Information apparatus having automatic web reading function
First Claim
1. An information apparatus with an automatic browsing function, said information apparatus comprising:
- access means for accessing documents on the Internet;
storage means for storing data of the accessed documents; and
automatic Web tracing means for sequentially and automatically tracing link destinations according to a predetermined rule and parameters based on link information which is defined in the documents stored in the storage means;
wherein said predetermined rule is one of a depth-first search and a width-first search and said parameters include at least a link depth limit to be used when the link destinations are sequentially traced downward and a time interval at which control moves from one document to another; and
wherein said automatic Web tracing means include a history table in which a page access information history is stored each time control moves from a link source to ones of the link destinations and a read-page table in which information indicating, for each link destination of each link in a page, whether the link destination was visited or not, wherein said history table is referenced when control returns from one of the link destinations to the link source during automatic Web tracing and said read-page table is referenced to check for unread links.

Abstract
An information apparatus which has access means by which a document on the Internet is accessed and automatic Web tracing means which automatically trace link destinations successively according to a predetermined rule and parameters based on the link information which is set in the accessed document. The predetermined rule is either a depth-first search or a width-first search. The predetermined parameters include at least a link depth limit to be used when the link destinations are traced downward in the hierarchy, an interval of time required for a transit from one document to another, and an automatic Web tracing time-out time. The rule and parameters may be specified by a user. Automatic Web tracing may be performed either on-line or off-line. Thus, time-varying information can passively be received as if it were television information, minimizing operation steps necessary for a user to perform the automatic Web browsing of the Internet.

7. A computer-readable recording medium having stored therein a computer program which comprises the functions of:
-
accessing documents on the Internet; and
sequentially and automatically tracing link destinations automatically according to a predetermined rule and parameters based on link information defined in the accessed documents;
wherein said predetermined rule is one of a depth-first search and a width-first search and said parameters include at least a link depth limit to be used when the link destinations are sequentially traced downward and a time interval at which control moves from one document to another; and
wherein said function of sequentially and automatically tracing link destinations uses a history table in which a page access information history is stored each time control moves from a link source to ones of the link destinations and a read-page table in which information indicating, for each link destination of each link in a page, whether the link destination was visited or not, wherein said history table is referenced when control returns from one of the link destinations to the link source during automatic Web tracing and said read-page table is referenced to check for unread links. - View Dependent Claims (8, 9, 10, 11, 12)
