This paper summarizes a model of interaction for CVEs inspired by the process followed in human communication in the real world, detailing both the main elements and the communication process itself. The model proposed copies some properties of the real world communication but also allows the easy integration of Task Analysis to the design of CVEs, helping the developer in the design of the app...

Requirements identification in textual documents or extraction is a tedious and error prone task that many researchers suggest automating. We manually annotated the PURE dataset thus created new one containing both requirements non-requirements. Using this dataset, we fine-tuned BERT model compare results with several baselines such as fastText ELMo. In order to evaluate on semantically more co...

Separating two or more aspects of an object via cutting was likely important factor in the origin and evolution flaked stone technology. In recent years experiments have demonstrated that several tool attributes can influence different kinds behaviour: slicing, cleaving, scraping, sawing, drilling, piercing abrading. Here we experimentally assessed role flake plan- profile-view gross-edge curva...
