There has been a significant growth in the volume and variety of data because of the accumulation of unstructured text data. Companies are now relying on technologies like text analytics and Natural Language Processing (NLP) for making sense of such massively collected data. Text analytics and NLP hold the key to unlocking the business value within these huge data sets. NLP is concerned with making natural language accessible to machines, while text analytics refers to the extraction of useful information from text sources. Today, text analytics and NLP are gradually transforming into a field extremely useful for various business applications, such as competitive analysis, and improving the quality of machine intelligence systems.

Facebook has got big plans for a new $750 million data center in Huntsville, Alabama. On Thursday, the social networking giant announced it was building a new 970,000 square foot facility in Huntsville, a city in the northern part of the US state. "As a growing tech hub, Huntsville seemed like a natural fit for Facebook," the company wrote on a new Facebook post dedicated to the planned data center. "It also provides reliable access to renewable energy, strong local infrastructure, a great set of community partners, and very importantly, an outstanding pool of talent." A Facebook spokesperson confirmed to Business Insider that it is investing $750 million in the project.

After a New York Times reporter published a bombshell story on how Facebook intentionally shared personal information of its users with over 60 different device makers – including the two largest, Apple and Samsung – in order to create "Facebook-like experiences" on those devices, U.S lawmakers and regulators are asking Facebook for answers. What they see is a clear pattern of abuse, in which Facebook pledges over and over again that it has figured out its data sharing problem, but new revelations continually come to light. In its defense, Facebook says that the data sharing partnerships with mobile device manufacturers were only intended to make it easier for these global device makers to build software incorporating Facebook functionality into their smartphone devices. According to Ime Archibong, Facebook Vice President of Product Partnerships, the data-sharing program was controlled and monitored by Facebook from the very beginning, and all integrations with the device manufacturers were personally approved by Facebook. Moreover, while personal user data might have been shared with these device makers, Facebook says it was only used in order to give users access to Facebook messages and notifications on their mobile phones. But the New York Times report suggests that the data-sharing program went far beyond this.

In order to feed this data into our RNN, all input documents must have the same length. We will limit the maximum review length to max_words by truncating longer reviews and padding shorter reviews with a null value (0). We can accomplish this using the pad_sequences() function in Keras. For now, set max_words to 500. We start building our model architecture in the code cell below.

WASHINGTON – A U.S. senator on Thursday is seeking responses from Google parent Alphabet Inc. and Twitter Inc. on whether the U.S. companies have any data-sharing agreements with Chinese vendors, following a disclosure from Facebook Inc. this week. Sen. Mark Warner, a Democrat who is vice chairman of the Intelligence Committee, said in a statement he has written letters to the companies for information on data-sharing agreements, noting that since 2012 "the relationship between the Chinese Communist Party and equipment makers like Huawei and ZTE has been an area of national security concern." Alphabet has said previously it has strategic partnerships with Chinese mobile device manufacturers, including Huawei Technologies Co. Ltd., and Xiaomi, as well as with Chinese technology platform Tencent. It wasn't clear if Twitter has a partnership with any Chinese vendors. Alphabet and Twitter did not immediately respond to questions for comment.

The New York Times recently revealed that Facebook entered into agreements with at least 60 mobile device companies, giving them access to Facebook user data so that the companies could recreate Facebook-like features. Among those companies are four Chinese firms -- Huawei, Lenovo, Oppo and TCL -- which has spurred some concern among US lawmakers. Today, Senator Mark Warner (D-VA) sent letters to both Alphabet and Twitter, inquiring as to whether they entered into similar data-sharing agreements with any mobile device companies based in China. "Since at least October 2012, when the House Permanent Select Committee on Intelligence released its widely-publicized report, the relationship between the Chinese Communist Party and equipment makers like Huawei and ZTE has been an area of national security concern," wrote Warner. He then goes on to ask both companies if they've had agreements in place similar to Facebook's and if so, whether any Chinese firms like Huawei, ZTE, Lenovo or Xiaomi were included.

LONDON – The former head of Cambridge Analytica admitted on Wednesday his firm had received data from the researcher at the center of a scandal over Facebook users' personal details, contradicting previous testimony to lawmakers. Cambridge Analytica, which was hired by Donald Trump in 2016, has denied its work on the U.S. president's successful election campaign made use of data allegedly improperly harvested from around 87 million Facebook users. Former chief Alexander Nix, in earlier testimony to Parliament's media committee, also denied the political consultancy had ever been given data by Aleksandr Kogan, the researcher linked to the scandal. On Wednesday he said it had received data from Kogan. "Of course, the answer to this question should have been'yes,' " Nix said, adding that he thought he was being asked if Cambridge Analytica still held data from the researcher.

Sentiment classification involves quantifying the affective reaction of a human to a document, media item or an event. Although researchers have investigated several methods to reliably infer sentiment from lexical, speech and body language cues, training a model with a small set of labeled datasets is still a challenge. For instance, in expanding sentiment analysis to new languages and cultures, it may not always be possible to obtain comprehensive labeled datasets. In this paper, we investigate the application of semi-supervised and transfer learning methods to improve performances on low resource sentiment classification tasks. We experiment with extracting dense feature representations, pre-training and manifold regularization in enhancing the performance of sentiment classification systems. Our goal is a coherent implementation of these methods and we evaluate the gains achieved by these methods in matched setting involving training and testing on a single corpus setting as well as two cross corpora settings. In both the cases, our experiments demonstrate that the proposed methods can significantly enhance the model performance against a purely supervised approach, particularly in cases involving a handful of training data.

Facebook's data-sharing deals with device-makers included China's Huawei -- a company viewed with suspicion by U.S. intelligence agencies. Here, an ad for the Huawei P20 smartphone is seen in China last month. Facebook's data-sharing deals with device-makers included China's Huawei -- a company viewed with suspicion by U.S. intelligence agencies. Here, an ad for the Huawei P20 smartphone is seen in China last month. Facebook's longstanding agreements that led it to share users' data with device-makers included Chinese phone-maker Huawei – a company of which the U.S. government has long been suspicious, and which intelligence officials view as a security threat.
