أدوات البناء لإزالة المعلومات الحساسة مثل الأسماء الشخصية والعناوين وأرقام الهواتف - ما يسمى بالمعلومات الصحية المحمية (PHI) - من النص الحر الإكلينيكي هي مهمة مهمة لجعل النصوص السريرية متاحة للبحث. يجب تقييم هذه أدوات تحديد الهوية فيما يتعلق بجودتها في شكل دقة القياسات وإعادة الاتصال. لتقييم هذه الأدوات، يجب أن تكون معايير الذهب - النص السريري المشروح - يجب أن تكون متاحة. هذه المعايير الذهبية موجودة لغات أكبر. للنرويجية، ماذا - على الإطلاق، لا توجد هذه الموارد. لذلك، تم تمديد كوربوس الإكلينيكي الاصطناعية النرويجية الموجودة بالفعل، Norsynthclinical، مع فيس ومشروحة من قبل اثنين من الناحيين، والحصول على اتفاقية مشتركة بين المعجبين بقيمة 0.94 F1. في المجموع، يحتوي Corpus على 409 حيلة فاي مشروحة وتسمى Norsynthclinical Phi. تم تطوير وتدريب الأداة الهجينة لإلغاء تحديد (تعلم الآلة والبيانات المستندة إلى القواعد) على النرويجية بالموارد المفتوحة المتاحة، وحصلت على تدبير إجمالي F1 من 0.73 واستدعاء 0.62، عند اختباره باستخدام Norsynthclinicalical Phi. يتم فتح Phi Norsynthclinical Phi ومتاحا في Github لاستخدامها من قبل مجتمع البحث.
Building tools to remove sensitive information such as personal names, addresses, and telephone numbers - so called Protected Health Information (PHI) - from clinical free text is an important task to make clinical texts available for research. These de-identification tools must be assessed regarding their quality in the form of the measurements precision and re- call. To assess such tools, gold standards - annotated clinical text - must be available. Such gold standards exist for larger languages. For Norwegian, how- ever, there are no such resources. Therefore, an already existing Norwegian synthetic clinical corpus, NorSynthClinical, has been extended with PHIs and annotated by two annotators, obtaining an inter-annotator agreement of 0.94 F1-measure. In total, the corpus has 409 annotated PHI instances and is called NorSynthClinical PHI. A de-identification hybrid tool (machine learning and rule-based meth- ods) for Norwegian was developed and trained with open available resources, and obtained an overall F1-measure of 0.73 and a recall of 0.62, when tested using NorSynthClinical PHI. NorSynthClinical PHI is made open and available at Github to be used by the research community.

In this paper, we develop Sindhi subjective lexicon using a merger of existing English resources: NRC lexicon, list of opinion words, SentiWordNet, Sindhi-English bilingual dictionary, and collection of Sindhi modifiers. The positive or negative sent
iment score is assigned to each Sindhi opinion word. Afterwards, we determine the coverage of the proposed lexicon with subjectivity analysis. Moreover, we crawl multi-domain tweet corpus of news, sports, and finance. The crawled corpus is annotated by experienced annotators using the Doccano text annotation tool. The sentiment annotated corpus is evaluated by employing support vector machine (SVM), recurrent neural network (RNN) variants, and convolutional neural network (CNN).
The National Virtual Translation Center (NVTC) seeks to acquire human language technology (HLT) tools that will facilitate its mission to provide verbatim English translations of foreign language audio and video files. In the text domain, NVTC has be
en using translation memory (TM) for some time and has reported on the incorporation of machine translation (MT) into that workflow (Miller et al., 2020). While we have explored the use of speech-totext (STT) and speech translation (ST) in the past (Tzoukermann and Miller, 2018), we have now invested in the creation of a substantial human-made corpus to thoroughly evaluate alternatives. Results from our analysis of this corpus and the performance of HLT tools point the way to the most promising ones to deploy in our workflow.
This paper introduces NorecNeg -- the first annotated dataset of negation for Norwegian. Negation cues and their in-sentence scopes have been annotated across more than 11K sentences spanning more than 400 documents for a subset of the Norwegian Revi
ew Corpus (NoReC). In addition to providing in-depth discussion of the annotation guidelines, we also present a first set of benchmark results based on a graph-parsing approach.
This paper describes a freely available web-based demonstrator called HB Deid. HB Deid identifies so-called protected health information, PHI, in a text written in Swedish and removes, masks, or replaces them with surrogates or pseudonyms. PHIs are n
amed entities such as personal names, locations, ages, phone numbers, dates. HB Deid uses a CRF model trained on non-sensitive annotated text in Swedish, as well as a rule-based post-processing step for finding PHI. The final step in obscuring the PHI is then to either mask it, show only the class name or use a rule-based pseudonymisation system to replace it.
Cross-target generalization is a known problem in stance detection (SD), where systems tend to perform poorly when exposed to targets unseen during training. Given that data annotation is expensive and time-consuming, finding ways to leverage abundan
t unlabeled in-domain data can offer great benefits. In this paper, we apply a weakly supervised framework to enhance cross-target generalization through synthetically annotated data. We focus on Twitter SD and show experimentally that integrating synthetic data is helpful for cross-target generalization, leading to significant improvements in performance, with gains in F1 scores ranging from +3.4 to +5.1.
