Abstract
The invention provides a conversion dictionary generation device capable of generating a conversion dictionary used in a navigation device or the like, i.e., a higt efficiency (high inforamtion using rate per determined size of a conversion dictionary) conversion dictionary. A Chinese character string and a pinyin string (S115) are acquired from a POI-DB, and are analyzed to a Chinese character and a pinyin corresponding to the Chinese character. The a group (S120) composed by the Chinese character and the corresponding pinyin is produced, groups are cumulated to generate the conversion dictionary (S135). Thereby, the generated conversion dictionary includes conversion information of all Chinese characters required when using the POI-DB. In this way, compared with a conventional conversion dictionary, the efficiency of the conversion dictionary is very high.
Description
Technical field
The present invention relates to the technology of transfer dictionary of the generation Chinese that uses in the guider etc. and the technology of utilizing the transfer dictionary of this generation.
Background technology
We have known to have the transfer dictionary that use is mapped the symbol (phonetic) of the Chinese character of Chinese and its pronunciation of expression, pronunciation with phonetic input Chinese, convert thereof into the input in Chinese conversion processing unit (for example, patent documentation 1) of the function of Chinese character and output.We also know other various input in Chinese conversion processing units, and the function of this input in Chinese conversion processing unit also is used for guider.For example, use like this when setting the destination: the user imports sightseeing ground title or facility title with phonetic, convert thereof into Chinese character, obtain positional information with the search POI-DB of the Chinese character after the conversion (Point Of Interest-Database, interest point data base).
[patent documentation 1] TOHKEMY 2001-229155 communique
The transfer dictionary that the transfer dictionary that guider in the past uses the Chinese character that only defines as GB-2310 sign indicating number (JIS flip-flop that is equivalent to Japanese) to prepare phonetic sometimes is mapped as Chinese character and phonetic with Chinese.Yet the situation that only corresponding with GB-2310 sign indicating number Chinese character can't convert the Chinese character that the user requires to is also a lot, not enough as transfer dictionary.In addition, though considered to prepare phonetic for all Chinese characters of Unicode definition, but consider except that transfer dictionary big or small excessive, also the low-down Chinese character of frequency of utilization is comprised wherein, therefore as transfer dictionary poor efficiency (whenever the information utilization of Yu Ding transfer dictionary size is low).
Summary of the invention
The present invention is exactly in view of such problem, and purpose is will provide a kind of can generate the transfer dictionary that is used for guider etc.---and be the Chinese character converter that the transition dictionary generation device of the high transfer dictionary of conversion efficiency and the transfer dictionary that utilizes this generation carry out the Chinese character conversion.
The guider that uses in the Chinese circle has the Chinese character string of expression title and the database that is mapped with the corresponding pinyin string of this Chinese character string a lot as the situation of POI-DB.The present patent application person is based on this database, considers to utilize this database to make transfer dictionary.Be specially, from then on consideration obtains Chinese character string and pinyin string in the database by obtaining the unit, by generation unit make make each Chinese character and with the paired group of the corresponding phonetic of this Chinese character, these groups have been accumulated the transition dictionary generation device that generates transfer dictionary.
Required whole Chinese character transitional information when the transfer dictionary that generates by such transition dictionary generation device has been enlisted the services of and used POI-DB.Therefore, the transfer dictionary that generates by transition dictionary generation device of the present invention is so long as when being used for the Chinese character that signs in to POI-DB changed, compare efficient very high (the information utilization height of Yu Ding transfer dictionary size whenever) with the transfer dictionary of prior art.
But, consider place name that comprises a plurality of identical Chinese characters with identical pronunciation among the POI-DB etc.For example, if contain " Peking University " and " Beijing " such title among the POI-DB, the same pronunciation of " north " this Chinese character just is included in two titles.Suppose that under these circumstances generation unit can judge whether to have accumulated same group when generating transfer dictionary, only do not have the group of accumulation to accumulate just passable being judged as.
If like this,, therefore improved the efficient of transfer dictionary owing to can not repeat to accumulate the group that same Chinese character promptly has identical pronunciation.
In addition, accumulate when having above-mentioned group, the information relevant with the number of times of affirmative determination up to the present can be appended to (if additional then upgrade) and accumulate in the group in the transfer dictionary when generation unit is judged as.For example, when wanting to sign in to " north " this Chinese character in the transfer dictionary, added " 1 " if logined the value of " the affirmative determination number of times " that just will sign in to this group in the transfer dictionary with " Bei " this pronunciation.
If like this, just know that by seeing its number of times the pronunciation of this Chinese character was utilized several times in POI-DB, just can utilize this information during sequential scheduling when decision expression conversion candidate.
But generation unit can also generate the phonetic tree that can search in order with the corresponding pinyin string of Chinese character string except generating above-mentioned transfer dictionary.Here said phonetic tree is meant that each node is made of phonetic (for example " bei ") or the letter (for example " b ") that constitutes this phonetic, by make node from the root direction to leaf direction search (for example, " B " → " E " → " I " → " J " → " I " → " N " → " G " ... search) can constitute pinyin string.
If generate such phonetic tree, search this phonetic tree by phonetic or the pinyin string imported according to the user, can point out the candidate of the phonetic that next anticipation will import to the user.
And generation unit can also generate the Chinese character tree that can search the Chinese character that constitutes Chinese character string in order except generating above-mentioned transfer dictionary.Here said Chinese character tree is meant that each node is made of Chinese character, by make node from the root direction to constituting Chinese character string (Peking University) to leaf direction search (for example, " north " → " capital " → " greatly " → " " search).
If generate such phonetic tree, search this Chinese character tree by Chinese character or the Chinese character string determined according to the user, can point out the candidate of the Chinese character that next anticipation will determine to the user.
And the above-mentioned character string of expression title is the character string of expression POI title in the above-mentioned transition dictionary generation device, and the Chinese character string and the corresponding with it pinyin string of expression POI title also can be stored in the map data base of guider.Therefore in guider, can use effectively.
But, except each unit of above-mentioned transition dictionary generation device, can also constitute the Chinese character converter that has added with lower unit.Promptly, can constitute and add the unit of accepting from user's operation indication of accepting, inform the unit of informing of various information, according to accept the operation indication accepted the unit from transfer dictionary retrieval and the specific corresponding Chinese character of phonetic, with the Chinese character of searching at least one inform to inform the unit, then according to accepting the operation indication of accepting the unit, determine Chinese character converter with the control module spare of the corresponding Chinese character of phonetic.
The place names of the short of change login of such Chinese character converter in POI-DB etc. just can positively be carried out the Chinese character conversion, and are very easy to use concerning the user.
In addition, can be generation unit judge whether to accumulate when generating transfer dictionary same group, only accumulates being judged as the group that not have to store; And can be to accumulate when having above-mentioned group when generation unit is judged as, the information relevant with the number of times of affirmative determination is up to the present appended to (if additional then upgrade) and accumulate in the group in the transfer dictionary; And, can also be when control module the Chinese character that finds to be informed preferentially affirmative determination Chinese character often to be informed to informing the unit when informing the unit.
If user's operational ton in the time of like this, can reducing the Chinese character conversion.
And generation unit also can generate the phonetic tree that can search in order with the corresponding pinyin string of Chinese character string except that generating above-mentioned transfer dictionary.This moment, control module determined that the back is according to phonetic of having imported or pinyin string search phonetic tree, the phonetic of the leaf side gusset that will link to each other with the node corresponding to the last phonetic of importing is informed the unit as the candidate of the phonetic that the next one will be imported, accept operation when indication of the phonetic that means that selection has been informed when accepting the unit, the phonetic of this operation indication expression is handled as the phonetic of next importing.
If can reduce the operational ton of user's input Pinyin like this, can make user's Chinese character conversion operations become easy.
And generation unit can also generate the Chinese character tree that can search the Chinese character that constitutes Chinese character string in order except that generating above-mentioned transfer dictionary.This moment, control module determined that the back is according to fixed Chinese character or Chinese character string search Chinese character tree, the Chinese character of the leaf side gusset that will link to each other with the node corresponding to the last Chinese character of determining is informed to informing the unit as the candidate of the Chinese character that the next one will be determined, accept operation when indication of the Chinese character that means that selection has been informed when accepting the unit, the Chinese character that this operation indication is represented is determined as the Chinese character after fixed Chinese character or Chinese character string.
So also can reduce the operational ton of user's input Pinyin, can make user's Chinese character conversion operations become easy.
And the above-mentioned character string of expression title is the character string of expression POI title in the above-mentioned Chinese character converter, and the Chinese character string and the corresponding with it pinyin string of expression POI title can be stored in the map data base of guider.Thus, in guider, can use effectively.

[action specification]
The following describes the processing that control part 29 is carried out.In addition, the performed common process (for example, path setting processing, path computing processing, route guidance processing etc.) of general guider is well-known, therefore omits explanation.
(1) transfer dictionary generates and handles
At first, the transfer dictionary of carrying out with reference to the flowchart text control part 29 of Fig. 4 generates and handles.In addition, transfer dictionary generates and begins after the map data storage medium of handling after renewal is set in the map datum input unit 25.
When control part 29 began to carry out transfer dictionary generation processing, at first cancellation transfer dictionary and whole Chinese characters were set (S105).The details back of transfer dictionary and Chinese character tree is told about, and these all will be stored among the SRAM in the control part 29.
Then, judge whether from map data storage medium, to read whole records (S110) of above-mentioned POI-DB by map datum input unit 25.When being judged as when reading POI-DB and all writing down (S110:YES), finish this processing (transfer dictionary generates and handles), when being judged as (S110:NO) when not reading POI-DB and all writing down, move to S115 and handle.
Not reading among the S115 that moves to when POI-DB all writes down when being judged as, from POI-DB, read the record of not reading as yet, obtain Chinese character string and pinyin string.Then, respectively the Chinese character string and the pinyin string that obtain are decomposed, make the group of forming by a Chinese character and the phonetic corresponding (S120) with it.
Then, from the group that S120 makes, select one, organize retrieval conversion dictionary (S120) with this.
In this structure with the key diagram explanation transfer dictionary of Fig. 2 (b).1 record of transfer dictionary comprises " phonetic " corresponding with a word of Chinese character, with corresponding " Chinese character " of this phonetic and be illustrated in " the affirmative determination number of times " that is judged as sure number of times in the judgement that transfer dictionary generates the S130 in handling.
Return Fig. 4 and describe, in ensuing S130, carry out branch process (S130) according to the result for retrieval among the S125.When having the group of having chosen in the transfer dictionary (S130:YES), move to S140 and handle, when not having the group of having chosen in the transfer dictionary (S130:NO), move to S135 and handle.
Among the S135 that moves to when in transfer dictionary, not having the group of having chosen, phonetic and the Chinese character that constitutes this group is appended in the transfer dictionary.In addition, the affirmative determination number of times with this moment is set at " 0 ".Afterwards, moving to S145 handles.
And the affirmative determination number of times increase " 1 " that will write down among the S140 that moves to when in transfer dictionary, having the group chosen.Afterwards, moving to S145 handles.
In S145, judge whether all groups that constitute among the S120 have been retrieved transfer dictionary.When the result has retrieved transfer dictionary to whole groups for judging (S145:YES), move to S150 to handle, and, return S125 and handle when being judged as existence not (S145:NO) during the group of retrieval conversion dictionary as yet.
In being judged as the S150 that moves to when all groups having been carried out the transfer dictionary retrieval, judge whether to exist with S115 in the corresponding Chinese character tree of Chinese character string obtained.
Here, an example of setting with the key diagram explanation Chinese character of Fig. 3.The Chinese character tree that Fig. 3 represents is distributed to root node 41 with " north " word, and the node 42 that is assigned to " capital " word is connected with this root node 41 with the node 43 that is assigned to " sea " word.And the node 44 that is assigned to " greatly " word is connected with the node 42 that is assigned to " capital " word with the node 45 that is assigned to " city " word.And the node 46 that is assigned to " public affairs " word is connected with the node 43 that is assigned to " sea " word.And the node 47 that is assigned to " " word is connected with the node 44 that is assigned to " greatly " word, and the node 48 that is assigned to " garden " word is connected with the node 46 that is assigned to " public affairs " word.Therefore, Chinese character tree shown in Figure 3 just can constitute " Peking University " such Chinese character string according to 47 searches of root node 41 → node 42 → node 44 → node; Perhaps can search and constitute " Beijing " such Chinese character string according to root node 41 → node 42 → node 45; Perhaps can search and constitute " Beihai park " such Chinese character string according to root node 41 → node 43 → node 46 → node 48.In addition, a plurality of such Chinese character trees are stored among the RAM of control part 29.
Therefore, the judgement that " there is the corresponding Chinese character tree of the Chinese character string of obtaining with S115 in what is called " among the S150 of Fig. 4 is meant the Chinese character tree of the enough Chinese character string searches of existence energy node.
When being judged as (S150:YES) when having the corresponding Chinese character tree of the Chinese character string of obtaining with S115 among the S150, return S110 and handle; When being judged as (S150:NO) when not having the corresponding Chinese character of the Chinese character string of obtaining with S115 tree, move to S155 and handle.
Do not exist among the S155 that the corresponding Chinese character of the Chinese character string of obtaining with S115 tree moves to being judged as, generate and the corresponding Chinese character tree of this Chinese character string.Be specially, if there is no this Chinese character string Chinese character foremost is the Chinese character tree of root node, then generate the new Chinese character tree that can search this Chinese character string, if having had this Chinese character string Chinese character foremost is the Chinese character tree of root node, then append node so that can in this Chinese character tree, search this Chinese character string.Returning S110 afterwards handles.
(2) conversion process
Use the conversion process of flowchart text control part 29 execution of Fig. 5 below.In addition, when conversion process is set the destination in path setting is for example handled,, press and begin execution when diagram not have the shift key of expression from the phonetic of user's operating and remote controlling device 23a or action button group 22 input destinations.
After control part 29 begins to carry out conversion process, at first retrieval and the corresponding Chinese character of importing of phonetic (S205) from transfer dictionary.For example, if input " Bei " this phonetic is just retrieved the record that has this phonetic from transfer dictionary.
Then, judge whether to search this record (S210).When being judged as (S210:Yes) when finding this record, move to S220 and handle; When being judged as (S210:No) when not finding this record, move to S215 and handle.
In being judged as the S215 that moves to when not finding this record, show error messages by display part 26.Be specially, the information of the Chinese character of changing candidate etc. is not found in the demonstration expression.Finish this processing (conversion process) then.
In being judged as the S220 that moves to when finding this record, " Chinese character " that comprises in the record that finds is shown in the display part 26.In addition, when recording of having found is a plurality of, with their how many expressions in order by " number of times of affirmative determination ".
Then, judge whether the user has carried out meaning the operation (S225) of selecting the Chinese character of demonstration in the display part 26.This judgement is carried out telechiric device 23a or action button group's 22 input operation by monitoring.
When being judged as the selection operation that carries out Chinese character among the S225 (S225:Yes), moving to S230 and handle.When being judged as the selection operation that does not carry out Chinese character (S225:No), when this step is performed until the selection operation that has carried out Chinese character till.
Carried out determining among the S230 that the Chinese character selection operation moves to the Chinese character chosen being judged as.Here said " determining " is meant the corresponding correct Chinese character of phonetic that decision and user import and it is presented in the display part 26.
Then, retrieval is by the Chinese character tree (S235) of Chinese character of having determined or Chinese character string search.Here said " Chinese character of Que Dinging or Chinese character string " is meant the specific collection (for example, word units) that comprises the Chinese character of just having determined, promptly single Chinese character or a plurality of Chinese character.Can and Chinese character retrieval tree be meant at for example " Chinese character of Que Dinging or Chinese character string " when being " Beijing is big ", be along the judgement of the direction search " north " " capital " " greatly " from the root node to the leaf during the Chinese character of " north " word is set at root node.When there being root node is the Chinese character tree of " north " word, and can search in this Chinese character tree the time, is judged as " having found the Chinese character tree ".
Then, judge whether to have found Chinese character tree (S240).Be judged as and found Chinese character when tree (S240:Yes), move to S245 and handle,, finish this processing (conversion process) when being judged as (S240:No) when not finding the Chinese character tree.
Find among the S245 that the Chinese character tree time moves to being judged as, judge in the Chinese character tree of having found, searching when setting in the end with " Chinese character of Que Dinging or Chinese character string ", whether leaf one side of a node also is connected with node.If there is such node, just the Chinese character with this node is presented in the display part 26.For example, when searching " Beijing " in the Chinese character of Fig. 3 tree, the last node that searches is a node 42, and the node of the leaf side that links to each other of node is node 44 and node 45 therewith.Therefore, " greatly " and " city " is presented in the display part 26.
Then, in S245, judged whether to carry out the selection operation (S250) of the Chinese character of demonstration in the display part 26.This judgement is undertaken by monitoring the input operation that telechiric device 23a or action button group 22 carry out.When being judged as (S250:Yes) when having carried out the Chinese character selection operation, move to S255 and handle, when being judged as (S250:No) when not carrying out the Chinese character selection operation, move to S260 and handle.
In being judged as the S255 that moves to when having carried out the Chinese character selection operation, the Chinese character that carries out choosing is as the processing of determining Chinese character.Then, returning S235 handles.
And in being judged as the S260 that moves to when not carrying out the Chinese character selection operation, judge whether to have carried out the cancellation operation.This judgement also is to be undertaken by the input operation that supervision telechiric device 23a or action button group 22 carry out.Carried out when operation cancellation (S260:Yes) when being judged as, returned S250 and handle,, finished this processing (conversion process) when being judged as (S260:No) when not cancelling operation.
[effect of example]
By guider 20 according to above-mentioned example, carry out transfer dictionary and generate processing, generate the transfer dictionary of having enlisted the services of the whole Chinese character transitional informations that need when utilizing POI-DB.Therefore, the place name of short of change login in POI-DB etc. just can positively be carried out the Chinese character conversion.And, with only possessing of past the transfer dictionary of phonetic of Chinese character of GB-2310 sign indicating number definition or the transfer dictionary of phonetic that has possessed whole Chinese characters of Unicode sign indicating number definition compare, very high as the efficient of transfer dictionary.
And in transfer dictionary generate to be handled, the group of having logined Chinese character in transfer dictionary and phonetic is repeat logon (situation of No among the S130) no longer.Therefore, the group that same Chinese character promptly has an identical pronunciation is repeat logon not, so improve as the efficient of transfer dictionary.
And, in transfer dictionary generate to be handled, accumulate when having above-mentioned group when being judged as, the number of times of the judgement of so far answering affirmatively is appended to (S140) in the group of logining in the transfer dictionary.Then, when conversion process, preferentially affirmative determination Chinese character often is presented at (S220) in the display part 26.That is, preferentially show as the conversion candidate.
Therefore, if the preferential desired Chinese character of the Chinese character person of being to use that shows as long as determine that its operation is just passable, does not need to select in order to change operations such as candidate.Also just reduced the operational ton of user when selecting Chinese character.
And, generate in the processing at transfer dictionary, except that generating transfer dictionary, also generate the Chinese character of searching the Chinese character that constitutes character string in order and set (S155).Then, Chinese character retrieval tree (S235) in conversion process shows (S245) as the Chinese character after the Chinese character of determining.Again then, the Chinese character of choosing from the Chinese character that shows can be determined (S255) as the Chinese character after the Chinese character of determining.
Therefore, can reduce the operational ton of user's input Pinyin, make user's Chinese character conversion operations become easy.
[other examples]
In above-mentioned example, generate Chinese character tree (S130), carrying out Chinese character when conversion Chinese character retrieval tree (S235), then the high Chinese character of possibility that is determined is presented at (S245) in the display part 26, set and replace the Chinese character tree can use too but generate phonetic.
The example of phonetic tree is described with the key diagram of Fig. 6 here.In the phonetic tree as shown in Figure 6, " B " is assigned to root node 51, and the node 52 that is assigned to " E " is connected with root node 51 with the node 53 that is assigned to " I ".And, along the direction of the leaf place that several generations arrives of advancing, have the node 54 that is assigned to " X " at the node 52 that is assigned to " E ".And the node 55 that is assigned to " U " is assigned to " X " with this node 54 links to each other, and the node 56 that is assigned to " E " links to each other with the node 55 that is assigned to " U ".Therefore phonetic tree shown in Figure 6 can be according to root node 51 → node 52 ... → node 54 → node 55 → node 56 is searched and is constituted the such pinyin string of " BE...XUE " (implication of bei.jing da xue).In addition, can store a plurality of such phonetic trees among the RAM of control part 29.
Then, judge whether to exist the corresponding phonetic of the pinyin string that obtains with S115 to set to replace dictionary to generate treatment S 150,, generate the phonetic corresponding and set and replace S155 with this pinyin string when being judged as when not having such phonetic tree.Be specially, if there is no the letter foremost of this pinyin string is the phonetic tree of root node, then generate the new phonetic tree that can search this pinyin string, if having had this pinyin string letter foremost is the phonetic tree of root node, then append node so that in this phonetic tree, search this pinyin string.
When conversion process, the Chinese character that retrieval can be enough with definite or the phonetic of corresponding phonetic of Chinese character string or pinyin string search are set and are replaced S235.Be specially, at " Chinese character of Que Dinging or Chinese character string " when being " Beijing is big ", can judgement be along the direction sequential hunting " BEI JIN DA " from the root node to the leaf in the phonetic tree of " B " at root node.Then, be judged as under the situation about search, beginning to search node (for example, " X " → " U " → " E ") from the node that links to each other with last " A " again along leaf direction from the node branch that constitutes phonetic, to be presented at by the phonetic that they constitute (for example, " XUE ") in the display part 26.
If like this, when having the phonetic of next wanting to import in the phonetic candidate of user prompting, as long as select (that is, need not re-enter the letter that constitutes phonetic) just can input Pinyin.Therefore, improved the convenience that the user uses.
[with claims corresponding]
The term of being put down in writing in the term of the use in the above-mentioned example and the claim corresponding.Map datum input unit 23 is equivalent to obtain the unit, the dictionary that control part 29 is carried out generates handles the function that is equivalent to generation unit, action button group 22 and telechiric device 23a are equivalent to accept the unit, and display part 26 is equivalent to inform the unit, control part 29 and control module.
