Operational transformation (OT) is an established optimistic consistency control method in collaborative applications. This approach requires correct transformation functions. In general all OT algorithms only consider two character-based primitive operations and hardly two or three of them support string based two primitive operations, insert and delete. In this paper we have proposed a new al...

recommender systems (rs) provide personalized recommendation according to user need by analyzing behavior of users and gathering their information. one of the algorithms used in recommender systems is user-based collaborative filtering (cf) method. the idea is that if users have similar preferences in the past, they will probably have similar preferences in the future. the important part of col...

Web-based collaboration calls for professional skills and competences to the benefit of the quality of the collaboration and its output. Within this framework, educational virtual environments may provide a means for training upon these skills and in particular the collaborative ones. On the basis of the existing technological means such training may be enhanced even more. Designing considerati...

Background and Objectives: Learning to balance the clinical, educational, scholarly elements of an academic career is challenging for faculty. To increase research output amongst family medicine faculty with limited no publications, we developed Collaborative Scholarship Intensive (CSI) provide participants intensive instruction in methodology coupled structured writing support protected time w...

I this paper, we analyze the contracting issues that arise in collaborative services, such as consulting, financial planning, and information technology outsourcing. In particular, we investigate how the choice of contract type—among fixed-fee, time-and-materials, and performance-based contracts—is driven by the service environment characteristics. We find that fixed-fee contracts contingent on...

Throughout the years software engineers have come up with a myriad of specialized tools and techniques that focus on a certain type of software analysis such as source code analysis, duplication analysis, co-change analysis, bug prediction, or detection of bug fixing patterns. However, easy and straight forward synergies between these analyses and tools rarely exist because of their stand-alone...
