Neural Networks Finally Have Their Day
May 11, 2015
The Toronto Star offers a thoughtful piece about deep learning titled, “How a Toronto Professor’s Research Revolutionized Artificial Intelligence.” Professor Geoffrey Hinton was instrumental in pursuing the development of neural network-based AI since long before the concept was popular. Lately, though, this “deep learning” approach has taken off, launching many a product, corporate division, and startup. Reporter Kate Allen reveals who we can credit for leading neural networks through the shadows of doubt:
“Ask anyone in machine learning what kept neural network research alive and they will probably mention one or all of these three names: Geoffrey Hinton, fellow Canadian Yoshua Bengio and Yann LeCun, of Facebook and New York University.
“But if you ask these three people what kept neural network research alive, they are likely to cite CIFAR, the Canadian Institute for Advanced Research. The organization creates research programs shaped around ambitious topics. Its funding, drawn from both public and private sources, frees scientists to spend more time tackling those questions, and draws experts from different disciplines together to collaborate.”
Hooray for CIFAR! The detailed article describes what gives deep learning the edge, explains why “machine learning” is a better term than “AI”, and gives several examples of ways deep learning is being used today, including Hinton’s current work at Google and the University of Toronto. Allen also traces the history of the neural network from its conceptualization in 1958 by Frank Rosenblatt, through an era of skepticism, to its recent warm embrace by the AI field. I recommend interested parties check out the full article. We’re reminded:
“In 2006, Hinton and a PhD student, Ruslan Salakhutdinov, published two papers that demonstrated how very large neural networks, once too slow to be effective, could work much more quickly than before. The new nets had more layers of computation: they were ‘deep,’ hence the method’s rebranding as deep learning. And when researchers began throwing huge data sets at them, and combining them with new and powerful graphics processing units originally built for video games, the systems began beating traditional machine learning systems that had been tweaked for decades. Neural nets were back.”
What detailed discussion of machine learning would be complete without a nod to concerns that we develop AI at our peril? Allen takes some time to sketch out both sides of that debate, and summarizes:
“Some in the field believe that artificial intelligence will augment, not replace: algorithms will free us from rote tasks like memorizing reams of legal precedents and allow us to pursue the higher-order thinking our massive brains are capable of. Others think the only tasks machines can’t do better are creative ones.”
I suppose the answers to those debates will present themselves eventually. Personally, I’m more excited than scared by the possibilities. How about you, dear reader?

Elasticsearch Transparent about Failed Jepsen Tests
May 11, 2015
The article on Aphyr titled Call Me Maybe: Elasticsearch 1.5.0 demonstrates the ongoing tendency for Elasticsearch to lose data during network partitions. The author goes through several scenarios and found that users can lose documents if nodes crash, a primary pauses, a network partitions into two intersecting components or into two discrete components. The article explains,
“My recommendations for Elasticsearch users are unchanged: store your data in a database with better safety guarantees, and continuously upsert every document from that database into Elasticsearch. If your search engine is missing a few documents for a day, it’s not a big deal; they’ll be reinserted on the next run and appear in subsequent searches. Not using Elasticsearch as a system of record also insulates you from having to worry about ES downtime during elections.”
The article praises Elasticsearch for their internal approach to documenting the problems, and especially the page they opened in September going into detail on resiliency. The page clarifies the question among users as to what it meant that the ticket closed. The page states pretty clearly that ES failed their Jepsen tests. The article exhorts other vendors to follow a similar regimen of supplying such information to users.

Yahoo and Microsoft Announce Search Partnership Reboot
May 7, 2015
It seems that Microsoft and Yahoo are friends again, at least for the time being. Search Engine Watch announces, “Yahoo and Microsoft Amend Search Agreement.” The two companies have been trying to partner on search for the past six years, but it has not always gone smoothly. Writer Emily Alford tells us what will be different this time around:
“First, Yahoo will have greater freedom to explore other search platforms. In the past, Yahoo was rumored to be seeking a partnership with Google, and under the new terms, Microsoft and Yahoo’s partnership will no longer be exclusive for mobile and desktop. Under the new agreement, Yahoo will continue to serve Bing ads on desktop and mobile, as well as use Bing search results for the majority of its desktop search traffic, though the exact number was undisclosed.
“Microsoft and Yahoo are also making changes to the way that ads are served. Microsoft will now maintain control of the Bing ads salesforce, while Yahoo will take full control of its Gemini ads salesforce, which will leave Bing free to serve its own ads side by side with Yahoo search results.”
Yahoo CEO Marissa Mayer painted a hopeful picture in a prepared statement. She and Microsoft CEO Satya Nadella have been working together, she reports, to revamp the search deal. She is “very excited to explore” the fresh possibilities. Will the happy relationship hold up this time around?

Continued Growth and Success at Syl Semantics
May 5, 2015
The article on Yahoo New Zealand titled Syl Semantics Raises New Capital and Appoints New Directors begins by naming the two freshly-minted non-executive directors, Murray Nash and Gene Turner. This is the result of successful capital raising to the tune of a million dollars for the Wellington-based company. Syl Semantics will continue to focus on growing the company with the assistance of the new directors. The article explains,
“Murray Nash is Managing Director of Zusammen, an advisory firm specialising in strategy, finance and capital markets, risk management, and public policy. In 2013 Murray was manager of the Establishment Unit and subsequently the acting Chief Executive of Callaghan Innovation. Murray has been a senior manager in three financial risk management start-ups in New York – supplying technology solutions to global leaders in banking, insurance, asset management and prudential supervision. He has a MComm (Finance) from the University of Auckland.”
Gene Turner’s background is in law and banking. Syl Semantics was created in 2008 and has grown steadily since then, releasing Syl Search in 2011 with great success. Syl Semantics is focused on what they term “Information Intelligence” or the “ability to access and extract value, meaning and learning from information.” James Fowler, the Director of Sales and Marketing, spoke to the ambition and perseverance of the company, which hopes to gain more of a foothold in New Zealand and Australian markets.

Indexing Rah Rah Rah!
May 4, 2015
Enterprise search is one of the most important features for enterprise content management systems and there is huge industry for designing and selling taxonomies. The key selling features for taxonomies are their diversity, accuracy, and quality. The categories within taxonomies make it easier for people to find their content, but Tech Target’s Search Content Management blog says there is room improvement in the post: “Search-Based Applications Need The Engine Of Taxonomy.”
Taxonomies are used for faceted search, allowing users to expand and limit their search results. Faceted search gives users a selection to change their results, including file type, key words, and more of the ever popular content categories. Users usually don’t access the categories, primarily they are used behind the scenes and aggregated the results appear on the dashboard.
Taxonomies, however, take their information from more than what the user provides:
“We are now able to assemble a holistic view of the customer based on information stored across a number of disparate solutions. Search-based applications can also include information about the customer that was inferred from public content sources that the enterprise does not own, such as news feeds, social media and stock prices.”
Whether you know it or not, taxonomies are vital to enterprise search. Companies that have difficulty finding their content need to consider creating a taxonomy plan or invest in purchasing category lists from a proven company.

EnterpriseJungle Launches SAP-Based Enterprise Search System
May 4, 2015
A new enterprise search system startup is leveraging the SAP HANA Cloud Platform, we learn from “EnterpriseJungle Tames Enterprise Search” at SAP’s News Center. The company states that their goal is to make collaboration easier and more effective with a feature they’re calling “deep people search.” Writer Susn Galer cites EnterpriseJungle Principal James Sinclair when she tells us:
“Using advanced algorithms to analyze data from internal and external sources, including SAP Jam, SuccessFactors, wikis, and LinkedIn, the applications help companies understand the make-up of its workforce and connect people quickly….
“Who Can Help Me is a pre-populated search tool allowing employees to find internal experts by skills, location, project requirements and other criteria which companies can also configure, if needed. The Enterprise Q&A tool lets employees enter any text into the search bar, and find experts internally or outside company walls. Most companies use the prepackaged EnterpriseJungle solutions as is for Human Resources (HR), recruitment, sales and other departments. However, Sinclair said companies can easily modify search queries to meet any organization’s unique needs.”
EnterpriseJungle users manage their company’s data through SAP’s Lumira dashboard. Galer shares Sinclair’s example of one company in Germany, which used EnterpriseJungle to match employees to appropriate new positions when it made a whopping 3,000 jobs obsolete. Though the software is now designed primarily for HR and data-management departments, Sinclair hopes the collaboration tool will permeate the entire enterprise.

Ignoring Search Updates are a Security Risk
April 23, 2015
Searching is an essential function for basic Internet use and it is a vital function in enterprise systems. While searching on the Internet with a search engine might not seem like a security risk, the comparable action on enterprise search could be potentially dangerous. Security Enterprises points out the potential security risks in the article, “SearchBlox Vulnerabilities Underscore Importance Of Updating Enterprise Search Tools.”
Recently the Carnegie Mellon Software Engineering Institute CERT Division compiled a list of all the security risks from SearchBlox’s software. They included ways for hackers to view private information, upload files, cross-site (XSS) scripting, and cross-site request forgeries. Enterprise security developers can learn from SearchBlox’s vulnerabilities by being aware and repairing them before a hacker discovers the information leak.
The problem, however, might come from within an organization rather than out:
“Of all the possible threats, the ability for cybercriminals to conduct XSS attacks from within the product’s default search box is likely the most concerning, Threatpost reported. On the other hand, anyone trying to take advantage of such SearchBlox vulnerabilities would need to be an authenticated user, though there is no shortage of stories about insider threats within the enterprise.”
The article alludes that SearchBlox’s vulnerabilities came from day-to-day activities that keep an organization running. Using SearchBlox as an example, other organizations with enterprise systems will be able to learn where their own products need patches so the same issues don’t happen with them. So what do you take away: most hackers are probably insiders and look for holes in the ordinary, everyday routines.

The Enterprise is a Jungle Search
April 16, 2015
The word collaboration has become one of those corporate power words like “synergy” and “KISS method.” Many people groan inwardly at new ways to “collaborate,” because it usually means another tool they have to learn and will fall out of use in under a year. With the myriad of ways to collaborate digitally, getting any actual collaborating done is difficult. The SAP News blog says enterprise collaboration might be getting a little easier in the article, “EnterpriseJungle Tames Enterprise Search.”
EnterpriseJungle created an application with the SAP Hana Cloud Platform to help companies connect quickly find and connect with experts within or outside their company. The Principal at EnterpriseJungle states that a company’s people search is vital tool to locate and harness information.
“ ‘Large companies are desperate to get a handle on understanding and accessing the expertise available to them at any given moment,’ said Sinclair. ‘Our solutions help companies solve fundamental questions like how do we find the people who are fantastic at what they do, but only known to their closest core group of co-workers? And, how do we easily bring their knowledge and expertise to the front line with minimal extra work? If we can help get information to employees that need it, we’re fundamentally making their lives easier, and making the company’s life easier.’ “
After a description of how EnterpriseJungle’s works and its usefulness for companies, it makes a claim to offer Google-like search results. While it might be a people search tool, the application is capable of much more. It can help people locate experts, track down skill sets, and even improve IT relations.
EnterpriseJungle is hitting on a vital tool for companies. People search has a severe need for improvement and this might be the start of a new enterprise niche market.

SharePoint Gets Serious with Information Governance
March 19, 2015
SharePoint has enjoyed continued success over the last 15 years, but it has not been without some bumps along the way. Information governance is one of the noted areas in which Share has fallen flat. Read more in the CMS Wire article, “Keeping SharePoint In Check with Information Governance.”
The article begins:
“Historically, SharePoint was thought to cause as many information governance problems as it solved. The 2001 to 2003 versions did not show Microsoft putting much effort into helping customers with information governance. But after the massive take up of SharePoint Portal Server 2007 licenses, and the often negative conversations coming out of the sizable SharePoint user community, Microsoft started to take governance issues seriously.”
In addition to keep an eye on your news feed for the latest SharePoint buzz, staying tuned to experts in the field is a great way to save time and get pointed information pertaining to improving a SharePoint installation. Stephen E. Arnold has one such SharePoint feed on his Web site, ArnoldIT.com. Focusing on tips, tricks, and news, Arnold collocates much of content that users and managers alike will find helpful for navigating day-to-day SharePoint operations.
