The ROLE project (Responsive Open Learning Environments, EU 7th framework program, grant agreement no.: 231396, 2009 – 2013) was focused on the next generation of Personal Learning Environments (PLEs). A ROLE PLE is a bundle of interoperating widgets – often realized as cloud services – used for teaching and learning. In this paper, the authors ...
A computer representation of teaching-learning processes in collaborative learning settings consists of modeling not only the sequence of learning activities and educational resources as existing learning design languages propose, but also modeling both the sequence of invocations of tools needed to carry out the learning activities and the flow of data among those tools. Existing ...
An approach to predict from a data stream of real estate sales transactions based on ensembles of genetic fuzzy systems was presented. The proposed method relies on incremental expanding an ensemble by models built over successive chunks of a data stream. The output of aged component models produced for current data is updated according to ...
In the past, many algorithms have been proposed for mining association rules from binary databases. Transactions with the quantitative values are, however, also commonly seen in real-world applications. Each transaction in a quantitative database consists of items with their purchased quantities. The Multiple Fuzzy Frequent Pattern tree (MFFP-tree) algorithm was thus designed to handle a ...
The linked open data project provides a new publishing paradigm for creating machine readable and structured data on the Web. Currently, the significant presence of data sets describing scholarly publications in the linked data cloud underpins the importance of linked data for the scientific community and for the open access movement. However, these semantically rich ...
