  • Lightweight NLP for Social Media Applications

    by Bruce Smith

    Social media includes lots of free-form textual data in "natural languages", the languages people speak. Natural Language Processing (NLP) helps you analyze that data. Some NLP problems are very hard, but a number of lightweight NLP techniques are available in open-source tools. You can use these to improve your social media applications, even if you're not a computational linguist. In this session, I will introduce some of these techniques and tools, and I will give hints on getting started using NLP in your social media applications. Many NLP techniques require training corpora, sets of annotated documents. I will talk about constructing and maintaining a training corpus. And, I will talk about some of the ways we use NLP at Lithium Technologies.

  • Language Technology and the Clinical Narrative

    by Philip Resnik

    Electronic health records have the potential for enormous good, but in order for them to live up to their full potential, information about patients -- their symptoms, diagnoses, allergic reactions, medical backgrounds, family histories -- must take the form of standardized, structured, easy-to-manipulate data. One obvious way to get there is to tightly structure the way that doctors create the medical record. As a result, physicians are under increasing pressure to abandon unrestricted natural language and the clinical narrative, and turn the medical documentation process into a jungle of pull-down menus, checkboxes, and restricted vocabularies. In this presentation I argue that the results could be catastrophic, I make the case for preserving the clinical narrative, and I argue for a practical way out of the dilemma: using natural language processing technology to produce the structured records we need, while still allowing physicians the freedom of unrestricted clinical language.
