In-Depth Information
Usefulness of the Web page is based on the described content of it. However, the
usefulness of a person on the social web service as an information source is the
expectation for the information which the person will inform in the future.
Intuitive definition of “trust” in this chapter is the expectations for reliability and
usefulness of the information a person will disseminate. Our motivation is to
present a platform to evaluate the trust of the individuals and companies as an
information source over the social Web services.
5.2 The Concept of Trust
There are various definitions for the concept of trust. First, we will try to organize
the concept of trust.
5.2.1 Trust for Governance and Trust for the Market
There are two types of trust based on the purpose of it: trust for the market and trust
for governance. The purpose of the trust for governance is that a certain range of
members are allowed safe interaction with each other under the guarantee of an
authority. The purpose of the trust for the markets is to minimize the risks for
companies that do business in the open market where anyone can participate.
Trust for governance limits the number of members to be included. On the other
hand, the trust of the market does not exclude any person. The trust of these two, in
fact, are neither independent or mutually exclusive. In order to make its foundation
firm, trust for the market uses the trust for governance. However, we should not
confuse these different meanings of “trust”.
5.2.2 Definition of Trust in Social Psychology
Social psychology also has a lot of proposals for the definition of the concept of trust.
Yamagishi defined trust as “expectations for the order of the social morality”
(Yamagishi
1998
). Furthermore, Yamagishi gave a more detail definition that includes:
(1) expectations for the party's ability to accomplish it, and (2) expectations for the
willingness to perform the responsibility of the party. Yamagishi also pointed out that
the (3) meta-communications needed for the trust to state to the party, “I believe you”,
is an important element for establishing trust (Yamagishi and Yoshikai
2009
). In the
area of finance, an example of trust in the ability of a financial person is his/her income,
an example of the trust in their motivation is the mortgage, and an example of the trust
in the meta-communication of a financial person is the financial contract.
We adopt these three definitions of trust for our discussion.
