Description
Technical field
The present invention relates to a kind of source of houses polymerizations based on the similar calculating of various dimensions information.
Background technique
The official website of current each brokerage firm is only capable of showing the own source of houses, and some platforms also only simply grab other
The source of houses of platform or brokerage firm is shown as former state.As for the historical price and condition managing in house, now in each platform base
Sheet or blank, because brokerage firm is not intended to let the user know that a house is to appreciate or make a price reduction.
With regard to information provided by current platform and brokerage firm, if house purchaser wonders that a house is managed at more
The listed information of company needs to multiple brokerage firms or platform to go to compare, and user does not know about some city on earth yet
How many brokerage firm of family may have this house.
Summary of the invention
To overcome the shortcomings of existing technologies, the present invention provides a kind of source of houses polymerization side based on the similar calculating of various dimensions information
Method, the technical scheme is that
A kind of source of houses polymerization based on the similar calculating of various dimensions information, comprising the following steps:
The source of houses of step (1), each platform of crawl or brokerage firm, cleans information of real estate, it is serious to filter out loss of learning
And the doubtful false repetition source of houses；
Whether step (2), the source of houses of the multiple platforms of identification belong to the same suite of rooms；
The polymerization of step (3), the multi-platform source of houses carries out benchmark and selects；
Step (4), source of houses polymerization accuracy and coverage rate detect；
Step (5), the source of houses will record history lists in the history restocking of each platform, rise in price, price reduction information, show a source of houses
In the life cycle of each platform of the whole network.
The step (2) specifically:
Entry criteria: when an information of real estate comes, first finding all same cells of database, with total floor, same to room, and same floor
The house in section meets entry criteria to carry out similar weight calculation, and weight calculation meets the value attributes such as condition and key not
With number less than 2, it is determined as that the same set of source of houses is polymerize；
Wherein, in different channel informations of real estate, the cell name of same cells might have difference, but cell ID be it is identical,
It is known that whether belong to the same cell by comparing cell ID;The cell name of different channels and the corresponding relationship of cell ID are
Merge foundation with name similarity by cell geographical location；
The step (3) specifically: when certain set source of houses of two channels condenses together, higher channel priority is base
Standard, when the source of houses of third channel and two sources of houses meet polymerizing condition, and third channel priority is higher, then third is a
On the basis of the adjustment of the channel source of houses；Specific polymerization are as follows:
By the area of the source of houses, price, room, floor multidimensional characteristic is abstracted as the feature vector input of (x1, x2 ..., xn): sample
This collection D=(x1, x2 ..., xn), the generating mode of similar matrix, the dimension k after dimensionality reduction1, dimension k after cluster2, output:
Cluster division C (c1, c2 ... ck2)；
1) the similar matrix S of sample is constructed according to the generating mode of the similar matrix of input；
2) adjacency matrix W, building degree matrix D are constructed according to similar matrix S；
3) Laplacian Matrix L is calculated；
4) the Laplacian Matrix D after building standardization−1/2LD−1/2；
5) D is calculated−1/2LD−1/2The smallest corresponding feature vector f of k1 characteristic value institute；
6) matrix by rows of corresponding feature vector f composition is standardized, finally forms n × k1The eigenmatrix F of dimension；
7) to every a line in F as a k1The sample of dimension, total n sample, is clustered with the clustering method of input, cluster
Dimension is k2；
8) obtain cluster divide C (c1, c2 ... ck2)；By above-mentioned algorithm, the polymerization of the identical source of houses of different channels is realized.
The step (4) specifically: by inspecting the source of houses in polymerization by random samples, judge whether to be the same set of source of houses,
If it is not, then adjusting the accidentally combined source of houses；
Unpolymerized source of houses coverage rate detected, filter out it is doubtful should polymerize, decide whether to polymerize, if should,
Then adjust the unpolymerized source of houses.
The invention has the advantages that merging the data of the whole network, information of real estate more comprehensively, converges historical data, and transverse and longitudinal is comprehensive
Understand a source of houses in the whole network history various states till now and price trend, a key can contact interested brokerage firm and
Broker greatly improves user and looks for room efficiency.
