This blog post aims to\u00a0provide\u00a0commercial and academic understanding towards\u00a0popular recommendation system. Commercially, the recommendation system contributes greatly to the number of views of webpages, it helps viewers to find contents that they’re interested in. Academicly, it is a good study case for understanding how contents in a large repository are discovered and the importance for content discovery tools, how information is stored and retrieved.<\/p>\n

Summerized from paper I read, the recommendation system contributes the repository in the following ways:<\/p>\n

1.\u00a0 Recommendation is one of the most imporant traffic sources of a large repository system. Take Youtube for example, there are several ways to access youtube. People can access through direct visit, Google Search, Mobile applications and Desktop applications. Research shows that over 50% of views are contributed through recommendation. For a large portion of the videos, they’re viewed many times before it is indexed to search engine.<\/p>\n

Commercially, this adds the stickiness of websites therefore users stay on YouTube longer. It results in more advertisement apperance chances and higher advertisement click through times.<\/p>\n

2.\u00a0 The more source is viewed, the more recommendation will be viewed. This means there’s a strong bond between source and recommendation. If the source is popular, the recommendation has a higher chance of becoming popular. This can be used for promotion and control of trend.<\/p>\n

3.\u00a0 Recommendation helps user discover what they like rather than what is popular. Information systems without recommendation usually pop up what is believed to be popular or what they want to show to the users. They plant information to users rather than let them accept it actively. Recommendation induces users\u00a0thru giving users\u00a0options to choose, users could find\u00a0what is provided\u00a0useful for them\u00a0therefore\u00a0users are likely to\u00a0revisit the system again.<\/p>\n
