How Personalized
Recommender System Influence Users’ Attitude?
Feng, Yuan (1155081930)
Nowadays, this is no
longer the “geeks time” when people are sensitive to information and always
require more message. What most users want to do now, is just migrate the real
life into Internet, they show far more interest in SNS friend speaking than the
latest technology trends. As the composition of Internet users changing, for
Internet product, service object shall change accordingly. And that’s may be
one reason why the personalized recommendation emerged and mattered.
From Affective to Conative
and Cognitive
Customer’s attitude can
be influenced by multiple factors, as what we’ve learned in last few classes,
the mental position a person takes towards a topic, person, or an event that
influences an individual’s feelings, perceptions, learning processes, and
behaviors. There exist three steps or dimensions in this field, for
personalized recommender system, this function basically follows the sequence
from affective to conative and cognitive.
The strongest proof is
what you may already have discovered that when you open a app, it used to contain
various types of information, while now is full of one or a few specific types,
usually entertainment gossip, or funny making jokes of socialization. Like the daily
recommendation songs in your Netease cloud music APP (see Figure 1), and
“something that you may interested” part in Taobao, usually listing something
that you searched before or just bought the similar products. These are all the
very achievement of personalized recommendation system.

recommendation
Generally speaking, personalized
recommendation based on user characteristics and preferences, through the
collection, analysis and define its users’ behavior in history, understand what
kind of person the user is, and what are their behavior preference, what they buy,
share, produce, or interactive feedback and so on. Finally, it will understand
and obtain user preferences that comply with the rules of the platform
features, therefore recommend information of interest to users.
Besides, target customer
segmentation is also important, as the view of demographic aspect, different age
and work group of consumers may show different curiosity and acceptance level
towards personalized recommendation, younger generations may feel less offend
when they realize their behaviors have been “observing and calculated” their
behaviors, and hence grow interest in one specific APP, while white collar may
find recommended interesting news truly help relief the stress since all-day
work really don’t need extra serious common information.
Five Key Elements of
Personalized Recommendation
However, how exactly is personalized recommendation influence users’ attitudes,
does it make things better or worse, this will be a complicated question to
answer. Take Today’s Headline, which is a typical APP that using personalized
recommendation system to attract users, as an example. (see Figure 2)
Figure 2. Today’s Headline’s personal recommendation
Basically, this
personalized recommendation system should contain five key elements, which can
be entry point of variables of user’s satisfaction degree:
1.
Producers, as in people who produce the original content,
could be either user (UGC) or professionals (PGC), if production needs to be
paid, then it is referred to the occupationally-generated Content (OGC).
2.
Content, without the production, in this case, content,
there will no users visit to platform. Personalized recommendation require
content as a fundamental basis.
3.
Consumption platform, a platform providing content for
consumers to access, as in website or APPs like Netease cloud music.
4.
Consumer, meaning the users who enter the platform for
content.
5.
Feedback, refers to the interactive behavior of the
contents when consumers in consumption platform. In the recommended such as
Today’s Headline news app, product or collect news and information, and display
it in the client. Every time users click on one of those news and read the
detailed content formed a feedback. Similarly, a click on a tag at the top of
the navigation, add or delete a channel, collect, offline, share or repeat
click an article, these behaviors all can be regarded as feedback.
Today’s Headline will use
technical method according to the information, to set up the regular user
interest model and the recent interest model after a period of time. Then the
model will be used to trial and error, make adjustment again and again
according to the behavior variance, prompting the model rising up and more and
more closer to the real user preferences.
The Machine Will Not Do
Evil
In the same time, practical
experience reflects that information’s diversity will be sharply cutoff once
started the personal recommendation, and the content will be intensive, even
quality of which is more difficult to control, since the machines are not
responsible for content quality, but only responsible for the potential
audience and popularity of content.
Mechanized judgment
inevitably lack of " personality " or "style", since the
content of the different media has different style, which reflected special personality,
previously content is mostly completed by artificial, so all the content is
with a unique style.
However, recommendation algorithm
is not person, it can just automatically according to existing data to recommend, which perhaps is
the reason why most of content algorithms recommended looks similar.
The system cannot determine the current popular events in a short time, tend to be popular had formed after the machine to discover. That is to say, screening machines have several dimensions, and there also exist invisible factors. No doubt that machine will not do evil, it just continuing make optimization around one goal that put forward by designer. But customers’ goals will sometime have deviation, leading machine to enlarge this deviation.

ReplyDeleteThank you for this interesting and informed piece on personalised recommendation technology. I agree with you that quality control and information diversity can be threatened in this huge trend of algorithmic recommendations.
ReplyDeleteWhile traditional media treat objectivity and unbiased reporting as virtues, new media have a strong focus on technology which matches demands and supplies. Personalised recommendations can be great for users because it promotes efficiency in the age of information explosion.
However, in cases such as Facebook, users are fed with news that support their existing beliefs, political orientation, etc. Even before the advent of social media, scholars had already put forward the idea of selective exposure arguing that people tend to look for, read, interpret and favour information that reinforces their existing beliefs.
With personalised recommendations, new media further encourage this kind of confirmation bias and obstruct users from understanding things from multiple perspectives.
