Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of an embodiment of the method for result for retrieval of the present invention sequence;
Fig. 2 is the structural representation of an embodiment of the device of result for retrieval of the present invention sequence.
Embodiment
As shown in Figure 1, Fig. 1 is the schematic flow sheet of an embodiment of the method for result for retrieval of the present invention sequence.In the present embodiment, the method for result for retrieval sequence comprises:
101, receive user to the selection of each retrieval service type, wherein, described each retrieval service type has corresponding sequence template respectively.
In the present embodiment, in search engine, store at least two kinds of retrieval service types, and the sequence template corresponding to each retrieval service type.Concrete, the weight that in sequence template, definition has at least one field and this at least one field shared when calculating the putting in order of result for retrieval respectively.Certainly, above are only the citing to sequence template, order module also can be comprise other guide, and this is not restricted.
Wherein, each retrieval service type and sequence template corresponding are respectively search engine default setting.
Optionally, in the present embodiment, search engine also receive user to retrieval service type and/or sequence masterplate setting.
For example, be by receiving in scene that the input of user arranges in sequence template, search engine arranges sequence template by receiving user to the weight of the field in sequence template and this field.When accepting user to the arranging of the weight of field, search engine specifically receives the weighted value of user's input; Or search engine is previously provided with different stage, the wherein corresponding preset weight of each rank, search engine arranges the weight of field by receiving the selection of user to rank.Such as, search engine is previously provided with general, important, extremely important three kinds of ranks, and the corresponding respectively weight of these three kinds of ranks is followed successively by 20%, 30%, 50%.Certainly, above are only citing, do not limit.
Search engine receives user to after the selection of wherein a kind of retrieval service type, receive user to the selection of another kind of retrieval service type before, all according to the sequence template that the retrieval service type of this selection is corresponding, result for retrieval is sorted.
102, retrieval string is obtained.
Concrete, search engine obtains retrieval string by receiving the input of user in frame retrieval.
103, corresponding result for retrieval is obtained according to described retrieval string.
In the present embodiment, the retrieval string that search engine can adopt webpage capture technology to input based on user obtains corresponding some result for retrieval, and this result for retrieval generally presents with the form of URL.
104, corresponding according to the retrieval service type of described selection sequence template sorts to each result for retrieval.
Search engine, when grabbing each result for retrieval, calculates the sequence coefficient of this result for retrieval according to the field in sequence template and the weight of field, wherein, sequence coefficient is higher, then the display of result for retrieval is more forward.
For example, in the scene of the weight having at least one field and this at least one field shared when calculating the putting in order of result for retrieval respectively in definition in template of sorting, search engine is when calculating the sequence coefficient of each result for retrieval, first retrieval string and the matching degree of this result for retrieval in each field is calculated, then the weight of each field is adopted to be weighted summation, using the sequence coefficient of this summed result as this result for retrieval to the matching degree of retrieval string in each field.When the coefficient that sorts is higher, the sequence of this result for retrieval is more forward.
Wherein, retrieval string and the matching degree of result for retrieval in each field, can refer to the text relevant of retrieval string and result for retrieval.
Such as, retrieval service type comprises information class, and the field in the sequence template that described information class retrieval service is corresponding comprises following at least one: title, text, summary, source, label, channel, deliver time, news type.Optionally, in the template that sorts, the weight of field " title " and/or field " summary " is greater than the weight of field " text ".
Again such as, retrieval service type comprises novel class, and the field in the sequence template that described novel class retrieval service is corresponding comprises following at least one: title, title, author, classification, temperature.Optionally, in sequence template, the weight of field " title " is greater than the weight of field " author ", or the weight of field " title " is greater than the weight of field " author ".
Wherein, retrieval string and the matching degree of result for retrieval in each field, also can refer to the authority of result for retrieval.
Such as, retrieval service type comprises application class, and the field in the sequence template that described application class retrieval service is corresponding comprises following at least one: the description of apply names, application another name, developer's name, application program, download, installation amount, star scoring number.Optionally, in the template that sorts, the weight of the description of field " apply names " and/or field " application program " is greater than the weight of field " application another name " and/or field " developer's name ".Wherein, developer's name comprises name or this Develop Application System company of this Develop Application System person.
In the present embodiment, different retrieval service types has corresponding sequence template respectively; By receiving user to the selection of each retrieval service type, the sequence template corresponding according to the retrieval service type of described selection sorts to each result for retrieval, makes the sequence of result for retrieval more meet the requirement of different retrieval service.
