In this position paper, we argue that the classical evaluation on Natural Language Processing (NLP) tasks using annotated benchmarks is in trouble. The worst kind of data contamination happens when a Large Language Model (LLM) is trained on the test split of a benchmark, and then evaluated in the same benchmark. The extent of the problem is unknown, as it is not straightforward to measure. Contamination causes an overestimation of the performance of a contaminated model in a target benchmark and associated task with respect to their non-contaminated counterparts. The consequences can be very harmful, with wrong scientific conclusions being published while other correct ones are discarded. This position paper defines different levels of data contamination and argues for a community effort, including the development of automatic and semi-automatic measures to detect when data from a benchmark was exposed to a model, and suggestions for flagging papers with conclusions that are compromised by data contamination.

The objective of the project is to build a system for the definition and implementation of software development processes based on metamodels. In fact, there are several methodologies that are suitable for software development. It is important to define the information of these methodologies through models so that they can be managed flexibly in the future and improvements can be made. In addition, it is necessary to build a system that establishes a methodology using information from the model for use by development teams in projects. The OpenUP methodology was used for the development of the project and the CCII-N2016-02 standard for the drafting of the project documentation and memory.
