Philip Resnik, PhD, returns to the Psychcast, this time with his research partner and wife, Rebecca Resnik, PsyD, to discuss the interface between language, psychiatry, psychology, and health. Dr. Philip Resnik appeared on the show previously to discuss artificial intelligence, natural language processing, and mental illness. He is a professor in the department of linguistics at the University of Maryland, College Park, and has a joint appointment with the university’s Institute for Advanced Computer Studies. Dr. Philip Resnik has disclosed being an adviser for Converseon, a social media analysis firm; FiscalNote, a government relationship management platform; and SoloSegment, which specializes in enterprise website optimization. Some of the work Dr. Philip Resnik discusses has been supported by an Amazon AWS Machine Learning Research Award. Dr. Rebecca Resnik is a licensed psychologist in private practice who specializes in neuropsychological assessment. In 2014, she served as cofounder of the Computational Linguistics and Clinical Psychology workshop at the North American Association for Computational Linguistics. She continues to serve as a workshop organizer and clinical consultant to the cross-disciplinary community. She has no disclosures. Dr. Norris disclosed having no conflicts of interest. Take-home points Dr. Rebecca Resnik and Dr. Philip Resnik are interested in finding measurable, observable features to apply to the assessment of psychological and psychiatric diagnoses. They point out that finding an objective measure is essential for scaling up mental health evaluations and treatment. Natural language processing (NLP) is focused on analyzing language content. NLP technology has generated tools such as Siri, Alexa, and Google Translate, and NLP allows computers to do things more intelligently with human language. Individuals are using machine learning and NLP to analyze language data sets to evaluate diagnostic criteria. The goal is to create or use language sets that can be analyzed outside of the clinic. Dr. Rebecca Resnik imagines a world where a patient gives a “language sample” to an app or an avatar that would be evaluated by NLP that would, in turn, offer some overarching hypotheses about the person. So much of evaluations is trying to home in on the correct signal, explicit and implicit, from the patient. In addition, neuropsychiatric tests/scales are standardized against a limited scope of the population, so NLP would be matched to the individual. Dr. Philip Resnik looks at signals in text and speech content, acoustics, microexpressions, and even biometric data. Machine learning can process and distill a huge amount of data with various signals more easily than any human. Dr. Rebecca Resnik revisits the idea of clinical white space, which is the “space” or the time between clinical encounters, and this is where decompensation and high-risk suicidal behaviors occur. She suggests that NLP software could be used to fill this white space by using apps to collect text samples from patients, and the software would analyze the samples and warn of patients who are at risk of decompensation or suicide. If clinicians were to use text or speech samples from people’s smart technology, we could assess an individual's risk in the moment and use nudge-type interventions to prevent suicide. Finally, Dr. Philip Resnik emphasizes that there are technologists who have the skills and technology that is on the verge of helping clinicians, but the key to progress is collaborating with clinicians.

Philip Resnik, PhD, joins host Lorenzo Norris, MD, to discuss the use of AI and natural language processing to help clinicians identify patterns in the behaviors of patients with mental illness. Dr. Resnik is a professor in the department of linguistics at the University of Maryland, College Park. He also has a joint appointment with the university’s Institute for Advanced Computer Studies. Dr. Resnik has disclosed being an adviser for Converseon, a social media analysis firm; FiscalNote, a government relationship management platform; and SoloSegment, which specializes in enterprise website optimization. Some of the work Dr. Resnik discusses has been supported by an Amazon AWS Machine Learning Research Award. Dr. Norris disclosed having no conflicts of interest. And don’t miss the “Dr. RK” segment, with Renee Kohanski, MD. Take-home points Artificial intelligence (AI) refers to the effort to get computers to develop capabilities that humans would consider intelligent when people do them. For example, a “smart” thermostat learns patterns of behaviors and changes the temperature accordingly. Natural language processing (NLP), an AI approach, focuses on the content of language from the words used and looks for cues within the content. NLP technology allows computers to do things more intelligently with human language, and NLP has generated technologies such as Siri, Alexa, and Google Translate. Much of clinical work is focused on language, and clinicians look for cues within the content. Dr. Resnik is a technologist who believes that NLP can help facilitate clinical progress, especially in the face of a shortage of mental health clinicians and the limited amount of time that clinicians are able to spend with their patients. Research aimed at using machine learning and NLP to analyze social media and other types of online presence to evaluate for suicide risk and the presence of mood disorders is underway. Dr. Resnik imagines an ecosystem in which computers and humans balance their efforts, with each “brain” doing what they are best at; he believes in technology’s ability to save us time so we can prioritize our efforts. Summary A common example of NLP is automatic dictation and transcription software embedded in medical records. Dr. Resnik thinks of technology as an enabler and augmentation strategy. Resnik and his wife, Rebecca Resnik, PsyD, completed a study using NLP to automatically detect clusters of language in the writing samples of college students. NLP software evaluated the natural patterns of language that might correlate with vegetative and somatic symptoms of depression and social isolation. His team was able to home in on language themes specific to college students that suggest specific symptoms of depression. Another example of NLP in mental health is using predictive modeling, taking in data, and then making a prediction about a pertinent variable to understand mental health outcomes. For example, Glen Coppersmith, PhD, and associates evaluated social media posts with NLP software and concluded that analysis of language in social media posts can accurately identify individuals at risk of suicide and facilitate earlier interventions. Resnik imagines a future in which speech and language samples are used to give a point-of-care evaluation of a patient’s mood and suicide risk. “Clinical white space” is all the “space” (for example, the time between clinical encounters) and this is where decompensation occurs. Resnik suggests that NLP software could be used to fill this white space by using apps to collect text samples from patients. Software would analyze the samples and warn of patients who are at risk of decompensation or suicide. Barriers to using this technology include engaging the technologists and clinicians, and accessing data samples because of privacy concerns, especially because HIPPA was written before the emergence of mega data.

There is a growing awareness that new kinds of science are needed to cope with many contemporary problems. The idea of Science 2.0 shifts attention from the natural to the made world, where richly interdisciplinary problems are resistant to reductionist solutions. Science 2.0 includes topics such as environmental preservation, energy sustainability, conflict resolution, community building, and universal usability. The problems of universal usability have technical foundations, but its intensely human dimensions means that innovative solutions are needed to promote broad usage of the web, mobile technologies, and new media. The goals are to enable broad access to learning, democratic processes, health information, community services, etc. Challenging research problems emerge from addressing the needs of diverse users (novice/experts, young/old, abled/disabled, multiple languages, cross cultural) who use a wide range technologies (small/large displays, slow/fast networks, voice/text/video). In some cases, traditional controlled studies are successful (Science 1.0), but often novel case study ethnographic methods are more effective (Science 2.0).

"n this talk, after briefly reviewing why we should build a good anomaly-based intrusion detection system, we will briefly present twIDS prototypes developed at the Politecnicdi Milanfor network and host based intrusion detection through unsupervised algorithms. We will then use them as a case study for presenting the difficulties in integrating anomaly based IDS systems (as if integrating usual misuse based IDS system was not complex enough...). We will then present our ideas, based on fuzzy aggregation and causality analysis, for extracting meaningful attack scenarios from alert streams, building the core of the first 360 anomaly based IDS. Also, we will introduce some brand new ideas for correlation based on statistical fitting tests."
