S'Albufera de Mallorca: a botanical view
Whilst the principal value of S'Albufera is ornithological its botanical importance should not be overlooked. Different criteria are considered to assess its importance including extent, species richness. rarity and potential for education and research. The three main habitats include the marshes, which range from freshwater to saline, open water with a similar gradient, and dunes which include stabilised dunes. The dunes are particularly species rich and many comparable areas have disappeared from many areas around the Mediterranean. S'Albufera needs protection and monitoring, but whilst active management is still being carried out it is not the ideal site to record the ecological effects of global climatic changeAunque el principal valor de S'Albufera sea ornitológico, su relevancia botánica no debe ser descuidada. Se usan diferentes criterios para estimar su importancia incluyendo: extensión, riqueza de especies, presencia de rarezas y potencial educativo y de investiqación. Los tres principales hábitats incluyen marismas, cuya agua oscila entre dulce y salina, aguas libres con un gradiente similar y un sistema dunar que incluye dunas estabilizadas. Las dunas son particularmente ricas y muchas áreas similares del litoral mediterráneo han desaparecido. S'Albufera necesita protección y estudios de seguimiento, sin embargo, mientras aún se este llevando una gestión activa, no es una localidad ideal para registrar los efectos ecológicos del cambio climático global.Encara que el principal valor de S'Albufera es ornitològic, la seva importància botànica no ha d'esser descuidada. S'utilitzen diferents criteris per a estimar la seva valoració: extensió, riquesa específica presència d'espècies rares, potencial educatiu i investigador. Els tres principals hàbitats inclouen aiguamolls de diferent salinitat, aigües lliures amb un gradient similar i un sistema dunar que inclou dunes estabilitzades. Les dunes són particularment riques i moltes àrees comparables han desaparegut en el litoral mediterrani. S'Albufera necessita protecció i anàlisis de seguiment, però, mentre hi hagi encara una gestió activa, no és una localitat ideal per a registrar els efectes ecologics del canvi climàtic global
Building Morphological Chains for Agglutinative Languages
In this paper, we build morphological chains for agglutinative languages by
using a log-linear model for the morphological segmentation task. The model is
based on the unsupervised morphological segmentation system called
MorphoChains. We extend MorphoChains log linear model by expanding the
candidate space recursively to cover more split points for agglutinative
languages such as Turkish, whereas in the original model candidates are
generated by considering only binary segmentation of each word. The results
show that we improve the state-of-art Turkish scores by 12% having a F-measure
of 72% and we improve the English scores by 3% having a F-measure of 74%.
Eventually, the system outperforms both MorphoChains and other well-known
unsupervised morphological segmentation systems. The results indicate that
candidate generation plays an important role in such an unsupervised log-linear
model that is learned using contrastive estimation with negative samples.Comment: 10 pages, accepted and presented at the CICLing 2017 (18th
