Usage Data

	Usage Data Usage data is the most effective way of evaluating the true relevancy and value of a website. For example, if users arrive on a web site and go back immediately (high bounce rate), chances are that it wasn’t relevant to their query in the first place. However, if a user repeatedly visits a web site and spends a long time on the site, there is a high likelihood that it is extremely relevant. When it comes to search engines, relevant valuable sites get promoted while irrelevant sites get demoted. Search engines want their results to be highly relevant to web users to make sure that web users keep returning to the search engine for future searches. And the best way to establish relevance Relevance is the concept of one topic being connected to another topic in a way that makes it useful to consider the second topic when considering the first.

The concept of relevance is studied in many different fields, including cognitive sciences, logic, and library and information science. Most fundamentally, however, it is studied in epistemology (the theory of knowledge). Different theories of knowledge have different implications for what is considered relevant and these fundamental views have implications for all other fields as well. Definition "Something (A) is relevant to a task (T) if it increases the likelihood of accomplishing the goal (G), which is implied by T." (Hjørland & Sejer Christensen, 2002). A thing might be relevant, a document or a piece of information may be relevant. The basic understanding of relevance does not depend on whether we speak of "things" or "information". For example, the Gandhian principles are of great relevance in today's world. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Web Search Query A web query or web search query is a query that a user enters into a web search engine to satisfy their information needs. Web search queries are distinctive in that they are often plain text and boolean search directives are rarely used. They vary greatly from standard query languages, which are governed by strict syntax rules as command languages with keyword or positional parameters. Types There are three broad categories that cover most web search queries: informational, navigational, and transactional. These are also called "do, know, go." Although this model of searching was not theoretically derived, the classification has been empirically validated with actual search engine queries. * Informational queries – Queries that cover a broad topic (e.g., ''colorado'' or ''trucks'') for which there may be thousands of relevant results. * Navigational queries – Queries that seek a single website or web page of a single entity (e.g., ''youtube'' or ''delta air lines''). * Tra ...
