Big Data involves huge quantity of growing data sets with manifold independent sources. Through the fast development of networking, data storage, and the data collection capacity. Big Data are now quickly expanding in all science and engineering domains, as well as physical, biological and biomedical sciences. This data-driven model involves demand-driven aggregation of information sources, mining and analysis, user interest modelling, and security and privacy considerations. We analyze the challenging issues in the data-driven model and also in the Big Data revolution.Keywords

The tremendous growth of Biomedical text mining increases the publications in literature. The task of Information Extraction is to identify the predefined set of concepts in a specific field. It will disregard unwanted irrelevant information’s. And recognizes the specific class of predefined entities, relationships and events. The manual identification of entity and relationships biomedical literature consumes much time and lengthy and laborious task. Automation of entity and relationship extraction addresses this issues. Various approaches are proposed to extract relationship from biomedical literature. This study analyses a range of approaches to automatic extraction of relationships from biomedical literature. It investigates various methods of relation Extraction System based on the working approach of the systems. The study includes the relation extraction approaches like Co-occurrence based approach, pattern based approach, Rule Based approach and machine Learning Based approaches. The outcomes of the systems are compared using the gold standards of text mining such as precision, recall and F-Measure.
