Abstract(s)

In the present days there is a great need for information that is reliable, consistent and easy to understand, that need is getting bigger and bigger with the course of time. The fact is that most of the information we need is already present in digital form, whether in the web or in documents owned by the user, the hard task is to get that relevant information, organize, process and deliver it to the user so that he can easily understand and create reasoned meaning. In this master thesis those steps are studied, whilst the i2miner application is being built, basing each step of is implementation on the research of themes like, information retrieval, interface design, visualization information and visual analysis. Each of those steps has its associated difficulties, since the implementation of the application is a joint effort with another student, in this thesis i will only address themes like interface design, visualization information, and visual analysis, the information retrieval and processing, will be in charge of José Nelson (PhD student). The appearance of larger screens, faster processors and new algorithms makes possible to produce information from gigabytes of data at stunning speeds, and now it’s possible to create increasingly adapted visualizations to humans. Is therefore important to know the capabilities of humans, like the human sight and human reasoning. This application is made for users who are grounded in economy, and that are many times requested to make important decisions. So the interface of the application must allow the user to rapidly get all the information he needs from reliable sources (that the user thrusts) and make its reasoning, in order to get sufficient and reasoned knowledge to make decisions.
