Semantic Web Rule Language (SWRL) combines OWL (Web Ontology Language) ontologies with Horn Logic rules of the Rule Markup Language (RuleML) family. Being supported by ontology editors, rule engines and ontology reasoners, it has become a very popular choice for developing rule-based applications on top of ontologies. However, SWRL is probably not go-ing to become a WWW Consortium standard, prohibiting industrial acceptance. On the other hand, SPIN (SPARQL Inferencing Notation) has become a de-facto industry standard to rep-resent SPARQL rules and constraints on Semantic Web models, building on the widespread acceptance of SPARQL (SPARQL Protocol and RDF Query Language). In this paper, we ar-gue that the life of existing SWRL rule-based ontology applications can be prolonged by con-verting them to SPIN. To this end, we have developed the SWRL2SPIN tool in Prolog that transforms SWRL rules into SPIN rules, considering the object-orientation of SPIN, i.e. linking rules to the appropriate ontology classes and optimizing them, as derived by analysing the rule conditions.

Businesses will be ready for Web 3.0 and web 4.0 evolution which is connecting all devices in the real and virtual world in real-time.This will be more prominent in 2019. By 2020 we will be witnessed to the web 4.0 aka smart web when SEO will be less time consuming and easy.

The first time many of us heard about China's use of facial recognition on jaywalkers was just this week when a prominent Chinese businesswoman was publicly "named and shamed" for improper street crossing. Turns out, she wasn't even there: China's terrifyingly over-the-top use of tech for citizen surveillance made a mistake. The AI system identified Dong Mingzhu's face from a bus advertisement for her company's products. "[The] president of China's biggest air conditioning maker," wrote The Telegraph, "had her image flashed up on a public display screen in the city of Ningbo, near Shanghai, with a caption saying she had illegally crossed the street on a red light." Shortly after, Ningbo traffic police admitted the mistake and claimed to have "completely upgraded the system to reduce the false recognition rate."

The explosive growth in fake news and its erosion to democracy, justice, and public trust has increased the demand for fake news analysis, detection and intervention. This survey comprehensively and systematically reviews fake news research. The survey identifies and specifies fundamental theories across various disciplines, e.g., psychology and social science, to facilitate and enhance the interdisciplinary research of fake news. Current fake news research is reviewed, summarized and evaluated. These studies focus on fake news from four perspective: (1) the false knowledge it carries, (2) its writing style, (3) its propagation patterns, and (4) the credibility of its creators and spreaders. We characterize each perspective with various analyzable and utilizable information provided by news and its spreaders, various strategies and frameworks that are adaptable, and techniques that are applicable. By reviewing the characteristics of fake news and open issues in fake news studies, we highlight some potential research tasks at the end of this survey.

Google has been attacked over reported plans to launch a "censored" search engine in China. Amnest International has launched a petition against the plans, arguing that the apparently launch should be cancelled. Human rights campaigners claim developing a specifically censored search engine would be in conflict with the company's values and that it will limit freedom of expression. They also point out that Google's own staff appear to disagree with the plans. There are a lot of Easter Eggs hidden in Chrome, and more and more are discovered each year.

Dozens of Google employees are speaking out against the company's plan to build a special search engine for China. The employees have joined with Amnesty International, urging Google to cancel the project. The company's plan calls for a search engine that would comply with China's policy of online censorship, often known as the Great Firewall. JASMINE GARSD, BYLINE: The Chinese blogger known as Super Vulgar Butcher used to post about the government's abuses of power. His blog became quite popular.

Amnesty International are holding protests across the globe today calling for an end to Googles plan of censoring their search engine in China. Demonstrations will take place outside Googles HQ's in the United States, the United Kingdom, Australia,Canada, Germany, Hong Kong, The Netherlands and Spain. It was revealed that Google secretly built the censored search engine, code-named Dragonfly, to blacklist certain words such as'human rights' and'student protest'. Amnesty have launched a petition to stop works on the'dystopian' platform which are said to launch in China between January and April 2019. The human rights group say that the move would'set a dangerous precedent for tech companies enabling rights abuses by governments.'

SAN FRANCISCO – Eleven employees comprising engineers and managers at Alphabet Inc.'s Google published an open letter on Tuesday, demanding that the company end development of a censored search engine for Chinese users, escalating earlier protests over the secretive project. Google has described the search app, known as Project Dragonfly, as an experiment not close to launching. But as details of it have leaked since August, current and former employees, human rights activists and U.S. lawmakers have criticized Google for not taking a harder line against the Chinese government's policy that politically sensitive results be blocked. Human rights group Amnesty International also launched a public petition on Tuesday calling on Google to cancel Dragonfly. The organization said it would encourage Google workers to sign the petition by targeting them on LinkedIn and protesting outside Google offices.

Hundreds of Google employees have signed an open letter published Tuesday on Medium demanding that the company cease work on Project Dragonfly, which is aimed at creating a search engine that the Chinese government would be able to control to censor certain results and surveil users. "International human rights organizations and investigative reporters have also sounded the alarm, emphasizing serious human rights concerns and repeatedly calling on Google to cancel the project," the letter reads in part. "So far, our leadership's response has been unsatisfactory." Google has kept much of Project Dragonfly under wraps, but news outlets like the Intercept have obtained documents revealing some of the details. The search engine reportedly would block websites having to do with democracy and political dissidents and also blacklist terms like "human rights." One of the prototypes also reportedly has the capability to link searches to users' phone numbers.

More than 90 Google employees have joined a petition protesting the company's plans to build a search engine that complies with China's online censorship regime. An employee-led backlash against the project has been churning for months at the company, but Tuesday's petition marks the first time workers at Google have used their names in a public document objecting to the plans. The existence of the project, code-named Dragonfly, was confirmed by chief executive Sundar Pichai last month. While China has long blocked search queries for what it has deemed politically sensitive material, Pichai said Google could still help Chinese Internet users find other information, such as health treatments, or steer them away from scams. But the project has drawn critics, who question Google's corporate values and have raised concerns about the consequences of tech companies cooperating with authoritarian governments.
