This paper describes the UPC participation in the WMT 12 evaluation campaign. All systems presented are based on standard phrasebased Moses systems. Variations adopted several improvement techniques such as morphology simplification and generation and domain adaptation. The morphology simplification overcomes the data sparsity problem when translating into morphologicallyrich languages such as ...

This paper describes our experiments on the Geographical Query Parsing pilot-task for English at GeoCLEF 2007. Our system uses some modules of a Geographical Information Retrieval system presented at GeoCLEF 2006 [3] and modified for GeoCLEF 2007. The system uses deep linguistic analysis and Geographical Knowledge to perform the task.

This paper describes our Georeferencing approaches, experiments, and results at the MediaEval 2011 Placing Task evaluation. The task consists of predicting the most probable geographical coordinates of Flickr videos. Our approaches used only Flickr users textual annotations and tagsets to predict. We used three approaches for this task: 1) a Geographical Knowledge approach, 2) an Information Re...

This paper describes our experiments in Geographical Information Retrieval (GIR) in the context of our participation in the GeoCLEF 2006 Monolingual English task. The TALPGeoIR system follows a similar architecture of the GeoTALP-IR system presented at GeoCLEF 2005 [2] with some changes in the Retrieval modes and the Geographical Knowledge Base. The system has four phases performed sequentially...

This paper describes our experiments on Textual Entailment in the context of the Fourth Recognising Textual Entailment (RTE-4) Evaluation Challenge at TAC 2008 contest. Our system uses a Machine Learning approach with AdaBoost to deal with the RTE challenge. We perform a lexical, syntactic, and semantic analysis of the entailment pairs. From this information we compute a set of semantic-based d...

Desde o fim de 2019, Coronavírus veio a causar um estado pandêmico alerta, que fez com mundo adotasse medidas proteção visando redução da propagação do vírus. Tal fato, atravessou sociedade em toda sua dimensão biopsicossocial, incluindo no âmbito educacional. Considerando fenômeno das Representações Sociais, bem como sistema comunicação estabelecido atualmente, presente trabalho tem objetivo i...

BACKGROUND Permeability characteristics and sensitivity to osmotic shock are principal parameters that are important to derive procedures for the successful cryopreservation of mammalian oocytes. METHODS AND RESULTS The osmotically inactive volume of rhesus monkey oocytes was determined by measuring their volumes in the presence of hypertonic solutions of sucrose from 0.2 to 1.5 mol/l, compar...

A co-culture system using a suspension of detached bovine oviducal epithelial cells (BOEC) has been developed as an effective culture method for supporting the development of bovine embryos derived from oocytes matured and fertilized in vitro. Four commercially available culture media (Waymouth's, Ham's F-10, TCM 199 and Ménézo's B2) supplemented with 10% oestrous cow serum, and a modified Tyro...

This study was designed to investigate the characteristics of acrosomal changes during capacitation of bovine spermatozoa in relationship to in vitro fertility of individual bulls. Motile spermatozoa were separated from frozen-thawed semen by a swim-up procedure and capacitated in IVF-TALP medium with or without heparin. The spermatozoa were evaluated in terms of acrosomal changes at 0, 3, 4, 5...
