The concept of semantic web
Semantic web - a superset of the existing World Wide Web, which aims to make information that is available online, more understandable to computers. It is known that almost all information on the Internet is in text form. It is no secret also that progress in the field of human language processing is very slow. Computers can not accept and comprehend verbal information posted online, and soon probably will not. Then the question arises - how to make computers understand the content posted on the information and take advantage of computers to teach her? This question and answer concept called the semantic web. The word "semantic" in this case means "meaningful", "clear».
In terms of machine data - semantic web "- this idea of storing data in a way that they are defined and related opportunities for further automated processing.
"Semantic Web" will introduce the structure in the semantic content of Web pages, thus creating an environment where software agents, moving from page to page will be able without difficulty to perform complex user queries.
RedTram "Semantic Web" may issue only sites that mention the accuracy of searches in the concept, rather than random pages of text which faced this multivalued keyword. Today's search engines often give out countless pages that does not relate to the request, lifted a long user manual selection of material.
"Semantic Web"; named every concept simply by URI-ID will allow everyone to express new concepts that he invented, with minimal effort.
In terms of service of human needs - the idea of semantic "Web" is the liberation of man from the cumbersome routine tasks of production, searching, recording and indexing information contained on the Web. semantic "web" - a next generation Internet, which allows web-applications to automatically collect web-documents from different sources into account and process information and interact with other applications to perform complex tasks.
"Semantic Web", based on the mathematical notion of graph, which nodes - the notion of subject area, and the arc - the links between them, the most convenient for modeling user queries, and specific information requests to the existing SQL. The problem of finding a solution to the knowledge base type "semantic Web" is reduced to the search network fragment corresponding to a certain subnet, reflecting the request put to the database.
When automatic information processing in the "semantic Web" services that interact with one another on the basis of semantic relationships between objects and concepts that are stored on the Internet should select only that information which will really benefit users.
Articulate semantic basis of subject area, allows for more "meaningful" analysis of information in electronic documents. What it is expressed, first, any natural-language structures through which can be expressed and or other information, contains explicit or implicitly by a subject of discussion, the semantic identity that can be realized due to the domain ontology, in addition, can be identified potential relationships between objects and identified in the text. Second, information in electronic documents, especially one that posted on the Internet often or structured, or contains structured islands of information in lists, tables. Identification of the information in the form of names of attributes that make headlines structured information can also be done via the ontology. Without ontology, the island of structured information can be properly programmed processor divided by the value and description of these values, that are properly constructed chain attribute-value list or describe the table. Therefore it seems appropriate to use a domain ontology for identification of semantic objects and their relationships in presenting information in electronic documents.
Semantic Web technologies outline a general framework that allows data sharing and reuse in different applications, corporations and even communities. Semantic Technology Web - an effective way to present data on the Internet. This structure can also be symbolically identified with the database associated with the global content of the documents online. And this relationship is way clear to your computer. Semantic technologies represent information using ontologies and provide reasoning, using links, rules, logic and conditions stipulated in the ontology.
