Description
Technical field
The present invention relates to the retrieval technique of electronic equipment, particularly a kind of intelligent search method that can be used for small keyboard electronic dictionary.
Technical background
Along with development of electronic technology, the function of many traditionally on paper medium (as books, newspaper, dictionary etc.) can be finished with electronic equipment, and electronic dictionary also becomes an important function on the electronic products such as numerous mobile phones, PDA, instant translator, learning machine, MP4 day by day.
Retrieval is to realize one of gordian technique of electronic dictionary.In traditional Dictionary retrieval, input is to determine unambiguously, thereby the retrieval of dictionary is a kind ofly to search one to one, promptly finds out in dictionary and imports identical word, speech or phrase.For example, on some electronic products such as computing machine, instant translator, PDA, 26 English alphabets all have button one to one, and the input method that other language beyond the English is also had many maturations, therefore word, speech or the phrase of input do not have ambiguity substantially, on these electronic products, the retrieval of electronic dictionary promptly is to find out correspondingly in dictionary and import identical word, speech or phrase; On some middle and high end electronic products, although its button is less than 26, possess handwriting input device, can not produce ambiguity by method input word, speech or the phrase to be looked into of handwriting input yet, the retrieval of its electronic dictionary is to search one to one equally.
Yet in practice, electronic product is considered for aspects such as cost, volume, practicality greatly, do not have button or handwriting input device more than 26, the input of electronic dictionary need be finished by a few button, this moment is owing to be less than alphabetical number by bond number, a button may be represented a plurality of letters, will can produce fuzzy during input inevitably and ambiguity, make traditional dictionary one to one retrieval mode can't normally carry out.For example, the standard CC ITT keyboard on the mobile phone, numerical key " 2 " has been represented English alphabet " abc ", and during promptly by " 2 " key, the user might think any one among input alphabet " a ", " b " or " c ".In this case, if also use traditional method to carry out Dictionary retrieval, then fuzzy the and ambiguity that must adopt some particular processing to eliminate input at input phase earlier just can be carried out.For example, at present widely used a kind of method on the mobile phone with the ccitt standard keyboard on " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 " and " 9 " eight numerical keys are represented English alphabet " abc " respectively, " def ", " ghi ", " jkl ", " mno ", " pqrs ", " tuv " and " wxyz ", determine the letter that to import by the number of times of record repeated presses numerical key, promptly, when needing input alphabet " c ", then push " 2 " key 3 times, when needing input alphabet " x ", push " 9 " key 2 times, so analogize, need to determine the word of input on no ambiguity ground, speech, or behind the phrase, carry out conventional Dictionary retrieval again.Other common methods also have: two buttons are set, repeated presses one of them can the select progressively English alphabet, another can inverted sequence select English alphabet repeated presses, carries out the no ambiguity input and the Dictionary retrieval of letter with this; By " on ", letter on D score, " left side ", " right side " key keypad selecting to show on the screen finishes the no ambiguity input and the Dictionary retrieval of letter, or the like.These class methods all have a significant disadvantages, need in a large number button repeatedly when promptly importing, and input efficiency is low, use very inconvenient.In order to reduce touch potential, improve input efficiency, some improved dictionary intelligence input/search methods have appearred in the ccitt standard keyboard at mobile phone in recent years, these methods are not handled especially to the ambiguity of input phase button, eliminate but in retrieval phase its ambiguity is carried out intelligence, can accomplish each letter only by one-touch, can demonstrate to need word, speech or the phrase imported, reduce the number of times of button significantly, improved input efficiency.But these methods still are confined to the ccitt standard keyboard at present, some electronic dictionaries of pressing on the bond number electronic product (as learning machine, MP4 etc.) are still less retrieved, still do not have effective solution at present, generally can only adopt in the method for input phase elimination button ambiguity and carry out.
Summary of the invention
The present invention is directed to traditional dictionary picking up method and can only handle accurate unambiguous input, cause at present at learning machine, touch potential is many when using electronic dictionary on the less electronic product of buttons such as MP4, input efficiency is low, use shortcomings such as inconvenience, a kind of intelligent search method of electronic dictionary is provided, this method can accept to blur and have the input of ambiguity, combination according to the input button, by intelligent association in retrieval phase, can be on button less standard or non-standard keyboard, particularly be applied on the keypad of 5 buttons, realize that each character that need import is only by primary key, can demonstrate possibly the input word, speech or phrase are selected for the user, needed touch potential when reducing Dictionary retrieval effectively, improved input efficiency, and realize simple, operand is low, can be widely applied on the multiple electronic product with electronic dictionary function.
In order to realize the foregoing invention purpose, the technical scheme of employing is as follows:
A kind of intelligent search method of small keyboard electronic dictionary comprises off-line cataloged procedure and on-line retrieval process; Described off-line cataloged procedure comprises the steps:
(1) button of electronic dictionary is encoded, each button distributed in the character that input character is concentrated, set up character-button-coding mapping table, and convert the word in the electronic dictionary, speech, phrase to coded strings according to this character-button-coding mapping table;
(2), serve as according to the order of adjusting dictionary with the coded strings that generates in the step 1, and set up index for dictionary;
Described on-line retrieval process comprises the steps:
(3) receive the keyboard input, be converted to according to character-button-coding mapping table of setting up in the step 1 and encode and note;
(4) according to the input coding that has write down and the index of dictionary, find the word identical or relevant, speech or phrase with this coding;
(5) word, speech or the phrase that find are listed on screen;
(6) user shows the explanation of this word, speech or phrase on screen after selecting word, speech or the phrase that oneself need search on the screen.
In the technique scheme, described step 1 specifically comprises the steps:
(1.1) button on the applied keyboard is encoded;
(1.2) set the condition that the coding repetition rate need satisfy;
(1.3) each button distributed in the character that input character is concentrated, and set up character-button-coding mapping table;
(1.4) convert each word, speech or phrase in the electronic dictionary to coding according to character-button-coding mapping table of setting up in the step 1.3;
(1.5) number of the word that coding repeats in the statistics dictionary, speech, phrase; If the coding repetition rate does not satisfy the requirement that step 1.2 provides, then revise the character allocative decision, and change step 1.3; Otherwise note current character-button-coding mapping table as final alphabetical allocation result.
In the described step 2, the word in the dictionary, speech or phrase sort according to the most similar principle of coding.
In the described step 4, search coding word, speech or the phrase identical with current input coding.
In the described step 4, except searching coding word, speech or the phrase identical with current input coding, searching coding simultaneously is to be other words, speech or the phrase of prefix with the present encoding.
Also search with the present encoding when being other words, speech of prefix or phrase when described step 4, it is searched and can carry out by the following method:
(4.1) buffer queue is set, its size can be held word, speech or the phrase that the screen of electronic dictionary can show at least;
(4.2) find the start address of word, speech or the phrase identical with current input coding;
(4.3) sequential search word, speech or phrase backward, if the code length of current word, speech or phrase is less than the length of the coding of current input, or code length equals the code length of current input, but it is inequality with the coding of current input, or arrival dictionary end, then exit find, be in the buffer queue by the good lookup result of character length series arrangement from small to large;
(4.4) with the current word that finds, speech or phrase by number of characters few preceding, number of characters many after principle insert buffer queue, and change step 4.3 and proceed.
When input character collection of the present invention was 26 English alphabets, the character in the described step 1.3 distributed and can realize in order to following method:
(1.3.1) 26 English alphabets are arranged by the order of people's input habit;
(1.3.2) hypothesis has N button, and N＜26 then will be arranged 26 good English alphabets and are divided into the N section, distribute to a button for every section.
The order of the people's input habit described in the described step 1.3.1 can adopt the natural order of English alphabet " a-z ", also can adopt putting in order of English alphabet on the computer standard keyboard.
As using preferred plan of the present invention, the keyboard of described electronic dictionary has five buttons, and with " abcd ", " efghij ", " klmno ", " pqrs ", " tuvwxyz " distribute to button 1, button 2, button 3, button 4, button 5 respectively.

Embodiment
The present invention is described further below in conjunction with accompanying drawing.
The example of English-Chinese/Chinese-English double-dictionary retrieval that the present invention uses 5 buttons to realize on certain electronic installation specifies embodiments of the present invention.
Embodiment of the invention hardware configuration is made of jointly microcontroller circuit, keyboard interface circuit, liquid crystal display circuit, memory circuitry and other functional circuits as shown in Figure 4.Electronic dictionary is in the numerous functions of present embodiment, and other functions can be music, movie, picture demonstration, text display or the like, since little with relation of the present invention, no longer be described in detail here.In realizing electronic dictionary intelligent search method provided by the invention, microprocessor is mainly finished following function: 1, the demonstration of operation interface; 2, receive the keyboard input; 3, the retrieval of dictionary and result's demonstration.Keyboard interface circuit, liquid crystal display circuit are connected with microprocessor with control line C by data line B, finish communicating by letter and control function between microprocessor and keyboard, the LCDs respectively.Memory circuitry links to each other with microprocessor with control line C by address wire A, data line B, for microprocessor provides jumbo external memory space, is used for the storage of electronic dictionary and related data.Decoding scheme links to each other with microprocessor by address wire A, for each peripheral chip provides chip selection signal.Other functional circuits are that system realizes other the every functions except that electronic dictionary.
Circuit theory diagrams as shown in Figure 5, microcontroller circuit, keyboard interface circuit, liquid crystal display circuit, memory circuitry, decoding scheme are made of jointly microprocessor chip IC1, keyboard interface chip IC 2 and keyboard array, LCD display control chip IC3 and LCD display, storage chip IC4 and coding chip IC5 and their correspondent peripheral circuit respectively.Wherein IC1 can adopt 16 dsp chip TMS320C5409; IC2 can adopt 74LS244; IC3 can adopt the K0713BT-01 of Sumsung; IC4 can adopt M29W400B; IC5 can adopt 74LS138.Other functional circuits can adopt IC chip and the peripheral circuit thereof of realizing corresponding function to realize.
Implementation process of the present invention such as accompanying drawing 1 be, realize the intelligent retrieval of English-Chinese/Chinese-English double-dictionary, the process of its enforcement is divided into off-line phase and online stage, wherein off-line phase is mainly finished the generation of English alphabet-button-coding mapping and encoder dictionary, its flow process as shown in Figure 2, this stage is similar to the disposal route of english Chinese dictionary and Chinese-English dictionary, in the embodiment that is applied to 5 buttons, the concrete steps of off-line phase as shown in Figure 6:
At first 5 buttons that are used for the dictionary input are encoded.Use because coding is just inner, therefore code word can be selected unduplicated 5 symbols arbitrarily, for example, 5 buttons can be encoded to " 1 ", " 2 ", " 3 ", " 4 ", " 5 " respectively, also can be encoded to " a ", " b ", " c ", " d ", " e " etc., a kind of coded system before present embodiment adopts.
After keyboard-coding finishes, set the condition that letter distributes back dictionary encoding repetition rate to satisfy.The setting of this condition is foundation with the actual needs, is subjected to the vocabulary of dictionary, by the influence of factors such as bond number, code length, can be to specify the maximum coding repetition rate upper limit, also can be meant forms such as allocating the repetition rate upper limit of all encoding.Present embodiment adopts the method for specifying the maximum coding repetition rate upper limit, the maximum repeated code number of regulation english Chinese dictionary must be less than screen English words, speech or the phrase number that can show at most, Chinese words, speech or phrase number that the maximum repeated code number of Chinese-English dictionary must can show at most less than a screen.
After the condition that given dictionary encoding repetition rate need satisfy, promptly enter alphabetical allocated phase.26 letters are assigned on 5 buttons, because alphabetical number is more a lot of than howing by bond number, so each button need be represented a plurality of letters.The principle of distributing is to meet the general custom of people's input and make the maximum coding repetition rate of the coding of speech in the dictionary satisfy given requirement.This process can be carried out according to the following steps:
1, according to people's input habit, 26 letters are arranged in proper order by certain, for example, can put in order by the letter of " abcdefghijklmnopqlstuvwxyz " and arrange, also can be according to the button order of Qwerty keyboard on the computing machine, promptly the order of " qwertyuiopasdfghjklzxcvbnm " is arranged.Present embodiment has adopted putting in order of English alphabet.
2, will arrange good letter and be divided into 5 sections, and distribute to a button for every section, and obtain a letter-button-coding mapping table thus.For example, can be with " abcd ", " efghij ", " klmno ", " pqrs ", " tuvwxyz " distribute to respectively and are encoded to " 1 ", and " 2 ", " 3 ", " 4 ", on the button of " 5 ", the letter-button of formation-the coding mapping relations are as shown in Figure 7.
3, according to the letter-button-coding mapping table that has got, word to Chinese and English all in the dictionary, speech, phrase is encoded, wherein, for the English words in the english Chinese dictionary, speech, phrase, can directly be converted to coding, for the word of the Chinese in the Chinese-English dictionary by letter-button-coding mapping table, speech, phrase can carry out code conversion according to its phonetic alphabet, for example, if with " abcd ", " efghij ", " klmno ", " pqrs ", " tuvwxyz " distributes to respectively and is encoded to " 1 ", " 2 ", " 3 ", " 4 ", on the button of " 5 ", then the English word in the english Chinese dictionary " hello " can be converted to coding " 22333 ", the Chinese in the Chinese-English dictionary " hello ", adopt phonetic " nihao " to encode, can be converted to coding " 32213 ".It should be noted that, because some English word or the Chinese phonetic alphabet may comprise a lot of letters, therefore except the coded system that all is converted into coding, also can be as required only a part be wherein carried out encoding process, for example, only preceding 6 to word or phonetic encode, English word in the english Chinese dictionary " dictionary " can be converted to coding " 121523 ", Chinese in the Chinese-English dictionary " China ", by its phonetic " zhongguo ", can be converted to coding " 523322 ".Such processing can reduce the size of index, but can increase the coding repetition rate.
4, the statistics number of times that coding repeats in the dictionary under present alphabetical allocative decision, and note maximum coding repetition rate.
5, the maximum of more present alphabetical allocative decision coding repetition rate and the maximum of the setting repetition rate condition of encoding, if do not satisfy condition, repeating step 2-5 then is till the alphabetical allocative decision of the condition of being met.
Present embodiment is through after optimizing and revising, English-Chinese and Chinese-English dictionary is adopted unified alphabetical allocative decision, be about to " abcd " " efghij ", " klmno ", " pqrs ", " tuvwxyz " distribute to respectively and are encoded to " 1 ", " 2 ", " 3 ", " 4 ", the button of " 5 ", the letter-button of formation-the coding mapping relations are as shown in Figure 7.
After letter has assigned, according to letter-button-coding mapping table, the phonetic of the Chinese words in the English words in the english Chinese dictionary, speech, phrase and the Chinese-English dictionary, speech, phrase is converted to respective coding, and the Chinese words in the dictionary, speech, phrase is sorted according to the most similar principle of coding.The principle ordering that described coding is the most similar, the coding of promptly adjacent two words, speech, phrase has only one difference, as arranging according to the order of " 1-11-111-1111-11111-111111-111112-111113-... ".After English-Chinese and Chinese-English dictionary sequences preface, generate separately index according to its coding respectively, at last in the storer with the index data writing system of the English-Chinese and Chinese-English dictionary data that generated and correspondence thereof.
After finishing above preliminary work, can carry out the retrieval of online English-Chinese or Chinese-English dictionary by using system, the process of retrieval at first is provided with a buffer queue as shown in Figure 3, and its size can be held word, speech or the phrase that the screen of electronic dictionary can show at least; Find the start address of word, speech or the phrase identical then with current input coding; Sequential search word, speech or phrase backward again, if the code length of current word, speech or phrase is less than the length of the coding of current input, or code length equals the code length of current input, but it is inequality with the coding of current input, or arrival dictionary end, then exit find, be in the buffer queue by the good lookup result of character length series arrangement from small to large; If length violation closes the condition that withdraws from, then with the current word that finds, speech or phrase by number of characters few preceding, number of characters many after principle insert buffer queue, and proceed.
In embodiment, the implementing procedure in this stage as shown in Figure 8:
After entering the electronic dictionary module, at first and carry out initial work, what determine current use is english Chinese dictionary or Chinese-English dictionary, and each inquiry is provided with one by key counter N, N=0.After finishing initial work, enter the master routine circulation, wait for the button input.
After receiving the signal of 5 button buttons that are used for dictionary input, judge by be which button, and note this button corresponding codes.Check this moment and press key counter N,, can directly carry out Dictionary retrieval and handle if N=0 then illustrates the letter of this letter for first input; If N＞0 illustrates that then this letter is not the letter of first input, the back of input coding forms a new coded strings before the coding of this input need being added in, and carries out searching of dictionary again.Before searching, will add 1 by key counter N.
In the dictionary lookup stage, according to the coded strings and the index of input, search and the record coding words offset address identical or relevant, and on screen, show the result who searches with input coding.According to different requirements, search and can adopt dual mode, a kind of is only to search coding word, speech or the phrase identical with current input coding, for example, input coding is " 123 ", is encoded to word, speech or the phrase of " 123 " in then only looking up the dictionary; Another kind is except searching coding word, speech or the phrase identical with current input coding, searching its coding simultaneously is to be other words, speech or the phrase of prefix with the present encoding, for example, input coding is " 123 ", then outside searching all words that are encoded to " 123 ", speech or phrase, also continue to search successively to be encoded to " 123X ", " 123XX ", " 123XXX ", word, speech or phrase, till showing that a full screen or search are less than speech, any one coding in " X " expression " 1 ", " 2 ", " 3 ", " 4 ", " 5 " wherein.First kind of enforcement of searching mode is very simple, as long as in current dictionary, find all words, speech or the phrase identical and show with current input coding, but its associative ability is relatively poor, when certain word or phonetic are longer, the situation of speech might appear can not find in input process, to importer's the bad influence of psychology generation.Present embodiment has adopted second kind to search mode, although this mode implements than first kind and searches slightly complexity of mode, but associative ability is very strong, do not need to import fully word, speech or the phrase that the i.e. association of encoding goes out the needs input under a lot of situations, use easily, computing is also very simple.This searches the enforcement of mode, at first needs to be provided with a buffer queue, and its size can be held word, speech or the phrase that a screen can show at least.The several screen according to the show of word, speech or the phrase that one screen can hold size, Chinese and English font size, the composing when showing, can precompute, for example, to searching of english Chinese dictionary, if the multipotency of a screen shows 10 row, word, speech or the phrase of maximum 4 English of every row, then the size of buffer queue can be held the relevant information of 40 speech at least; To searching of Chinese-English dictionary, if the multipotency of a screen shows 10 row, every row maximum 6 Chinese words, speech or phrases, then the size of buffer queue can be held the relevant information of 60 speech at least.After finishing being provided with of buffer queue, the start address that can at present used dictionary, search word, speech or the phrase identical according to index with current input coding.With this address is starting point, word of sequential search backward, speech or phrase, if current word, the code length of speech or phrase is less than the length of the coding of current input, or code length equals the code length of current input, but it is inequality with the coding of current input, or arrival dictionary end, then exit find, be by character length from small to large series arrangement good lookup result in the buffer queue this moment, otherwise then with the current word that finds, speech or phrase press number of characters few preceding, number of characters many after principle insert buffer queue, and continue above search procedure, till satisfying exit criteria.
Search finish after, lookup result is shown on screen, can push " determining " key and enter the speech stage of selecting when showing the speech that he wants to look into when the user sees on the screen.If system has the button more than 5, can use letter input button in addition to represent " affirmation ", if system has only 5 buttons, then can use the mode of " long pressing " certain key to represent to confirm.
Enter and select speech after the stage, show the cursor select speech to use on the screen, originally 4 in 5 of input alphabet buttons become upper and lower, left and right, select the speech use for the user.Want the speech looked into when the user chooses, and, search the explanation of this speech correspondence, and on screen, show, promptly finish one query by after determining.
In the present embodiment, the user also can want the speech looked into not seeing, but when determining the quite right prerequisite of the input of front, pushes " determining " key and enter the speech stage of selecting, and finds by page turning backward and wants the speech looked into.
In the present embodiment, the hot key that a dictionary switches is set, can under free position, carries out the switching of English-Chinese/Chinese-English dictionary.Import for convenience, present embodiment also is provided with function buttons such as " backspace ", " removing ", and these buttons can use the button beyond the letter input, also can use the method for " long pressing " to realize.
