Personal memories composed of digital pictures are very popular at the moment. To retrieve these media items annotation is required. During the last years, several approaches have been proposed in order to overcome the image annotation problem. This paper presents our proposals to address this problem. Automatic and semi-automatic learning methods for semantic concepts are presented. The automatic method is based on semantic concepts estimated using visual content, context metadata and audio information. The semi-automatic method is based on results provided by a computer game. The paper describes our proposals and presents their evaluations.

Relevant past events can be remembered when visualizing related pictures. The main difficulty is how to find these photos in a large personal collection. Query definition and image annotation are key issues to overcome this problem. The former is relevant due to the diversity of the clues provided by our memory when recovering a past moment and the later because images need to be annotated with information regarding those clues to be retrieved. Consequently, tools to recover past memories should deal carefully with these two tasks. This paper describes a user interface designed to explore pictures from personal memories. Users can query the media collection in several ways and for this reason an iconic visual language to define queries is proposed. Automatic and semi-automatic annotation is also performed using the image content and the audio information obtained when users show their images to others. The paper also presents the user interface evaluation based on tests with 58 participants.

From 1974 to 1986 the Iberian Peninsula was the arena of major political changes. The process then undertaken was characterized by the transition from two Iberian authoritarian regimes to two democracies, which enabled both countries to join the European Economic Community (EEC) on 1 January 1986. However, the political vicissitudes until full membership of what became the European Union (EU) was achieved were very different and were decisively, although not exclusively, influenced by the fact Portugal was a republic and Spain a monarchy. In Portugal the 1974 revolution took place with consequent shift of the head of state while in Spain the engine of change was precisely the head of state: King Juan Carlos I. It is also true that despite the dangers to democracy (terrorism in Spain and some radicalism in Portugal) both societies supported the political parties committed to the democratic process in elections, which helped avoid tensions that could have defeated the process. Likewise, it is possible to argue that in Spain a plan to achieve democracy within the rule of law (an archetypal transition) was designed by the head of state, while in Portugal there was no pre-established plan – the programme of the Armed Forces Movement (Movimento das Forças Armadas [MFA]) was a weak and precarious compromise between different visions of the road to follow, enabling an intense political struggle that almost led to civil war and a dangerous state of crisis.
