Auto Insurance

Public auto insurance

Public auto insurance is a government owned and operated system of automobile insuranceoperated in the Canadian provinces of British Columbia, Saskatchewan, Manitoba andQuebec. According to studies by theConsumers' Association of Canada, rates charged for auto insurance in these four provinces are lower than in provinces that use a private auto insurance system.[1] In Quebec public auto insurance is limited to coverage of personal injuries while damage to property is covered by private insurers.[2]Saskatchewan has the oldest public auto insurance system with Saskatchewan Government Insurance being founded in 1945. Manitoba Public Insurance was created in 1971 followed by the Insurance Corporation of British Columbia in 1973 and the Société de l'assurance automobile du Québec in 1977.Other provinces have considered introducing a public auto insurance system. The Ontario New Democratic Party won the 1990 provincial election on a platform that included public auto insurance. After assuming office, Premier Bob Rae appointed Peter Kormos, one of the most vocal proponents of public insurance, as the minister responsible for bringing forward the policy.[3] With the onset of the recession, however, both business and labour groups expressed concern about layoffs and lost revenues.[4] The government rejected the policy in 1991.Public auto insurance has also been considered in New Brunswick after private insurance rates nearly doubled from 2003 to 2005, but was ultimately rejected by the provincial government.[5] It was also an issue in Nova Scotia during its 2003 provincial election and remained in the platform of theofficial opposition, the Nova Scotia New Democratic Party during the 2006 election campaign.[6] However, it did not appear in the NDP platform in the 2009 campaign, and now that the NDP has formed a majority government, it seems unlikely that the party will keep its former promise to introduce a public insurance scheme.[7] Public auto insurance was also under consideration by the Newfoundland and Labrador Progressive Conservative government of Danny Williamsin 2004 as a "last resort" when private insurance firms threatened to pull out of the province in response to legislation rolling back premiums.[8]

Facebook Search

Facebook Graph Search

From Wikipedia, the free encyclopedia
"Graph search" redirects here. For search problems within a general graph, see graph traversal.
Facebook Graph Search feature
Facebook Graph Search is a semantic search engine that was introduced by Facebook in March 2013. It is designed to give answers to user natural languagequeries rather than a list of links.[1] The Graph Search feature combines the big data acquired from its over one billion users and external data into a search engine providing user-specific search results. In a presentation headed by Facebook CEO Mark Zuckerberg, it was announced that the Graph Search algorithm finds information from within a user's network of friends. Additional results will be provided by Microsoft's Bing search engine.[2] In July it was made available to all users using the U.S. English version of Facebook.[3]

Development[edit]

The feature was developed under former Google employees Lars Rasmussen and Tom Stocky.[4]
The Graph Search Features was launched in Beta January 2013 as a limited preview for some English users in the United States.[5][6] Company reports indicate that the service launched to between tens and hundreds of thousands of users. As of August 2013, Graph Search is available to all English users in the US.
The feature has been released only to limited users, with a slow expansion planned. Facebook announced plans for a future mobile interface and the inclusion of Instagram photos.[7]
The name refers to the social graph nature of Facebook, which maps the relationships among users.[8]
In late September 2013, Facebook announced that it would begin rolling out search for posts and comments as part of Graph Search.[9][10] The rollout began in October 2013, but many people who had Graph Search were not given immediate access to this feature.[10][11] A post on the Facebook Engineering blog explained that the huge amount of post and comment data, coming to a total of 700 TB, meant that developing Graph Search for posts was substantially more challenging than the original Graph Search.[12]

Operation[edit]

Graph Search operates by use of a search algorithm similar to traditional search engines such as Google. However, the search feature is distinguished as a semantic search engine, searching based on intended meaning. Rather than returning results based on matching keywords, the search engine is designed to match phrases, as well as objects on the site.[13]
Search results are based on both the content of the user and their friends’ profiles and the relationships between the user and their friends. Results are based on the friends and interests expressed on Facebook, and also shaped by users’ privacy settings. In addition to being restricted from seeing some content, users may be able to view relevant content made publicly available by users that are not listed as friends.[14]
Entries into the search bar are auto-completed as users type, with Facebook suggesting friends and second degree connections, Facebook pages, automatically-generated topics, and finally Web searches for anything Facebook is not yet able to search for.[15]
The operation of the search feature depends on user involvement. The feature is intended to promote users to add more friends, more quickly. In doing so, it can provide updating, more data-rich results and stimulate use of the feature.[16]

Search functions[edit]

Facebook supports searches for the following types:
  • People
  • Pages
  • Places (limitable to a specific location (latitude and longitude) and distance)
  • Check-ins of the user, friends, or where user or friends have been tagged
  • Objects with location information attached. In addition, the returned objects will be those in which the user or friends have been tagged, or those objects that were created by the user or friends.
  • Posts and comments
Users can filter results, such as in time (since and until), or search only a given user's News feed.
The feature also allows users to search the web directly.[17]

Examples[edit]

Tom Stocky of the search team offered several examples of potential queries during the launch presentation, including,
  • “Friends who Like Star Wars and Harry Potter”
  • For setting up a potential date, “Who are single men in San Francisco and are from India”
  • For employee recruiting, “NASA employees who are friends with people at Facebook”
  • For browsing photos or planning travel, “photos of my friends taken at National Parks”[18]
During its roll-out stage, bloggers showed how Facebook Graph Search could be used to uncover potentially embarrassing information (e.g., companies employing people who like racism) or illegal interests (e.g., Chinese residents who like the banned group Falun Gong).[19][20]
Microsoft has been partnered with Facebook to provide search results since 2008. Microsoft Live Search came to be known as Bing following the initiation of the partnership. In 2010, Facebook and Bing partnered to offer socially-oriented search results: ‘People Search’ and ‘Liked by your Facebook Friends’ information appeared in results within Facebook and on Bing.com.[21]
In May 2012, Bing launched a social sidebar feature which displayed Facebook content alongside of search results. Promoted on the basis of asking friends for advice, the feature allows users to broadcast queries related to their searches to Facebook friends, and offers recommendations of Facebook friends, as well as experts from other networks who could be capable of offering insight.[22]
The previously developed Instant Personalization feature integrated friends’ publicly available information, such as likes, into content on other external websites, such as Rotten Tomatoes and Yelp.[23]
The emergence of the Graph Search feature builds on this partnership. Facebook content remains on Bing.com. The focus of Graph Search is internal content, but Bing continues to issue search results of external content. The external search results are based on traditional keyword-match.[24]

Advertising[edit]

In 2012, Facebook introduced sponsored pages in search results. By buying “Targeted Entities” on Facebook, advertisers pay to have their page appear when users search for that entity.[25] Facebook CEO Zuckerberg reported that this will remain a feature of the search feature, but that the advertising component has not been extended in the Graph Search feature.[26]
Criticisms have arisen about the integrity of search results on the basis of ‘buying likes’. This practice refers to situations in which companies, without sponsoring results, accumulate a large number of ‘likes’ through practices such as promotions or paying to operate bot accounts. Critics have argued that this renders results allegedly based on other users’ opinions meaningless.[27]

Open Graph[edit]

The Open Graph feature allows developers to integrate their applications and pages into the Facebook platform, and links Facebook with external sites on the Internet. The feature operates by allowing the addition of metadata to turn websites into graph objects. Actions made using the app are expressed on users’ profile pages.[28]

Privacy[edit]

Initial reactions to the launch of Graph Search included many concerns about privacy.[29][30][31] The social media analytics company Crimson Hexagon reported that 19 percent of users discussing the launch of the feature were stating concerns about privacy.[32] Facebook has alluded to these concerns and emphasized that the search operates within the pre-existing privacy settings: users can access only the information already available to them.[33] The feature makes this information easier and potentially more appealing to find.[34] Related concerns about phishing and the appearance of minors in search results have also been expressed.[35][36][37]
