Finding information online Information literacy lecture Delivered by Dr. U. D. Onuoha
Surrounded by too much information • Beyond what we can process • “Information explosion”, “Information over-abundance”, “information overload”, “Infobesity”. • Consequence= distraction
Develop a focused search strategy Be specific about your information need • Too broad • University education in Nigeria • More specific • Funding university education in Nigeria
Use of keywords “comparison of information seeking using search engines and social networks” might be broken down into: • Information seeking • Use of search engines • Social networks
Phrase searching Retrieves two or more words only when they appear next to each other as a phrase. • use quotation marks around the phrase, e.g. "higher education" • Use phrase searching with care: searching for a phrase could also eliminate useful records. For example, a search for "language teaching" may not find the words "teaching of language".
Link search terms/keywords with AND (+)eg: soccer and injury
Use OR when there are alternative terms to describe your topic. • e.g. woman or female, or when you are interested in either term • e.g. knee or ankle. Records will be retrieved if either (or both) term is present.
Practical example Topic: Effect of television violence on young adults (focused topic) Step 1:Pull out the key words or major concepts • EXAMPLE: television violence young adults Step 2:Create a list of synonyms • Television: TV, movies, cartoons, news. • Violence: guns, murder, rape, gangs, war. • Young adults: teenagers, adolescents, teens, youth. Step 3:Use and (+) (or) where applicable • (television OR TV OR cartoons OR news) AND (violence OR guns OR murder) AND (teenagers OR youth OR adolescents) Step 4: Use phrase searching to tighten your search • “Television violence” + (teenagers or young adults) where you want the exact phrase “television violence” to appear in your search
Using any topic of your choice do a web search using the strategies discussed • To what extent is your search result improved?
