For the ease of skilled in the art realises that the application application scenarios, this application provides a kind of temperature calculate be System.It referring to Fig. 1, specifically includes: processing equipment 100 and the multiple data sources 200 being connected with the processing equipment.
It is just of practical significance it is understood that being ranked up in practical situations to same category object, i.e., to video Each video of classification is ranked up, each song of song classification is ranked up etc..Multiple data sources in the application It can be that the source of same category object is provided.For example, the video website of video is provided, alternatively, providing the music website of song Etc..
On the basis of the temperature computing system that Fig. 1 is provided, according to one embodiment of the application, a kind of determination is provided The method of object temperature.As shown in Fig. 2, specifically includes the following steps:
Step S201: processing equipment 100 determines the temperature of each object in each data source.
In order to realize the purpose of all object order lists in each data source of determining same category, inventor moving party Case: merging the object of same category of each data source, obtains the temperature of all objects in same category.For this purpose, firstly the need of Determine the temperature of each object in each data source.
It may comprise steps of according to one embodiment provided by the present application referring to Fig. 3:
Step S2011: processing equipment 100 obtains the object information of multiple objects in each data source;Wherein, described right Image information includes the attribute value of multiple preset attributes and each preset attribute.
Processing equipment 100 can predefine multiple preset attributes for computing object temperature, for example, broadcasting time, Broadcasting number, collection number, searching times etc..
It is understood that each data source can count the attribute value of some attributes.Processing equipment 100 and each data source With data connection, so processing equipment 100 can use the object mark that crawler mode obtains each object from each data source Know, and, the attribute value of multiple preset attributes of each object.
Each data source may not statistical disposition equipment setting each preset attribute attribute value.Therefore, when one In the case that data source does not count the attribute value of a preset attribute, the attribute of the preset attribute of all objects in the data source Value is null value.
Processing equipment 100 is that data source identification is arranged in each data source, multiple object informations in obtaining each data source Afterwards, by the storage corresponding with each data source identification of multiple object informations of each data source.
Referring to table 1, the example of multiple object informations of each data source is stored for processing equipment 100.
Table 1
Optionally, the meeting of processing equipment 100 carries out data cleansing to multiple object informations of each data source, each to guarantee The rationalization of multiple object informations in data source.Carrying out cleaning to data may include:
First, suppressing exception attribute value.Having some attribute values in each data source may be exceptional value, and therefore, judgement is each Whether a attribute value is in preset zone of reasonableness, if not in suppressing exception attribute value.
Second, the data format of attribute value is standardized.Due to the data format disunity of each data source, in order to Convenient for subsequent processing, the data format of each attribute value can be carried out to unification.
Third deletes redundant data value.Some data sources in order to protect data, may back up data.This reality It applies regular meeting and deletes redundant data value.
It can also include other contents, herein not it is understood that being cleaned to the object information of each data source It enumerates again.
Step S2012: processing equipment 100 is that each data source determines temperature attribute in multiple preset attributes respectively.
Each data source has the attribute for computing object temperature originally, and some is using broadcasting time as computing object The temperature attribute of temperature, some for that will play temperature attribute of the number as computing object temperature, make for that will collect number by some For computing object temperature attribute, etc..
Therefore, processing equipment 100 can redefine temperature attribute for each data source, to make each data source determine heat The index of degree attribute is unified (index is unified, but the temperature attribute for determining temperature can be different).
The application provides the two indices for determining temperature attribute:
First index: the minimum preset attribute of null value rate.
By taking a preset attribute of a data source as an example, processing equipment 100 can count the preset attribute in the data source In do not have data value (null value) object number, and, all object numbers in the data source, then calculate both quotient Quotient, is determined as the null value rate of the preset attribute by value.
The null value rate of one preset attribute is lower, indicates that the number of objects in the preset attribute with attribute value is more.Make The object temperature of more object can be calculated with the preset attribute computing object temperature.
Second index: the highest attribute of the uniformity.
By taking a preset attribute of a data source as an example, processing equipment 100 can each preset attribute minimum value with Several grades are set between maximum value.Processing equipment 100 can distinguish the number of objects that statistical attribute value is located at each grade.
If the number of objects in each grade more tends to be identical, the uniformity is higher.
In this step, processing equipment 100 can calculate the null value rate of each preset attribute in each data source and each pre- If the uniformity of attribute;Then, null value rate in each data source is greater than the first preset value and the uniformity is greater than the second preset value Preset attribute, be determined as the temperature attribute of each data source.
Wherein, the first preset value and the second preset value are respectively preset data value, and specific data value can basis Actual conditions specifically determine, it is not limited here.
Step S2013: by the corresponding hot value of temperature attribute of each object in each data source, it is determined as each object Temperature.
Fig. 2 is returned to, enter step S202: processing equipment 100 is standardized the temperature of object in multiple data sources. That is, being standardized acquisition standard hot value to the temperature of each object in each data source respectively, the standard hot of object is utilized Original hot value of angle value upgating object.
Since the object information in each data source is not quite similar, so, it is used to calculate heat based on what identical index determined The temperature attribute of degree is also not quite similar.Some data sources are using broadcasting time as temperature attribute, and some data sources are using use Broadcasting frequency is as temperature attribute, etc..
Since the attribute for being used for computing object temperature in each data source is inconsistent, so the object temperature of each data source Without comparativity.Therefore, can the object temperature to each data source be standardized.
The present embodiment can be standardized the object temperature of each data source using deviation standardization.Referring to fig. 4, have Body process may include:
Step S2021: maximum hot value and minimum hot value are determined in each data source.
In all objects that each data source is included, each object temperature is ranked up, obtains maximum hot value With minimum hot value.
Step S2022: the first difference of the original hot value of computing object and minimum hot value, and, calculate the maximum Second difference of hot value and the minimum hot value, by the quotient of first difference and second difference, as object Standard hot value.
Step S2023: original hot value of the standard hot value upgating object is utilized.
Present embodiments provide a kind of mode of data normalization, it is to be understood that also there are many standardize to data Mode, such as: such as extremum method, standard deviation method, tri linear method, the distribution of half normality will not enumerate herein.To data The specific implementation procedure being standardized has been mature technology, and details are not described herein.
It is then returned to Fig. 2, enters step S203: duplicate removal merging is carried out to multiple same objects, merges multiple numbers to obtain According to the temperature of multiple duplicate removal residue objects and multiple duplicate removal residue objects behind source.
After being standardized to each object temperature in each data source, the object of each data source can be merged. Since an object can reside in multiple data sources (for example, comprising same song in multiple music websites), so The case where multiple data sources include same object will necessarily be encountered.
According to one embodiment of the application, referring to Fig. 5, the implementation procedure of this step includes:
Step S2031: during merging multiple data sources, calculating the similarity in multiple data sources between object, will Multiple same objects that similarity is greater than preset threshold form object set, to obtain multiple object sets.
Object information includes the index of object similarity, may include: program abstract, creator, creation company, issue date The indexs such as phase, region, languages.For an object of a data source, based on index of similarity computing object and other data The similarity of each object in source.
Then, multiple objects of default similarity will be greater than in other data sources with the similarity of the object, be determined as with The object is same object.Same object in each data source can form an object set, which includes multiple phases Same object.
It is understood that the object except object set, there is no the object of same object in each data source.
Step S2032: duplicate removal is carried out to each object set, it is right to merge the duplicate removal residue that each object set only retains As.
Since object set includes multiple same objects, each object is identical but object temperature is not quite similar.Therefore, Ke Yitong The temperature of one same object.
The mode of unified same object temperature may include: that temperature maximum value in object set is determined as object after reunification Temperature, alternatively, temperature average value in object set is determined as object temperature after reunification, etc..
For each object set, duplicate removal is carried out to object set and only retains the extra object of object deletion.In object set The object of reservation is known as duplicate removal residue object, and the hot value of duplicate removal residue object is hot value after reunification.
Step S2033: the temperature of multiple duplicate removal residue objects and multiple duplicate removal residue objects is obtained.
During merging multiple data sources, after executing deduplication operation to object set, merges each object set and only protect The duplicate removal residue object stayed obtains all objects in same category data source.
Be then returned to Fig. 2, enter step S204: processing equipment 100 holds the multiple duplicate removal residue object according to temperature Row sorting operation.
Step S205: processing equipment 100 obtains ranking results after executing sorting operation, and sends ranking results to multiple Data source.
Step S206: multiple 200 sources of data receive and show ranking results.
