In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the specific embodiment of the invention is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, in accompanying drawing, only show part related to the present invention but not full content.
Fig. 1 is the process flow diagram of the segmenting method of first embodiment of the invention.This segmenting method is applied to mobile terminal.Wherein, mobile terminal comprises smart mobile phone and panel computer etc.Configurable Chinese Word Segmentation Service device end and at least one participle client in mobile terminal, Chinese Word Segmentation Service device end is exclusively used in and carries out word segmentation processing, also be about to word segmentation processing function package to independently in service process, main cause is to guarantee to only have the copy of a dictionary file in internal memory, thereby the internal memory use amount of the time of running is dropped to minimum.Participle client is mainly used in proposing participle request and obtains word segmentation result, can be any application software client that has word segmentation processing demand.The scheme of the present embodiment is brought in execution by Chinese Word Segmentation Service device, and as shown in Figure 1, described method comprises:
The Chinese Word Segmentation Service device termination of step 110, mobile terminal this locality is received the participle request that carries file destination of the participle client transmission of described mobile terminal this locality.
Particularly, the participle request that carries file destination that the participle client that the Chinese Word Segmentation Service device end on mobile terminal can reception itself sends.Wherein, described participle request comprise following at least one: the participle request of directly calling, by the participle request of C or C++ interface interchange and by the participle request of JAVA interface interchange.Wherein, C or C++ and JAVA are all the programming languages of computer realm.
Particularly, the participle request that carries file destination that Chinese Word Segmentation Service device termination contracture word client sends, can be according to the dictionary of its loading, the algorithm corresponding with the dictionary of loading by file destination, such as, one section of Chinese text, cutting is Chinese word one by one, thereby obtains word segmentation result.
In a preferred implementation of the present embodiment, the participle request that carries file destination that Chinese Word Segmentation Service device termination contracture word client sends in step 110, also comprise: the Chinese Word Segmentation Service device end in mobile terminal, in when operation, start Chinese Word Segmentation Service process, the participle request that carries file destination sending with the participle client of monitoring reception mobile terminal this locality.
Particularly, after mobile terminal starts, before the participle request that carries file destination that Chinese Word Segmentation Service device termination contracture word client sends, Chinese Word Segmentation Service device end starts Chinese Word Segmentation Service process, temporarily do not load the dictionary corresponding with described mobile terminal, thereby reduce the memory headroom that takies mobile terminal.This Chinese Word Segmentation Service process is the detached process that a mobile terminal-opening starts, and when Chinese Word Segmentation Service process is when moving tense, can receive the participle request that participle client sends, and carry out participle calculating.In addition, because the shared memory headroom of Chinese Word Segmentation Service process is very little, and the shared memory headroom of the dictionary corresponding with described mobile terminal will be very large, so enable after Chinese Word Segmentation Service process, do not load immediately the dictionary corresponding with described mobile terminal, and reload described dictionary after only receiving the participle request of participle client.
In another preferred implementation of the present embodiment, the Chinese Word Segmentation Service device termination in step 110 in mobile terminal is received the participle request that carries file destination of the participle client transmission of described mobile terminal this locality, specifically comprises:
Chinese Word Segmentation Service device termination in mobile terminal is received the participle request that the participle client of described mobile terminal this locality is directly called Chinese Word Segmentation Service device end; Or the Chinese Word Segmentation Service device termination in described mobile terminal is received the participle client of described mobile terminal this locality by the participle request of C or C++ interface interchange Chinese Word Segmentation Service device end; Or the Chinese Word Segmentation Service device termination in described mobile terminal is received the participle client of described mobile terminal this locality by the participle request of JAVA interface interchange Chinese Word Segmentation Service device end.
In another preferred implementation of the present embodiment, before in step 120, Chinese Word Segmentation Service device end carries out participle calculating according to the dictionary corresponding with described mobile terminal and a minute word algorithm corresponding to described dictionary to described file destination, also comprise: Chinese Word Segmentation Service device end judges whether to load the described dictionary corresponding with described mobile terminal, if not, the corresponding dictionary of described mobile terminal is loaded in local internal memory.
Particularly, Chinese Word Segmentation Service device end judges whether to load the process of the dictionary corresponding with described mobile terminal.When not having to load the dictionary corresponding with described mobile terminal, load described dictionary, and carry out participle calculating according to described dictionary and a minute word algorithm corresponding to described dictionary, thereby obtain word segmentation result; When loading described corresponding with described mobile terminal dictionary, according to described dictionary and a minute word algorithm corresponding to described dictionary, carry out participle calculating, thereby obtain word segmentation result.
Above-mentioned deterministic process is because the dictionary corresponding with mobile terminal, not forever in stress state, when not receiving the participle request of described participle client transmission within the default time, unloads described dictionary.In other words, mobile terminal is minimum for the internal memory use amount of the time of running is dropped to, the dictionary that the regular unloading of meeting has loaded, thus soar its internal memory taking.
In another preferred implementation of the present embodiment, described segmenting method also comprises: server is chosen and obtained the corresponding dictionary of described mobile terminal according to the hardware configuration of described mobile terminal; Described server pushes to corresponding mobile terminal by described dictionary and stores.Present embodiment has further utilized the external resource of network side server to provide dictionary to mobile terminal.Wherein, the method for choosing dictionary can have a variety of, only describes in embodiments of the present invention wherein a kind of detailed process of method in detail, and other method for optimizing here no longer describe in detail.
Illustrate server below and according to the hardware configuration of mobile terminal, choose the process of dictionary.
(1) server is divided total dictionary, obtains a plurality of dissimilar dictionaries.
Because the general committed memory of participle dictionary using in prior art is all very large, such as, 200MB, therefore cannot be transplanted to large dictionary file like this on mobile terminal, such as, mobile phone, so need to be optimized existing dictionary.Its optimizing process can be:
Chinese vocabulary bank is divided into general word storehouse and the large class of exclusive thesaurus two.General word storehouse is exactly our daily conventional Chinese terms of using, and its size is smaller, can also be compressed to 1-2MB; Exclusive noun can carry out classification segmentation again, such as science and technology, and history, personage, art etc., such as art can be further subdivided into again film, song, literature etc.For the concrete application scenarios of Chinese word segmentation, select the dissimilar dictionary that priority is high, form exclusive noun dictionary, be defined as sub-dictionary here.
In addition, because the hardware configuration of different mobile terminal is different, different mobile terminal has different demands to dictionary file.There are some compared with the read-only memory of the mobile terminal of low side (Read-Only Memory, ROM) less, dictionary file is had to comparatively strict restriction, need to from exclusive noun dictionary, choose and can meet consumers' demand and total size is no more than several dictionaries of certain limitation.The choosing method providing in the embodiment of the present invention is as follows: if total size of the required dictionary of mobile terminal can not surpass M, there is w (1), w (2) ... w (k) is k dictionary altogether, and the file size of each dictionary is m (1), m (2) ... m (k).
2) calculate the initial value of each dictionary.The number of times how dictionary is hit in participle is more, and it is more valuable.Suppose that dictionary w (i) is hit h time in conventional web search participle, altogether carried out the Webpage search participle of H time, the computing formula of the initial value init_value (i) of this dictionary w (i) as shown in Equation (1) so.
Init_value (i)=(h/H) * 100 formula (1)
Wherein, init_value (i) represents the average hit-count of dictionary w (i) in 100 search participles.
3) according to the value of the initial value of each dictionary and participle record calculating dictionary.Wherein, participle record is by collecting the participle record of all participle clients on mobile terminal, thereby calculates the value of dictionary.Suppose that all participle clients have carried out N time participle on mobile terminal, it is inferior that wherein dictionary w (i) has hit n (i), and the computing formula of the value v (i) of dictionary w (i) as shown in Equation (2).
V (i)=100 * [n (i)+β * init_value (i)]/(N+ β * 100) formula (2)
Wherein, β is for regulating parameter, and this value is larger, shows that the influence of initial value is larger.The participle number of times carrying out on mobile terminal when participle client is more, the more approaching statistical figure that this dictionary w (i) is hit by participle under the real scene of mobile terminal of this β value.
4) according to the memory size of the file size of the value of each dictionary and described dictionary and described mobile terminal, choose the dictionary corresponding with mobile terminal.Wherein, the dictionary committed memory amount of selected taking-up is less than total amount of ram of mobile terminal, preferentially selects the value of dictionary large, and the little dictionary of the file of dictionary.In addition, can also adopt greedy algorithm to choose dictionary, choose [v (i)/m (i)] at every turn and be worth maximum dictionary, if the value of [v (i)/m (i)] is close, the preferential little dictionary of m (i) of selecting, until reach the total big or small M of the required dictionary of mobile terminal.
In another preferred implementation of the present embodiment, after loading the dictionary corresponding with mobile terminal, also comprise: when Chinese Word Segmentation Service device end is judged the participle request that does not receive one or more participle clients transmissions within the default time, unload described dictionary.In other words, Chinese Word Segmentation Service device end is minimum for the internal memory use amount of the time of running is dropped to, the dictionary that the regular unloading of meeting has loaded, thus soar its internal memory taking.
The experimental result of segmenting method on the mobile terminal that the embodiment of the present invention provides on Android platform is specially: all sizes of carrying out dynamic base dictionary file are 7MB; The physical memory taking the time of running is 8MB; To the response time of the request of Chinese word segmentation far below 1ms; Accuracy for basic participle is greater than 80%, and the participle accuracy of exclusive noun is greater than 87%.
Therefore, the segmenting method that the embodiment of the present invention provides, the participle request that carries file destination that the Chinese Word Segmentation Service device termination contracture word client of mobile terminal this locality sends, according to the dictionary corresponding with described mobile terminal and a minute word algorithm corresponding to described dictionary, described file destination is carried out to participle calculating, and obtain word segmentation result, realized and on mobile terminal, carried out participle, expanded the application of participle technique.
