Domain language model adaptation consists in re-estimating probabilities of a baseline LM in order to better match the specifics of a given broad topic of interest. To do so, a common strategy is to retrieve adaptation texts from the Web based on a given domain-representative seed text. In this paper, we study how the selection of this seed text influences the adaptation process and the perform...

We describe and evaluate a new method of automatic seed word selection for unsupervised sentiment classification of product reviews in Chinese. The whole method is unsupervised and does not require any annotated training data; it only requires information about commonly occurring negations and adverbials. Unsupervised techniques are promising for this task since they avoid problems of domain-de...

This paper describes a new method for the three-dimensional (3-D) tracking and the quantification of blood vessels from magnetic resonance angiography (MRA). The approach is based on 3-D geometrical moments and consists of the following steps: (1) interactive selection of 3-D seed points; (2) automatic tracking of the vessels; (3) local computation of both diameter and orientation; (4) renderin...

Active learning has been shown to be effective for reducing human labeling effort in supervised learning tasks, and in this work we explore its suitability for automatic short answer assessment on the ASAP corpus. We systematically investigate a wide range of AL settings, varying not only the item selection method but also size and selection of seed set items and batch size. Comparing to a rand...

Esophageal adenocarcinoma arises from Barrett’s esophagus, which is the most serious complication of gastroesophageal reflux disease. Strategies for screening involve periodic surveillance and tissue biopsies. A major challenge in such regular examinations is to record and track the disease evolution and re-localization of biopsied sites to provide targeted treatments. In this paper, we extend ...

I compared sexual(SX) and hermaphroditic(HA) reproduction schemes within the Penna model[1]. A fixed set of parameters was used, to make the results comparable with recent simulations[2]. I also reproduced the results for a selfemerging dominance[2] in an independant simulation for both hermaphroditic and sexual cases. A variation on partner selection was also implemented, this shifted stable p...

The field of tractography is rapidly developing, and many automatic or semiautomatic algorithms have now been devised to segment and visualize neural white matter fasciculi in vivo. However, these algorithms typically need to be given a starting location as input, and their output can be strongly dependent on the exact location of this "seed point". No robust method has yet been devised for pla...

in order to select the suitable lines of red bean for chahharmahal & bakhtiari province, this experiment was conducted in lordegan & boldaji regions at 2001-2005. at the first year, single plants of local red bean (from lordegan, ardal, boldaji, dastgerd emamzadeh and gandoman regions) were selected at research farm for phenotypic characters, yield and yield components. at the second year, sele...
