These rankings are often taken as indicators of reputation and used for a variety of purposes, such as evaluating the performance of academic institutions and individual scientists, or selecting target conferences for paper submissions. Current rankings are based on a combination of objective criteria and subjective opinions that are collated and reviewed through largely manual processes. In this setting, the aim of this paper is to shed light into the following question: to what extent existing conference rankings reflect objective criteria, specifically submission and acceptance statistics and bibliometric indicators? The paper specifically considers two conference rankings in the field of Computer Science: an Australian national ranking and an informal communitybuilt ranking. It is found that, while in the former ranking acceptance rate is the dominant criterion, in the latter one, both acceptance rate and bibliometric indicators are equally important determinants of rank. It is also found that in both rankings, top-tier conferences can be identified with relatively high accuracy through acceptance rates and bibliometric indicators. On the other hand, acceptance rates and bibliometric indicators fail to discriminate between

With Gelee we aim at filling two lacks we identify in current cooperative software systems when it comes to unstructured, artifact-based works (e.g., the writing of a project deliverable): the lack of state and the complete lack of automated actions. Lifecycles allow us to model the state of any object, and if we focus on online resources (e.g., a Google Doc) then we can also automate some lifecycle actions. If we apply Gelee to composite artifacts, e.g., a set of web services, lifecycles provide for the human-driven orchestration of services.

This excellence, however, has no standard definition and varies across disciplines, and even from person to person, making it difficult to evaluate research and reputation of researchers. In this work, we introduce the general problem of studying the nature of reputation in the context of computer science, providing preliminary results on its relation with bibliometric indicators and hints for future experiments that will foster a better understanding of reputation in the scientific domain.
