Opinion Mining and Sentiment Analysis of Online Drug Reviews as a Pharmacovigilance Technique

Pharmacovigilance is the science that focuses on identification and characterization of adverse effects of medications in populations when released to market. The focus of this paper is to study the prospects of exploiting drug related online reviews contributed by social media groups for finding the adverse effects of drugs using opinion mining and sentiment analysis. The experiences and opinions related to drug adverse reactions by patients or other contributors in these forums can be mined and analyzed as a facilitator for pharmacovigilance. This review paper highlights the usability of opinion mining and sentiment analysis as one of the approaches for pharmacovigilance. DOI: 10.17762/ijritcc2321-8169.150711

A Survey of Biological Entity Recognition Approaches

There has been growing interest in the task of Named Entity Recognition (NER) and a lot of research has been done in this direction in last two decades. Particularly, a lot of progress has been made in the biomedical domain with emphasis on identifying domain-specific entities and often the task being known as Biological Named Entity Recognition (BER). The task of biological entity recognition (BER) has been proved to be a challenging task due to several reasons as identified by many researchers. The recognition of biological entities in text and the extraction of relationships between them have paved the way for doing more complex text-mining tasks and building further applications. This paper looks at the challenges perceived by the researchers in BER task and investigates the works done in the domain of BER by using the multiple approaches available for the task

Ontology Building: An Integrative View of Methodologies

Ontologies are being developed and used in many disciplines now a day and they have become a key tool of data integration and knowledge representation in different domains of interest. The ontology building process identifies the stages through which the ontology should go through during its development. There is a certain set of activities to be performed in each stage of the ontology development process and different methodologies have been proposed by researchers for formalizing the different stages. The present paper investigates the most representative methodologies used in the ontology development to look at the different activities that are performed during the process of ontology development. The paper further attempts to provide an integrative view of the most representative methodologies used in the ontology development to look at the set of different activities that can be performed during the process of the ontology development.
