no. 1 example

[0025] figure 1 It is a flowchart of a processing method for describing attribute data provided by the first embodiment of the present invention. The method of this embodiment can be executed by a processing device for describing attribute data, and the device can be implemented by means of hardware and / or software. And it can generally be integrated in a server for providing processing services describing attribute data.

[0026] The method of this embodiment specifically includes:

[0027] 110. Using the descriptive attribute of the target object as a first node, and using at least two first index values ​​as a second node, generate an attribute index parameter pair.

[0028] The target objects are objects that can satisfy the same or similar functions and have the same or part of the same attribute values ​​describing attributes, that is, objects that need to be classified into types in this embodiment. For example, objects such as houses, mobile phones, home appliances, ...

[0048] figure 2 It is a flow chart describing a method for processing attribute data according to the second embodiment of the present invention. This embodiment is optimized on the basis of the above embodiments. In this embodiment, the descriptive attribute of the target object is used as the first node, and at least two first index values ​​are used as the second node, and the generated attribute index parameter pair is optimized as follows: collecting at least two attribute values ​​describing attributes of the target to form a point set of the first node; setting at least two first index values ​​to form a point set of the second node; adopting the form of a heterogeneous bipartite graph, generating the attribute index parameter pair based on the point sets of the first node and the second node;

[0049] Further, according to the set of attribute index vectors, classify and optimize the target object as follows: calculate the similarity between each target object based ...

[0066] Figure 4 It is a flow chart describing a method for processing attribute data according to the third embodiment of the present invention. This embodiment is optimized based on the above-mentioned embodiments. In this embodiment, preferably, the first index is optimized as sales time, and the second index is optimized as sales quantity;

[0067] At the same time, the target object is optimized as a house, and the description attribute is optimized to include at least one of the following: the administrative division where the house is located, the price of the house, the neighborhood where the house is located, the floor where the house is located, the building area of ​​the house, and the time when the house was built.

[0068] Correspondingly, the method of this embodiment includes:

[0069] 410. Using the descriptive attribute of the house as the first node and at least two first selling times as the second node, generate an attribute index parameter pair.

Abstract

An embodiment of the invention provides a processing method and a processing device for description attribute data. The method includes taking description attributes of a target object as a first node, taking at least two first index values as a second node, and generating attribute index parameter pairs; taking second index statistic data matched with the attribute index parameter pairs as weights of the attribute index parameter pairs to generate an attribute index vector set; performing type division on the target object according to the attribute index vector set. The processing method and the processing device have the advantages that the attribute index vector set capable of expressing corresponding relationships between the description attributes of the target object and the first index values is created, accurate type division of the target object is achieved on the basis of the attribute index vector set, and accordingly, people's increasing requirements on individualized and accurate target object type division are met.

Description

technical field [0001] The embodiments of the present invention relate to data processing technologies, and in particular to a method and device for processing description attribute data. Background technique [0002] In recent years, with the vigorous development of Internet technology, many online housing transaction websites have appeared, on these websites, customers can publish their own house source sales information and find their desired house source. For these online housing websites and publishers of housing information, an extremely important requirement is to estimate the sale time of the relevant houses in advance (that is: how long will it take for the published listings to be sold), this sale time is called in economics Days on Market (DOM), this parameter is an important indicator used to measure the activity of housing, and it is also a reference indicator with important economic value. [0003] In view of the above indicators, the research direction of the...
