A New Consistency Model in Collaborative Editing Systems
نویسندگان
چکیده
Consistency maintenance is a basic issue in computersupported cooperative editing systems. Aimed at providing a clear, appropriate and extended description on this issue, a new three-level consistency model is proposed: (1) Operation Consistency, which promises all operations are executed at the same order; (2) Content (Syntactic or Intention) Consistency, which promises the effects of all operations are the same at all sites; and (3) Semantic Consistency, which promises the user meanings are the same at all sites. Finally, evaluations on existing collaborative editing systems are discussed.

Consistency in Real-time Collaborative Editing Systems Based on Partial Persistent Sequences
In real-time collaborative editing systems, users create a shared document by issuing insert, delete, and undo operations on their local replica anytime and anywhere. Data consistency issues arise due to concurrent editing conflicts. Traditional consistency models put restrictions on editing operations updating different portions of a shared document, which is unnecessary for many editing scena...

The recommender systems are models that are to predict the potential interests of users among a number of items. These systems are widespread and they have many applications in real-world. These systems are generally based on one of two structural types: collaborative filtering and content filtering. There are some systems which are based on both of them. These systems are named hybrid recommen...
