Query Expansion of Zero-Hit Subject Searches: Using a Thesaurus in Conjunction with NLP Techniques

The focus of our study is zero-hit queries in keyword subject searches and the effort of increasing recall in these cases by reformulating and, then, expanding the initial queries using an external source of knowledge, namely a thesaurus. To this end, the objectives of this study are twofold. First, we perform the mapping of query terms to the thesaurus terms. Second, we use the matched terms to expand the user’s initial query by taking advantage of the thesaurus relations and implementing natural language processing (NLP) techniques. We report on the overall procedure and elaborate on key points and considerations of each step of the process

Pengaruh Retail Mix terhadap Kepuasan Pelanggan pada Foodmart Primo Lippo Mall Kuta

A strategy that retail businesspeople can use to win the competition is by applying the right retail mix strategy.

Early Interferon-γ Production in Human Lymphocyte Subsets in Response to Nontyphoidal Salmonella Demonstrates Inherent Capacity in Innate Cells

Background Nontyphoidal Salmonellae frequently cause life-threatening bacteremia in sub-Saharan Africa. Young children and HIV-infected adults are particularly susceptible. High case-fatality rates and increasing antibiotic resistance require new approaches to the management of this disease. Impaired cellular immunity caused by defects in the T helper 1 pathway lead to intracellular disease with Salmonella that can be countered by IFNγ administration. This report identifies the lymphocyte subsets that produce IFNγ early in Salmonella infection. Methodology Intracellular cytokine staining was used to identify IFNγ production in blood lymphocyte subsets of ten healthy adults with antibodies to Salmonella (as evidence of immunity to Salmonella), in response to stimulation with live and heat-killed preparations of the D23580 invasive African isolate of Salmonella Typhimurium. The absolute number of IFNγ-producing cells in innate, innate-like and adaptive lymphocyte subpopulations was determined. Principal Findings Early IFNγ production was found in the innate/innate-like lymphocyte subsets: γδ-T cells, NK cells and NK-like T cells. Significantly higher percentages of such cells produced IFNγ compared to adaptive αβ-T cells (Student's t test, P<0.001 and ≤0.02 for each innate subset compared, respectively, with CD4+- and CD8+-T cells). The absolute numbers of IFNγ-producing cells showed similar differences. The proportion of IFNγ-producing γδ-T cells, but not other lymphocytes, was significantly higher when stimulated with live compared with heat-killed bacteria (P<0.0001). Conclusion/Significance Our findings indicate an inherent capacity of innate/innate-like lymphocyte subsets to produce IFNγ early in the response to Salmonella infection. This may serve to control intracellular infection and reduce the threat of extracellular spread of disease with bacteremia which becomes life-threatening in the absence of protective antibody. These innate cells may also help mitigate against the effect on IFNγ production of depletion of Salmonella-specific CD4+-T lymphocytes in HIV infection

Divergent Principles of Politeness in Verbal and Non-Verbal Directive Speech Act

This study was conducted aiming at examining: (1) the divergent principles of politeness in students\u27 directive speech act (2) factors affecting politeness and impoliteness in verbal and non-verbal directive speech act produced by students at grade X in Senior High School 1 Mataram in the learning process. The subject of this study are teachers teaching Bahasa Indonesia, English, Economy, History, Math, Religion, Civic, and Science, and all students at Grade X of Science 1, Science 3 and Social 2 in Senior High School 1 Mataram. This study is a descriptive qualitative research. The data source in this study is the number of utterances produced by students and teachers in the learning process. The data were collected through observation. This study revealed that: (1) there were divergent principles of politeness in participants\u27 directive speech act namely single and multiple divergent principles of politeness affected by speaker intentionally accused addressees, intentionally uttered by neglecting the context, was protective to other arguments, showed emotional feeling, given critiques in impolite words and mocked at other; and (2) there were factors affecting politeness and impoliteness in verbal and non-verbal directive speech act produced by students in learning process namely linguistic factor and non-linguistic factor
