It is also important to determine whether it starts from some existing theories or hypotheses. The research is conducted to prove whether or not these assumptions are true. 1.2.2 Research methods and reasons of chosen them for research purpose After establishing the research problem and what results are wanted, it will define how it will find the answers. Research is a form of collection and interpretation of information that will form the basis of finding answers to questions. The research uses theories and methods that h... ... middle of paper ... ...search process (Kumar, 2011).
Introduction This chapter aims to explain the research methodology carried out throughout the research study. Firstly the selected research design is defined and described. This is followed by an explanation of the research approach and subject paradigm chosen for the research. Subsequently, this chapter focuses on describing the secondary data methodology used in the literature review of the research. Later, the information regarding to the primary data methodology is given.
3.0 RESEARCH METHODOLOGY 3.1 Introduction Research methodology is a set of procedures or methods used to conduct research. Research can be defined as the research for knowledge or any investigations and experiments to establish facts. In this chapter, the researcher discusses further on research methodology used in the current research to achieve the research objectives as previously highlighted in Chapter One. This chapter will discuss on research design, population, sampling design and data collection method. 3.2 Research Design Research design is a model of studies that allow the researcher to investigate the relationship between the dependent and independent variables.
Thus, when attempts are made to classify different kinds of research studies to different design types, they are classified by the kind of research questions they are able to answer. Research designs can be mapped out to the types of research questions (research problem) using four dimensions: 1) empirical versus non-empirical dimension, 2) using primary versus using secondary data, 3) the nature of the data (numerical versus textual data) and 4) the degree of control (structured (laboratory) conditions versus natural field settings) The first dimension, which is relevant to our study, is that of empirical versus non-empirical studies. Empirical studies involve observing and measuring reality, thereby confirming knowledge through direct experience. Non-empirical (theoretical) studies involve developing and exploring theories that account for given data. The second dimension is that of the nature of data used in the study.
The systematic approach concerning overview and the formulation of a theory is also research (Kothari, 2004). Therefore, the objective in this chapter is to indicate how the data would be collected and analysed. The process and methodology of research used to collect the data for this dissertation will be explained in detail in this chapter. 3.2 TYPES OF RESEARCH Research is a process for collecting, analysing and interpreting information to answer the questions. According to Muaz (2013), there are many ways to classify research designs, but sometimes the distinction is simulated and other times different designs are combined.
The way the questionnaire is developed depends of the type of research being studied. Once the data is collected, researchers must analyze the data. The purpose of analyzing data is to obtain usable and useful information. Many techniques are used to analyze data. Three types which have their own types were mentioned above.
"The key idea behind qualitative research is to learn about the problem or issue from participants and engage in the best practices to obtain that information" (Creswell, 2007). The study will use different qualitative data collection techniques and interpret the results by using interpretivism philosophy. In the interpretivism philosophy the research will conduct by reducing bias and therefore enabling the advent of thoughts, viewpoints, and sentiments (Henning 2004). According to (Saunders et al, 2012) there are two widely used research approaches The first research approach is deductive approach and its ground is considering general premises and reached to specific c... ... middle of paper ... ...ying mainly semi-structured in-depth interview with relevant stakeholders. During the interview, notes will be taken and informants will also be tape-recorded when permissions obtained and immediately transcribed using the informants’ own words.
Research methodology on Natural Language Processing: The main aim of this project is to research on the integration of “Natural Language Processing “ and information systems engineering to enhance query retrieval in natural language processing. Defining a research methodology: The definition of research methodology includes two parts: - Research definition - Methodology Research: It is defined as a thorough and organized query or investigation on a particular theme to revise or determine the facts, theories, applications and so on. Methodology: It is a system of methods followed by a particular discipline. Thus, research methodology is the way how a researcher performs research. Uses of research methodology: There are many applications of research methodology.
Theory is defined as a scientific prediction or explanation for what the researcher expects to find. Theories can be used in quantitative, qualitative, or mixed methods research. In quantitative research, researchers often test theories as an explanation for answers to their questions. In qualitative research, the use of theory is much more varied. The inquirer may generate a theory as the final outcome of a study and place it at the end of a project or place it at the beginning and provide a lens to shape what is looked at and the questions asked.
Use of scientific methods Scientific methods refer to calculated research methodology that identifies a problem, provision of relevant data and a process of formulating the hypothesis based on experiments. The scientific method also involves systematic observation and testing of a specific hypothesis. Scientific methods constitute essential science experiments. The systematic methods are, used to determine naturally occurring phenomenon. This is a useful tool in explaining specific questions while maintain the area of focus.
