“…Developers engage in retention actions very frequently and the reuse of code related resources has a strong correlation to relevance [30,19,31,34,35,36]. Software developers understand that the use of retention actions accelerates their work, allows them to distribute their cognitive resources and improves the maintainability of code [35].…”

The importance of information retrieval systems is unquestionable in the modern society and both individuals as well as enterprises recognise the benefits of being able to find information effectively. Current code focused information retrieval systems such as Google Code Search, Codeplex or Koders produce results based on specific keywords and therefore they do not take into account developers' context such as development language, technology/framework, goal of the project, project complexity and maturity or developer's domain expertise. They also impose additional cognitive burden on users in switching between different interfaces and clicking through to find the relevant code. Hence, they are not used by software developers. In this paper, we discuss how software engineers interact with information and general purpose information retrieval systems (e.g. Google, Yahoo) and investigate to what extent domain-specific search and recommendation utilities can be developed in order to support their work related activities. Based on our user studies, we found that software engineers followed many identifiable and repeatable work tasks and behaviours. These behaviours can be used to develop implicit relevance feedback based systems. Based on our results, we discuss the implications for the development of task-specific search and collaborative recommendation utilities embedded with the Google standard search engine and Microsoft IntelliSense for retrieval and reengineering of code. We have implemented a prototype of the proposed collaborative recommendation system which was evaluated in a controlled environment simulating the real world situation of professional software engineers. The evaluation has achieved promising initial results on the precision and recall performance of the system.

“…There has been substantial research on means to mitigate content pollution in CDS, leading to the proposal of several generic countermeasure mechanisms (CAI et al, 2009;ANAND;BHASKAR, 2011;SHIN;REEVES, 2012). Although these are interesting strategies to fight pollution, they try to identify and isolate suspicious content after publication.…”

Abstract-As P2P multimedia streaming service is becoming more popular, it is important for P2P-VoD content providers to protect their servers identity. In this paper, we first show that it is possible to launch an "identity attack": exposing and identifying servers of peer-to-peer video-on-demand (P2P-VoD) systems. The conventional wisdom of the P2P-VoD providers is that identity attack is very difficult because peers cannot distinguish between regular peers and servers in the P2P streaming process. We are the first to show that it is otherwise, and present an efficient and systematic methodology to perform P2P-VoD servers detection. Furthermore, we present an analytical framework to quantify the probability that an endhost is indeed a P2P-VoD server. In the second part of this paper, we present a novel architecture that can hide the identity and provide anonymity protection for servers in P2P-VoD systems. To quantify the protective capability of this architecture, we use the "fundamental matrix theory" to show the high complexity of discovering all protective nodes so as to disrupt the P2P-VoD service. We not only validate the model via extensive simulation, but also implement this protective architecture on PlanetLab and carry out measurements to reveal its robustness against identity attack.
