E-Learning Services Discovery Algorithm Based on Context Aware
Zhu Zheng-zhou · 2012
Based on e-Learning service discovery system,an e-Learning service discovery algorithm-eLSDACA was proposed.The algorithm awares the learning context of learners,and then comes into students context ontology.E-Learning context element is used in 2 aspects.The first is that it is used as input properties.The second is that it is the modification element for the e-Learning service discovery system.With the help of the amendatory function,the total matching degree of discovered advertised e-Learning services is modified.Simulation experiments indicate that this algorithm's precision and recall of e-Learning service discovery are all over 90%,and they are all better than the traditional algorithms,after times that learner uses the system to discovery e-Learning service are more than 10.
