Knowledge will Propel Machine Understanding of Content: Extrapolating from Current Examples

Machine Learning has been a big success story during the AI resurgence. One particular stand out success relates to learning from a massive amount of data. In spite of early assertions of the unreasonable effectiveness of data, there is increasing recognition for utilizing knowledge whenever it is available or can be created purposefully. In this paper, we discuss the indispensable role of knowledge for deeper understanding of content where (i) large amounts of training data are unavailable, (ii) the objects to be recognized are complex, (e.g., implicit entities and highly subjective content), and (iii) applications need to use complementary or related data in multiple modalities/media. What brings us to the cusp of rapid progress is our ability to (a) create relevant and reliable knowledge and (b) carefully exploit knowledge to enhance ML/NLP techniques. Using diverse examples, we seek to foretell unprecedented progress in our ability for deeper understanding and exploitation of multimodal data and continued incorporation of knowledge in learning techniques.Comment: Pre-print of the paper accepted at 2017 IEEE/WIC/ACM International Conference on Web Intelligence (WI). arXiv admin note: substantial text overlap with arXiv:1610.0770

Cutting Ties with Pro-Ana: A Narrative Inquiry Concerning the Experiences of Pro-Ana Disengagement from Six Former Site Users.

Websites advocating the benefits of eating disorders (“Pro-Ana”) tend to reinforce and maintain restrictive eating and purging behaviors. Yet remarkably, no study has explored individual accounts of disengagement from these sites and the associated meanings. Using narrative inquiry, this study sought to address this gap. From the interviews of six women, two overarching storylines emerged. The first closely tied disengagement to recovery with varying positions of personal agency claimed: this ranged from enforced and unwelcomed breaks that ignited change, to a personal choice that became viable through the development of alternative social and personal identities. A strong counternarrative to “disengagement as recovery” also emerged. Here, disengagement from Pro-Ana was storied alongside a need to retain an ED lifestyle. With “recovery” being just one reason for withdrawal from Pro-Ana sites, clinicians must remain curious about the meanings individuals ascribe to this act, without assuming it represents a step toward recovery.Peer reviewedFinal Accepted Versio

Problematisation and regulation: bodies, risk, and recovery within the context of Neonatal Abstinence Syndrome

Background Neonatal Abstinence Syndrome (NAS) is an anticipated effect of maternal drug use during pregnancy. Yet it remains a contested area of policy and practice. In this paper, we contribute to ongoing debates about the way NAS is understood and responded to, through different treatment regimes, or logics of care. Our analysis examines the role of risk and recovery discourses, and the way in which the bodies of women and babies are conceptualised within these. Methods Qualitative interviews with 16 parents (9 mothers, 7 fathers) and four focus groups with 27 health and social care professionals based in Scotland. All the mothers were prescribed opioid replacement therapy and parents were interviewed after their baby was born. Data collection explored understandings about the causes and consequences of NAS and experiences of preparing for, and caring for, a baby with NAS. Data were analysed using a narrative and discursive approach. Results Parent and professional accounts simultaneously upheld and subverted logics of care which govern maternal drug use and the assessment and care of mother and baby. Despite acknowledging the unpredictability of NAS symptoms and the inability of the women who are opioid-dependent to prevent NAS, logics of care centred on ‘proving’ risk and recovery. Strategies appealed to the need for caution, intervening and control, and obscured alternative logics of care that focus on improving support for mother-infant dyads and the family as a whole. Conclusion Differing notions of risk and recovery that govern maternal drug use, child welfare and family life both compel and trouble all logics of care. The contentious nature of NAS reflects wider socio-political and moral agendas that ultimately have little to do with meeting the needs of mothers and babies. Fundamental changes in the principles, quality and delivery of care could improve outcomes for families affected by NAS

Emotional Processes in Elaborating a Historical Trauma in the Daily Press

Twentieth century has witnessed several cases of mass traumatization when groups as wholes were ostracized even threated with annihilation. From the perspectives of identity trauma, when harms are afflicted to a group of people by other groups because of their categorical membership, ethnic and national traumas stand out. This paper aims to investigate long-term consequences of permanent traumatization on national identity with presenting a narrative social psychological study as a potential way of empirical exploration of the processes of collective traumatization and trauma elaboration. A Narrative Trauma Elaboration Model has been introduced which identifies linguistic markers of the elaboration process. Newspaper articles (word count = 203172) about a significant national trauma of the Hungarian history, Treaty of Trianon (1920), were chosen from a ninety year time span and emotional expressions of narratives were analysed with a narrative categorical content analytic tool (NarrCat). Longitudinal pattern of data show very weak emotional processing of the traumatic event. Results are discussed in terms of collective victimhood as core element of national identity and its effects on trauma elaboration

Automated Detection of Substance-Use Status and Related Information from Clinical Text

This study aims to develop and evaluate an automated system for extracting information related to patient substance use (smoking, alcohol, and drugs) from unstructured clinical text (medical discharge records). The authors propose a four-stage system for the extraction of the substance-use status and related attributes (type, frequency, amount, quit-time, and period). The first stage uses a keyword search technique to detect sentences related to substance use and to exclude unrelated records. In the second stage, an extension of the NegEx negation detection algorithm is developed and employed for detecting the negated records. The third stage involves identifying the temporal status of the substance use by applying windowing and chunking methodologies. Finally, in the fourth stage, regular expressions, syntactic patterns, and keyword search techniques are used in order to extract the substance-use attributes. The proposed system achieves an F1-score of up to 0.99 for identifying substance-use-related records, 0.98 for detecting the negation status, and 0.94 for identifying temporal status. Moreover, F1-scores of up to 0.98, 0.98, 1.00, 0.92, and 0.98 are achieved for the extraction of the amount, frequency, type, quit-time, and period attributes, respectively. Natural Language Processing (NLP) and rule-based techniques are employed efficiently for extracting substance-use status and attributes, with the proposed system being able to detect substance-use status and attributes over both sentence-level and document-level data. Results show that the proposed system outperforms the compared state-of-the-art substance-use identification system on an unseen dataset, demonstrating its generalisability

Crime scripting: A systematic review

The file attached to this record is the author's final peer reviewed version.More than two decades after the publication of Cornish’s seminal work about the script-theoretic approach to crime analysis, this article examines how the concept has been applied in our community. The study provides evidence confirming that the approach is increasingly popular; and takes stock of crime scripting practices through a systematic review of over one hundred scripts published between 1994 and 2018. The results offer the first comprehensive picture of this approach, and highlights new directions for those interested in using data from cyber-systems and the Internet of Things to develop effective situational crime prevention measures

Older women, intimate partner violence and mental health: a consideration of the particular issues for health and health care practice.

AIMS AND OBJECTIVES: The purpose of this meta-synthesis was to explore qualitative evidence in older women with a history of Intimate partner violence (IPV) and their accounts and experiences of mental health. BACKGROUND: Intimate partner violence significantly impacts the health and wellbeing of women who experience it. However, women who experience intimate partner violence do not form a homogenous group and the effect on older women has not been adequately distinguished. While there is a growing body of evidence to address this deficit, studies to date have tended to concentrate on older women's experiences of intimate partner violence in totality and as such mental health issues have been subsumed as a part of the whole. DESIGN: Meta ethnographic synthesis of qualitative evidence. METHODS: A systematic search of PUBMED, Cumulative Index to Nursing and Allied Health Literature (CINAHL), COCHRANE, Medline and PsycInfo, Sci was completed. The search included articles published up until the end of December 2015. RESULTS: The review identified that intimate partner violence exerts a significant impact on the mental health of older women. Iintimate partner violence for women in later life is inherently complex, especially where the boundaries of violence and vulnerability have been blurred historically both within the intimate partner violence discourse and through provision and practice. CONCLUSIONS: This paper adds to the developing knowledge and understanding of intimate partner violence for older women as a part of the growing body of evidence of the impact of IPV on the health and wellbeing of those who experience abuse more generally. When age and gender intersect with IPV, there are specific implications and health professionals and service providers need to be aware of these This article is protected by copyright.
