ONTOLOGY BASED E-LEARNING: ARCHITECTURE

ARCHITECTURE

The main objective of our ontology based e-learning architecture is to identify the user requirement, student’s preferences and characteristic to adapt the course for each single student.

The ontology based e-learning architecture system can classified into three layer.

They are
1. Knowledge base
2. Software interface
3. Application layer (user)

This layer includes profile database, ontology library and traditional material.

The profiles of the date base consist of the leaner data that include the user ID, Authority information. The ontology library gathers the various description information in which, the ontology resources have various description methods such as RDF file ect and it has grammar semantic function .The ontology are mainly built for share and reuse of the knowledge

The traditional material include various teaching material which a certain course needs including teaching content in the class and excise behind .The material are gathered based on the student profile in the database and based on the query of the learner.

Representative APR 391%

Let's say you want to borrow $100 for two week. Lender can charge you $15 for borrowing $100 for two weeks. You will need to return $115 to the lender at the end of 2 weeks. The cost of the $100 loan is a $15 finance charge and an annual percentage rate of 391 percent. If you decide to roll over the loan for another two weeks, lender can charge you another $15. If you roll-over the loan three times, the finance charge would climb to $60 to borrow the $100.

Implications of Non-payment: Some lenders in our network may automatically roll over your existing loan for another two weeks if you don't pay back the loan on time. Fees for renewing the loan range from lender to lender. Most of the time these fees equal the fees you paid to get the initial payday loan. We ask lenders in our network to follow legal and ethical collection practices set by industry associations and government agencies. Non-payment of a payday loan might negatively effect your credit history.
