In this paper, the authors present a preliminary study on the problem of finding products similar to a product given as input, based solely on their attributes. They assume that they are given a set of products from a same category of a same on-line store, were each product is described in a catalog by ...
In this paper, the authors have discussed the task, dataset, and results of the Linked Data Mining Challenge 2015. The submissions show that Linked Open Data is a useful source of information for data mining, and that it can help to build good predictive models. On the other hand, the experiment with majority voting shows ...
In this paper, the authors deal with the design of an effective Android framework that will allow a developer to create Android applications easily in a short time with the help of aspect-oriented approach. Their solution enables to deal with separated aspects like security, layout, input validation, data binding and presentation independently. Their presented framework ...
Interactive music retrieval systems using microphone input have become popular, with applications ranging from whistle queries to robust audio search engines capable of retrieving music from a short sample recorded in noisy environment. The availability for mobile devices brought them to millions of users. Underlying methods have promising results in the case that user provides ...
To support blind people in dealing with graphical user interfaces some two-dimensional Braille devices were developed. In order to ensure an efficient workflow not only the preparation of content, but also the handling of the device has to be well usable. In this paper, the redesign of a touch-sensitive pin-matrix device is discussed. At first, ...
Although DBMS (DataBase Management Systems) are of-ten hidden for a user, they are a part of many applications utilized in day-by-day life. In general, users can suppose two main types of DBMS: OLTP (On-Line Transaction Processing) and OLAP (On-Line Analytical Processing). They can also distinguish another classification related to the connection of a client and ...
In this paper, the authors describe a proposal for enhanced visualization of a data mining model generated with Association Rule (AR) techniques by applying Self Organizing Maps (SOMs). A representation of visual perception model of AR based on a method called AVM-DM (Augmented Visualization Models for Data Mining) is established, together with data and patterns, ...
In this paper, the authors are interested in three technologies, semantic web and ontologies to deliver peer assessment as part of Inquiry Based Learning (IBL) environment. Introducing peer assessment can be a way to force students to take the responsibility to make a judgment about the actual contribution of each of their peers and to ...
Supply chain units are connected by both physical and in-formation flows. Electronic services are used to perform a large part of activities in modern supply chains. The traditional supply chain configuration models pay the main attention to optimization of the physical flows. However, it is equally important to ensure that the physical units have appropriate ...
Companies are ever more interested in process-oriented organizational designs due to the competitive advantages they can achieve. Companies must therefore be able to manage their business process models and deal with quality assurance concerns, especially when business process models are mined by reverse engineering (e.g. from information systems) since it has harmful effects on the ...
