In order to enlarge the user spectrum and application domain of
WWW, we propose atelephone-accessed browsing system to access
WWW in this thesis. The proposedtelephone-accessed browsing
system is called Phone-Web system. The Phone-Web system actsas
an agent for telephone users to access WWW. Using the Phone-Web
system, users canretrieve and hear information stored in WWW
spaces using telephone sets. In the Phone-Websystem, the
retrieved information is filtered and converted into the
acoustic format,i.e., voice format. To reach the goal, the key
issues of developing the Phone-Web systemare (1) the development
of a hyper phone markup language (HPML) and the HPML
languageinterpreter for specifying and presenting the retrieved
information, respectively, (2) apage processor for fetching
requested web pages that are stored in remote WWW servers, (3)a
media converter for converting the retrieved information into
the voice format, and (4)a telephone engine that can receive
telephone users' calls and requests, and transmit theconverted
voice information to users. In this way, both traditional
telephone informationsystem and WWW system can be integrated
into the Phone-Web system. The user spectrum andapplication
domain of WWW can be enlarged.
