Reading this book begins with making sense of the characters' relationships, which are centered on the Buendía family and tells the story of the family's prosperity and decline, internal relationships and political struggles, self-mixing and rebirth over the course of a hundred years.

Project management is the process of applying specialized knowledge, skills, tools, and methods to project activities so that the project can achieve or exceed the set needs and expectations within the constraints of limited resources. This diagram provides a comprehensive overview of the 8 components of the project management process and can be used as a generic template for direct application.

algorithm
definition
It refers to a set of instructions or plans based on data analysis and oriented to specific goals based on specific and precise logical operations and implemented using computer programs. As an information technology with wide application and connectivity, algorithm application fields include GPS route planning, content recommendation, attribute matching and disease prediction, etc.
The application of algorithms in the field of news dissemination has broken the traditional news production and dissemination model. Algorithmic news, characterized by algorithm leadership, data support, and autonomous operation, is penetrating into the entire process of news production and dissemination.
Algorithm recommendation
By tracking users' online behavior, algorithms are used to calculate personal characteristics, environmental characteristics and other relevant information, and from this, we can infer the content that users may like.
The algorithm needs to understand and match three characteristics
User characteristics: age of interest, occupation, mobile phone model, reading history, etc.
Environmental characteristics: Make recommendations to users based on environmental characteristics such as time, geographical location, network conditions, weather conditions, etc.
Analyze the content and characteristics of articles through algorithms: including keywords, subject headings, tag popularity, timeliness, etc.
Algorithm recommendation based on user interests is the main distribution method of mobile Internet news, represented by Toutiao, Yidian News, etc.
The positive impact of algorithmically recommended news
News Concept: From “Content is King” to “User First”
Audience status improves, and users become the center of news production and push
News gathering and editing: from “news value” to “user interest”
Collect and organize user data on usage scenarios, usage preferences and interest preferences for news integration and editing. News collection and writing is gradually transformed from being based on news value to being based on user interests. Some scholars believe that this is the transfer of control power from manual editors to intelligent algorithms.
News push: from traditional “unified push” to “personalized push”
Based on the user's past browsing history, the algorithm recommendation can be used to achieve a dynamic description of the user's portrait, thereby reaching thousands of people, allowing each producer's news to intelligently and accurately match the user, which is expected to better meet the long-tail needs of users. , and can further increase user stickiness and improve communication effects.
News talents: from "acquisition and writing talents" to "all-round technical talents"
Technical talents or all-round talents who are proficient in big data dissemination and even algorithm design have become demand-oriented. In the future, in addition to basic business capabilities such as editing, editing, and commenting, computer technology will also become the focus of demand for news professionals.
News Market: From "Uniform Market" to "Niche Market"
Constructing a niche market is the market space occupied by a small group of customers with similar interests or needs in a larger market segment. In the past, the way news was disseminated was to push news based on the general needs of the public. This information satisfied The information needs of most people in society have ignored the fine division of the market. Nowadays, algorithm recommendations are used for personalized news push, so that the needs of small groups can be greatly satisfied, and the construction of niche markets in the personalized field can be realized.
Negative impact of algorithm recommendations
The contradiction between algorithm recommendation and user privacy leakage
Algorithmic recommendation will lead to the emergence of information cocoons. Users will only accept information that conforms to their own preferences, further strengthening their original inherent preferences, alienating opportunities for collision with other information, and breaking away from social information and experience sharing.
The Balkan effect of the Internet is prominent. Users only receive information that they are interested in, and exclude information that they are not interested in from the information receiving network. Groups with the same interests gather together, forming thick barriers between these interest groups and another group. , over time, society was divided into small compartments, which greatly weakened the functions of the group.
Network groups are polarized. Due to the information cocoon and the Balkan effect of the network, the opportunities for group members to communicate with the outside world are greatly reduced, and the homogeneous characteristics within the group are obvious. There is a tendency for these groups to develop to the extremes of the group. Insults they use against other people or groups who disagree with them
In the attention economy, algorithmic platforms take full advantage of human nature’s curiosity and laziness to push vulgar and entertaining news. Long-tail content that requires users to pay learning costs or high quality is often not welcomed. Gradually, Being marginalized, eventually leading to the lack of headlines about expulsion of good money, the truth behind the party, and endless news
Algorithmic Media Governance Mechanism
Platform social responsibility at the technical level
Legal policy ethics at the institutional level
User algorithm literacy at the social level
Algorithm recommendation and online public opinion
positive influence
Accurate portrait, aware of behavior
Precise distribution, personalized communication
Accurate feedback and insights
Accurate correction and reshaping of tendencies
negative impacts
The main gatekeeper leaves the market, and the value-oriented quality is insufficient.
The echo chamber phenomenon is serious and it is difficult to build consensus
The spiral effect of silence appears, and the online public opinion field is distorted
algorithmic discrimination
Performance
price
gender
Race
feature
More accurate
More diverse
More one-sided (human society’s judgment of individuals is usually comprehensive and dynamic, but algorithms cannot obtain and process all user data)
more hidden
