TripAdvisor has defended itself against accusations of misleading travelers by failing to stop some of its highest ranked hotels winning their status with fake reviews.UK consumer group Which? Travel analyzed a total of almost 250,000 reviews for the 10 top-ranked hotels in 10 global tourist destinations, from Las Vegas to Cape Town. It found that one in seven of the hotels had "blatant hallmarks" of fake reviews, with others raising "serious concerns."But TripAdvisor called the analysis "flawed" and said its more sophisticated detection tools were able to weed out fraudulent feedback.Which? Travel said that when it reported 15 of the worst cases to TripAdvisor, the reviews giant -- now one of the world's biggest travel websites -- admitted that all but one of the hotels in question had been caught using fake reviews in the past year.Six had previously been penalized, and two had received a "red badge warning" -- where TripAdvisor warns users that the hotel is suspected of using fake reviews, and has "repeatedly failed to remedy its behavior and refuses to cooperate with TripAdvisor's investigators."Yet, Which? Travel said it found that the review patterns had continued unabated despite the measures, and the red badges had been removed.The group has accused TripAdvisor of a "lack of serious ongoing action to address repeated abuse of the system."It says that five-star reviews left by new users who have written no other reviews should be a red flag. Its analysis compared the proportion of first-time five-star reviews with that of first-time three-star reviews, which are less likely to be faked.In total, it studied 247,277 reviews."TripAdvisor's failure to stop fake reviews and take strong action against hotels that abuse the system risks misleading millions of travelers and potentially ruining their holidays," said Which? Travel's Naomi Leach.TripAdvisor has removed hundreds of reviews in light of the investigation, Which? Travel claimed."Striking" evidence of fake reviewsHotels in the Middle East had "striking" amounts of fake positive reviews, according to the research. TripAdvisor docked 730 five-star reviews of the "best" hotel in Jordan following the analysis -- but the hotel has not been given a red badge. It remains in the top 10 in the country.At the top-ranking hotel in Cairo, 79% of five-star reviews came from one-time contributors. Just 14% of three-star reviews came from similar accounts.The hotel has lost its status as a result of the reviews' deletion.Las Vegas was another hotspot for fake reviews. At two of the top-rated hotels, almost half the five-star reviews came from one-time contributors. For a competitor which did not arouse suspicion, the figure was just 3%.Some of the top-ranked hotels in London, Paris, Barcelona and Cape Town "gave reason for suspicion," the research showed, but failed to demonstrate the same patterns across the board.Repeat offendersTripAdvisor called the analysis "based on a flawed understanding of fake review patterns," adding that "it is simply far too simplistic to assume all first-time reviewers are suspicious."It said that Which? Travel did not have access to IP [internet protocol] information or location data, both of which TripAdvisor uses to detect fake reviews."We analyze hundreds of data points about each review -- most of which only we have access to -- and we combine that data with a wealth of knowledge and understanding of review patterns that our team of experts has gained from tracking hundreds of millions of reviews over a near 20-year period," said the company."This includes an ability to track and analyze first-time reviews in far more detail and with far more rigor than Which's team was able to do."Online reviews influence an annual estimated ￡23 billion ( billion) of booking transactions in the UK alone, according to the UK government."Sites like TripAdvisor must do more to ensure the information on their platforms is reliable," said Naomi Leach."If they continue to fall short, they should be compelled to make changes so holidaymakers are no longer at risk of being duped by a flood of fake reviews." 4152

The US military has flown an increased number of reconnaissance flights in international airspace off the coast of Venezuela during the last several days to gather classified intelligence about the embattled government of President Nicholas Maduro, according to two US defense officials.The officials would not detail which US military aircraft are being used, but the Navy and Air Force maintain several large fixed-wing aircraft capable of intercepting communications and monitoring the status of weaponry.The officials noted that the effort is limited to whatever the aircraft can gather by staying in international airspace.Several US military officials continue to emphasize there are no military options actively being considered for the Venezuela crisis. For now, the US military would only contemplate a response if US assets, personnel or the embassy were attacked.Venezuela is in crisis as self-proclaimed interim president Juan Guaido battles Maduro for control.Guaido has called for other nations to send aid to the country in response to worsening food and medicine shortages. Maduro denies a humanitarian crisis exists in Venezuela and says the aid efforts are part of a coup attempt.Over the weekend, violence broke out when the Venezuelan military blocked aid convoys at the country's border.In the state of Tachira, along the border with Colombia, more than 300 people were hurt in clashes that involved firearms and Molotov cocktails, said the Venezuelan government's special envoy for Tachira state, Freddy Bernal.He said the attacks were conducted by irregular groups protesting Maduro's government on the international bridges along the border between Venezuela and Colombia -- the Simon Bolivar bridge in San Antonio and the Francisco de Paula Santander bridge in Ure?a."We registered no deaths despite the violent attacks for more than 15 hours of battle" by groups on the international bridges fighting "against thousands of patriots who fought and defended themselves," he said. CNN has not independently verified the numbers of the injured in these clashes.The opposition group said five people were killed. CNN has not verified those numbers.In other developments:?
