Web Directory= categorized
listings of webpages created and maintained by humans What is the purpose of an index in a search engine? An index helps search engines efficiently locate relevant pages containing keywords used in a search Page-ranking method most commonly associated with Google's success Certain algorithms In some cases, a search engine may use hundreds of different criteria to determine which pages appear at the top of a SERP. Google, for instance, claims to use over 200 "clues" to determine how it ranks pages Search Engine Optimization (SEO) vs. Pay Per Click (PPC) SEO= to improve their website's organic listings on SERPs. No payments are made to the search engine service for organic search listings.

In addition to keywords and bid pricing for ads, search engines consider... - Geographic location How do webpage factors influence the effectiveness of PPC ads? product ads link --> main page of website, or put item directly in cart Four metrics used to evaluate the effectiveness of PPC advertising campaign - Click through Rates (CTR)= useful for evaluating keyword selection -Keyword Conversion= ? -Cost of Customer Aquisition (CoCa)= total budget of campaign/ number of customers who purchased - Return on Advertising Spending (ROAS)= Revenue/Cost 5 ways semantic technology is enhancing the search experience of users -1. Related searches: (ex: "Did you mean...") (more listed on slides) How do metadata tags facilitate more accurate search results Data is tagged describing the nature of the information, where it came from, and how it is arranged - makes the web a giant database that can be read and used by a variety of
applications 3 evolutionary stages of the internet 1. The Initial Web 2. The Social Web 3. A Semantic Web Context defines the intent of the user; for example, trying to purchase music, to find a job, to share memories with friends and family Personalization refers to the user's personal characteristics that impact how relevant the content, commerce, and community are to an individual. Vertical Search as you have read, focuses on finding information in a particular content area, such as travel, finance, legal, and medical. 3 languages developed by the W3C and associated with the semantic web The semantic Web utilizes additional languages that have been developed by the W3C. These include resource description framework (RDF), Web ontology language (OWL), and SPARQL protocol and RDF query language (SPARQL). How is a recommendation engine different from a search engine Search engine- customers find products through an active search, assuming customers know what they want and how to describe it when forming their search query. Recommendation engines- proactively identify products that have a high probability of being something the consumer might want to buy. Examples of ways recommendation engines are being used (besides e-commerce) Netflix does recommendations of movies for customers similar to movies they already have watched. Collaborative filtering and recommendation engines - purchase history Content based filtering, what does a company need to know about its products Content-based filtering recommends products based on the product features of items the customer has interacted with in the past and the similarity to other products' features. 4 methods used by recommendation systems - Content filtering Hybrid recommendation systems collaborate all 4 Mixed, Cascade, and Compound Hybrids -Mixed hybrid: Results from different recommenders are presented alongside of each other. -Cascade hybrid: Recommenders are assigned a rank or priority. If a tie occurs (with two products assigned the same recommendation value), results from the lower-ranked systems are used to break ties from the higher-ranked systems. -Compound hybrid: This approach combines results from two recommender systems from the same technique category (e.g., two collaborative filters), but uses different algorithms or calculation procedures.

biology Certain endocrine disorders, such as Cushing syndrome, can be caused by excessive secretion of a hormone (in this case, ACTH) by the pituitary gland or by a problem with the endocrine gland itself (in this case, the adrenals). If you determined the ACTH levels of a Cushing patient, how could you tell the difference between a pituitary problem and a primary adrenal problem?

physics Construct a spreadsheet (or other numerical tool) that will reproduce Fig. 41-1, the graph of binding energy per nucleon (in $\mathrm{MeV}$ ) vs. the mass number $A$. Using Appendix F, calculate the binding energy per nucleon for the most stable isotope of each possible mass number $A \geq 2$. [The first few values will be for ${ }_1^2 \mathrm{H},{ }_2^3 \mathrm{He}$ (it is more stable than ${ }_1^3 \mathrm{H}$ ), ${ }_2^4 \mathrm{He},{ }_3^6 \mathrm{Li}$, and ${ }_3^7 \mathrm{Li}$ (since it is more stable than ${ }_4^7 \mathrm{Be}$ ).] To reduce the amount of data, for $A \geq 20$ plot only points for even values of $A$, and plot to a maximum of $A=142$ Verified answer Recommended textbook solutionsInformation Technology Project Management: Providing Measurable Organizational Value5th EditionJack T.

A web crawler is a software program which browses the World Wide Web in a methodical and automated manner. It collects documents by recursively fetching links from a set of starting pages.
What is the role of web crawlers?Web crawlers systematically browse webpages to learn what each page on the website is about, so this information can be indexed, updated and retrieved when a user makes a search query. Other websites use web crawling bots while updating their own web content.
What is a web crawler also called?A web crawler, or spider, is a type of bot that is typically operated by search engines like Google and Bing. Their purpose is to index the content of websites all across the Internet so that those websites can appear in search engine results.
