Exploring ways beyond the simple supervised learning approach for biological event extraction
نویسندگان
چکیده
Our paper presents the comparison of a machine-learnt and a manually constructed expert-rule-based biological event extraction system and some preliminary experiments to apply a negation and speculation detection system to further classify the extracted events. We report results on the BioNLP’09 Shared Task on Event Extraction evaluation datasets, and also on an external dataset for negation and speculation detection.

Semi-supervised Relation Extraction with Large-scale Word Clustering
We present a simple semi-supervised relation extraction system with large-scale word clustering. We focus on systematically exploring the effectiveness of different cluster-based features. We also propose several statistical methods for selecting clusters at an appropriate level of granularity. When training on different sizes of data, our semi-supervised approach consistently outperformed a st...
متن کاملRe-examining Automatic Keyphrase Extraction Approaches in Scientific Articles
We tackle two major issues in automatic keyphrase extraction using scientific articles: candidate selection and feature engineering. To develop an efficient candidate selection method, we analyze the nature and variation of keyphrases and then select candidates using regular expressions. Secondly, we re-examine the existing features broadly used for the supervised approach, exploring different ...
متن کاملFiltering large-scale event collections using a combination of supervised and unsupervised learning for event trigger classification
BACKGROUND Biomedical event extraction is one of the key tasks in biomedical text mining, supporting various applications such as database curation and hypothesis generation. Several systems, some of which have been applied at a large scale, have been introduced to solve this task. Past studies have shown that the identification of the phrases describing biological processes, also known as trig...
