Embodiment
The invention provides a kind of feedback display method of network dictionary retrieve results, its core concept is: 1) server obtains the retrieval request of client, obtains the data content of described retrieval request correspondence according to the search mechanism that presets; 2) will not have the constraint or the data content of incidence relation and be divided into data block, the algorithm that employing can the order coding/decoding compresses respectively, also comprises the label that identifies this data block starting and ending position in each data block; To send after each data block splicing; 3) client is resolved the data block that receives, if be resolved to described label, then show and has resolved the data content that finishes.
As specific embodiment, implementation of the present invention is described when looking into speech with the network electronic dictionary below.According to above-mentioned core concept, the core of present embodiment is: the user when searching word, disposable taking-up search key all explanatory contents in selected or several dictionaries; Because the retrieval dictionary-like data is had relatively high expectations to feedback speed, and then in transmission course, data arrive after the client part, promptly show.
For realizing above-mentioned functions, the present invention mainly comprises the content of three aspects: the setting of data retrieval logic and interface; The tissue of transmission data; Client output.Specify the implementation method of above-mentioned three aspects below.
The setting of data retrieval logic and interface.Carry out refinement and classification by explain information when dictionary is put in order to entry, and then the information of difference retrieval frequency is separated from the data bottom, while is in conjunction with the mode classification of actual user's use habit, help filtering out the data of the real needs of user, thereby reduce data traffic redundant and waste.
Data engine provides the ability of systematic searching entry explain information from the storage organization of bottom, the interface of an entry of disposable retrieval explain information in many dictionaries is provided, and corresponding to every dictionary, can also be provided with and independently retrieve the classification mask separately, be used for informing that data retrieval engine extracts the explain information of retrieval entry in the classification of current dictionary.The retrieval of data is provided with the following form of interface:
int?SetKey(CibaData&?Key)；
The word that needs inquiry is set; Wherein, Key is the data object that comprises configuration information.Rreturn value 0 is for being provided with success, and non-0 value is for being provided with failure.
int?AddDict(int?DictIndex，unsigned?int?DictSearchMask)；
The dictionary that adds a desire retrieval; Wherein DictIndex is for adding the call number of dictionary, DictSearchMask is the classified inquiry sign of 32 signless integers, each is corresponding to the explanation item of classifying of word, and described classified inquiry sign and word classification explain that the corresponding relation of item can define voluntarily; This place value is 1 o'clock, and expression this classification of inquiry (whether should explain following a little) is explained, is 0 o'clock, and expression is not inquired about this classification and explained; When function int AddDict rreturn value was 0, the dictionary of expression desire retrieval added successfully, and during non-0 value, the dictionary interpolation process appearance of expression desire retrieval unusually.
int?DoSearch(CibaData**Exp)；
Start inquiry; Query interface carries out data retrieval according to the desire looking up words of above-mentioned setting with the classified inquiry sign of inquiring about the dictionary tabulation and every dictionary is set, and result for retrieval is returned; Ignore the dictionary that do not have return results (do not contain in the dictionary that is retrieved looked into key word should or the classification information total length of looking into be 0); Wherein, Exp if the return results pointer is NULL, then inquires about failure for pointing to the pointer of inquiry return results.Rreturn value 0 is for running succeeded, and non-0 value is unusual for occurring in the query script, and Query Result can not use; Wherein, CibaData is the result for retrieval corresponding with key word, and its organization definition is as follows:
struct?CibaData{
char*?data；
int?len；}；
By this organization definition as can be known, in the present embodiment, disposable retrieval is also obtained all data contents corresponding with definite key word in corresponding dictionary and corresponding classification, constitutes the result for retrieval of this key word.
On the basis of above-mentioned data retrieval logic and interface setting, with reference to Fig. 1, promptly performing step 11: server obtains the retrieval request of client, obtains the data content of described retrieval request correspondence according to the search mechanism that presets.Its concrete steps comprise:
1) key word that needs inquiry is set;
2) dictionary of required inquiry is set, is specially the service marking bit representation and does not have this dictionary whether to need to be retrieved, for example: 1100001110; Wherein each is represented a dictionary respectively, and value is 1 o'clock, and the pairing dictionary of expression this zone bit of inquiry is 0 o'clock, and the dictionary of this zone bit correspondence is not inquired about in expression;
3) according to 1), 2) setting, carry out search operaqtion, and return result for retrieval.
In sum, (search key after the upper layer network service receives a query requests, perhaps further comprise attached retrieval options), the classified information retrieval mask of the entry of needs retrievals and all dictinary informations that are retrieved and corresponding dictionary is set in the middle of the Retrieval Interface, and disposable then execution retrieving also obtains desired data.
The tissue of transmission data.Purpose is that the data organization with result for retrieval becomes the data mode that the streaming that can carry out order reads, so that after the data arrival client, client whenever receives a part of data and just analysis result can be shown, and decode again after will complete data packet all not obtaining and show, and then can satisfy the user looks into the speech feedback speed to network requirement, and client meets normal reading habit with from first to last order demonstration of Query Result.With reference to Fig. 1, the core of transmission data organization is a step 12: the single explanation item with definite key word is that dividing elements becomes data block, at least one of key word can be explained that item number is according to handling as a data block, the employing algorithm of coding/decoding is in proper order compressed each data block respectively, also comprises the label that identifies this data block starting and ending position in each data block; To send after each data block splicing.
Employing can order encrypt/decrypt and compression/de-compression the block encoding means, make in the streaming decoding of supporting data, the data corruption of contingency to be limited in the individual data piece, avoid because the related overall data that is produced of encrypting is destroyed; And, employing is by built-in outer extend markup language (XML) format description data block information, comprise that the data block start/end is put, dictionary type, compression sign etc., make each independently data block all possess the self-description ability, one-piece construction has good fault-tolerant ability, and then, the loss of data of the contingency that occurs in any position and destroying within the parent data block of the data block that can both be limited in going wrong, client can further be selected to abandon error burst and continue follow-up parsing and show or retrieve again.
With reference to Fig. 2, this figure is the output data form of single mandate dictionary.As shown in the figure, single dictionary explains that the block data structure of item requires the compressed text data block for the decompression algorithm of coupling the self-described ability to be arranged.Each fields function is as follows shown in the figure:
Data block length: count in the shared space on storer of whole data block shown in the figure, comprises 4 bytes that the data block length data take self;
Dictionary index (4 byte): the source of sign current data block, the corresponding relation of dictionary index and dictionary type is mainly used in client and uses, division foundation as different language classification dictionary, usually, described corresponding relation is once determining no longer change, when needing to change, revise dictionary context initialization configuration file, and upgrade synchronously by upgrade function notice client;
Compression sign (4 byte): be used to identify the compress mode that this data block adopts, make client can adopt appropriate decompression algorithm handle current data block with word classification decryption, The data in every dictionary is with a kind of compression method, under the normal condition, the type of dictionary has influence on the compress mode that is adopted, but does not have strict restriction relation; Compressed and decompressed algorithm was determined before the dictionary compiling, and is provided client to use with the storehouse form;
Compressed text data: be the classification decryption that from current dictionary, inquires according to user's request; In the present embodiment, query script only will be inquired about the classification decryption piece that obtains and do simple concatenation, and the decompression algorithm that requires to use can be discerned the initial of each data segment and ending, to guarantee correct spliced data segment is correctly reduced.
All include the XML label of describing self class categories in each compressed text data block, whole spliced compressed text data block will form the standard XML document after decompressing, and then will be resolved by client again.

Last example is the second class explain information corresponding to a certain key word, wherein＜and wordexp_type2〉with＜/wordexp_type2〉identify the initial of these second class explain information data respectively and end up; And, according to label＜wordexp_type2_1 〉,＜/wordexp_type2_1〉and label＜wordexp_type2_2,＜/wordexp_type2_2〉as can be known, further comprised two subclass explain informations in this second class explain information.
With reference to Fig. 3, this figure is the output data form of the whole Query Result of server.For each Query Result is not empty dictionary, and the compressed text data block that single this dictionary enquiry obtains is carried out simple concatenation as final result data.The result for retrieval data are actually with the classification of entry in a dictionary and explain that piece is the serial data stream of base unit; For each compressed text data block, employing can be decoded in proper order and be conciliate code and cryptographic algorithm, as Bzip compression algorithm and des encryption algorithm, because the decoding decrypted result is the Unicode word string, can on to greatest extent, guarantee the self-described ability of data with 0 sign and the interblock segmentation symbol that is worth as end of data block of two bytes.
Client output.Its core is to realize step 13 shown in Figure 1: client is resolved the data block that receives, if be resolved to described label, then show and has resolved the data content that finishes.
When server is finished retrieval, the data content that is about to obtain feeds back to client by streaming Socket (as TCP) in above-mentioned data organization mode; Client is after receiving the data of first byte, get started and resolve, obtain after the data of 12 bytes at most, client promptly can begin the data that arrive are at first carried out decode operation, whenever being resolved to an XML label, client is about to it and shows on user interface, so constantly carries out, the client display effect is the entry classification explain information that constantly appends, and finishes up to all Data Receiving.
If client is found error in data when resolution data, as: not to the XML end-tag promptly meet the end of data, character string of occurring discerning, XML label disappearance or the like, then continue to seek backward the XML label of the data block of discernible and Error Location data block parent data block peer and proceed to resolve, and then avoid making whole result for retrieval to cancel; When having only data corruption extremely can't resolve fully, client just need resubmit retrieval request.
More than be the full implementation example of the method for the invention, on the said method basis, the present invention can further carry out the setting that retrieval request produces logic according to customer demand in actual applications.For example: the 1) application of feedback speed being had relatively high expectations for this class of screen word-selecting, each user's retrieval request at first causes sending the essential information retrieval request, and obtain user's corresponding data content and show feedback information according to the feedback display method of the above-mentioned network dictionary retrieve results that provides, simultaneously, provide the user to launch the link of explaining in detail, and the detailed explain information of look ahead on the backstage corresponding word and dictionary; 2), only ruined classification and dictinary information are carried out the backstage and refetch, and need not to retrieve fully again for ruined data; 3) look into this class of speech for the less demanding application of feedback speed for manual, disposablely fetch all user's specific datas, and simultaneously remainder data is carried out the backstage and look ahead.
In addition, the present invention also can further expand or adopt other specific implementations, for example:
1) the present invention can be used in combination dynamic local cache technology, and the query history result is carried out the recessiveness buffering, can reduce server real work amount.
2) among the present invention, server can be according to statistics, the data that the retrieval frequency are higher than the preset gate limit value split out the front end buffering that is used as server separately, and all retrieval request that only relate to data in the front end buffering all do not enter the master data base retrieval, to save the retrieve resources of master data base.
3) organize the stage in output data, can organize again the Query Result data, for example in many dictionaries during data query, based on data organization method of the present invention, to be organized in the front end of whole data segment in every dictionary separately about the essential information of the key word that is retrieved, all the other detailed explain informations are then followed after described essential information.The method can satisfy user's demand with less relatively retrieval number of times under some application conditions.
Corresponding with said method, the present invention also provides a kind of webserver, is used to realize the network data library searching, and with reference to Fig. 4, this server mainly comprises: I/O unit 41, query parse unit 42, query unit 43, and data organization unit 44;
