Using syntactic and semantic features for classifying mo- dal values in the portuguese language

This paper presents a study made in a field poorly explored in the Portuguese language – modality and its automatic tagging. Our main goal was to find a set of attributes for the creation of automatic tag- gers with improved performance over the bag-of-words (bow) approach. The performance was measured using precision, recall and F1. Because it is a relatively unexplored field, the study covers the creation of the corpus (composed by eleven verbs), the use of a parser to extract syntac- tic and semantic information from the sentences and a machine learning approach to identify modality values. Based on three different sets of attributes – from trigger itself and the trigger’s path (from the parse tree) and context – the system creates a tagger for each verb achiev- ing (in almost every verb) an improvement in F1 when compared to the traditional bow approach.

Projeto de arquitetura paisagista: Clichy-Batignolles Paris, a resposta a ambições políticas e aos novos desafios urbanos

A cidade resulta de fatores sociais, das políticas urbanas, das dinâmicas económicas e dos valores ambientais, no espaço e no tempo. Compreender a complexidade do seu funcionamento permite ao arquiteto paisagista interagir com ela. O projeto de Clichy-Batignolles, objeto do presente estudo, surge como resposta às problemáticas da cidade, enquanto metrópole de dimensão mundial, de políticas urbanas associadas à competitividade e à atratividade de pessoas e atividades económicas. O projeto integra o parque Martin Luther King senda a referência de desenvolvimento urbano sustentável e ecológico de Paris. A visão metabólica, que o projeto integra, concilia habitação, mobilidade, ecologia, sustentabilidade e experiência de Natureza, que a extensão da aglomeração urbana transformou em necessidade básica. A cidade ecológica impõe-se às politicas urbanas. É neste contexto de crise ambiental, económica e social que a arquitetura paisagista se posiciona no centro dos grandes desafios contemporâneos da evolução das cidades; Abstract: Landscape Architecture Project: Clichy-Batignolles Paris, the answer to policies ambitions and urban new challenges The city is a result social factors, urban policies, economical dynamics and environmental values, in space and time. Understanding the complexity of its mechanism allows the landscape architect to interact with it. The Clichy-Batignolles urban project, the subject of the present study, is a response to the problematic issues of the metropolitan worldwide city, in which competitiveness and attractiveness urban policies are created to attract people and economical activities. The project incorporates the Martin Luther King park and is the reference of ecological and sustainable development in Paris. The metabolic vision of the project conciliates habitation, mobility, ecology, sustainability and Nature experience, which the urban concentration length as transformed in basic living needs. The ecological city is imposed to the megacities urban policies. In this environmental, economic and social crisis context, landscape architecture occupies a center position in the contemporary challenges of cities evolution.
