Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
The present invention goes for various language, for example, Chinese, Japanese, Korean, English etc. are because the application flow of the present invention in various spoken and written languages all is similar, so for convenience of description, only the present invention being applied in Chinese situation below describes.
The input mode that the present invention can adopt can comprise keyboard symbol, hand-written information and phonetic entry or the like, because the message switching mode in these input modes all belongs to known technology, has not just described in detail at this.
The personalized input process that the present invention realized can be used in numerous general or special purpose computingasystem environment or the configuration.For example: personal computer, server computer, handheld mobile device or portable set, plate equipment, multicomputer system, the system based on microprocessor, set top box, programmable consumer-elcetronics devices, network PC, small-size computer, mainframe computer, comprise distributed computing environment of above any system or equipment or the like.
With reference to Fig. 1, show a kind of method embodiment of character input, specifically can may further comprise the steps:
Described application program can comprise the various softwares that relate to content of text, for example, and Word, PDF, txt file, mail, immediate communication tool, web browser or the like.To describe in detail in the back of this instructions for concrete obtain manner.
General analytic process can comprise the participle statistic processes, for example, finds neologisms, statistics word frequency and statistics word relation information.General, interim dictionary can comprise entry, word order information and binary information.Because generally,, only add up binary information and get final product for the statistics of word relation.Described binary information is meant the annexation between the speech of expression text front and back, and (perhaps, Bigram), " binary " wherein refered in particular to the statistics of neighbouring relations in twos generally also can be called bigram statistics.For example, input information is " One is not a true man unless he comes to the Great Wall ", if we are with word during as the fractionation unit of minimum, we can split out " no " and " arrive " 7 individual characters in " length " " city " " non-" " good " " Chinese ", and binary wherein comprise " less than ", " to long ", " Great Wall ", " city is non-", " non-good ", " brave man ".Word frequency in the collected input information and binary combination relation can reflect that this user some vocabulary and language commonly used in daily input process uses style, thereby can satisfy this user's personalization input demand.
Need to prove that binary information also can be based on speech, perhaps between word and the speech also not only based on word.Certainly, in order to add up binary information, be to need a word-dividing mode based on speech.
Certainly, the present invention does not limit and only collects binary information, in fact says from effect, and the relation information that can collect n unit (n 〉=2) is better, just is limited to the computing power of present user terminal, and only obtaining binary information is the scheme of a comparative optimization.
Certainly, under the situation that computing power is allowed, described interim dictionary (for example can also comprise more information, probabilistic relation between word and the word, between word and the speech, words from application program or the like), its generative process also can adopt more accurate computing method, and the present invention does not need this to be limited.
Further, the generation of interim dictionary can also comprise some optimized Measures, for example, just can not need to join in the interim dictionary to some speech that does not meet prerequisite after the text data analysis, for example, the speech after ordering is leaned on very much, though perhaps the ordering in interim dictionary of this speech is forward, but it is forward also to sort in the existing dictionary of input method, and frequency is very high, then can get rid of outside interim dictionary.Described ordering generally is meant the ordering of the words that coded string is identical, for example, for spelling input method, then is exactly the ordering of the identical words of phonetic.
Step 103 loads existing dictionary of input method and described interim dictionary;
The existing dictionary of described input method can comprise the input method system dictionary, also can comprise input method user thesaurus or the like, and just being meant does not in a word need the interim dictionary that generates.
Described loading procedure can for: a dictionary merged in interim dictionary and existing dictionary, place buffer memory.The user can directly use according to the use-pattern of common dictionary in subsequent operation like this.Promptly when the user triggers certain interim dictionary, then should interim dictionary and existing dictionary merge, place buffer memory, the retrieval when being used for the user and importing.Certainly, can also the dictionary after merging in by adding mode such as mark, belong to interim dictionary or existing dictionary to distinguish certain entry.
Described loading procedure also can for: interim dictionary and existing dictionary are placed buffer memory as two independent dictionaries, and set dictionary priority according to presetting rule; Described priority is used for the demonstration ordering of candidate item.Generally speaking, the priority of interim dictionary is higher than existing dictionary.Promptly in loading procedure, interim dictionary is placed existing dictionary space specified in addition, and in the existing dictionary of retrieval, also retrieve interim dictionary.
Step 105 according to the input information that is received, is retrieved in existing dictionary of input method and described interim dictionary, obtains corresponding candidate item;
General, the weighted value of interim dictionary is greater than the weighted value of existing dictionary, for example, the simplest a kind of situation, search strategy can directly be set at the ordering of speech in the interim dictionary all prior to the speech in the existing dictionary.Certainly, also the mode that can set by the user or the mode by automatic setting are directly exported the entry in the interim dictionary with the fixed position.
Preferably, in the present embodiment, the search strategy of employing can for: when certain candidate item only retrieves, then export this candidate item in existing dictionary, and serve as according to sorting with the word frequency in the existing dictionary or other information; When certain candidate item only retrieves in interim dictionary, then export this candidate item, and serve as according to sorting with the word order in the interim dictionary or other information; When certain candidate item all finds, then can be weighted correction, according to revised word frequency sort (certainly, can store, also can not store) for revised word frequency to the word frequency in the existing dictionary in two dictionaries.
Further, the present invention can also adopt other feasible search strategies, for example, when generating interim dictionary, for each entry, calculates a weighted value (perhaps being weight parameter), and described weighted value is relevant with the word frequency in the existing dictionary of input method; Then, when when output coupling, according to this weighted value to the output of sorting of each candidate item.For example, a kind of simple implementation multiply by this weighted value by the word frequency of the word frequency of interim dictionary or existing dictionary and obtains parameters sortnig at this candidate item.
Step 104 to the realization of step 106 can be adopted existing various input method implementation, is not described in detail in this.
Need to prove that the generation of the interim dictionary described in the present embodiment can generate an interim dictionary at a document in the current system environments, for example, the user has opened 5 word documents, then generates 5 corresponding interim dictionaries.
Interim dictionary also can generate an interim dictionary at an application program in the current system environments, for example, though the user has opened 5 notepads, the content of text overall treatment in these 5 notepads is generated an interim dictionary; A ppt document of opening at this user generates another interim dictionary then.
Interim dictionary also can generate an interim dictionary at a plurality of application programs in the current system environments, and for example, the user has opened 1 word document, 1 notepad, a ppt document, then these 3 content of text that application program is related of overall treatment generate an interim dictionary.
Above-mentioned various generating mode (perhaps claiming generation strategy) can be applied to various occasion, and those skilled in the art select for use as required and get final product, and the present invention does not need the concrete generation situation of interim dictionary is limited.If generated a plurality of interim dictionaries, then can distinguish by sign between each interim dictionary, to point to correct input environment.
When having generated a plurality of interim dictionary, concrete loading procedure may change to some extent.General, can only load the pairing interim dictionary of the current document of operating of user and get final product.Certainly, also can load whole interim dictionaries, whether operate, give each interim dictionary different weighted values according to the user is current.For example, give the highest weighted value of interim dictionary of current operation, only retrieve this interim dictionary and existing dictionary during retrieval and get final product; Perhaps, also can retrieve a plurality of interim dictionary that weighted value is higher than certain threshold value.
Need to prove, be not to immobilize for the ordinal relation between the above-mentioned a plurality of steps in the present embodiment, illustrates it only is for convenience successively at this.For example, input method starts, and loads existing dictionary, obtains text data then and generates interim dictionary, loads interim dictionary; Certainly, also can finish obtaining and the generation of dictionary temporarily of text data in advance, when input method system starts, finish loading and get final product.
Obtain for data, can in the whole process of user's operation, accumulate; And generate for dictionary, then in fact can finish at any time.
After interim dictionary generated, As time goes on, the related content of text of application program may change (for example, the user has newly imported the content of text of 3000 words to the word document in a period of time), and then interim dictionary just needs to upgrade.Can carry out for the process of obtaining content of text always, when meeting prerequisite, (for example, satisfy the time interval of presetting) then, generate new interim dictionary and new and old interim dictionary, and then the notice input method load new interim dictionary.Because the data volume of interim dictionary is less, so its renewal process generally can not influence user's input behavior.Certainly, if data volume is bigger, then can be undertaken by asynchronous mode.
Preferably, present embodiment can also may further comprise the steps: store described interim dictionary, and the described interim dictionary of finishing analysis, obtain effective information, be incorporated in the existing dictionary of described input method.For example, with the temporary word library storage on the subscriber's local hard disk, utilize the computational resource of local system free time, all interim dictionaries are carried out finishing analysis, extraction meets the information of prerequisite--and effective information (for example, word frequency and 2 yuan of relations are greater than certain threshold value) merges to the mode of these information according to merger in the existing dictionary, thereby to a certain degree enriching the existing dictionary of subscriber's local, satisfying this user's individual demand from another angle.Interim dictionary behind the finishing analysis can be deleted from this locality, to reduce taking local storage resources.
Further, various modes can be arranged, for example, each user's interim dictionary be compiled,, find neologisms thereby analyze by server by the network end that uploads onto the server for the analysis of interim dictionary.Again for example, compile each interim dictionary, analyze the relation of each entry and input environment thereof (for example application name or type etc.), thereby form a plurality of respectively at special-purpose dictionary--the cell dictionary of certain specific environment, these neologisms or cell dictionary can offer other users, are used for further optimizing input method system.Certainly,, need from interim dictionary, remove the vocabulary of non-user's input, because the vocabulary of non-user input may bring inappropriate influence to analysis result in order to obtain cell dictionary accurately.For the input vocabulary that how to obtain the user, multiple implementation can be arranged, for example, can obtain by screen vocabulary on the intercepting and capturing input method, also can be when opening an application program as the user the difference of the text data that obtains and the text data that obtained after after a while, obtain this user's input vocabulary.
Below several modes that specifically may adopt of obtaining text data in the step 101 are introduced, only be used to illustrate realization of the present invention, and should not be construed as limitation of the present invention, those skilled in the art can also adopt other feasible modes to realize obtaining of text data.The present invention can be applied in the existing various operating system, for example, and Windows, Linux, MacOS, FreeBSD, Unix, Solaris or the like, and the PalmOS that is used for portable terminal, Windows Mobile, Symbian or the like.Following explanation is that example describes with Windows operating system commonly used only.
Obtain manner 1:, realize intercepting and capturing the purpose of content of text by monitoring computing equipment screen display content.For example, can obtain described text data by following steps: in operating system, preset the API Hook Function; When the videotex data, intercept and capture the output content of text output function.
With Windows operating system is example, general screen display content all needs to finish by text output function (for example TextOut etc.), then the present invention can realize the intercepting of screen text to the mode that API Hook Function (Hook function) is hung by system, as having write a jmp statement in the beginning of literal output functions such as TextOut, by the Hook function, jump in the good function of predefined, obtain the text of wanting TextOut to draw.
In this way, can obtain various text datas by screen display.For example, even mail communication message of opening, word document or the like.
Obtain manner 2 obtains by the mode that directly reads the text data in the file.For example, can obtain described text data by following steps: the path that obtains file; The com interface that provides by operating system reads the content of text of this document, perhaps directly reads the content of text of this document.
Particularly, for text (for example txt file), can directly read its text data.And for non-document file, existing operating system generally all provides the OLE technology, and OLE is the abbreviation of ObjectLinking and Embedding, can be translated as object linking and embedding.OLE is transmission and one group of comprehensive standard of shared information between client applications, and it allows to create the hybrid document that has the link of pointing to application program so that the agreement that needn't switch between application program during user's modification.The present invention can utilize the OLE technology to read the text data in most of file on the existing operating system.
For example, in the later operating system of windows 2000, provide the com interface of an IFilter, allowed application program to register this interface as files such as Office, PDF.The file that every application program of having registered this interface produces, other application program can read its content of text by this interface, and such as for files such as Office, Adobe, PDF, the present invention can read its content of text in this way.General process can for: obtain the IFilter object of corresponding document according to file path, judge that whether this document is registered, if this document is registered, then obtains content of text by IFilter::GetValue.
Wherein, how obtaining the path of file, is technical issues that need to address.The present invention provides several feasible modes: a here, the mode by the scanning system process obtains file path; B, obtain file path (for example, can be applied to mail, instant messaging supervisor, realize monitoring) by resolving its interface by the mode of monitoring application program interface; C, by the content of text of monitoring application program by screen display, learn file path (for example, obtain immediate communication tool the new store path that receives file).For example: in the chat window of live messenger, occur " You have successfully receivedE: Documents My Received Files txt.txt from (C). ", illustrate that then its file receives, and the file path that can therefrom will be referred to takes out.
By obtain manner 2, can obtain the various data in the file, comprise text data, also can comprise those not data by screen display by screen display, for example, a word document has 30 pages, and this input method user has only browsed preceding 5 pages, and adds annotations and comments to the 5th page, then by obtain manner 1, only can obtain preceding 5 pages text data, and, then can obtain all text datas of the document by obtain manner 2.By obtain manner 2, can also obtain the text data that does not belong in the current operation document, for example, the user has opened two word documents, is operating a document, by obtain manner 2, can obtain the text data in another document; And the user received a file by msn, but also do not open, and just can obtain text data in this document by obtain manner 2.
Obtain manner 3, the mode by the read operation system cache realize, for example clipbook.
The most existing application program all supports text resolution (for example, word), to simulate " full choosing (Ctrl_A) " " duplicating (Ctrl_C) " message at certain application program.If application program is handled these message, data just can enter clipbook; Then and then can obtain required text data by reading in the clipbook mode of data.Certainly, simulation " full choosing (Ctrl_A) " " duplicating (Ctrl_C) " message only is one gives an example, in fact can be by various keyboard combination message of simulation or mouse information, to reach choosing arbitrary text data in certain application program.
Preferably, embodiment shown in Figure 1 can also comprise the screening step: application programs is screened, and/or the text data of application programs screens; Therefrom remove some non-text datas, perhaps remove some non-input environments.
For example, the application program that the user opens is an audio/video player, or paint program, then the related text data of this application program is not just needed to obtain, when the program of user operation meets prerequisite (described prerequisite can be the program name of predefined or attribute etc.), just begin to obtain the step of text data or just begin to carry out analysis text data.
Again for example, though what the user opened is the word document, but when the text data that is obtained by obtain manner 1 can comprise some invalid datas (as, file, edit, attempt, literal such as toolbar title such as insertion, form, instrument, form, window and help), and these text datas can not reflect the environment of importing the user, so these text datas should not enter analysis process, therefore, can these invalid datas be screened out by some strategies that presets.
With reference to Fig. 2, show the embodiment of a kind of input method system of the present invention, specifically can comprise:
Text data acquisition module 201 is used for obtaining current system environments, the text data that application program is related;
Interim dictionary generation module 202 is used for described text data is analyzed, and generates interim dictionary 206;
The embodiment of this input method system can generate corresponding interim dictionary at user's input environment, to satisfy the demand of user individual input.
Obtain in the described text data acquisition module 201 text data mode can for: in operating system, preset the API Hook Function; When the videotex data, intercept and capture the output content of text output function.Described text data acquisition module 201 also can obtain described text data in the following manner: the path that obtains file; The com interface that provides by operating system reads the content of text of this document, perhaps directly reads the content of text of this document.Wherein, the path that can obtain file path or obtain new reception file by monitoring application program by scan procedure.Certainly, also can operate by analoging reproduction; From the operating system buffer memory, obtain the related text data of application program.
Further, this input method embodiment can also comprise: the system monitoring module be used for the current state of supervisory system, and when meeting prerequisite, notice starts the text data acquisition module; And/or, be used to monitor the text data that is obtained, and when meeting prerequisite, notice starts interim dictionary generation module.Further avoid invalid data handling procedure, improve counting yield.
Conflict for fear of interim dictionary and existing dictionary, and the accuracy that further improves ordering, present embodiment can also comprise the weight parameter generation module, be used for each entry at interim dictionary, according to the word frequency information in word frequency information in the interim dictionary and the existing dictionary of input method, obtain weight parameter, described weight parameter is used for the candidate item ordering.
In order further to utilize the text data that is compiled, then present embodiment can also comprise: the temporary storage module that is used to store described interim dictionary; And, be used for the described interim dictionary of finishing analysis, obtain effective information, be incorporated into the optimal module in the existing dictionary of described input method.
The embodiment of above-mentioned input method system can be common input method system, as, finish whole input process by the subscriber's local computing equipment, comprise information input, information translation and show output.The embodiment of above-mentioned input method system also can be the input method in network system, as, finish the access of input information by the subscriber's local computing equipment, and the demonstration of candidate item output, the information translation process is then finished in another computing equipment.Certainly, if be applied to the input method in network system, then the present embodiment interim dictionary that also needs to generate is sent to another computing equipment, perhaps the text data that obtains is sent to another computing equipment.That is to say that the present invention does not need to limit the particular geographic location of each module among the input method system embodiment, as long as have function corresponding and corresponding annexation.
With reference to Fig. 3, show a kind of generation method embodiment of interim dictionary, specifically can comprise:
Step 301 is obtained in the current system environments text data that application program is related;
Step 302 is analyzed described text data, generates interim dictionary; Described interim dictionary is used for retrieval and obtains candidates of input method.For example, generate after the interim dictionary, by the mode of the interim dictionary of notice input method system start-up loading, to be implemented in the effect of the interim dictionary of performance in user's input process.The generation of described interim dictionary can generate at an application document, also can generate at an application program, also can generate at a plurality of application programs.
Wherein, can obtain described text data by following steps: in operating system, preset the API Hook Function; When the videotex data, intercept and capture the output content of text output function.Perhaps, also can obtain described text data: the path that obtains file by following steps; The com interface that provides by operating system reads the content of text of this document, perhaps directly reads the content of text of this document.Certainly, also can operate by analoging reproduction; From the operating system buffer memory, obtain the related text data of application program.
Preferably, present embodiment can also comprise step 303, stores described interim dictionary; And, step 304, the described interim dictionary of finishing analysis obtains effective information.Described effective information can be incorporated in the existing dictionary of described input method, also can be used to obtain neologisms or be used for cellulation dictionary or the like.The present invention does not need the concrete application mode of the particular content of effective information and effective information is limited.
