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).

To assist the interpretation of family memberships, overall probability scores for both global and motif matches are provided for top hit families. The global score is computed from the BLAST e-value, the SSEARCH score, and the percentage of sequence identity at overlapped length ratio in SSEARCH alignment. The motif score is computed from the ratio of mismatched amino acids to ProSite patterns, and the hidden Markov motif match score. Family information from ProClass, with hypertext links to all other major family... 

The web is the most popular Internet application. It allows easy links to information and files which may be located on computers anywhere in the world. The WWW allows access to millions of home pages or websites , the initial point of reference with companies, institutes and individuals. Besides their own text and images, these contain hypertext links , highlighted words or phrases that you chck on to take you to another page on the same website or to a completely different site with related subject material. Certain sites specialize in such links, acting like indexes to other websites these are particularly useful. 

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 ... 

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...

Next to e-mail, the World Wide Web is perhaps the most popular application of the Internet. It is a worldwide connected system of databases containing structured, hypertext, multimedia information that can be retrieved from any computer connected to the Internet.

Tha basic architecture of the Web consists of browsers that act as clients requesting information from Web servers. Computer-to-computer communications are described in terms of protocols, and Web interactions are no exception to this rule. In order to implement the prototype Web, Berners-Lee had to define the interactions that were permissible between server and client (normally a browser, but it could in fact be any program). The HyperText Transfer Protocol (HTTP) describes these interactions. The basis of the design of HTTP was that it should make the time taken to retrieve a document from a server as short as possible. The essential interchange is Give me this document and Here it is. ... 

An important aspect of HTML is that it is readable by humans as well as machines. Given an HTML document, a human reader can make reasonable sense of it. A computer can take the same source and display it in a way suited to whatever output device is available. The outcome of this requirement was that HTML is based on plain text. A mechanism for describing the structure of plain text documents already existed in the ISO standard (ISO standard 8879 1986) for SGML. SGML was widely accepted by the Hypertext research community as an appropriate platform for the description of hyperlinked documents.
