Ontology definition metamodel has been widely adopted in aspect of building ontology. However existing ontology metamodel is only suitable for building ontology in a certain domain. With collaboration and sharing among multiple domains, we face the seriously problem that is how to overcome semantic interoperability. For this problem, we need to combine general ontology with domain ontology and merge all existing ontologies by ontology metamodel. In this paper, we define main components of ontology metamodel and present conditional context and contextual concept unit. In addition, we introduce the method of mapping between conditional context and contextual concept unit. Finally, we use an example about information retrieval to illustrate its function and analysis its feasibility.

Land degradation is a multifaceted phenomenon. In many mountainous and hilly areas that are marginal in terms of their economic and social sustainability, degradation is closely linked to population decline through ageing and outmigration, and to the abandonment of land, leading to a loss of community resilience. These processes acting together can produce positive feedback loops, with the consequential loss of socio-economic resilience at larger spatial scales that can ultimately lead to the disintegration of entire territories. Drawing on recent advances in defining, integrating, and operationalizing the measurement of resilience, this paper took a new approach by exploring changing resilience over an extended period in a rural region of southern Italy. The paper used both quantitative and qualitative methods to test the complex and shifting relationships between multiple domains, as an expression of spatial and temporal patterns of resilience, and examined the impact of shifting resilience on continuing degradation processes. The results suggest that the capacity of socio-ecological systems to respond sustainably to land degradation over an extended period of time is highly dependent on two critical processes: the availability and mobilization of critical factors within the five key domains noted above, and the strength of the temporal and spatial cross-scale relationships between those factors.

98 Minnesota Law Review 868 (2014)Academic and regulatory debates about Google are dominated by two opposing theories of what search engines are and how law should treat them. Some describe search engines as passive, neutral conduits for websites’ speech; others describe them as active, opinionated editors: speakers in their own right. The conduit and editor theories give dramatically different policy prescriptions in areas ranging from antitrust to copyright. But they both systematically discount search users’ agency, regarding users merely as passive audiences.A better theory is that search engines are not primarily conduits or editors, but advisors. They help users achieve their diverse and individualized information goals by sorting through the unimaginable scale and chaos of the Internet. Search users are active listeners, affirmatively seeking out the speech they wish to receive. Search engine law can help them by ensuring two things: access to high-quality search engines, and loyalty from those search engines.The advisor theory yields fresh insights into long-running disputes about Google. It suggests, for example, a new approach to deciding when Google should be liable for giving a website the “wrong” ranking. Users’ goals are too subjective for there to be an absolute standard of correct and incorrect rankings; different search engines necessarily assess relevance differently. But users are also entitled to complain when a search engine deliberately misleads them about its own relevance assessments. The result is a sensible, workable compromise between the conduit and editor theories.

With the great mass of the pages managed through the world, and especially with the advent of the Web, it has become more difficult to find the relevant pages after an interrogation. Furthermore, the manual filtering of the indexed Web pages is a laborious task. A new filtering method of the annotated Web pages (by our semantic annotation process) and the non-annotated Web pages (retrieved from search engine “Google”) is then necessary to group the relevant Web pages for the user. In this paper, the authors will first synthesize their previous work of the semantic annotation of Web pages. Then, they will define a new filtering method based on three activities. The authors will also present their querying and filtering component of Web pages; their purpose is to demonstrate the feasibility of the filtering method. Finally, the authors will present an evaluation of this component, which has proved its performance for multiple domains.

Abstract An integrated design for manufacture system that performs manufacturability analysis simultaneously in two domains using interchangeable process specific entities is presented. This new approach is illustrated by an integrated system that creates and evaluates parts for manufacture by injection molding using a C-entity, and simultaneously creates and evaluates its mold for manufacture by milling using the fundamental manufacturing entity for milling. The entity for the part manufacturing process is chosen as the complement of the entity for the mold manufacturing process. This obviates the need for converting features from one manufacturing domain to another, and also permits a single uniform data structure to capture the shape characteristics of parts made in the two manufacturing domains. Since all the shapes are represented in the same way, the manufacturability evaluation of the part and the mold is reduced to a small set of algorithms based on an evaluation of the entity’s profile. It is demonstrated that by using process specific entities one can perform manufacturability evaluation of a part without either feature extraction or designing with features. The advantages of using the process specific entities approach for design and manufacturability evaluation over the feature recognition and the design by features approach are enumerated.

As web contents grow, the importance of search engines become more critical and at the same time user satisfaction decreases. Query recommendation is a new approach to improve search results in web. In this paper a method is proposed that, given a query submitted to a search engine, suggests a list of queries that are related to the user input query. The related queries are based on previously issued queries, and can be issued by the user to the search engine to tune or redirect the search process. The proposed method is based on clustering processes in which groups of semantically similar queries are detected. The clustering process uses the content of historical preferences of users registered in the query log of the search engine. This facility provides queries that are related to the ones submitted by users in order to direct them toward their required information. This method not only discovers the related queries but also ranks them according to a similarity measure. The method has been evaluated using real data sets from the search engine query log.

Both human face recognition and generation by machines are currently an active area of computer vision, drawing curiosity of researchers, capable of performing amazing image analysis, and producing applications in multiple domains. In this paper, we propose a new approach for face attributes classification (FAC) taking advantage from both binary classification and data augmentation. With binary classification we can reach high prediction scores, while augmented data prevent overfitting and overcome the lack of data for sketched photos. Our approach, named Augmented binary multilabel CNN (ABM-CNN), consists of three steps: i) splitting data; ii) transformed-it to sketch (simplification process); iii) train separately each attribute with two convolutional neural networks; the whole process includes two networks: the first (resp. the second) one is to predict attributes on real images (resp. sketches) as inputs. Through experimentation, we figure out that some attributes give high prediction rates with sketches rather than with real images. On the other hand, we build a new face dataset, more consistent and complete, by generating images using Style-GAN model, to which we apply our method for extracting face attributes. As results, our proposal demonstrates more performances compared to those of related works.

Given the newest trends in business and the growing interest towards Internet of Things, it became natural that economic environment switched the paradigm of classical business model. Blockchain technology is a very timely topic of discussion both in academic environment and outside it. This element was proven by authors when analyzing the topic towards the number of publication releases and the search engine queries. Furthermore, the authors shaped the framework of blockchains‘ development highlighting the main advantages and disadvantages for Industry 4.0.
