A Model Of Semantic Web In Special Domain

Recent years, semantic network technology has became present Internet focus of technical research . It's goal is developing a series of new technology , changing existed Internet rely on characters information come mode of shared resource , through semantic sharing of information, and semantic operation , realize network intellectuality of information service , automatically coming on. The ontology layer is the most important part in network technology of semantic. The concept of the "ontology" originated from the philosophy field at first, " described the system of the objective reality thing in the world, namely existing "; On the artificial intelligence circle, they defined the ontology as " provide the basic term and relation in the relevant domain vocabulary and utilize term and regulation these vocabulary definition of rule of epitaxy that relation form these "; The ontology is applied to Internet's research field nowadays, defined " the ontology is that the definite norm of dealing in generality proves ". A ontology has been described one model formalized and shared in a specific research field . Ontology is usually described a different , scattered , and half information resources of structurization in internet. Through defining shared and versatile special field theory, the ontology helps people to clearly exchange from machine, support semantic operation , but only phraseological operation.The ontology layer is composed of three basis metas: class or conception, relation, instance. I has made deeply studying to form the expression and construction of the ontology, then adopted using XML language to describing the ontology . The grammar and norm of XML have been already very ripe, from the point of view of data, it is a suit specific structure of need is it show independent overall way of message any to come to use. And XML is able to establish, operate and show according to specific land issue datum of mark. Tell as above , with XML to describe ontology , it can express the concept of the ontology as the element of XML, the attribute of the concept shows for the sub element. Relation at the same time can look on as the concept, it has own attribute too. Reasoning process is all carried out on the ontology layer, so according to the ontology layer defined, should analyze XML file first , saves relation information in a vectorial form , then search for. Depth is the superior is similar to tree all over calendar , ahead of root all over popularization of calendar tree ahead of root to search for to have priority. What the width had priority to search for and is similar to with the tree, according to the course all over the calendar of level. Inspire the search algorithm of information to optimize the course of searching for through defining the function of inspiring or utilizing attribute of the relation. At present, because of still without unity semantic network ontology layer and reasoning definition of method in the world, so this thesis use ontology layer and method of reasoning to have a general meaning very much, may be a bit unsuitable in other some fields, can be said to be a kind of exploration of the semantic network and study.The purpose of this thesis is to realize that one semantic network systems of facing the specific field. We regard automatic laboratory of software as the basic range , including all data information among them, mainly defined teacher, students, the thesis, things, other so on, and reciprocity reaction of defined instance. At last it will finish simple reasoning work, and offer the meaningful reasoning result to want finally. Make users send asking on the customer terminal finally , is carrying out to operate correspondingly in serving terminal , then it give returned result to the customer. For consistency of guaranteeing, the user of no authority can't revise the ontology. The semantic network systematic model of this thesis is adopted five layers of structure. The first layer is GUI layer, mainly offer a graphical user interface to user, it is convenient...
