Facebook Search Now Recognizes Objects in Photos - Search Engine Journal
Facebook's artificial intelligence (AI) team has built a visual search system that can recognize content that appears in photos and return relevant search results. Called Lumos, Facebook originally created the platform so that its visually impaired users could understand the content of photos. But Facebook recognized that everyone could benefit from this type of visual search system. Facebook's image search system can detect and segment objects, scenes, animals, places, and clothes that appear in images or videos โ and understand them. For instance, let's say you search for "black shirt photo."
ATOL: A Framework for Automated Analysis and Categorization of the Darkweb Ecosystem

We present a framework for automated analysis and categorization of .onion websites in the darkweb to facilitate analyst situational awareness of new content that emerges from this dynamic landscape. Over the last two years, our team has developed a large-scale darkweb crawling infrastructure called OnionCrawler that acquires new onion domains on a daily basis, and crawls and indexes millions of pages from these new and previously known .onion sites. It stores this data into a research repository designed to help better understand Torโs hidden service ecosystem. The analysis component of our framework is called Automated Tool for Onion Labeling (ATOL), which introduces a two-stage thematic labeling strategy: (1) it learns descriptive and discriminative keywords for different categories, and (2) uses these terms to map onion site content to a set of thematic labels. We also present empirical results of ATOL and our ongoing experimentation with it, as we have gained experience applying it to the entirety of our darkweb repository, now over 70 million indexed pages. We find that ATOL can perform site-level thematic label assignment more accurately than keywordbased schemes developed by domain experts โ we expand the analyst-provided keywords using an automatic keyword discovery algorithm, and get 12% gain in accuracy by using a machine learning classification model. We also show how ATOL can discover categories on previously unlabeled onions and discuss applications of ATOL in supporting various analyses and investigations of the darkweb.
Building an end-end search engine
In analytics, we retrieve information from various data sources; it can be structured or unstructured. The biggest challenge here is to retrieve information from unstructured data mainly texts. Here machine learning comes into the picture to overcome this challenge. Different algorithms have been designed in different platforms but here we will discuss one technique that can be applied in python. The process can be explained better by an example.
Zuckerberg charity buys AI search engine to battle disease
A charitable foundation backed by Mark Zuckerberg and his wife said Monday it has bought a Canadian artificial intelligence startup as part of a mission to eradicate disease. The Chan Zuckerberg Initiative did not disclose financial terms of the deal to acquire Toronto-based Meta, which uses AI to quickly read and comprehend scientific papers and then provide insights to researchers. Meta capabilities will be unified in a tool made available for free to scientists. Meta artificial intelligence can analyze insights across millions of papers, finding connections and patterns at scales and speeds impossible for humans to match unassisted. In the field of biomedicine alone, thousands of research papers are published daily.
Chan Zuckerberg Initiative acquires and will free up science search engine Meta
Mark Zuckerberg and Priscilla Chan's $45 billion philanthropy organization is making its first acquisition in order to make it easier for scientists to search, read and tie together more than 26 million science research papers. The Chan Zuckerberg Initiative is acquiring Meta, an AI-powered research search engine startup, and will make its tool free to all in a few months after enhancing the product. Meta could help scientists find the latest papers related to their own projects, while assisting funding organizations to collaborate with researchers and identify high-potential areas for investment or impact. What's special about Meta is that its AI recognizes authors and citations between papers so it can surface the most important research instead of just what has the best SEO. It also provides free full-text access to 18,000 journals and literature sources. Meta co-founder and CEO Sam Molyneux writes that "Going forward, our intent is not to profit from Meta's data and capabilities; instead we aim to ensure they get to those who need them most, across sectors and as quickly as possible, for the benefit of the world."
Chan-Zuckerberg Initiative acquires science-search engine Meta, sets it free
Science search engine Meta has signed an agreement to be acquired by the Chan Zuckerberg Initiative, pending shareholder and court approvals, it announced late Monday. The Facebook-founder-owned philanthropic organization revealed (on Facebook) that it would offer Meta's tools free to all researchers. Meta's secret sauce is artificial intelligence, rather than the more programmatic algorithms used by search engines like Google, and that it's optimized for scientific research. By opening up the tool to all, CZI's goal is to break down some of the barriers that preclude the sharing of information, thereby encouraging scientific progress. "In the field of biomedicine alone, researchers publish more than 4,000 scientific papers every day. But many of these papers will not be read by the scientists who could learn the most from them," said CZI's Cori Bargmann and Brian Pinkerton, in a statement.
Chan Zuckerberg Initiative acquires Meta's scientific search engine
In September, Facebook CEO and his wife Dr. Priscilla Chan promised to spend a whopping $3 billion of the Chan Zuckerberg Initiative's extensive capital over the next 10 years, as it works towards its lofty goal of curing, preventing or managing all diseases by the end of the century. To get a little bit closer to that goal, the Initiative announced Monday that it will acquire the AI-powered research paper search engine Meta and make the service free for anyone to use. Meta's search platform uses machine intelligence to analyze the number and quality of citations in medical journals and research papers, and then sorts them into the largest knowledge graph of its kind. Search results are then ranked in order of importance, similar to how Google News search gives a higher rank to highly linked sources, thus making it easier to find the most relevant or authoritative research among the thousands of scientific papers that are published every day. While that will undoubtedly help students and scientists save tons of time sifting through articles on PubMed, Meta can also help organizations decide where to direct their research budgets by identifying trends in certain areas of study or finding authors who have shown promising work in the past.
Travel brands on alert as Google increases machine learning on search results
Travel brands should ensure they consider the search "intent" of prospective customers when optimising their pages, as Google turns more to advanced tech to serve results. With the search giant's increased use of machine learning and sophisticated artificial intelligences techniques to display results, smaller travel brands in particular must understand how a subtle shift is taking place in how SERPS (Search Engine Results Pages) are served. Larger travel companies, Searchmetrics argues, have an advantage as Google appears to rank them higher for content than similar items from lower-profile brands. Google is looking to understand the "real intention" behind words used by consumers, in a bid to make results more relevant, says Marcus Tober, Searchmetrics CTO and founder. "With the help of user signals, such as how often certain results are clicked and how long people spend there, the search engine gets a sense of how well searchers' questions are answered; allowing it to continually refine and improve relevance. "A searcher who types'things to remember for my beach holiday' into the search box is most likely looking for a short list for example; someone who types'height Mont Blanc' wants a single piece of information, while a query like'nice beach mallorca' is most likely wanting a series of images and a'how to pack a suitcase' query might be best served with video content." Interestingly, word count on content is beginning to become a determininh factor of the placement of sites in search results. This, according to Searchmetrics, is due to top performing results generally more detailed, cover more aspects of a topic (destination, for example). The number of keywords, however, is no longer as important as previously thought of, Tober argues. "Google is no longer just trying to reward pages that use more matching keywords with higher rankings; it is trying to interpret the search intention and boosting the content that is most relevant to the query." Finally, backlinks are also becoming less important to achieve a high ranking in SERPS. It remains a "strong correlation", Tober says, but things have changed, not least because mobile searches are now so popular and, generally, pages are more often than not "shared" or "liked", rather than linked to. "Google's application of machine learning to evaluate search queries and web content means that the factors it uses to determine search rankings are changing all the time.
'Google promotes its own products on its search engine'
Google is using the space above its search results to promote products owned by its parent company, Alphabet, Inc., it was reported on Thursday. The Internet search giant was found to utilize the precious space in order to push various products like its own Pixel phones as well as Nest smart thermostats and smokes detectors, and Android smart watches, The Wall Street Journal reported. Nest Labs is a Palo Alto, California-based company that manufactures thermostats, smoke detectors, and other home security products. It was acquired by Alphabet, Inc. in 2014 for $3.2billion. Google is using the space above its search results to promote products owned by its parent company, Alphabet.
