Gree air-conditioning in the Oaks Jingdong purchase index (reptile case - gossip)

This some time ago a "report Oaks Gree air quality" thing, then look at these two shops Jingdong, I feel very interesting, looking to find Oaks optional finger

The number is much higher. So, try to climb it and see, practiced hand small demo, this article is to introduce them to crawl data, and data on these relatively inaccurate, himself

the opinion of.

Data Sources

The following data is how come it? They want to practice simple reptiles themselves up drops, you can see details This section describes !

Because of a series, there are several models (the size of the number of horses), but this series is not very different from the index of purchase, do not climb.

Today, just climb, warming up.

Some explanation of the data

Data includes, spk (commodity Jingdong internal serial number), product title, price, website, creation time, the number of comments, the purchase index, purchase shops.

Since the data does not give Jingdong sales of goods, I can only be replaced by the number of comments, based on previous experience of doing SEM, comments are estimated between 1-2%, anyway, I crawled to buy sales index also lacks impact .

Because not every commodity has to buy the index, the number of comments is below 100, the price of the missing, I have deleted, about half of the product (the total number of comments around 100,000).
Are the top 10 data, I turned a bit, beginning on page 5, the number of comments very much.
Data, the total number of comments, Gree 1.7 million +, Oaks 1 million +. Just to say, a category in which a model (the number of horses size) information, therefore, is not accurate, but also reference value.

Oaks optional index is relatively high point

Average score Oaks Gree 5.959 6.641
