AUTOMATED KEYWORD GENERATION IN THE PUBLIC RADIO SECTOR USING WORD EMBEDDINGS

Public broadcasters find themselves in a difficult situation when it comes to digital offers. In more and more use cases, metadata is needed, e.g. to allow radio editors to search for content pieces, to set up content-based recommendation services, to allow users to browse by categories or tags, or to optimize content for search engines. They are in need of proper metadata to manage digital products and to offer new and timely services. Public broadcasters often have their own taxonomy of keywords at hand. The manual distilling of metadata in particular in form of keywords may however become a bottleneck in operation, whereas automatic keyword generation does not always provide the desired accuracy and also requires continuous human effort for training classifiers and controlling the accuracy. Building upon more recent techniques of word embedding we present a novel approach to assign keywords from a taxonomy to documents on the basis of distributed representation of words and documents that does not require annotation by human experts and evaluate it with a large dataset of a German nation-wide broadcaster. Preliminary results are promising that keywords can be automatically generated in an unsupervised way in the public radio sector

Premature termination, satisfaction with care, and shared decision-making during home treatment compared to inpatient treatment: A quasi-experimental trial

Abstract Background Inpatient equivalent home treatment (IEHT), implemented in Germany since 2018, is a specific form of home treatment. Between 2021 and 2022, IEHT was compared to inpatient psychiatric treatment in a 12-months follow-up quasi-experimental study with two propensity score matched cohorts in 10 psychiatric centers in Germany. This article reports results on the treatment during the acute episode and focuses on involvement in decision-making, patient satisfaction, and drop-out rates. Methods A total of 200 service users receiving IEHT were compared with 200 matched statistical “twins” in standard inpatient treatment. Premature termination of treatment as well as reasons for this was assessed using routine data and a questionnaire. In addition, we measured patient satisfaction with care with a specific scale. For the evaluation of patient involvement in treatment decisions, we used the 9-item Shared Decision Making Questionnaire (SDM-Q-9). Results Patients were comparable in both groups with regard to sociodemographic and clinical characteristics. Mean length-of-stay was 37 days for IEHT and 28 days for inpatient treatment. In both groups, a similar proportion of participants stopped treatment prematurely. At the end of the acute episode, patient involvement in decision-making (SDM-Q-9) as well as treatment satisfaction scores were significantly higher for IEHT patients compared to inpatients. Conclusions Compared to inpatient care, IEHT treatment for acute psychiatric episodes was associated with higher treatment satisfaction and more involvement in clinical decisions

Designing Radio in a Personalized World

Radio broadcasting is currently undergoing major changes. Radio broadcasting agencies experience a shift from the classic linear stream to non-linear personalized playouts on smart devices. Many broadcasting agencies are experimenting how to innovate their offerings, but designing personalized radio is not straightforward. We contribute a design science artefact that considers requirements from different stakeholders – listeners, broadcasting agencies and the public – and present design requirements and design principles with a corresponding architecture for personalized radio

Improving Recall and Precision in Unsupervised Multi-Label Document Classification Tasks by Combining Word Embeddings with TF-IDF

Multi-label document classification is a common task and has become increasingly important for current business needs. However, generating keywords is not easily done as, next to methodological challenges, labeled training data for supervised classification does not always exist in the desired amount or quality. Therefore, methods that do not require labeled training data (e.g., unsupervised learning or statistical approaches) are valuable for practice. As none of these approaches alone provides optimal results in terms of recall and precision, we show that it is worth examining existing approaches for complementary strengths in order to combine them. We found such complementary strengths for an unsupervised word embedding method and the term frequency–inverse document frequency method (tfidf) and propose a combined approach. For evaluation, we test the combined approach on a data set from a public broadcaster in Germany and show that recall and precision can be significantly improved

Implementation, efficacy, costs and processes of inpatient equivalent home-treatment in German mental health care (AKtiV): protocol of a mixed-method, participatory, quasi-experimental trial

Background: Over the last decades, many high-income countries have successfully implemented assertive outreach mental health services for acute care. Despite evidence that these services entail several benefits for service users, Germany has lagged behind and has been slow in implementing outreach services. In 2018, a new law enabled national mental health care providers to implement team-based crisis intervention services on a regular basis, allowing for different forms of Inpatient Equivalent Home Treatment (IEHT). IEHT is similar to the internationally known Home Treatment or Crisis Resolution Teams. It provides acute psychiatric treatment at the user's home, similar to inpatient hospital treatment in terms of content, flexibility, and complexity. Methods/design: The presented naturalistic, quasi-experimental cohort study will evaluate IEHT in ten hospitals running IEHT services in different German regions. Within a multi-method research approach, it will evaluate stakeholders experiences of care, service use, efficacy, costs, treatment processes and implementation processes of IEHT from different perspectives. Quantitative surveys will be used to recruit 360 service users. Subsequently, 180 service users receiving IEHT will be compared with 180 matched statistical 'twins receiving standard inpatient treatment Assessments will take place at baseline as well as after 6 and 12 months. The primary outcome is the hospital re-admission rate within 12 months. Secondary outcomes include the combined readmission rate, total number of inpatient hospital days, treatment discontinuation rate, quality of life, psycho-social functioning, job integration, recovery, satisfaction with care, shared decision-making, and treatment costs. Additionally, the study will assess the burden of care and satisfaction with care among relatives or informal caregivers. A collaborative research team made up of researchers with and without lived experience of mental distress will conduct qualitative investigations with service users, caregivers and IEHT staff teams to explore critical ingredients and interactions between implementation processes, treatment processes, and outcomes from a stakeholder perspective. Discussion: By integrating outcome, process and implementation research as well as different stakeholder perspectives and experiences in one study, this trial captures the various facets of IEHT as a special form of home treatment Therefore, it allows for an adequate, comprehensive evaluation on different levels of this complex intervention
