NL Seminar- Aligning English Strings with Abstract Meaning Representation Graphs
Fri, Nov 07, 2014 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Nima Pourdamghani, USC/ISI
Talk Title: Aligning English Strings with Abstract Meaning Representation Graphs
Series: Natural Language Seminar
Abstract: We align pairs of English sentences and corresponding Abstract Meaning Representations (AMR), at the token level. Such alignments will be useful for downstream extraction of semantic interpretation and generation rules. Our method involves linearizing AMR structures and performing symmetrized EM training. We obtain 86.5% and 83.1% alignment F score on development and test sets.
Biography: Nima Pourdamghani is a second year Ph.D. student at ISI. He works with Professor Kevin Knight on Abstract Meaning Representation and its application to machine translation

NL Seminar - Machine Reading of the Biomedical Literature: It's All About Data
Fri, Nov 14, 2014 @ 03:00 PM - 04:00 PM

Conferences, Lectures, & Seminars
Speaker: Gully Burns, USC/ISI
Talk Title: Machine Reading of the Biomedical Literature: It's All About Data
Series: Natural Language Seminar
Abstract: Like most scientific disciplines, cancer biology involves performing experiments and interpreting them. At present, most modeling efforts center on trying to bring together collections of interpretations as 'pathway diagrams' but do not attempt to capture the semantics of supporting experimental data. Here, I will describe a new strategic approach for machine reading of scientific articles based on a generic representation of experimental data with explicit examples within the field of cancer biology. I will also discuss this effort in the context of the Abstract Meaning Representation (AMR) and present an informal generative story for your consideration and feedback.
Biography: Gully Burns develops pragmatic biomedical knowledge engineering systems for scientists that provide directly useful functionality in their everyday use and is based on innovative, cutting edge computer science. He was originally trained as a physicist at Imperial College in London before switching to do a Ph.D. in neuroscience at Oxford. He came to work at USC in 1997, developing the 'NeuroScholar' project in Larry Swanson's lab before joining the Information Sciences Institute in 2006. He is now works as project leader in ISI's Information Integration Group.

NL Seminar- Technologies for every language: how machine learning can reach everyone in the world
Thu, Nov 20, 2014 @ 03:00 PM - 04:00 PM

Speaker: Robert Munro, Idibon
Talk Title: Technologies for every language: how machine learning can reach everyone in the world
Series: Natural Language Seminar
Abstract: Speakers of more than 5,000 languages have access to internet and communication technologies. The majority of phones, tablets and computers now ship with language-enabled capabilities like speech-recognition and intelligent auto-correction, and people increasingly interact with data-intensive cloud-based language technologies like search-engines and spam-filters. For both personal and large-scale technologies, the service quality drops or disappears entirely outside of a handful of languages. Speakers of low-resource languages correlate with lower access to healthcare, education and higher vulnerability to disasters. Serving the broadest possible range of languages is crucial to ensuring equitable participation in the global information economy. I will present examples of how natural language processing and distributed human computing are improving the lives of speakers of all the world's languages, in areas including education, disaster-response, health and access to employment. When applying natural language processing to the full diversity of the world's communications, we need to go beyond simple keyword analysis and implement complex technologies that require human-in-the-loop processing to ensure usable accuracy. I will share results that show how for-profit technologies are improving people's lives by providing sustainable economic growth opportunities when they support more languages, aligning business objectives with global diversity.
Biography: Robert Munro is the CEO of Idibon, a company with the objective of providing language technologies for all the world's languages. In past work he has served as Chief Information Officer for the largest solar energy company in Sierra Leone; was the Chief Technology Officer for the largest use of big data technologies to track disease outbreaks globally; worked for the UN High Commission for Refugees in Liberia; lead the crowdsourced response to the 2010 earthquake Haiti; and has helped information processing in disaster response and election monitoring in more than a dozen countries. In current work, Idibon helps everyone from Fortune 500s to disaster response organizations process language data at scale. Outside of work, he has learned about the world's diversity by cycling more than 20,000 kilometers across 20 countries. Robert has a PhD from Stanford University.
