This chapter, which argues that the structure of the Web reflects the offline world, making it a valuable lens for exploring society, introduces the theories and issues which make general observations about the Web and then provides examples of investigations into particular topics, such as academic web use. The Web offers unique entrée to free information from Wikipedia to news websites and from government information portals to search engines. Moreover, the two broad approaches to investigating society on the Web are reported, which are based around link analysis and Web 2.0 investigations. Web 2.0 has spawned broad research to probe its effect on several aspects of society. The publishing of personal information on the Web, particularly on the social web, appears likely to continue and expand.

Webometric research has fallen into two main categories, namely link analysis and search engine evaluation. Search engines are also used to collect data for link analysis. A set of measurements is proposed for evaluating web search engine performance. Some measurements are adapted from the concepts of recall and precision, which are commonly used in evaluating traditional information retrieval systems. Others are newly developed to evaluate search engine stability, which is unique to web information retrieval systems. Overlapping of search results, annual growth of search results on each search engines, variation of results on search using synonyms are also used to evaluate the relative efficiency of search engines. In this study, the investigator attempts to conduct a webometric study on the topic medical tourism in Kerala using six search engines; these include three general search engines, namely Bing, Google, and Lycos, and three metasearch engines, namely Dogpile, ixquick, and WebCrawler.

During the past decade, the World Wide Web became the most popular network in the World. WWW grows with a very fast speed, thus the information that can be found through it is huge. In the early 90s, the first search engines for the WWW appeared. The user could give some keywords and the system returned a number of URLs (uniform resource locators) that contained the keywords. The order of the URLs in the return list was initially based on the number of the keyword occurrences in each URL. Some more sophisticated systems were taking into account the importance and the frequency of the keywords. As WWW was growing, a simple keyword search could match hundreds of thousands of pages. A human can only check the first twenty or even some more of the URLs that the search engine returns. Consequently, the ordering of the search results became very important. The most important URLs that are related with the search keywords should be ranked first. The link analysis ranking (LAR) is an objective way to sort search results. There are many advantages of the LAR over older methods. First of all the ranking is feasible without getting any feedback from the users. It is also not necessary to store the content of the URLs, but only the links. Another advantage is that it is difficult for the site developers to cheat by repeating keywords in the documents and moreover it may be pre-computed for all URLs. There are even more benefits using LAR to sort the search results that make it the best method used so far.

Problems associated with the improve ment of information retrieval for open environment are considered and the need for it’s semantization is grounded. Thecurrent state and prospects of development of semantic search engines that are focused on the Web information resources processing are analysed, the criteria for the classification of such systems are reviewed. In this analysis the significant attention is paid to the semantic search use of ontologies that contain knowledge about the subject area and the search users. The sources of ontological knowledge and methods of their processing for the improvement of the search procedures are considered. Examples of semantic search systems that use structured query languages (eg, SPARQL), lists of keywords and queries in natural language are proposed. Such criteria for the classification of semantic search engines like architecture, coupling, transparency, user context, modification requests, ontology structure, etc. are considered. Different ways of support of semantic and otology based modification of user queries that improve the completeness and accuracy of the search are analyzed. On base of analysis of the properties of existing semantic search engines in terms of these criteria, the areas for further improvement of these systems are selected: the development of metasearch systems, semantic modification of user requests, the determination of an user-acceptable transparency level of the search procedures, flexibility of domain knowledge management tools, increasing productivity and scalability. In addition, the development of means of semantic Web search needs in use of some external knowledge base which contains knowledge about the domain of user information needs, and in providing the users with the ability to independent selection of knowledge that is used in the search process. There is necessary to take into account the history of user interaction with the retrieval system and the search context for personalization of the query results and their ordering in accordance with the user information needs. All these aspects were taken into account in the design and implementation of semantic search engine "MAIPS" that is based on an ontological model of users and resources cooperation into the Web.

Selain “Song of Myslelf,” makalah ini juga membahas dan membandingkansajak Whitman yang lain, yaitu “For You O Democracy” untuk melihat lebih jauh lagi persepsiWhitman tentang demokrasi. Pembahasan dilakukan dengan melihat aspek pragmatis sajakWhitman dengan merujuk pada Mack (2002). Selain itu, pembahasan juga akan berfokuspada aspek xenofobia dalam karya Whitman dengan merujuk pada salah satu tulisan Price(2004). Simpulan dari pembahasan akan bermuara pada gagasan bahwa konsep utopissemacam demokrasi pun tidak sepenuhnya ideal.

This essay discusses literature learning on the concept of democracy in thepoem. The discussion becomes specific when the concept of democracy in the poem is linkedwith the practice of democracy that occurs currently in America, ever since it is underPresident Trump’s administration. This essay argues that in its practice, the principle ofdemocracy that upholds freedom of speech to every individual, in a dillematic way bringsAmerica to today’s controversial administration by President Trump. Aside From “Songof Myslelf,” this essay also discusses and compares Whitman’s other poem, “For You ODemocracy,” to see further Whitman’s perception on democracy.

The textbook examines the most common diagnostic errors of ophthalmologists when making a clinical diagnosis of "cataract". Clinical examples point to a more critical view of the cataract diagnosis. Due to the fact that most of the errors are based on a superficial examination of the eye, clear recommendations are given for conducting a clinical ophthalmological examination of cataracts. At the same time, special attention is paid to the types of examination of the lens with the help of a slit lamp, to the peculiarities of performing various types of ophthalmoscopy with moderate opacity of optical media.
