Towards the easy analysis of celebrity representations through instagram: A case study Niklander, S.; Soto, R.; Crawford, B.; De La Barra, C.L.; Olguín, E. This paper focuses on the analysis of celebrity representations through Instagram. We refer to representation of a person as the set of concepts, images, ideas and emotions that this person transmit to the world. Representations transmit useful information for fans, but also for the entities related with the involved person. However, the representation exposed by posted images is hard to automatically process as depend on several variables which are complex to interpret. We propose then to employ discourse analysis in order to facilitate the analysis of such people representations. Discourse analysis is a qualitative and interpretive methodology for analyzing social phenomena through any communication mechanism. We illustrate interesting results where the use of discourse analysis allows us to easily process representations through images.

Towards the easy analysis of mass media audience reaction on social networks via discursive category tools Niklander, S.; Soto, R.; Crawford, B. The Mass Media involves information and communication products targeted to a wide audience. Today such communications products are also available on Internet where people can react to a given information by posting critics, congratulations, opinions or whatever they want via social networks. Such reactions are considered valuable information for instance to government and companies. However, this information is hard to automatically process as people commonly use ironies, stereotypes, metaphors expressed in informal writing plenty of chat abbreviations, emoticons, and slang words. In this paper, we illustrate how tools based on discursive categories can be used to analyze such reactions and thus to process and understand the information behind them.

Optimization for UI design via metaheuristics Soto, R.; Crawford, B.; Almonacid, B.; Niklander, S.; Olguín, E. In recent years, different optimization problems have been arose in the context of UI design. Initially those problems were solved by hand with no computational optimization support since the set of potential design combinations was limited. However, when the space of different possible designs increase, the use of optimization algorithms is mandatory. However, several UI design problems are quadratic, for which guaranteeing the global optimum is not possible in polynomial time. Then the use of classic exact methods may not be feasible. In this paper, we briefly present how metaheuristics can straightforwardly be used to model and solve interesting but complex quadratic problems from UI design. In particular, we employ Cuckoo Search, which is a modern optimization technique to solve a well-known problem concerned to keyboard layout optimization.

Creativity in agile software development methods Crawford, B.; Crawford, K.; Soto, R.; de la Barra, C.L. Creativity is an inherent aspect to the development of new products, therefore a critical capacity for software development. Indicators to measure creativity are grouped into two main areas: (1) those related to the creative result itself and its quality (including novelty and usefulness) and (2) those related to the creative team itself (considering indicators such as individual and group satisfaction, development of cognitive skills, group interaction,…). From this perspective, the aim of this work is to introduce some ideas for assesing the creativity of software products.
