Google Search Part 2: Querying

1. In databases, a question is called a query.
2. Named after the famous George Boole, boolean operators allow you to combine simple phrases into specific searches using the words AND /OR / NOT.
3. The operator “AND” will bring back only results containing all the words for which you are searching.
4. The operator “NOT,” excludes results (pages) that have the term on them.
5. The Booleans (AND, OR, NOT) combine all your criteria together to find the pages that match all your criteria

The Data Behind Web Sites

11 Vocabulary Words

1. The term Big Data describes the idea that the amount of data we need to deal with is huge and getting bigger in many fields.
2. As a contrast to big data, which is the idea that data is expanding, Big Info is the idea that the amount of consumable media (what we have called info) is also exploding.
3. To anonymize your data, they just unlink the identifier from any personally identifying information (PII). Your info can still be tied together by ID, but not tied back to you…probably.
4. Most web usage data comes from a Web log. This is a piece of software that runs on a server (remember that servers create pages, browsers consume them).
5. To keep track of you, a site can assign you a cookie. It is a unique ID that is tied to your IP address.
6. A heat map allows a company to figure out what parts of a page are more noticed and used than others. The “hotter” an area is the more noticed the area is. For instance, people always scan the tops of pages first. How do they figure out what people are noticing?
7. Bringing all the data together into one place so it can be compared and contrasted is calleddata warehousing.
8. Extracting useful patterns (nuggets of useful info) from large amounts of data through analysis is called data mining.
9. Web Dashboards report various types of data and site statuses (the most popular page, how many people have visited the site, how long people stay on pages, etc.). Think of dashboards of a site like Facebook as a nuclear power control room versus a car dashboard. It contains a sophisticated, differentiated set of indicators.
10. Facebook is data driven. That means that they try to notice everything that users are doing on the site and decide what to do next based on that.
11. The number of users who click on an ad divided by the number who have it on their page is called the click-through rate.

User Interface

13 Vocabulary Words

1. All machines have a way to make them do what they do: their user interface (UI).
2. In speaking of user interfaces, we usually also include the display (banner, navigation, header/footer), decorations (fonts, colors, images, logos), and content (pictures, text, videos, sound).
3. The controls in a UI give you the ability to perform the actions the system allows.
4. It's not always simple. Where's the dividing line between content and control in a text-based hyperlink? One item can be both; the division breaks down pretty quickly.
5. A menu allows the designer to have a lot of commands packed into a small space. However, it also means that things are hidden until the user finds the way to reveal them.
6. A text box allows the user to type free text (whatever you want). Not all text will make sense or work, but you can input it.
7. There are all sorts of controls that we can classify as buttons. When you push them, things happen
8. There are tabs that allow the designer to have a lot of different areas available from a single screen. It is another way of packing a lot of information onto the same screen.
9. On Web pages, links are usually text strings or images that will allow you to click and make something happen. Facebook likes to use them to present abilities to you.
10. Some links allow mouseover behavior. When you hover the mouse above the link, the UI gives you more information about what will happen if you click the link.
11. Some issues with UI: each browser works a bit differently, so any given page might not work as well in some browsers as in others. Often it's difficult to figure out how to make things work cross- platform on different browsers as well as hardware (for example, mobile phones).
12. What works for people in the UI they use is called usability.
13. Greg Badros says: Dogfooding tends to result in suggestions from employees and engineers focusing on power users—it requires a constant push back toward simplicity. It's much more common to design for yourself, but you have to keep in mind what an average user can do and will want to do.
