Chapter 10 – Online Information 3.9 – Availability of Information Online and the Use of Online Information There are types of information sources: Primary Source – You own the data. (Photos you have taken, Articles you have written) Secondary Source – Someone else owns the data and you are using it (Radio Program, TV, Books) Search engines are used to allocate relevant web pages. They do this by comparing entered information to records in a database and give the most relevant results. To make the results as accurate as possible: - Use Keywords - Use Search types (specify the type of information you are looking for) - Use Search tools (Tools to help filter the results) - Use Searcy Syntax o AND is (+) o NOT is (-) o PHRASE MATCHING is (“”) Some search engines also use autofill and suggestions. This could either be by closely matching results that are frequently searched, or close to the searches on the database. It could also be depending on the user’s browsing history. The information you use must always be fit for purpose. This means it should be: ✓ Accurate so that it’s not incomplete or false. ✓ Not too old or too new (in terms of historical content) ✓ Relevant to the topic you are searching for. ✓ Reliable, meaning it matches other sources found online. ✓ Not Bias, meaning it looks at both sides of a topic and isn’t prejudice. o You can do this by checking behind statistics used, asking questions regarding the opposing arguments, and checking for reliability as well as missing information. You should also make sure you are aware of the copyright legislation behind the data you use. To avoid plagiarism, you can either: - Credit the source and state that the information isn’t yours - Rephrase it in you own words by understanding the information. - Include URL, Author’s Name and Publication Date Edexcel IGCSE ICT Revision Notes Youssef 1 Koraitem
