Semantic Web

The semantic web is an idea for future network, in such networks, information is endowed with definite meaning, the machine can automatically processing and integration of information available online. The semantic web using XML to define custom tags using RDF format and the flexibility to express data, the next step need is an Ontology network language (such as OWL) to describe the term of a web document specific meaning and the relations between them.

concept

The semantic web is judged according to the semantic web.

Say simply, the semantic web is a kind of can understand human language intelligent network, it can not only understand the human language, and still can make the person and the communication between computers become like interpersonal communication as easily.

Add more used to describe properties and types of vocabulary, such as type of sexual, intersect between base, and equivalence, attribute richer types, properties, characteristics (e.g. symmetry), and enum type.

Basic characteristics

(1) the semantic web is different from now WWW, it is the extension and extend existing WWW;

(2) the existing WWW is facing the document and the semantic web is facing the document represent data;

(3) the semantic web will be more conducive to computer "understanding and processing", and has a certain judgment, reasoning ability.

Although the semantic web showed us a bright prospect of WWW and therefore brought the Internet revolution, but the realization of semantic web is still face a huge challenge:

(1) content available on sex, which based on the semantic web Ontology and constructing web is still a few;

(2) ontology development and evolution, including in all areas of development, the core ontology in the process of developing the methods and technical support, ontology is evolution and annotation and version control problem;

(3) content, namely the scalability of the semantic web content later, how to scalable way to manage it, including how to organize, storage and search;

(4) multilanguage support;

(5) ontology language standardization.

The difference between semantic web and the world wide web

The semantic web "is different from the existing world wide web, its data mainly for human use, the new generation will provide can also for computer WWW of process data, this will make a lot of intelligence service possible"; The semantic web research activities aim is "developed a series of computer can understand and deal with the express semantic information technology to support the language and widely effective under the network environment of automatic reasoning".

At present we have used the world wide web, is actually a storing and sharing image, text media, the computer can only see a bunch of words or images on its content, not to recognize. The world wide web, if the information in the computer to process of words, we must first will these information processed into the computer can understand the ability after the original information process, this is quite troublesome issue. And the semantic web establishment will things get much simpler.

The semantic web is the change of the world wide web nature, its main development task is to make the data more convenient for computer processing and searching. The ultimate goal is to let users into god almighty, the amount of resources to the Internet to almost omniscient degree in these resources, the computer can find the information you need one, thus will the world wide web information island in the development of existing, into a giant database.

The semantic web will make mankind from search related web liberated the hard labor. Because the computer can use their net in search of intelligent software, tens of thousands of pages, through "intelligent agents" were the useful information from related. And unlike now world wide web, just to give you enumerate the useless which turns out tens of search results.

For example, in online registration to attend the meeting, the meeting organizers in website lists time, place, and a nearby hotel discounts information. If using a web of words, now you have to check schedule, and carry on the Internet, and then copy and paste phone or online booking tickets and hotel, etc. But if use, is the semantic web, then everything becomes very simple, when installed in your software will automatically on the computer for you to complete the above steps, you have done is just by a few buttons just using the mouse.

Browse through the news, the semantic web will give every piece of news etc.must label, detailed description of which sentence is the author, which sentence is guide language, which sentence is heading. So, if you in the search engines input "Lao she's works," you can easily find Lao she works and not about his article.

In short, the semantic web is a more colorful, more personalized network, you can give the high trust, let it help you to filter out what you don't like the content, enabling the network more like your own network.
