting of " shan " " tian " node
Apply in title the facility data comprising [single field] will be correctly retrieved.
Further, N is more than 2 numeral, due to carrying out the process of step 416-420, even if existing and the setting of user search
The Chinese character identical but different facility of pronunciation of row of the facility name applied, also can retrieve the facility that user wants.
I.e. it is assumed that the acquiescence pronunciation of polyphone [single] is " dan ", word [single field] is not stored in pronunciation and adds word row
In table, in original installation data base, except store comprise in facility name user want to retrieve word [single field] and [single
Field] part regular pronunciation be " shan " " tian " facility outside, also store and in M part facility name, comprise word [single field]
And [single field] part regular pronunciation be " dan " " tian " facility facility data.
In this case, user is crucial in order to retrieve facility [single field ××], input Chinese character [single] and Chinese character [field], retrieval
Word Chinese character row become in [single field], and search key phonetic has arranged into " dan " " tian ".And, in this case, as Fig. 7 b institute
Show, in facilities database 35, in the bottom arranging " dan " " tian " node corresponding to search key phonetic, store M part and set
Apply [single field] part in title regular pronunciation be " dan " " tian " facility facility data, so in step 412
The facility number being set in retrieval result facility is M part.Further, search key Chinese character row [single field] comprises polyphone [single].
Therefore, as illustrated, when M ＜ N, being wrapped in search key Chinese character row [single field] in search key phonetic row
The pronunciation aliquot replacement of the polyphone [single] containing becomes the pronunciation " shan " beyond acquiescence pronunciation, generates phonetic row " shan " "
Tian ", arranges " shan " " tian " according to phonetic and enters line retrieval, comprises to be stored in corresponding phonetic row " shan " in facility name "
The facility data of tian " node the next [single field] is also retrieved, and is added in retrieval result facility.
Here, if M number of packages is few, search key Chinese character row comprise polyphone, handle and the search key Chinese are stored
The phonetic that the search key phonetic row of word row are different arranges the facility of the facility name as pronunciation it is contemplated that this different phonetic arranges
Facility as the facility name of pronunciation is probably the facility that user wants to retrieve.Here, the number of packages less than N is considered as number of packages
Few, thus be excluded that while unnecessary retrieval, even if there is the identical reading of Chinese character row wanting retrieval facility name with user
It is also possible to retrieve the facility that user wants in the case of the facility of the different facility name of sound.
Next return in Fig. 4, step 418 and (walk if adding, in retrieval result facility, the facility retrieving
Rapid 420), as shown in figure 5, show the facility number 505 (step setting in retrieval result facility in search key input window
422).And, the generation (step 424) that input Chinese character is received and user utilize the result of search key input window to show
Key 504 come to carry out the generation (step 426) of result display instruction monitored, (step if such as input Chinese character receives and occurs
Rapid 424：It is), return to the process in step 406.On the other hand, (step 426 when result display instruction occurs：
It is), show facility name catalog (step 428) being stored in the facility data of facility of retrieval result facility setting,
The facility that receive user is selected from the facility name guide look of display, the facility being stored in selected facility in guider 37
Setting coordinate in data is destination's (step 430), and title retrieval process terminates.
It is more than the explanation with regard to embodiments of the present invention.
