REACH stands for Reading and Assembling Contextual and Holistic Mechanisms from Text. In plain English, REACH is an information extraction system for the biomedical domain, which aims to read scientific literature and extract cancer signaling pathways. REACH implements a fairly complete extraction pipeline, including: recognition of biochemical entities (proteins, chemicals, etc.), grounding them to known knowledge bases such as Uniprot, extraction of BioPAX-like interactions, e.g., phosphorylation, complex assembly, positive/negative regulations, and coreference resolution, for both entities and interactions.
This aims to be a one-stop place for natural language (NL) processors and information extraction (IE) tools. This package includes Odin, our rule-based IE framework. For generic text preprocessing, we currently provide Scala APIs for Stanford’s CoreNLP and maltparser. This package also includes a full-fledged Rhetorical Structure Theory (RST) discourse parser, and a machine learning package containing implementations for common algorithms for both classification and ranking.
Language of Food on Social Media
This project investigates the data-driven connections between the language of food and multiple ommunity characteristics, such as diabetes and overweight rate and geographic locale of authors. We collected a corpus of over three million food-related posts from Twitter. Using these tweets, we built a system that predicts various community characteristics, such as likelihood of a community to be more overweight than average.
