Query: Measurement Context Extraction from Text: Discovering Opportunities and
  Gaps in Earth Science   We propose Marve, a system for extracting measurement values, units, and
related words from natural language text. Marve uses conditional random fields
(CRF) to identify measurement values and units, followed by a rule-based system
to find related entities, descriptors and modifiers within a sentence. Sentence
tokens are represented by an undirected graphical model, and rules are based on
part-of-speech and word dependency patterns connecting values and units to
contextual words. Marve is unique in its focus on measurement context and early
experimentation demonstrates Marve's ability to generate high-precision
extractions with strong recall. We also discuss Marve's role in refining
measurement requirements for NASA's proposed HyspIRI mission, a hyperspectral
infrared imaging satellite that will study the world's ecosystems. In general,
our work with HyspIRI demonstrates the value of semantic measurement
extractions in characterizing quantitative discussion contained in large
corpuses of natural language text. These extractions accelerate broad,
cross-cutting research and expose scientists new algorithmic approaches and
experimental nuances. They also facilitate identification of scientific
opportunities enabled by HyspIRI leading to more efficient scientific
investment and research.
