background: the extraction of teeth for orthodontic purpose has always been a controversial subject in the speciality. the aesthetics impact of the soft-tissue profile might play a key role in deciding on premolar extraction or non-extraction (ne) treatment, particularly in borderline patients. the purpose of this cephalometric study was to examine the soft-tissue treatment effects of class ii ...
Relation extraction is the task of recognizing and extracting relations between entities or concepts in texts. A common approach is to exploit existing knowledge to learn linguistic patterns expressing the target relation and use these patterns for extracting new relation mentions. Deriving relation patterns automatically usually results in large numbers of candidates, which need to be filtered...
BACKGROUND Recruitment and retention are documented as two of the most difficult elements of conducting clinical trials. These issues are even more challenging in paediatric trials, particularly when the families being recruited and retained are deemed 'hard to reach'. METHODS Through the authors' own reflection on the conduct of the trial this paper examines recruitment and retention with ha...
We describe an approach to classifying images found on the WWW for the purpose of information extraction (IE). Among features used for classification are image sizes, colour histograms, and the similarity of the classified image’s content to images in a training collection. Our content similarity metric is based on the latent semantic index. Results are presented on a collection of 1624 image o...
Relation extraction is the task of recognizing semantic relations among entities. Given a particular sentence supervised approaches to Relation Extraction employed feature or kernel functions which usually have a single sentence in their scope. The overall aim of this paper is to propose methods for using knowledge and resources that are external to the target sentence, as a way to improve rela...
A key challenge introduced by the recent SpaceEval shared task on spatial relation extraction is the identification of MOVELINKs, a type of spatial relation in which up to eight spatial elements can participate. To handle the complexity of extracting MOVELINKs, we combine two ideas that have been successfully applied to information extraction tasks, namely tree kernels and multi-pass sieves, pr...
Dendritic cells (DCs) vaccination is a promising way to contend cancer metastases especially in the case of immunogenic tumors. Unfortunately, it is only rarely possible to achieve a satisfactory clinical outcome in the majority of patients treated with a particular DC vaccine. Apparently, DC vaccination can be successful with certain combinations of features of the tumor and patients immune sy...
as the stage next to that of corneal section and iridectomy in the extraction of a hard cataract; and I believe that this rule is invariably followed by the ophthalmic surgeons of the present day. The modification I propose, and have adopted in all my late cases, is to tear the capsule of the lens as the first preliminary step in the operation for extraction of cataract. The advantages accruing...
