Boolean retrieval Boolean retrieval also known as "exact match" model is based on Boolean logic in that both the documents to be searched and the user's query are conceived as sets of terms. The Retrieval is based on whether or not the documents contain the query terms (Boolean retrieval, n.d.) Boolean retrieval has the following strengths: 1) It is easy to implement and it is computationally efficient according to Frakes and Baeza-Yates (1992). Hence, it is the standard model for the current large-scale, operational retrieval systems and many of the major on-line information services use it (Information Retrieval Models, n.d.). 2 Frakes and Baeza-Yates (1992) further states that it enables users to express structural and conceptual constraints
It is not a term that can be defined in one sentence like many other words. It has several dimensions, and even a short essay cannot begin to fully address all of the aspects that define professional behavior. The cornerstone of professionalism will always be professional knowledge. Without it, the person cannot even function in the work environment. However, the concept of professionalism goes far beyond providing a service to clients.
Lastly, this chapter aims to provide an explanation of why other theories are not used. As mentioned above, the methodology used to conduct the research is mentioned first. With a qualitative approach a more in depth knowledge can be obtained. Qualitative
The concept of subjectivity can be referred to as the personal opinions and feelings of how someone’s judgment is shaped instead of outside influences, whereas objectivity is related to the concept of ‘truth’, meaning that there is a lack of bias, judgement or prejudice involved in the process. Therefore, the aim of this essay seeks to discuss the difference between subjectivity and objectivity, as an anthropologist. In research, as an anthropologist, subjectivity mainly refers to an individual 's opinions, judgements, emotions, beliefs and even assumptions. This means that it is based upon an individual 's influences or perceptions of a particular interest, within society. A society involves a specific culture.
Fourthly, an outline of a methodological framework should be a part of a research proposal. The methodology should contain an illustration of the population of the study, the number and size of the population, and data collection method used in performing the research project. 9. The research project should be specific, measurable, attainable, realistic, and time-bound in order to be a viable research project. The topic of one’s research project should also be in his/her personal interest because it will be easier to perform, unlike other topics that the researcher doesn’t have an engagement and knowledge
Originally, RSM was developed to model experimental responses (Box and Draper, 1987), and then migrated into the modeling of numerical experiments. The difference is in the type of error generated by the response. In physical experiments, inaccuracy can be due, for example to measurement errors while in computer experiments numerical noise is a result of incomplete convergence of iterative processes, round-off errors or the discrete representation of continuous physical phenomena. In RSM, the errors are assumed to be random. The response can be represented graphically, either in the three-dimensional space or as contour plots that help visualize the shape of the response surface.
The era has witnessed unparalleled growth in the number, availability and importance of images in all directions of life. As the large diversity and huge size of digital image collections have grown exponentially, an efficient image retrieval method is becoming increasingly significant and important too. From large image databases it is difficult to search and retrieve images with traditional text searches because the process of user based annotation has become very tedious and time consuming, as the text often fails to convey the rich structure of images. A prominent content-based retrieval system solves this problem significantly, where the retrieval is based on the automatic matching of the feature of the query image with that of the image database through some image-image similar parameters evaluation. Therefore, images will be indexed based to their own visual content parameters, such as texture, shape and color or any other feature or a combination of set of visual
The last section is resolutely focused on the future since it sheds the light on how the thesis will be ultimately structured. Two separate sections have been added at the end of this preparatory work: the list of works cited and the appendix. The latter comprises the draft work plan for the year to come and a thorough bibliography including the state of my research and what remains to be
The main purpose of this chapter is to provide an outline of the research methods that will be used and to explain the procedures that will be employed to collect the data in the intended study. Since the scope of the study has been determined, and its aim and objectives have also been identified, it is very important to outline the methodology that will be adopted to pursue the issues relating to the research questions. This involves indicating the particular research philosophy and strategic approach that will be assumed by the researcher. Research is a systematic investigation to increase the sum of knowledge (Fellows and Liu, 2003). Marshal and Rossman (2006) define research as a systematic inquiry to provide a better understanding of
