Lexical bundles are frequent word combinations that commonly appear in different registers. They have been the subject of much research in the area of corpus linguistics during the last decade. While most previous studies of bundles have mainly focused on variations in the use of these word combinations across different registers and a number of disciplines, not much research has been done to e...

We investigate the structures present in the Enron email dataset using singular value decomposition and semidiscrete decomposition. Using word frequency profiles we show that messages fall into two distinct groups, whose extrema are characterized by short messages and rare words versus long messages and common words. It is surprising that length of message and word use pattern should be related...

In this article, we review literature on word learning and propose a theoretical account of how lexical knowledge and word use emerge and develop over time. We contend that the developing lexical system is built on processes that support children's in-the-moment word usage interacting with processes that create long-term learning. We argue for a new characterization of word learning in which si...
