Formal Distributional Semantics: Introduction to the Special Issue

Formal Semantics and Distributional Semantics are two very influential semantic frameworks in Computational Linguistics. Formal Semantics is based on a symbolic tradition and centered around the inferential properties of language. Distributional Semantics is statistical and data-driven, and focuses on aspects of meaning related to descriptive content. The two frameworks are complementary in the...

Introduction: special issue on cathodoluminescence.

Cathodoluminescence ~CL! microanalysis provides high-sensitivity spectra and high-resolution images associated with impurity and structural defects at the nanoscale and from luminescent materials including minerals, semiconductor, and dielectric/insulating materials. Cathodoluminescence is the non-incandescent emission of light ~photons! emitted from materials excited by an electron beam. CL ph...

and MeSH terms (MeSH Headings). These descriptions are syntactically analyzed and reduced into separate vectors of MeSH terms which are matched against the queries according to Equation 3 (as similarity between expanded and re-weighted vectors). The weights of all MeSH terms are initialized to one while the weights of titles and abstracts are initialized by tf.idf. The similarity between a quer...

Introduction to Special Issue

Although recent frameworks for test validation have emphasized utilization as a key component (e.g. Bachman & Palmer, 2010; Chapelle, 2012; Kane, 1992), what happens in the sometimes messy contexts where assessments are carried out is often not documented. This is perhaps because test developers are more focused on defining and operationalizing test constructs than on issues of implementation. ...
