Social Proof00:52

Social Proof

24.9K
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

MicroRNAs01:22

MicroRNAs

3.0K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Outliers and Influential Points01:08

Outliers and Influential Points

5.0K
An outlier is an observation of data that does not fit the rest of the data. It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500), while others may indicate that something unusual is happening. Outliers are present far from the least squares line in the vertical direction. They have large "errors," where the "error" or residual is the...

Random Sampling Method01:09

Random Sampling Method

11.8K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest. Among the various sampling methods used by...

Bystander Effect02:09

Bystander Effect

9.5K
The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Area of Science:

  • Computer Science
  • Information Retrieval
  • Artificial Intelligence

Background:

  • Traditional recommender systems for news often rely on user registration, which is uncommon for news websites.
  • Existing methods fail to effectively address latent relationships between news and microblogs, news popularity, and news organization.
  • The need for personalized news recommendations that account for user preferences without explicit registration is significant.

Purpose of the Study:

  • To propose an effective personalized news recommendation method.
  • To address limitations of traditional systems by incorporating microblog data and popularity prediction.
  • To improve the accuracy and diversity of news recommendations in large text datasets.

Main Methods:

  • Developed a news organization method using hybrid classification and clustering.
  • Implemented a sub-class popularity prediction technique.
  • Constructed user profiles based on microblog data and actual user situations.

Main Results:

  • Experimental results show significant improvements in accuracy compared to state-of-the-art approaches.
  • The proposed system demonstrates enhanced diversity in recommendations within mass text data.
  • Comparative analysis on a real-world dataset validates the effectiveness of the new recommendation method.

Conclusions:

  • The proposed personalized news recommendation system effectively leverages microblog user profiles and sub-class popularity prediction.
  • The hybrid approach to news organization and profile construction addresses key limitations of previous methods.
  • The system offers a significant advancement in delivering accurate and diverse news recommendations.
