Definition: In this task, you are given a part of an article. Your task is to generate headline (title) for this text. Preferred headlines are under fifteen words.
Input: Systematic use of the published results of randomized clinical trials is<lb>increasingly important in evidence-based medicine. In order to collate and<lb>analyze the results from potentially numerous trials, evidence tables are<lb>used to represent trials concerning a set of interventions of interest. An<lb>evidence table has columns for the patient group, for each of the interven-<lb>tions being compared, for the criterion for the comparison (e.g. proportion<lb>who survived after 5 years from treatment), and for each of the results.<lb>Currently, it is a labour-intensive activity to read each published paper<lb>and extract the information for each field in an evidence table. There have<lb>been some NLP studies investigating how some of the features from papers<lb>can be extracted, or at least the relevant sentences identified. However,<lb>there is a lack of an NLP system for the systematic extraction of each item<lb>of information required for an evidence table. We address this need by a<lb>combination of a maximum entropy classifier, and integer linear program-<lb>ming. We use the later to handle constraints on what is an acceptable<lb>classification of the features to be extracted. With experimental results,<lb>we demonstrate substantial advantages in using global constraints (such<lb>as the features describing the patient group, and the interventions, must<lb>occur before the features describing the results of the comparison).
Output:
Extraction of evidence tables from abstracts of randomized clinical trials using a maximum entropy classifier and global constraints
