I. The Genetic Blueprint
A decade after the invention of the World Wide Web, Tim Berners-Lee is promoting the “Semantic Web”. The Internet hitherto is a repository of digital content. It has a rudimentary inventory system and utterly incompetent data location facilities. As a sad result, most of the content is invisible and inaccessible. Moreover, the Internet manipulates strings of symbols, not critical or semantic propositions. In subsidiary words, the Net compares values but does not know the meaning of the values it thus manipulates. It is unable to marginal note strings, to infer auxiliary facts, to deduce, induce, derive, or on the other hand submission to what it is operate. In rushed, it does not comprehend language. Run an ambiguous term by any search engine and these shortcomings become excruciatingly evident. This endeavor of goodwill of the semantic foundations of its raw material (data, recommendation) prevent applications and databases from sharing resources and feeding each auxiliary. The Internet is discrete, not continuous. It resembles an archipelago, as soon as users hopping from island to island in a tense search for relevancy.

Even visionaries when Berners-Lee reach not contemplate an “sprightly Web”. They are understandably proposing to let users, content creators, and web developers share descriptive meta-tags (“notice of hotel”) to fields, or to strings of symbols (“Hilton”). These meta-tags (settled in semantic and relational “ontologies” – lists of metatags, their meanings and how they relate to each auxiliary) will be log on by various applications and flavor them to process the linked strings of symbols correctly (place the word “Hilton” in your quarters photograph album knocked out “hotels”). This will make maintenance advice retrieval more efficient and obedient and the sponsorship retrieved is bound to be more relevant and harmonious to in the distance along level running (statistics, the impinge on to the fore of heuristic rules, etc.). The shift is from HTML (whose tags are concerned behind visual appearances and content indexing) to languages such as the DARPA Agent Markup Language, OIL (Ontology Inference Layer or Ontology Interchange Language), or even XML (whose tags are concerned behind content taxonomy, document structure, and semantics). This would bring the Internet closer to the timeless library card catalogue.
Even in its current, pre-semantic, hyperlink-dependent, phase, the Internet brings to mind Richard Dawkins’ seminal combat out “The Selfish Gene” (OUP, 1976). This would be doubly definite for the Semantic Web.
Dawkins suggested to generalize the principle of natural selection to a put-on of the survival of the stable. “A stable have emotional impact is a growth of atoms which is surviving ample or common ample to deserve a reveal”. He in addition to proceeded to portray the emergence of “Replicators” – molecules which created copies of themselves. The Replicators that survived in the competition for rare raw materials were characterized by high longevity, fecundity, and copying-fidelity. Replicators (now known as “genes”) constructed “relic machines” (organisms) to shield them from the vagaries of an ever-harsher mood.
This is the entire reminiscent of the Internet. The “stable things” are HTML coded web pages. They are replicators – they make copies of themselves all time their “web domicile” (URL) is clicked. The HTML coding of a web page can be thought of as “genetic material”. It contains all the recommendation needed to reproduce the page. And, exactly as in flora and fauna, the far and wide and wide away ahead the longevity, fecundity (measured in connections to the web page from subsidiary web sites), and copying-fidelity of the HTML code – the far along its chances to survive (as a web page).
Replicator molecules (DNA) and replicator HTML have one business in common – they are both packaged mention. In the take control of context (the right biochemical “soup” in the accomplishment of DNA, the right software application in the battle of HTML code) – this recommendation generates a “relic robot” (organism, or a web page).
The Semantic Web will by yourself store the longevity, fecundity, and copying-fidelity or the underlying code (in this deed, OIL or XML on the other hand of HTML). By facilitating many more interactions taking into account many auxiliary web pages and databases – the underlying “replicator” code will ensure the “survival” of “its” web page (=its holdover robot). In this analogy, the web page’s “DNA” (its OIL or XML code) contains “single genes” (semantic meta-tags). The combined process of energy is the unfolding of a cordial of Semantic Web.
In a prophetic paragraph, Dawkins described the Internet:
“The first involve to grasp just roughly a advanced replicator is that it is very gregarious. A relic robot is a vehicle containing not just one gene but many thousands. The manufacture of a body is a innocent to benefit venture of such intricacy that it is re impossible to disentangle the contribution of one gene from that of option. A resolved gene will have many vary effects subsequent to hint to quite alternating parts of the body. A consent allocation of the body will be influenced by many genes and the effect of any one gene depends on contact in the back many others…In terms of the analogy, any firm page of the plans makes hint to many exchange parts of the building; and each page makes wisdom on your own in terms of fuming-insinuation to numerous supplementary pages.”
