Use of Hypertext

Full text databases are available from many sources, and will be supplemented by internal sources. With the increased amount of information available via the Internet there is the danger of a surfeit of information. This kind of knowledge base is divergent which does not always lend itself to problem solving. However, developments in the use of hypertext and content sensitive mark-up languages can provide links between databases and give a conceptual framework that... 

The use of hypertext in information science is superior to a traditional linear presentation. It relies on a tree structure. However, it has a serious drawback. Looking at a branch, we have no idea what it represents in the whole diagram, whether it is an important branch or a remote tiny one does it lead further to important parts of the book or it is just a dead end, and so on. At the same time, a glimpse at the TREE shows us that the thick trunk is the most important structure. But what do we mean by important At least two criteria may be used it is important for the... 

The work has a relationship to research on ill-structured domains using hypertext tools. Rand Spiro who has developed Cognitive Rexibility Theory presents useful theoretical underpinnings for the use of hypertext to facilitate the acquisition of ill-structured areas.

The WWW allows the faculty a more flexible way to offer the support that has been provided by text or lecture in the past. The material furnished by means of the WWW can be as simple as a course syllabus, but it can also extend to reference material, homework problems, and animations. There are, however, a number of advantages to offering this information electronically. Perhaps the most important benefit is the use of hypertext to allow the student to interact with the information. This allows the student to make decisions about the order and depth of the coverage. The in.structor detemiines a basic information pathway that will expose the student to... 

GORE. The CORE Electronic Chemistry Library is a joint project of Cornell University, OCLC (On-line Computer Library Center), Bell Communications Research (Bellcore), and the American Chemical Society. The CORE database will contain the full text of American Chemical Society Journals from 1980, associated information from Chemical Abstracts Service, and selected reference texts. It will provide machine-readable text that can be searched and displayed, graphical representations of equations and figures, and full-page document images. The project will examine the performance obtained by the use of a traditional printed index as compared with a hypertext system (SUPERBOOK) and a document retrieval system (Pixlook) (6,116). 

WWW—World Wide Web ( the Web ) a component of the Internet that uses a hypertext-based language to provide resources. 

The electronic IND also features the use of the roadmap.pdf. This is the recommended entry point for the electronic submission. The roadmap, pdf should contain functional hypertext links to the original submissions main TOC and to each subsequent submission s TOC. You should include the submission serial number found in the prefix of each file for that submission (see Appendix A). You should update and resubmit this file with each amending submission. As a result, the roadmap.pdf always will contain a current comprehensive submission history that will enable a reviewer to easily access the original IND and its subsequent amendments through their main TOCs. 

Protocol and Protocol Revisions (amendments) You should provide each protocol in a separate PDF file in a subfolder labeled Protocols. To help us easily identify the file, use the protocol number as part of the file name. Each protocol should have a TOC. You should hypertext link and bookmark the TOC. For protocol revisions or amendments, you should use the same protocol number that identifies the original protocol. You should submit to tie file a complete copy of any revised protocol. This will facilitate the use of the text compare function in Adobe Acrobat by our clinical reviewers. 

HTML, which is also a subset of SGML, was developed as a means of transmitting hypertext documents over a network and specifies how a document should be displayed in a Web browser. HTML, however, describes neither the information content of a document nor its manner of organization. XML precisely fills this void by making use of tags and attributes to extend, validate, and unambiguously structure the content of a document. 

Hypertext Transfer Protocol (HTTP) HTTP is the protocol of the World Wide Web, and is used to send and receive Web pages and other content from an HTTP server (Web server). HTTP makes use of linked pages, accessed via hyperlinks, which are words or pictures that, when clicked on, take you to another page. 

World Wide Web (WWW) This is the graphical extension of the Internet that features millions of pages of information accessed though the use of the Hypertext Transfer Protocol (HTTP). 

In the early stages of the project, a database system centering on personal computer conununication was constructed to enable information to be shared and accessed. At the present moment a different approach is possible with groupware making use of the Internet, and machine interface is possible by means of hypertext browsers such as the World Wide Web. As the database is constructed to her and maintain information, questions such as the following are pertinent ... 

HTML Hypertext markup language. The standard, text-based language used to specify the format of World Wide Web docmnents. HTML files are translated and rendered through the use of Web browsers. 

World Wide Web. The World Wide Web (WWW) is the world wide connection of computer servers and a way of using the vast interconnected network to find and view information from around the world (Bullock, 2003 Stout, 1996). Internet uses a language, TCP/IP for talking back and forth. The TCP part determines how to take apart a message into small packets that travel on the Internet and then reassemble them at the other end. The IP part determines how to get to other places on the Internet. The WWW uses an additional language called the HyperText Transfer Protocol (HTTP). The main use of the Web is for information retrieval, whereby multimedia documents are copied for... 

Hypertext Transfer Protocol (HTTP) is the application-level network protocol for transferring Web content between servers and clients. (Hypertext is a special database system of multimedia objects linked to each other.) HTTP uses the services of the TCP transport protocol. It transfers independently the objects (text, graphics, images, etc.), that build up a page. Together with each object, a special header is also passed. The header contains information alx>ut the type of the object, its size, its last modification time, and so on. HTTP also supports the use of proxy and cache servers. HTTP proxies are implemented in firewalls to pass HTTP traffic between the protected network and the Internet Object caches are used to save bandwidth on overloaded lines and to speed up the retrieval process.
