According to a report online [34], more than 200 million unique users search for jobs online every month. This incredibly large and fast growing demand has enticed software giants such as Google and Facebook to enter this space, which was previously dominated by companies such as LinkedIn, Indeed, Dice and CareerBuilder. Recently, Google released their “AIpowered Jobs Search Engine”, “Google For Jobs”...
MOOC develops quite well and provides a new learning platform, which becomes a prominent representative of big data due to its massive behavior data accumulated in the process of using vast teaching resources. Big data analytics technology based on MOOC is a new research trend and its frame can be involved in four stages: where to get big data (Where), what are data types of MOOC (What), how to deal...
Problem of belief revision and specification evolution has been studied for years. Researchers have proposed ACM theory and R-calculus to solve the problem. This paper concerns with the revision of proposition logic and proposes a revision algorithm which can automatically find out a revision of given sets. The correctness of the algorithm is proved and concepts such as basic proposition, assignment...
The personalized learning resource recommendation, as one higher level of the requirements for the learning based on resources of people in the Internet age, has been paid more attention by researchers. Some existing researches can provide personalized learning resources services for learners, but few of them considers the learner's needs for learning resources from a cognitive style point of view...
To create reliable, safe, and high quality software is the primary purpose of software testing. With the development of software engineering, functional software testing is one essential part of software testing. This paper explains that back-propagation neural networks can be used for functional software testing efficiently and significantly. In here we established a method which is sufficient to...
We design a broad-angle polarization beam splitter consisting of alternating layers of dielectric and ultra-low permittivity material. Within wide range of incident angles, it shows high transmissivity for one polarization while high reflectivity for another.
This paper puts forward an algorithm about spatial association rule mining which is based on concept lattice. Firstly, spatial data and their relationships are abstracted into a generic relationship database. Then we can build the spatial concept lattice by the method of mining association rules in the relationship database. At last an improvement algorithm of spatial association rule mining based...
