An analysis of the hypertext in information technology

These majors require a series of lower-division courses, and prerequisites constrain the order in which they can be taken. Junior-level transfer students who must complete a significant part of this sequence may find that it will take longer than two years at UCI to complete their degree. For Fall applicants, a minimum grade of B will be expected for each major's required courses for admission.

An analysis of the hypertext in information technology

General considerations Basic concepts Interest in how information is communicated and how its carriers convey meaning has occupied, since the time of pre-Socratic philosophers, the field of inquiry called semioticsthe study of signs and sign phenomena. Signs are the irreducible elements of communication and the carriers of meaning.

The American philosopher, mathematician, and physicist Charles S. Peirce is credited with having pointed out the three dimensions of signs, which are concerned with, respectively, the body or medium of the sign, the object that the sign designates, and the interpretant or interpretation of the sign.

Peirce recognized that the fundamental relations of information are essentially triadic; in contrast, all relations of the physical sciences are reducible to dyadic binary relations. Another American philosopher, Charles W. Morrisdesignated these three sign dimensions syntactic, semantic, and pragmaticthe names by which they are known today.

Information processes are executed by information processors. For a given information processor, whether physical or biological, a token is an object, devoid of meaning, that the processor recognizes as being totally different from other tokens. Objects that carry meaning are represented by patterns of tokens called symbols.

The latter combine to form symbolic expressions that constitute inputs to or outputs from information processes and are stored in the processor memory.

Information processors are components of an information system, which is a class of constructs. An abstract model of an information system features four basic elements: The processor has several functions: The memory stores symbolic expressions, including those that represent composite information processes, called programs.

The two other components, the receptor and the effectorare input and output mechanisms whose functions are, respectively, to receive symbolic expressions or stimuli from the external environment for manipulation by the processor and to emit the processed structures back to the environment.

The power of this abstract model of an information-processing system is provided by the ability of its component processors to carry out a small number of elementary information processes: The model, which is representative of a broad variety of such systems, has been found useful to explicate man-made information systems implemented on sequential information processors.

Because it has been recognized that in nature information processes are not strictly sequential, increasing attention has been focused since on the study of the human brain as an information processor of the parallel type.

The cognitive sciencesthe interdisciplinary field that focuses on the study of the human mind, have contributed to the development of neurocomputers, a new class of parallel, distributed-information processors that mimic the functioning of the human brainincluding its capabilities for self-organization and learning.

So-called neural networkswhich are mathematical models inspired by the neural circuit network of the human brain, are increasingly finding applications in areas such as pattern recognition, control of industrial processes, and finance, as well as in many research disciplines.

Information as a resource and commodity In the late 20th century, information acquired two major utilitarian connotations. On the one hand, it is considered an economic resource, somewhat on par with other resources such as labour, material, and capital.

This view stems from evidence that the possession, manipulation, and use of information can increase the cost-effectiveness of many physical and cognitive processes. The rise in information-processing activities in industrial manufacturing as well as in human problem solving has been remarkable.

Analysis of one of the three traditional divisions of the economy, the service sectorshows a sharp increase in information-intensive activities since the beginning of the 20th century.

By these activities accounted for half of the labour force of the United States. As an individual and societal resource, information has some interesting characteristics that separate it from the traditional notions of economic resources.

Unlike other resources, information is expansive, with limits apparently imposed only by time and human cognitive capabilities. Its expansiveness is attributable to the following:There is even a progressive analysis of the possible forms of giving applications like Web browsers a more powerful hypertext functionality.

What this meant was that an entire technology of "hypertext for the Web" had sprung up. Hypertext apparently induces at least some of the users to describe the main topics of their document as a kind of "information landscape" or "information map" where the distance between two concepts and their relative position on the screen conveys more information about the underlying concepts than any hierarchical structure.
