Experimental studies have been used as a mechanism to acquire knowledge through a scientific approach based on measurement of phenomena in different areas. However it is hard to run such studies when they require models (simulation), produce amount of information, and explore science in scale. In this case, a computerized infrastructure is necessary and constitutes a complex system to be built. In this paper we discuss an experimentation environment that has being built to support large scale experimentation and scientific knowledge management in software engineering.

Provenance refers to the origin of a particular object. In computational terms, provenance is a historical record of the derivation of data that can help to understand the current record. In this context, this work presents a proposal for software processes improvement using a provenance data model and an ontology. This improvement can be obtained by process data execution analysis with an approach called PROV-Process, which uses a layer for storing process provenance and an ontology based on PROV-O.

In a decision-making process, a systematic method to manage and measure negotiation aspects provides crucial information to negotiators and has emerged as a key factor to determine agreements' success or failure. Accordingly, this work aims at presenting a negotiation support system which provides functionalities to create negotiation models through settlements' historical information. These models are interpreted as Fuzzy Cognitive Maps (FCM) and the software tests as the convergence of each model. Thus, the system intends to facilitate decision-markers to predict future negotiations behavior and, consequently, improve the chances of an agreement. Besides, this work examines a case study through the lenses of FCM to illustrate real negotiations outcomes and expected value quantifications. The proposal is to compare a model map developed from old negotiations with the results obtained through FCM simulations. As a result, from the use of these mechanisms, negotiators could better visualize alternative ways to improve the chances of successful agreements.

The activities executed in the scientific environment are extremely dependent on knowledge from their performers. Thus, knowledge management initiatives are very important in this environment. One of the possibilities for improving the knowledge flow is to explore past experiences, resulting from the modeling and execution of previous scientific activities and handled by a workflow management system. This work presents Thoth, a system which aims at knowledge reuse in the scientific environment, during the planning, design and execution of scientific activities. This approach is integrated, with a CBR approach, also described in this paper, with workflow systems and the use of ontologies.
