Translation Class Instruction as Collaboration in the Act of Translation

The paper offers an effective way of teacher-student computer-based collaboration in translation class. We show how a quantitative-qualitative method of analysis supported by word alignment technology can be applied to student translations for use in the classroom. The combined use of natural-language processing and manual techniques enables students to ‘co-emerge’ during highly motivated colla...

A class act: conservation of homeodomain protein functions.

Dramatic successes in identifying vertebrate homeobox genes closely related to their insect relatives have led to the recognition of classes within the homeodomain superfamily. To what extent are the homeodomain protein classes dedicated to specific functions during development? Although information on vertebrate gene functions is limited, existing evidence from mice and nematodes clearly suppo...

Improving the Quality of Minority Class Identification in Dialog Act Tagging

We present a method of improving the performance of dialog act tagging in identifying minority classes by using per-class feature optimization and a method of choosing the class based not on confidence, but on a cascade of classifiers. We show that it gives a minority class F-measure error reduction of 22.8%, while also reducing the error for other classes and the overall error by about 10%.

Lefty peptides, derived by MMP2 cleavage, act as a new class of gelatinase A inhibitor.

MMPs are zinc-dependent endopeptidases that are involved in proteolysis of extracellular matrix in both physiological and pathological processes including cancer. MMPs are involved at all stages of tumor progression, including tumor growth, angiogenesis, and metastasis. We recently showed that overexpression of Lefty in cancer cells restrains tumor growth. Here, we show that small forms of Left...
