| 1 | Define the term search engine. | . | |
| 2 | Distinguish between the surface web and the deep web. | TOK Data is always accessible. | |
| 3 | Outline the principles of searching algorithms used by search engines. | Students will be expected to understand only the principles of the PageRank and HITS algorithms. LINK General principles of computational thinking, connecting computational thinking and program design. |
|
| 4 | Describe how a web crawler functions. | Teachers should be aware of the range of terms that can be associated with web crawlers such as bots, web spiders, web robots. | |
| 5 | Discuss the relationship between data in a meta-tag and how it is accessed by a web crawler. | Students should be aware that this is not always a transitive relationship. TOKData may not always have the intended meaning. |
|
| 6 | Discuss the use of parallel web crawling. | . | |
| 7 | Outline the purpose of web-indexing in search engines. | . | |
| 8 | Suggest how web developers can create pages that appear more prominently in search engine results. | Students will be expected to test specific data in a range of search engines, for example examining time taken, number of hits, quality of returns. | |
| 9 | Describe the different metrics used by search engines. | Students will be expected to test specific data in a range of search engines, for example examining time taken, number of hits, quality of returns. LINK General principles of computational thinking. Connecting computational thinking and program design. S/E, AIM 8 An understanding of search engine metrics could lead to exploitation. |
|
| 10 | Describe the different types of web page. | This should include examples such as personal pages, blogs, search engine pages, forums. | |
| 11 | Explain why the effectiveness of a search engine is determined by the assumptions made when developing it. | Students will be expected to understand that the ability of the search engine to produce the required results is based primarily on the assumptions used when developing the algorithms that underpin it. LINK Connecting computational thinking and program design. |
|
| 12 | Discuss the use of white hat and black hat search engine optimization. | S/E, AIM 8 Developers of search engines should have a moral responsibility to produce an objective page ranking. | |
| 13 | Outline future challenges to search engines as the web continues to grow. | Issues such as error management,lack of quality assurance of information uploaded. AIM 9 Develop an appreciation that search engines will need to evolve to remain effective as the web grows. |
