GOOGLE SCHOLAR IS A SPECIALIZED SEARCH ENGINE THAT PROVIDES WHICH OF THE FOLLOWING? PROFESSIONAL

In the meantime, the medical professional is certainly better advised to look for information that has appraised content. In response to this, Curro has suggested a simple methodology to assess the quality of medical information retrieved on the Internet, but the impact of this strategy remains to be seen. But Peterson showed that the generally low skill level for search strategies that most customers have could lead to retrieval of inadequate information, which raises anxiety and decreases compliance. All of these widen the general public's access to high-quality health information. Recently, Google has launched a beta-version of its Google Scholar search engine, Nature Publishing Group has changed its search engine to allow deep penetration, and Elsevier has created another specialised search engine for scientific literature, Scopus, which comes with a cost. Abbott found that the existing general public search engines have a high penetration into even restricted-access data repositories, yielding quality information alternative to traditional primary sources. The advent of the Internet has changed the way both professionals and consumers look for health information. In assessment situations where evaluators can be compared to a gold standard, Relevance Similarity provides an alternative evaluation technique to the commonly used kappa scores, which may give paradoxically low scores in highly biased situations such as document repositories containing large quantities of relevant data. The performance of the retrieval system was not significantly different as a result of the variations in relevance assessment in this particular query set. The similarity comparison among groups showed that a higher degree of agreements exists among evaluators with more subject knowledge. Their assessments were compared to the gold standard assessment, and Relevance Similarities were calculated as the ratio of positive concordance with the gold standard for each topic. They assessed the relevance of retrieved topics obtained by querying a meta-search engine with ten keywords related to medical science. Twelve volunteers were divided into two groups of people according to their domain knowledge. The study was carried out on a collection of Critically Appraised Topics (CATs). In such a setting, Relevance Similarity is the ratio of assessors who rank a given document same as the gold standard over the total number of assessors in the group. In a situation where individual assessment can be compared with a gold standard, this parameter is used to study the effect of such variation on the performance of a medical information retrieval system. The work presented here introduces a new parameter, 'Relevance Similarity', for the measurement of the variation of relevance assessment.

Relevance assessment is a major problem in the evaluation of information retrieval systems.
