Web Search�Engines

Search Engines
Everyone know the Google search engine, but what other search engines are there?
Search Engines
DuckDuckGo
DuckDuckGo
DuckDuckGo presents itself as “Privacy – simplified“.
The site claims that it does not collect data of people using it.
DuckDuckGo
As a consequence, the results on a search are independent on who is searching.
Technically it is a combination of a meta search engine and a web crawler.

DuckDuckGo
The name goes back to a childrens’ game by the name of Duck Duck Goose.
The site is run by a small company in the USA.
Ecosia
Ecosia
Ecosia
Ecosia is run by a small company in Berlin, Germany.
It focusses on a sustainable, ecological mission: 80 per cent of its profits are claimed to go into reforestation projects in Africa and elsewhere.
Ecosia
According to the company, the number of trees planted through their financing was 40 million in October 2018.
Technology-wise, the search results are taken from Bing.
Ecosia
The company in Berlin received various startup awards.
MetaGer
MetaGer
MetaGer is a meta-search engine. It uses the results of many (in this case: up to 60) different search engines, filtering these results in a meaningful way.
MetaGer
In addition, MetaGer has its own crawlers and indexers (like DuckDuckGo).
MetaGer is a university project (started in 1996) by Hannover University in Germany (that’s a university with a focus on technology).
MetaGer
In 2012 they created an association (NGO), the Association for free Access to Knowledge“ to help maintain the project.
Since 2013, MetaGer is available also in English.
MetaGer
MetaGer has a very high level of privacy for the user.
Qwant
Qwant
Qwant
Qwant is a search engine that respects privacy. For example, cookies are deleted with the end of the session.
Qwant
It is based in France (a small company), and recent data said that about 65 per cent of its use are from French users.
Qwant
In independent tests, search results of Google, Bing, DuckDuckGo and Qwant turned out to be of similar quality.
Wolfram|Alpha
Wolfram|Alpha
Wolfram|Alpha
WolframAlpha is a complex search engine, sometimes called a computational knowledge engine or answer engine.
Wolfram|Alpha
It answers factual queries directly by computing the answer from externally sourced data and works out problems in maths, science, media, and everyday life.
Wolfram|Alpha
Users submit queries and computation requests via a text field. WolframAlpha then computes answers and relevant visualizations from a knowledge base of curated, structured data that come from other sites and books.
Closed Captioning
Closed
Captioning
Accessible Video Searching
Closed captioning = Subtitles + Additional Info
So closed captioning isn’t just the dialogue but also other relevant parts of the soundtrack – describing background noises, phones ringing and other audio cues that need to be included to fully understand the video.
Google has a video searching tool, which will search for videos over the entire web, using this link: https://www.google.com/advanced_video_search, and you can choose to search only for closed captioned videos, by selecting the following options:
“Subtitles > closed captioned only”.
Youtube
To search for videos with proper closed captioning on YouTube (not just the auto generated closed captioning, which can sometime be inaccurate), type in your search term and add in “, cc”.
Thanks!
