In
the 4th lecture, we learnt sentiment analysis and opinion mining. In
my opinion, this is quite an important topic, because it has great value for
both individuals and organizations.
On
the one hand, it could help individuals to understand what their friends
thinking and feeling so that they will deepen the understanding of their friends
and maintain their relationships better. In addition, we could more likely to
make the right decision when we receive the influence of the others’ point of
view. As we know, it is very
difficult to avoid interference
by others’ opinions and evaluation. In the 4th class, Prof Rosanna
shown us how strong the influence of others’ opinion. She let students who
arrived early to mislead the arrived late students to give wrong answer to a question.
Finally, only few students adhere to the correct answer to the end. Actually, we
are so easily to be influenced by others that we really need sentiment analysis
and opinion mining to judge others’ views.

On
the other hand, for the organizations, understand people’s opinion will be
beneficial to them to improve their products, services and develop their
strategies. One specific thing is public opinion analysis. Public opinion is
the public social and political attitude towards social events. It is
integrated performance of believes, attitudes, opinions and emotions which are expressed
by various social phenomena. When social media become the carrier of public
opinion, public opinion has the following characteristics, higher freedom,
lager information scale, faster propagation velocity, more participants and
more real-time interactivity. These features bring some convenience; however,
it also has some negative effects at the same time. Some rumors and incitement will
cause extreme comments, irrational diatribes and personal attacks. Consequently,
the improvement of sentiment analysis and opinion mining ability will probably make
the social public opinion trend be grasped and guided better. I think, this is
one issue and challenge faced by social media.
