Internet 2010

At the beginning of eleven o'clock, Meng Xiaoqin called Lu Zhou the leader of the Wechat and Weitou team.

Ren Luzhou remembered that Chen Dongzhuo, the project manager dug from Fetion during the recruitment expansion of WeChat HR in the second half of last year, had some contact with him in his previous work.

"Mr. Road."

"Wait a moment."

Lu Zhou first reviewed and sent the email he had on hand, and then said, "It has been a while since the internal project of Wei Toutiao was established, and I have also read the documents, but I have some doubts about some things, so I want to communicate with you, Brother Zhuo. a bit."

Chen Dongzhuo, "Mr. Lu, tell me."

Lu Zhou, "First of all, the official account and the micro-toutiao are two completely different product forms. Most of the functions of the official account are designed according to the requirements I put forward, and the micro-toutiao is the idea of ​​Lao Cheng himself.

Official accounts are based on user preferences and behaviors, while Wei Toutiao is an automatic match between users and information.

Therefore, although the official account is now included in your group for routine maintenance, you need to distinguish between the two products. "

Chen Dongzhuo, "Understood. At present, we are still in accordance with Cheng Xuyuan's meaning. The work is still mainly based on the public account. Weitou is still in the discussion stage, and the corresponding design and vision are gradually being improved."

Lu Zhou handed Chen Dongzhuo a document, "This is the version I modified on your basis, and the electronic file has also been sent to your mailbox."

Then he went on to say, "The idea of ​​integrating content information into a stream should not be uncommon.

From thousands of degrees screening and inclusion, to blogging and Weibo attention, to the product form in the circle of friends, and even the next micro headlines, the essence is the flow of content information.

Weibo is based on the relationship of attention, and the circle of friends is based on the relationship between reality and friends in WeChat, but in terms of content presentation, its display principles all follow the timeline.

Microtoutiao, on the other hand, needs to add some influencing factors to the time axis, and perform a screening and rearrangement of the entire information flow.

In the whole recommendation model, there will be some quantifiable data, such as user behavior: click-through rate, likes, comment forwarding; user environment data: geographic location, time; popularity characteristics: global, category and topic popularity.

Matching based on content and users is the innovation of Lao Cheng's vision. Of course, that's not to say no one thought of the idea. But there should be not many people who start doing it. "

Chen Dongzhuo nodded slightly, "I can understand Mr. Lu, but in terms of implementation, I think there is a big problem. The first is the initial startup. We need to label and classify the content. Only the training model of the content is ok, we To be able to associate content with users.”

Lu Zhou smiled and said, "You can rest assured. The data source, Dream Valley is provided by someone. In terms of classification, we use hierarchical text classification, such as major categories of technology, sports, and finance, such as sports and then subdivide basketball and football, Subdivided layer by layer.

And you need to continue to refine and granulate it. For example, the lowest level in entertainment should even be specific to people, such as a certain star. The smaller the particle, the higher the degree of identification, and the recommended effect is naturally more ideal.

I think Yang Mi's users should like to have her gossip. "

Chen Dongzhuo, "Then next?"

Lu Zhou, "Since there is a content classification level, naturally the content of the article is input into the system, and the system labels each article with a classification label.

As the content is pushed to the user's eyes, the client can collect the user's behavior, for example, based on his clicks and retention, and then judge his preferences, so that the user tag is also available.

For the initial users, that is to first select the favorite categories, then push articles with high classification popularity, and then further collect user behavior. "

Chen Dongzhuo obviously understood a lot after listening to it, which is much faster than blind flies scurrying around.

He looked a little excited, "I understand Mr. Lu! I'll go down and make arrangements."

Lu Zhou, "Don't worry. Batch computing, currently WeChat or Menggu Cloud can't meet the requirements of real-time analysis, you need to make some separate designs for this. Of course, this part of the needs can be sacrificed appropriately in a short period of time.

As for the algorithm, you can ask Lao Cheng to contact the laboratory. If there are new achievements and progress, you can make some bold attempts. Don't be afraid to make mistakes, just change.

For data problems, I will arrange to connect with you. "

Chen Dongzhuo, "Okay. I'll contact and work first."

After all, this person left Lu Zhou's office in a hurry.

"Hey. Another impatient." Lu Zhou shook his head and smiled.

Easy in words, always troublesome in implementation. Naturally, things cannot be as simple as what Lu Zhou said.

It is like filtering "noise", eliminating clicks with a short stay time, and combating the behavior of headliners; for example, time decay, the weight brought by the earlier click is not static, but requires dynamic changes and weight reduction.

Another example is the problem of batch computing the amount of data. The data analysis carried out by WeChat or Menggu to crack down on some information is an intermittent task, but for Wei Toutiao, it needs to deal with a large number of user behavior analysis every day. In fact, the further the data is, the more it is bound to become. trouble.

Another example is to consider commercialization, the fit between content and advertisements, and some label classification processing is required for advertisements.

However, this was not a chore that Lu Zhou was troubled by, so he would not work too hard. The work that has been done by the WeChat public account is placed there~www.readwn.com~ and Menggu itself also has a series of data and technical support. It is not difficult for Wei Toutiao to succeed, but how far it can be achieved is another matter.

If the team led by Chen Dongzhuo is good enough, by then, Lu Zhou will not mind opening up the WeChat public account and the platform of Wei Toutiao to conduct initial drainage for Wei Toutiao.

This is directly a background release of the content creator of the official account, and the content can be sent to two applications, eliminating the trouble of missing content and creators in the early stage of Weitou.

In the previous life, the so-called content entrepreneurship was seen from the scarf, and from the beginning of the public account, it became popular because of the headlines. Big Fish, Baijia, Penguin, and Sohu are another industry that has squeezed into thousands of companies.

Because WeChat needs to fill some natural deficiencies in the circle of friends and enter into commercialization, the public number Luzhou needs to be adjusted. At this time, Lu Zhou had to go and join in the fun. What's more, Cheng Xuyuan always had an idea about this matter.

"Xiaoqin!"

"Eh!"

"Contact Zhou Da of Zheng Dongzhou Data, and instruct him to connect the data to Brother Lu's laboratory and Chen Dongzhuo. They all know the process."

Meng Xiaoqin wanted to cry but had no tears after listening to it. The Guangnan data center has not finished processing this morning.

"Okay...right now."

Lu Zhou glanced at the time, and it was almost twelve o'clock for this nonsense meal with Chen Dongzhuo, and he had to go back to eat again.
