Embodiment
Describe the present invention in detail below with reference to accompanying drawing.
Fig. 1 is the process flow diagram according to the formula input method of intelligence combination of the present invention.With reference to figure 1, this formula input method may further comprise the steps:
The first step, that is, step S100, user import the coded string of formula.It is disclosed formula interface of input method in 200810239672.2 the Chinese patent application that application number can be adopted in the interface of input coding character string, and this interface comprises character input field and formula viewing area.Difference is that what the present invention imported is the coded string of whole formula in the character input field, rather than the title of operational symbol or symbol; What show in the formula viewing area is several candidates' formula, rather than the picture of operational symbol or symbol.That is to say that the present invention only need import the coded string of formula, just can obtain candidate's formula, and need not to carry out respectively step and character in this operational symbol of input or the symbol and the digital step of selecting operational symbol or symbol.The generation of candidate's formula will realize cutting coupling, integration and the composition step of describing by following.
In addition, the coded string of formula can adopt according to the Chinese spelling of the custom pronunciation of formula to be represented, also can adopt other Languages and spelling rules to represent.That is to say that the present invention is applicable to any input method that can directly import computing machine.Under the situation that adopts multiple input language and spelling rules, the user can select the input language and the spelling rules of desired use before the input coding character string, such as, english abbreviation, otherwise adopt the input language of system default and the input that spelling rules is accepted the user.Such as,
Under the situation that adopts the Chinese spelling, according to the custom pronunciation of Chinese, its coded string is " genhaoajiab ".
In second step, the coded string of input is handled, to obtain candidate's formula corresponding with coded string.
Second step is corresponding to the step S102 among Fig. 1, S104 and S106.Specific as follows:
In step S102, the coded string that the user is imported carries out cutting and coupling.Segmentation rules is according to the matching degree of the code table of formula input method the coded string of input being cut into a plurality of substrings, comprise to code table in the item substring that mates of the substring and not have of coupling or similar coupling fully.The substring of coupling is corresponding to one or more operational symbols, numeral, letter or special symbol in the code table.Such as, " genhao " is corresponding to operational symbol secondary radical
Radical repeatedly
, " a " is corresponding to alpha and English alphabet a.In the code table of formula input method, represent symbols such as operational symbol with codings such as numeral number or character strings usually.Therefore, we can say also that matching process is the substring of cutting and the process of the codes match in the code table.Not having the substring of coupling often to have certain semanteme, is that the input language that coded string adopts has, the substring such as " de ", " dao ".
Such as, coded string " genhaoajiab " according to segmentation rules, can cutting be " genhao a jia b ", wherein, and the secondary radical in substring " genhao " and the code table
Radical repeatedly
The codes match of these two operational symbol definition can preferentially be matched to the secondary radical
The English alphabet " a " in substring " a " and the code table and the codes match of Greek alphabet " α " can preferentially be matched to English alphabet " a "; The codes match of "+" in substring " jia " and the code table can be matched to operational symbol "+"; The English alphabet " b " in substring " b " and the code table and the codes match of Greek alphabet " β " can preferentially be matched to English alphabet " b ".
Again such as, coded string " ajiabdepingfang ", according to segmentation rules, can be cut into " a jia b de pingfang ", wherein, substring " de " does not have occurrence in code table, still, be the conjunction of often using in the Chinese custom pronunciation, in the integration process of back, it integrated; Substring " pingfang " can be matched to the quadratic power operational symbol.
In the cutting process, not exclusively mate, the item that promptly defines in the coded string of similar coupling and the code table is different, need be optimized coupling according to the implication of formula and the custom pronunciation of formula.Such as, coded string " sancigenxiaa ", be cut into " sanci genxia a " according to segmentation rules, wherein, the substring that can not mate fully " genxia " should be matched to operational symbol as a whole escape
" sanci " is matched to root time " 3 ".For another example, coded string " afenzhib " is cut into " a fenzhi b " according to segmentation rules, and wherein, the substring that can not mate fully " fenzhi " should be matched to
In addition, similar coupling comprises that also the coding approximate match with user's misspellings becomes the item that defines in the code table.Such as, the similar Chinese phonetic alphabet such as " pingfang ", " pinfang ", " pingfan " all can be matched to the quadratic power operational symbol.
In step S104, the content after the coupling is integrated, obtain candidate item.But integration rules is the operational symbol with editing area that the custom pronunciation according to the semanteme of coded string and formula obtains with coupling be the center with the data (comprising character and numeral etc.) of other coupling but be incorporated in the editing area of this operational symbol.But pronunciation are accustomed in position relation and Chinese according to the editing area of operational symbol, all operational symbols are divided into three kinds, promptly, fetch data from the left and right sides operational symbol integrated (such as, fraction, radical), the operational symbol integrated of fetching data from the left side (such as, index class) and the operational symbol (other operational symbol substantially all is this class) of fetching data and integrating from the right side.Simultaneously, in integration process, may run into the above-mentioned substring that does not have coupling, at this moment, these substrings be integrated according to the semanteme of coded string and the custom pronunciation of formula.Such as, in coded string " genhaoajiab ", there is an operational symbol " genhao ", can be matched to the secondary radical
But this operational symbol has an editing area, that is, and and the zone of the inside of radical.According to the custom pronunciation of formula, be the center with this operational symbol, but with the data integration of other coupling on its right side in the editing area of this operational symbol, can obtain candidate item
With
Deng.
Again such as, in coded string " ajiabdepingfang ", the substring " de " that has two operational symbols " jia " and " pingfang " and do not have coupling, wherein, operational symbol " pingfang " but have an editing area, the integration of fetching data from the left side.According to the difference custom pronunciation of different formulas,, then get the data in left side and integrate if do not have substring " de " in the front of " pingfang "; If there is substring " de " in the front of " pingfang ", then find " de " left side first unary operator before the one digit number certificate, be integrated into " pingfang " but editing area in.Therefore, in coded string " ajiabdepingfang ", first unary operator in " de " left side be " jia ", and one digit number certificate in its front is " a ", with " a " be incorporated into " pingfang " but editing area in, obtain " (a+b)
2".If the user imports " ajiabpingfang ", the last bit data " b " of then getting " pingfang " be incorporated into " pingfang " but editing area in, obtain " a+b
2".Certainly, for above-mentioned two coded strings, all can be with " (a+b)
2" and " a+b
2" as its candidate item, and according to the custom pronunciation the possibility size they are sorted.
Again such as, coded string " jifenadaobxpingfangdx ", cutting be " jifen a dao b x pingfang dx ", wherein, have two operational symbols " jifen " and " pingfang ".Operational symbol " jifen " is corresponding to a repeated integral, integration commonly used comprises definite integral and indefinite integral, but definite integral comprises three editing areas, be respectively upper limit of integral, lower limit of integral and integrand, integrand comprises integrand and " dx " or substrings such as " dy ", finishes the definition of this definite integral with " dx " substrings such as " dy ".For definite integral, the custom pronunciation does not have the substring " dao " of coupling to connect upper and lower bound in being commonly used in matching process.In integration process, get " dao " data " a " before as lower limit, get " dao " data " b " afterwards as the upper limit, data " xpingfang " after the capping, before " dx " or the substrings such as " dy " are as the integrand of definite integral, and " dx " or " dy " substring of etc.ing are integrated the sign of end as this definite integral.For operational symbol " pingfang ", as mentioned above, do not have " de ", then with its left side data " x " be incorporated into " pingfang " but editing area in.Therefore, coded string " jifenadaobxpingfangdx " is integrated into following formula the most at last:
In step S106, the coded data of candidate item is set type, that is, the coded data of candidate item is generated suitable formula form, and candidate's formula is presented on the candidate window selects for the user.Specifically, the coded data of candidate item is passed to the equation editing device that input system carries, generate the formula form by this equation editing device, and these candidate's formula are presented in the formula viewing area of formula interface of input method.With application number be that the difference of 200810239672.2 Chinese patent application is, what show in the formula viewing area is formula through setting type, rather than the picture of operational symbol or symbol.The present invention is applicable to the interactive formula typesetting software of different company.
The 3rd step, that is, step S108, the formula that the user is selected from candidate's formula is inserted in editor's space of a whole page.Inserting step by according to the implementation of former input system with candidate's formula convert to a series of instruction send to application program (such as, word, excel) realize.This step is a known technology, and the descriptions thereof are omitted here.
Fig. 2 is the structural drawing according to the formula input system of intelligence combination of the present invention, with reference to figure 2, this formula input system comprises input block 200, processing unit 300 and output unit 400, and wherein, input block 200 receives the coded string of the formula of user's input; The coded string of 300 pairs of receptions of processing unit is handled, to obtain the candidate formula corresponding with coded string; Output unit 400 is selected the user from candidate's formula formula is inserted in editor's space of a whole page.
Processing unit 300 comprises coding cutting matching unit 302, integral unit 304 and formula composing unit 306.
The coded string of 302 pairs of user's inputs of coding cutting matching unit carries out cutting and coupling.Specifically, according to the matching degree of the code table of formula input method with the coded string of input be cut into to code table in the item substring that mates of the substring and not have of coupling or similar coupling fully.
Content after 304 pairs of couplings of integral unit is integrated, and obtains candidate item.Specifically, but be that the center is integrated, comprise the substring that does not have coupling in matching process is integrated according to the operational symbol that the custom pronunciation of the semanteme of coded string and formula obtains with coupling with editing area.
The coded data of the 306 pairs of candidate item in formula composing unit is set type, and, the coded data of candidate item is generated suitable formula form that is, and candidate's formula is presented on the candidate window selects for the user.
Can find out from above embodiment, according to formula input method of the present invention and system the coded string of user's input is carried out cutting, coupling and integration, coded string is converted to the formula form to import similar mode with the intelligent word of input method of Chinese character and long and short verse.For the user, only need once to import the coded string of whole formula, select corresponding occurrence then, just can a step whole formula be presented on the screen.Compare with the title that once can only import an operational symbol or symbol and the prior art need be between formula interface of input method and non-formula interface of input method switched back and forth, owing to can directly import the coded string of whole formula, and need not between different interfaces, to switch back and forth, therefore, improved the input efficiency of formula.
