Web 3.0: Have we arrived? - Learn more about Expert System
In 1999, Tim Barners-Lee stated: "I have a dream for the web [in which computers] become capable of analyzing all the data on the web. A "Semantic Web", which should make this possible, has yet to emergeโฆ" Since then, the idea of a semantic web has helped generate and sustain our expectations around the web 3.0. Eighteen years later, I wonder if we have finally realized that dream. Have we crossed the line where computers, and their software, are really capable of analyzing all of the data on the web? And if we haven't completely crossed that line, at least we have a steady foot on it.
HUNT FOR TABERNACLE Experts search for site that held Ark of the Covenant
At the site of an ancient city on the West Bank, archaeologists are hunting for evidence of the tabernacle that once housed the Ark of the Covenant. Associates for Biblical Research, a consortium of individuals and universities, recently completed four weeks of excavation in Shiloh with the goal of eventually locating the tabernacle. Dr. Scott Stripling, director of excavations at Shiloh and provost at The Bible Seminary in Houston, Texas, told Fox News that the site could offer up vital clues. "We have just begun the process of accumulating evidence but we're confident that the tabernacle rested at Shiloh," he said, adding that that the tabernacle was located at Shiloh for about 350 years. "The tabernacle was set up at Shiloh in 1400 B.C. - Joshua 18:1 mentions it."
Algorithm spots dodgy hearts better than an expert doctor
It might not be long before algorithms routinely save lives--as long as doctors are willing to put ever more trust in machines. A team of researchers at Stanford University, led by Andrew Ng, a prominent AI researcher and an adjunct professor there, has shown that a machine-learning model can identify heart arrhythmias from an electrocardiogram (ECG) better than an expert. The automated approach could prove important to everyday medical treatment by making the diagnosis of potentially deadly heartbeat irregularities more reliable. It could also make quality care more readily available in areas where resources are scarce. The work is also just the latest sign of how machine learning seems likely to revolutionize medicine.
Survey on Models and Techniques for Root-Cause Analysis
Solรฉ, Marc, Muntรฉs-Mulero, Victor, Rana, Annie Ibrahim, Estrada, Giovani
Automation and computer intelligence to support complex human decisions becomes essential to manage large and distributed systems in the Cloud and IoT era. Understanding the root cause of an observed symptom in a complex system has been a major problem for decades. As industry dives into the IoT world and the amount of data generated per year grows at an amazing speed, an important question is how to find appropriate mechanisms to determine root causes that can handle huge amounts of data or may provide valuable feedback in real-time. While many survey papers aim at summarizing the landscape of techniques for modelling system behavior and infering the root cause of a problem based in the resulting models, none of those focuses on analyzing how the different techniques in the literature fit growing requirements in terms of performance and scalability. In this survey, we provide a review of root-cause analysis, focusing on these particular aspects. We also provide guidance to choose the best root-cause analysis strategy depending on the requirements of a particular system and application.
WatsonPaths: Scenario-Based Question Answering and Inference over Unstructured Information

J. Watson Research Center)
We present WatsonPaths, a novel system that can answer scenario-based questions. These include medical questions that present a patient summary and ask for the most likely diagnosis or most appropriate treatment. WatsonPaths builds on the IBM Watson question answering system. WatsonPaths breaks down the input scenario into individual pieces of information, asks relevant subquestions of Watson to conclude new information, and represents these results in a graphical model. Probabilistic inference is performed over the graph to conclude the answer. On a set of medical test preparation questions, WatsonPaths shows a significant improvement in accuracy over multiple baselines.
AI Is About Machine Reasoning @CloudExpo @ReneBuest #AI #ML #DX #ArtificialIntelligence
Machine Learning needs tons of data. But what are you going to do when the data only exist in the heads of your employees? However, I guess I provide a good list for your next round of Artificial Intelligence (AI) bullshit bingo. If you've never heard about this term before, just read until the end and you will get its idea and importance for AI. AI Hits Puberty but Gives Enterprises a New Hope In 1955 Prof. John McCarthy already defined AI as the goal to develop machines that behave as though they were intelligent.
Web Application Security: Threats, Countermeasures, and Pitfalls
Penetration testing is a crucial defense against common web application security threats such as SQL injection and cross-site scripting attacks. A proposed web vulnerability scanner automatically generates test data with combinative evasion techniques, significantly expanding test coverage and revealing more vulnerabilities.

Goodstein (1981) has discussed process displays which are compatible with different types of operator skill, using a classification of three levels of behaviour suggested by Rasmussen (1979), i.e. skill based, rule based and knowledge based. The use of different types of skill is partly a function of the operator's experience, though the types probably do not fall on a simple continuum. Chafin (198l) has discussed how interface design recommendations depend on whether the operator is naive, novice/competent, or expert. However, he was concerned with human access to computer data bases when not under time pressure. Man-machine interaction under time pressure raises special problems.
Cool job at Amazon - Applied Scientist
Do you love natural language and believe that getting machines to use it the same way humans do is the most interesting thing one can do? Are you experienced at applying machine learning (ML) to sophisticated natural language processing (NLP) tasks? Are you excited to solve difficult problems in human-computer communication, machine translation, question-answering, knowledge base construction and querying, natural language understanding, natural language generation, search, and multi-modal modeling while applying the latest algorithms and techniques? Are you comfortable operating with large data sets? Do you like finding solutions to problems before others can even articulate what those problems are?
Retrosynthetic reaction prediction using neural sequence-to-sequence models
Liu, Bowen, Ramsundar, Bharath, Kawthekar, Prasad, Shi, Jade, Gomes, Joseph, Nguyen, Quang Luu, Ho, Stephen, Sloane, Jack, Wender, Paul, Pande, Vijay
We describe a fully data driven model that learns to perform a retrosynthetic reaction prediction task, which is treated as a sequence-to-sequence mapping problem. The end-to-end trained model has an encoder-decoder architecture that consists of two recurrent neural networks, which has previously shown great success in solving other sequence-to-sequence prediction tasks such as machine translation. The model is trained on 50,000 experimental reaction examples from the United States patent literature, which span 10 broad reaction types that are commonly used by medicinal chemists. We find that our model performs comparably with a rule-based expert system baseline model, and also overcomes certain limitations associated with rule-based expert systems and with any machine learning approach that contains a rule-based expert system component. Our model provides an important first step towards solving the challenging problem of computational retrosynthetic analysis.
