On the Evaluation and Comparison of Taggers: The Effect of Noise in Testing Corpora

This paper addresses the issue of {\sc pos} tagger evaluation. Such evaluation is usually performed by comparing the tagger output with a reference test corpus, which is assumed to be error-free. Currently used corpora contain noise which causes the obtained performance to be a distortion of the real value. We analyze to what extent this distortion may invalidate the comparison between taggers or the measure of the improvement given by a new system. The main conclusion is that a more rigorous testing experimentation setting/designing is needed to reliably evaluate and compare tagger accuracies.Comment: Appears in proceedings of joint COLING-ACL 1998, Montreal, Canad

Combination Strategies for Semantic Role Labeling

This paper introduces and analyzes a battery of inference models for the problem of semantic role labeling: one based on constraint satisfaction, and several strategies that model the inference as a meta-learning problem using discriminative classifiers. These classifiers are developed with a rich set of novel features that encode proposition and sentence-level information. To our knowledge, this is the first work that: (a) performs a thorough analysis of learning-based inference models for semantic role labeling, and (b) compares several inference strategies in this context. We evaluate the proposed inference strategies in the framework of the CoNLL-2005 shared task using only automatically-generated syntactic information. The extensive experimental evaluation and analysis indicates that all the proposed inference strategies are successful -they all outperform the current best results reported in the CoNLL-2005 evaluation exercise- but each of the proposed approaches has its advantages and disadvantages. Several important traits of a state-of-the-art SRL combination strategy emerge from this analysis: (i) individual models should be combined at the granularity of candidate arguments rather than at the granularity of complete solutions; (ii) the best combination strategy uses an inference model based in learning; and (iii) the learning-based inference benefits from max-margin classifiers and global feedback

Bioestratigrafía (foraminíferos) del Eoceno de la localidad de Agost (provincia de Alicante)

Se estudian las asociaciones de foraminíferos planctónicos de niveles pertenecientes al Paleoceno superior, Eoceno inferior y Eoceno medio de la columna de Agost (Alicante), elaborándose una bioestratigrafía detallada. Se ha utilizado la biozonación clásica de Bolli (1966) con algunas modificaciones que se discuten en el texto, identificándose las biozonas siguientes: Zona de Morozovella velascoensis, zona de Morozovella subbotinae, zona de Morozovella forrnosa, zona de Morozovella aragonensis, zona de Acarinina angulosa, zona de Hantkenina aragonensis y zona de Globigerinatheka subconglobata. Se señalan las características de cada una de estas biozonas conindicándose las relaciones con los esquemas zonales utilizados por otros autores. Se incluye, por Último, un cuadro con los rangos estratigráficos de todas las especies de forarniníferos planctónicos identificadas

Application of CSWE Competencies in Process of Obtaining CARF Accreditation

Alteri Behavioral Health achieved a 3-year CARF accreditation in July of 2022. This being the highest level of accreditation possible indicates that the agency demonstrated significant conformance to CARF standards and operates in a manner that is beneficial to clients served (CARF, 2022). The intention of this capstone is to demonstrate the application of CSWE competencies to the process undertaken by the interprofessional team to achieve the desired outcome of CARF accreditation. This process involved the development and implementation of agency policies and procedures. These policies and procedures were formulated based on input from the interprofessional team and application of evidence-based research

Tunable BODIPY derivatives amenable to "click" and peptide chemistry

Novel azido- and amino- functionalised fluorescent probes based on the BODIPY framework have been developed. The probes can be easily and cheaply synthesised, exhibit the highly desirable BODIPY fluorescent properties, and are amenable to “click” and peptide chemistry methodologies. These probes provide a stable and readily available tool amenable for the visualisation of both solution and solid supported events

The Broad Line Radio Galaxy J2114+820

In the frame of the study of a new sample of large angular size radio galaxies selected from the NRAO VLA Sky Survey, we have made radio observations of J2114+820, a low power radio galaxy with an angular size of 6'. Its radio structure basically consists of a prominent core, a jet directed in north-west direction and two extended S-shaped lobes. We have also observed the optical counterpart of J2114+820, a bright elliptical galaxy with a strong unresolved central component. The optical spectrum shows broad emission lines. This fact, together with its low radio power and FR-I type morphology, renders J2114+820 a non-trivial object from the point of view of the current unification schemes of radio loud active galactic nuclei.Comment: 6 pages, 5 figures.
