This paper presents a method that acquires new concepts and connections associated with user-selected seed concepts, and adds them to the WordNet linguistic knowledge structure. New domain knowledge can be acquired around some seed concepts that a user considers important. The knowledge we seek to acquire relates to one or more of these concepts, and consists of new concepts not defined in Word...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
in this paper, fourteen mt stations along a profile perpendicular to the main geological structure were used in order to identify the geology of sabalan geothermal field including the extension of the surface cap-rock and clay-cap layers. the mt data collected between 1-8192 hz is of useful quality and provides good control on the surface layers in many areas. it means that reliable modeling sh...
laser-tissue interaction is of great interest due to its significant application in biomedical optics in both diagnostic and treatment purposes. major aspects of the laser-tissue interaction which has to be considered in biomedical studies are the thermal properties of the tissue and the thermal changes caused by the interaction of light and tissue. in this review paper the effects of light on ...
Gravitational waves are a prediction of Einstein's general theory of relativity. These waves are created by massive objects, like neutron stars or black holes, oscillating at speeds appreciable to the speed of light. The detectable effect on the Earth of these waves is extremely small, however, creating strains of the order of 10(-21). There are a number of basic physics experiments around the ...
this study considers the level of increase in customer satisfaction by supplying the variant customer requirements with respect to organizational restrictions. in this regard, anp, qfd and bgp techniques are used in a fuzzy set and a model is proposed in order to help the organization optimize the multi-objective decision-making process. the prioritization of technical attributes is the result ...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
Iran has a great wealth of various naturally occurring medicinal plants which have great potentialpharmacological activities. Ziziphus vulgaris known as Jujube is one of these plants. For a longtime Z. vulgaris has been used in alternative medicine as anti-hyperglycemic, anti-hyperlipidemiaand anti- hypertension. Z. vulgaris has recently been shown to have antibacterial, antioxidant,anti-hyperg...
Concept naming over the taxonomic structure is a useful indicator of the quality of design as well as source of information exploitable for various tasks such as ontology refactoring and mapping. We analysed collections of OWL ontologies with the aim of determining the frequency of several combined name&graph patterns potentially indicating underlying semantic structures. Such structures range ...
We present a simple framework for theta-subsumption testing in Prolog. In its simplest instantiation, it yields an algorithm that takes only a few dozen lines of code. Despite its simplicity, the framework has turned out to work very well on data where a state-of-the-art subsumption engine suffered from excessive run times. The framework can easily be instantiated in different ways, precisely b...
