Google announced Knowledge Graph on May 16, 2012, as a way to significantly enhance the value of information returned by Google searches. Initially only available in English, the Knowledge Graph was expanded in December 2012 to Spanish, French, German, Portuguese, Japanese, Russian, and Italian. Support for Bengali was added in March, 2017.
谷歌在2012年5月16日宣布知识图谱，作为一种显著提高谷歌搜索返回的信息价值的方式。最初只有英语版本，2012年12月知识图谱扩展到西班牙语、法语、德语、葡萄牙语、日语、俄语和意大利语。2017年3月增加了对孟加拉语的支持。

It was reported that its main ability over the Knowledge Graph was to gather information automatically rather than relying on crowd sourced facts compiled by humans; by the time of the 2014 report, it had collected over 1.6 billion facts, 271 million of which were considered "confident facts", a term for information deemed more than 90% true.
In August 2014, New Scientist reported that Google had launched Knowledge Vault. After publication, Google reached out to Search Engine Land to explain that Knowledge Vault was a research paper, not an active Google service, and in its report, Search Engine Land referenced indications by the company that "numerous models" were being experimented with to examine the possibility of automatically gathering meaning from text. The Knowledge Vault was meant to deal with facts, automatically gathering and merging information from across the Internet into a knowledge base capable of answering direct questions, such as "Where was Madonna born". It was reported that its main ability over the Knowledge Graph was to gather information automatically rather than relying on crowd sourced facts compiled by humans; by the time of the 2014 report, it had collected over 1.6 billion facts, 271 million of which were considered "confident facts", a term for information deemed more than 90% true.
2014年8月，《新科学家》杂志报道说，谷歌已经启动了知识库。发表后，谷歌联系了 Search Engine Land，解释说知识库是一篇研究论文，不是谷歌的活跃服务，在其报告中，Search Engine Land 引用了该公司的一些迹象，即正在试验“多种模型” ，以检验从文本中自动收集意义的可能性。知识库旨在处理事实，自动收集并整合来自互联网的信息，形成一个能够直接回答诸如“麦当娜出生在哪里”等问题的知识库。据报告，它在知识图谱方面的主要能力是自动收集信息，而不是依靠人为汇编的众包事实; 截至2014年报告时，它已收集了16亿多事实，其中2.71亿被视为”确信事实” ，这个术语指的是被认为超过90% 正确的信息。
== Criticism ==
=== Lack of source attribution ===
By May 2016, knowledge boxes were appearing for "roughly one-third" of the estimated 100 billion monthly searches the company processed. Dario Taraborelli, head of research at the [[Wikimedia Foundation]], told ''[[The Washington Post]]'' that Google's omission of sources in its knowledge boxes "undermines people’s ability to verify information and, ultimately, to develop well-informed opinions". The publication also reported that the boxes are "frequently unattributed", such as a knowledge box on the age of actress [[Betty White]], which is "as unsourced and absolute as if handed down by God".<ref>{{cite web |first=Caitlin |last=Dewey |title=You probably haven’t even noticed Google’s sketchy quest to control the world’s knowledge |url=https://www.washingtonpost.com/news/the-intersect/wp/2016/05/11/you-probably-havent-even-noticed-googles-sketchy-quest-to-control-the-worlds-knowledge/ |website=[[The Washington Post]] |date=May 11, 2016 |accessdate=December 10, 2017}}</ref>

The publication also reported that the boxes are "frequently unattributed", such as a knowledge box on the age of actress Betty White, which is "as unsourced and absolute as if handed down by God".
到2016年5月，在该公司每月处理的约1000亿次搜索中，“大约三分之一”的知识盒出现了。维基媒体基金会的研究主管 Dario Taraborelli 告诉《华盛顿邮报》 ，谷歌在其知识库中遗漏信息来源，“损害了人们核实信息的能力，并最终形成消息灵通的观点”。该出版物还报道称，这些盒子“经常不具名” ，比如一个关于女演员贝蒂 · 怀特年龄的知识盒，“来源不明，绝对无误，就像上帝传下来的一样”。
=== Declining Wikipedia article readership ===
According to ''[[The Register]]'', the implementation of direct answers in Google search results has caused significant readership declines for the online encyclopedia [[Wikipedia]], from which the Knowledge Graph obtains some of its information.<ref>{{cite web |first=Andrew |last=Orlowski |title=Google stabs Wikipedia in the front |url=https://www.theregister.co.uk/2014/01/13/google_stabs_wikipedia_in_the_front |website=[[The Register]] |date=January 13, 2014 |accessdate=December 10, 2017}}</ref> ''[[The Daily Dot]]'' noted in 2014 that "Wikipedia still has no real competitor as far as actual content is concerned. All that's up for grabs are traffic stats. And as a nonprofit, traffic numbers don't equate into revenue in the same way they do for a commercial media site". After the article's publication, a spokesperson for the [[Wikimedia Foundation]], which operates Wikipedia, stated that it "welcomes" the Knowledge Graph functionality, that it was "looking into" the traffic drops, and that "We've also not noticed a significant drop in search engine referrals. We also have a continuing dialog with staff from Google working on the Knowledge Panel".<ref>{{cite web |first=Joe |last=Kloc |title=Is Google accidentally killing Wikipedia? |url=https://www.dailydot.com/news/wikipedia-falling-traffic-meaning/ |website=[[The Daily Dot]] |date=January 8, 2014 |accessdate=December 10, 2017}}</ref>

据《登记册》报道，谷歌搜索结果中直接答案的使用导致在线百科全书维基百科的读者人数明显下降，知识图谱从中获取了一些信息。《每日点报》在2014年指出，“就实际内容而言，维基百科仍然没有真正的竞争对手。所有这些都是交通统计数据。而且作为一个非营利组织，流量数字并不像商业媒体网站那样等同于收入。”。这篇文章发表后，运营维基百科的维基媒体基金会发言人表示，他们“欢迎”知识图谱功能，正在“调查”流量下降的情况，并且“我们也没有注意到搜索引擎推荐数量的显著下降。我们还与谷歌知识小组的工作人员不断进行对话”。

In August 2014, ''[[New Scientist]]'' reported that Google had launched '''Knowledge Vault'''.<ref>{{cite web |first=Hal |last=Hodson |title=Google’s fact-checking bots build vast knowledge bank |url=https://www.newscientist.com/article/mg22329832-700-googles-fact-checking-bots-build-vast-knowledge-bank/ |website=[[New Scientist]] |date=August 20, 2014 |accessdate=December 10, 2017}}</ref> After publication, Google reached out to ''[[Search Engine Land]]'' to explain that Knowledge Vault was a research paper, not an active Google service, and in its report, ''Search Engine Land'' referenced indications by the company that "numerous models" were being experimented with to examine the possibility of automatically gathering meaning from text.<ref>{{cite web |first=Greg |last=Sterling |title=Google "Knowledge Vault" To Power Future Of Search |url=https://searchengineland.com/google-builds-next-gen-knowledge-graph-future-201640 |website=[[Search Engine Land]] |date=August 25, 2014 |accessdate=December 10, 2017}}</ref> The Knowledge Vault was meant to deal with facts, automatically gathering and merging information from across the Internet into a knowledge base capable of answering direct questions, such as "Where was [[Madonna (entertainer)|Madonna]] born". It was reported that its main ability over the Knowledge Graph was to gather information automatically rather than relying on crowd sourced facts compiled by humans; by the time of the 2014 report, it had collected over 1.6 billion facts, 271 million of which were considered "confident facts", a term for information deemed more than 90% true.

2014年8月，《新科学家》杂志报道说，谷歌已经启动了知识库。发表后，谷歌联系了 Search Engine Land，解释说知识库是一篇研究论文，不是谷歌的活跃服务，在其报告中，Search Engine Land 引用了该公司的一些迹象，即正在试验“多种模型” ，以检验从文本中自动收集意义的可能性。知识库旨在处理事实，自动收集并整合来自互联网的信息，形成一个能够直接回答诸如“麦当娜出生在哪里”等问题的知识库。据报告，它在知识图谱方面的主要能力是自动收集信息，而不是依靠人为汇编的众包事实; 截至2014年报告时，它已收集了16亿多事实，其中2.71亿被视为”确信事实” ，这个术语指的是被认为超过90% 正确的信息。
== Criticism ==
=== Lack of source attribution ===
By May 2016, knowledge boxes were appearing for "roughly one-third" of the estimated 100 billion monthly searches the company processed. Dario Taraborelli, head of research at the [[Wikimedia Foundation]], told ''[[The Washington Post]]'' that Google's omission of sources in its knowledge boxes "undermines people’s ability to verify information and, ultimately, to develop well-informed opinions". The publication also reported that the boxes are "frequently unattributed", such as a knowledge box on the age of actress [[Betty White]], which is "as unsourced and absolute as if handed down by God".<ref>{{cite web |first=Caitlin |last=Dewey |title=You probably haven’t even noticed Google’s sketchy quest to control the world’s knowledge |url=https://www.washingtonpost.com/news/the-intersect/wp/2016/05/11/you-probably-havent-even-noticed-googles-sketchy-quest-to-control-the-worlds-knowledge/ |website=[[The Washington Post]] |date=May 11, 2016 |accessdate=December 10, 2017}}</ref>

到2016年5月，在该公司每月处理的约1000亿次搜索中，“大约三分之一”的知识盒出现了。维基媒体基金会的研究主管 Dario Taraborelli 告诉《华盛顿邮报》 ，谷歌在其知识库中遗漏信息来源，“损害了人们核实信息的能力，并最终形成消息灵通的观点”。该出版物还报道称，这些盒子“经常不具名” ，比如一个关于女演员贝蒂 · 怀特年龄的知识盒，“来源不明，绝对无误，就像上帝传下来的一样”。
=== Declining Wikipedia article readership ===
According to ''[[The Register]]'', the implementation of direct answers in Google search results has caused significant readership declines for the online encyclopedia [[Wikipedia]], from which the Knowledge Graph obtains some of its information.<ref>{{cite web |first=Andrew |last=Orlowski |title=Google stabs Wikipedia in the front |url=https://www.theregister.co.uk/2014/01/13/google_stabs_wikipedia_in_the_front |website=[[The Register]] |date=January 13, 2014 |accessdate=December 10, 2017}}</ref> ''[[The Daily Dot]]'' noted in 2014 that "Wikipedia still has no real competitor as far as actual content is concerned. All that's up for grabs are traffic stats. And as a nonprofit, traffic numbers don't equate into revenue in the same way they do for a commercial media site". After the article's publication, a spokesperson for the [[Wikimedia Foundation]], which operates Wikipedia, stated that it "welcomes" the Knowledge Graph functionality, that it was "looking into" the traffic drops, and that "We've also not noticed a significant drop in search engine referrals. We also have a continuing dialog with staff from Google working on the Knowledge Panel".<ref>{{cite web |first=Joe |last=Kloc |title=Is Google accidentally killing Wikipedia? |url=https://www.dailydot.com/news/wikipedia-falling-traffic-meaning/ |website=[[The Daily Dot]] |date=January 8, 2014 |accessdate=December 10, 2017}}</ref>

据《登记册》报道，谷歌搜索结果中直接答案的使用导致在线百科全书维基百科的读者人数明显下降，知识图谱从中获取了一些信息。《每日点报》在2014年指出，“就实际内容而言，维基百科仍然没有真正的竞争对手。所有这些都是交通统计数据。而且作为一个非营利组织，流量数字并不像商业媒体网站那样等同于收入。”。这篇文章发表后，运营维基百科的维基媒体基金会发言人表示，他们“欢迎”知识图谱功能，正在“调查”流量下降的情况，并且“我们也没有注意到搜索引擎推荐数量的显著下降。我们还与谷歌知识小组的工作人员不断进行对话”。
