A goal for the creation and improvement of music recommendation is to retrieve users’ preferences and select the music adapting to the preferences. Although the existing researches achieved a certain degree of success and inspired future researches to get more progress, problem of the cold start recommendation and the limitation to the similar music have been pointed out. Hence we incorporate c...

Current search engines with arrays of servers can provide efficient web content services. However, as their returned results are usually enormous mass, finding target information is still time-consuming. To increase the correctness of returned results, different page ranking methods were introduced. Some of them also try to use users’ feedback to increase their precision in ranking. However, as...

Traditional database systems can deal with perfect data. But lot of information is present in imperfect form due to vagueness or imprecision. [16] Fuzzy set theory has been applied to deal with imperfections of data and to enhance the accessibility of databases. When users work with usual software tools they have to change their many valued logical thinking (approximate reasoning) into the twov...

This article presents a concept of distance sound source sonification for virtual auditory displays in the context of the creation of an assistive device for the visually impaired. In order to respond to user needs, three sonification metaphors of distance based on sound effects were designed. These metaphors can be applied to any type of sound and thereby satisfy all aesthetic desires of users...

Abstract— In this paper, we investigate a joint source-network coding scheme for adapting a scalable video bitstream. Both embedded bitstream and error-control codes are easily and precisely adapted in a multidimensional way at intermediate overlay nodes to satisfy multiple heterogeneous users without complex transcoding. These distributed nodes form an overlay service network, and adapt both t...

ion and Stepwise Refinement The specifications described above must embody the key concept of Abstraction if they are to be successful. To be abstract, a specification must include the essential requirements that an object must satisfy and omit the unessential. A service specification is abstract primarily in the sense that it a specification must include the essential requirements that an obje...

In this paper, a new approach for optimizing disparity candidates space is proposed for the solution of dense stereo matching problem. The main objectives of this approachare the reduction of average number of disparity candidates per pixel with low computational cost and high assurance of retaining the correct answer. These can be realized due to the effective use of multiple radial windows, i...

With the recent surge of social networks like Facebook, new forms of recommendations have become possible – personalized recommendations of ads, content, and even new social and product connections based on one’s social interactions. In this paper, we study whether “social recommendations”, or recommendations that utilize a user’s social network, can be made without disclosing sensitive links b...

This article investigates the role of transportation in concept tests (i.e., a vivid mental image of a new product concept and the way of using it) for radically new products. Based on transportation literature, the article proposes that concept descriptions in a story format can stimulate transportation. Further, the article builds on the literature on domain-specific skills to propose that te...

Functional Dependency (FD) has been extensively studied in database theory. Most recently there have been some works investigating the implications of extending Description Logics with functional dependencies. In particular the OWL ontology language offers the functional property property allowing simple functional dependency to be specified. As it turns out, more complex FD specified as concep...
