In the paper we describe enriching Czech WordNet with the derivational relations that in highly inflectional languages like Czech form typical derivational nests (or subnets). Derivational relations are mostly of semantic nature and their regularity in Czech allows us to add them to the Word-Net almost automatically. For this purpose we have used the derivational version of morphological analyzer Ajka that is able to handle the basic and most productive derivational relations in Czech. Using a special derivational interface developed in our NLP Lab we have explored the semantic nature of the selected noun derivational suffixes and established a set of the semantically labeled derivational relationspresently 14. We have added them to the Czech WordNet and in this way enriched it with approx. 30 000 new Czech synsets. A similar enrichment for Princeton WordNet has been reported in its recently released version 3.0, we will comment on the partial similarities and differences.
Abstract. This paper presents an exploitation of the lexicon of verb valencies for the Czech language named VerbaLex. The VerbaLex lexicon format, called complex valency frames, comprehends all the information found in three independent electronic dictionaries of verb valency frames and it is intensively linked to the Czech WordNet semantic network. The NLP laboratory at FI MU Brno develops a deep syntactic analyzer of Czech sentences, the parsing system synt. The system is based on an efficient and fast head-driven chart parsing algorithm. We present the latest results of using the information contained in the VerbaLex lexicon as one of the language specific features used in the tree ranking algorithm for the Best Analysis Selection algorithm, which is a crucial part of the syntactic analyser of free word order languages.
This paper deals with achievements, limitations and pitfalls of developing the Online Czech Proofreader Tool (OCPT). The Tool has been developed in cooperation with the Department of Czech language of the Faculty of Arts of Masaryk University, the Institute of Theoretical and Computational Linguistics of the Faculty of Arts of Charles University, the Czech Language Institute of the Czech Academy of Sciences and Seznam.cz since 2019. The article describes the linguistic data used and tools and modules that constitute the OCPT and indicates the limitations of using an online web-based proofreader tool, especially in areas where mere application of formal rules for language error detection is not sufficient. The article also brings up the drawbacks of developing the OCPT which include occurrence of false-positives.
Psychological trauma is a significant portion of all medical casualties in combat and peacekeeping operations. Significant resources are dedicated to its prevention and treatment, and yet, rates for incidence and recovery basically have remained unchanged over the years. This is particularly evident in chronic, treatment-resistant patients. One of the major difficulties in managing post-traumatic stress disorder (PTSD) is the failure to grasp the meaning of "trauma" for the patient. Practitioners have assumed that the trauma the wounded experiences is the direct effect of the "traumatic event" and no further inquiry is necessary or warranted. Evidence however, points to the contrary, as not all individuals exposed to a traumatic event develop PTSD, and the majority of those who develop symptoms will recover within a relatively short period of time. ' But what about those who do not respond to treatment? There is no clear understanding of the reasons or conditions that adequately explain this outcome. However, it is the author's experience, that individual factors in the context of a specific socio-cultural context set the stage from where the trauma is experienced and lived. Efforts at treatment focusing in targeting symptom relief only will have limited impact. The author will present a review of the literature, his experience treating chronic PTSD patients from various countries including Colombia, Argentina, and the US, and will argue for the need to develop a comprehensive model for its understanding and treatment.
Introduction: The objectives of study on stress of EMS professionals were to analyze the average and individual rates of burnout syndrome symptoms, sources of stress associated with the profession, and the degree of exposition to critical incidents. Two years later, burnout and experience with any psychological intervention technique were analyzed again. Meanwhile, Critical Incident Stress Management (CISM) techniques after critical incidents, according to Mitchell's model, were performed in some organizations' lectures on prevention, communication trainings, consultations concerning professional stress, supervision meetings and debriefings also are offered to professionals within crisis preparedness. Methods: The questionnaire study used a screening test of symptoms of burnout syndrome. Burnout scores of groups from the year 2003 (286 respondents) and from 2005 (597) were compared. Analysis of variance (ANOVA) was used for basic comparison. The General Linear Model (GLM) was used for testing individual factors' influence on burnout symptoms and for comparison for each of four professional groups: physicians, medical nurses, paramedics, and dispatchers. Exposition to critical incidents, and stressful and positive factors associated with profession were analyzed using descriptive statistics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
