User feedback regarding a displayed item, such as a web page, is obtained by providing a first and second transport-control elements, such as back buttons, that have the same effect for moving within or between displayable items but which have different associated semantic information. Upon activation of one of the transport-control elements, not only is the required movement effected, but data is output or stored indicative of the semantic information associated with the activated transport-control element.

A method and several variants for using information about the scope of access of objects acted upon by mutual exclusion, or mutex, locks to transform a computer program by eliminating locking operations from the program or simplifying the locking operations, while strictly performing the semantics of the original program. In particular, if it can be determined by a compiler that the object locked can only be accessed by a single thread it is not necessary to perform the "acquire" or "release" part of the locking operation, and only its side effects must be performed. Likewise, if it can be determined that the side effects of a locking operation acting on a variable which is locked in multiple threads are not needed, then only the locking operation, and not the side effects, needs to be performed. This simplifies the locking operation, and leads to faster programs which use fewer computer processor resources to execute; and programs which perform fewer shared memory accesses, which in turn not only causes the optimized program, but also other programs executing on the same computing machine to execute faster. The method also describes how information about the semantics of the locking operation side effects and the information about the scope of access can also be used to eliminate performing the side effect parts of the locking operation, thereby completely eliminating the locking operation. The method also describes how to analyze the program to compute the necessary information about the scope of access. Variants of the method show how one or several of the features of the method may be performed.

A method and apparatus for identifying coherent areas within a Web page. First, a Web page is parsed into an HTML DOM tree and an HTML tag token stream. Next, repeated-patterns are induced from the Web page. After filtering out improper repeated-patterns and generating corresponding instances of the repeated-patterns, the repeated-patterns are mapped back to corresponding regions in the Web page. Based on the mappings, a hierarchical RST tree containing information blocks is generated. Information items within the information blocks are detected then used to generate a hierarchical structural information block tree. Information blocks from the structural information block tree are then classified into text information blocks and link information blocks. Based on the classification and block semantic similarity, the bocks are clustered then grouped into semantic information blocks. The semantic information blocks contain main text information blocks and related link blocks which, if necessary, can be labeled.
