In-Depth Information
In the second procedure of the developed method, the users' comments
are also considered as clues for finding representative keywords. The users'
comments reflect direct feelings and thoughts of visitors. Using the com-
ments and string of landmarks nearby will help us to find meaningful
objects for visitors.
Although there are some keywords generated by the landmarks selection
engine; sometimes, these keywords cannot cover all objects that users are
interested. The function provided by the wizard is aimed at helping users to
save time from searching reference data on the Internet. Users can still find
resources they want in the travel topic editing phase if they are not satisied
with these web pages searched by the agent.
The information collected by the wizard also provides another type of
record for users. The wizard can obtain geographic data from the GPS and
transfer these data to the landmark selection engine and agent. When visitors
are on their journeys, the information provided by the GPS will be uploaded
in real time. The precise position of visitors changes frequently on a journey. A
route of the journey is obtained by connecting every landmark the user passed.
This information is also very useful for the users to edit their travel blogs.
13.3.2 The intelligent Travel Topic agent
The agent is designed to help visitors to collect related information from the
Internet. It is a program stored in the management server. After the wizard
transmitted keywords generated by the selection engine, these keywords
will be transferred to servers. These keywords are the most important infor-
mation for the agent to search resources.
The searching procedures are similar to ordinary searches on the Internet.
Taking Google as an example, users just need to feed keywords and set
some additional properties and then the searched results will be listed on
a Web page. Integrating such a function to the agent is not a hard task; we
can use hyperlinks compliant with the HTTP protocol to replace the search-
ing behavior by a simple procedure in the agent. For example, if users want
to search information on the Tamkang University, they can key in the key-
words in the search area. Searching information of Tamkang University can
be represented by a hyperlink such as “http://www.google.com/search?hl=
en&q=TamKang+University.” The wizard just needs to follow the form and
change keywords, a search request will be made to the search engine. The
search results are also compliant with the HTTP protocol. The wizard just
needs to parse the result web pages and discover the HTTP address of these
web pages to get reference links.
There are many hyperlinks in the searching result window. By filtering
those unrelated resources, keywords are used to ignore Web pages with names
that are there as advertisements or services provided by search engines. By
parsing and filtering pages returned by search engines, hyperlinks and com-
ments will be gathered and transferred to the management server.
