A new profile is available on the Xenky site today. SchemaLogic is a controlled vocabulary management system. The system combines traditional vocabulary management with an organization wide content management system specifically for indexing words and phrases. The analysis provides some insight into how a subsystem can easily boost the cost of a basic search system’s staff and infrastructure.
Taxonomy became a chrome trimmed buzzword almost a decade ago. Indexing has been around a long time, and indexing has a complete body of practices and standards for the practitioner to use when indexing content objects.
Just what an organization needs to make sense of its text, images, videos, and other digital information/data. At a commercial database publsihing company, more than a dozen people can be involved in managing a controlled term list and classification coding scheme. When a term is misapplied, finding a content object can be quite a challenge. If audio or video are misindexed, the content object may require a human to open, review, and close files until the required imnage or video can be located. Indexing is important, but many MBAs do not understand the cost of indexing until a needed content object cannot be found; for example, in a legal discovery process related to a patent matter. A happy quack to http://swissen.in/swictingsys.php for the example of a single segment of a much larger organization centric taxonomy. Consider managing a controlled term list with more than 20,000 terms and a 400 node taxononmy across a Fortune 500 company or for the information stored in your laptop computer.
Even early birds in the search and content processing sector like Fulcrum Technologies and Verity embraced controlled vocabularies. A controlled term list contains forms of words and phrases and often the classification categories into which individual documents can be tagged.
The problem was that lists of words had to be maintained. Clever poobahs and mavens created new words to describe allegedly new concepts. Scientists, engineers, and other tech types whipped up new words and phrases to help explain their insights. And humans, often loosey goosey with language, shifted meanings. For example, when I was in college a half century ago, there was a class in “discussion.” Today that class might be called “collaboration.” Software often struggles with these language realities.
What happens when “old school” search and content processing systems try to index documents?
The systems can “discover” terms and apply them. Vendors with “smart software” use a range of statistical and linguistic techniques to figure out entities, bound phrases, and concepts. Other approaches include sucking in dictionaries and encyclopedias. The combination of a “knowledgebase” like Wikipedia and other methods works reasonably well.

Finally, everything you need to explain database indexing to your mom over breakfast. Stack Overflow hosts the discussion, “How Does Database Indexing Work?” The original question, posed by a user going by Zenph Yan, asks for an answer at a “database agnostic level.” The lead answer, also submitted by Zenph Yan, makes for a respectable article all by itself. (Asked and answered by the same user? Odd, perhaps, but that is actively encouraged at Stack Overflow.)
Yan clearly defines the subject at hand:
“Indexing is a way of sorting a number of records on multiple fields. Creating an index on a field in a table creates another data structure which holds the field value, and pointer to the record it relates to. This index structure is then sorted, allowing Binary Searches to be performed on it.
“The downside to indexing is that these indexes require additional space on the disk, since the indexes are stored together in a table using the MyISAM engine, this file can quickly reach the size limits of the underlying file system if many fields within the same table are indexed.”
Yan’s explanation also describes why indexing is needed, how it works (with examples), and when it is called for. It is worth checking out for those pondering his question. A couple other users contributed links to helpful resources. Der U suggests another Stack Overflow discussion, “What do Clustered and Non Clustered Index Actually Mean?“, while one, dohaivu, recommends the site, Use the Index, Luke.

An SEO expert advocates better indexing in the recent article “Top 5 Arguments For Implementing a Tag Management Solution” on Search Engine Watch. The article shares that because of increased functionality and matured capabilities of such systems, tag management is set for a “blowout year” in 2013.
Citing such reasons as ease of modifying tags and cost reduction, it is easy to see how businesses will begin to adopt these systems if they haven’t already. I found the point on code portability and becoming vendor agnostic most appealing:
“As the analytics industry matures, many of us are faced with sharing information between different systems, which can be a huge challenge with respect to back-end integrations. Tag management effectively bridges the gap between several front-end tagging methodologies that can be used to leverage existing development work and easily port information from one script or beacon to another.”
I think this is a very interesting concept and I love the notion of governance as a way to improve indexing. I am reminded of the original method from the days of the library at Ephesus. Next month, the same author will tackle the most common arguments against implementing a tag management system. We will keep an eye out.

Oracle’s support of locally partitioned indexes has created a need for users to be able to split those indexes and rebuild them in a timely manner. How do you rebuild an index without making your application unavailable for the entire time?
Prsync’s look into the maintenance disadvantages and subsequent problem solving by Oracle in “Partition Maintenance and Oracle Text Indexes” gives us a look at something new; a “Without Validation” and “Split Partition” features. These options offer a way to rebuild indexes without checking each line-by-line first.
“That solves the problem, but it’s rather heavy-handed. So instead we need to institute some kind of “change management”. There are doubtless several ways to achieve this, but I’ve done it by creating triggers which monitor any updates or inserts on the base table, and copy them to a temporary “staging” table. These transactions can then be copied back to the main table after the partition split or merge is complete, and the index sync’d in the normal way.”
So now that there is a solution, but, by avoiding the need for a system to check every partition key value to make sure the row is going to the correct partition, there is need for extra care when using the without validation feature.
It’s a long needed saving grace that will save time and ultimately money by getting apps back up and running in a more efficient manner but there is no substitute for attention to detail. For a more in-depth look at the process we suggest heading over to prsync.

A reader sent me a link to “Manipulating Google Scholar Citations and Google Scholar Metrics: Simple, Easy, and Tempting.” I am not sure how easy and tempting the process of getting a fake scholarly paper into the Google index is, but the information provided is food for thought. Worth a look, particularly if you are a fan of traditional methods for building a corpus and delivering on point results which the researcher can trust. The notion of “ethics” is an interesting additional to a paper which focuses on fake or misleading research.

Zdnet’s recent article focusing on listing, “The 10 Oldest Significant Open Source Programs,” still in popular usage today becomes redundant and neglects to mention other, more relevant projects. Open source software and freeware projects have been influencing software development since the early days of computers.
According to the article:
“Both concepts were actually used long before proprietary software showed up. As Richard M. Stallman, (rms) free software’s founder noted, ‘When I started working at the MIT Artificial Intelligence Lab in 1971, I became part of a software-sharing community that had existed for many years. Sharing of software was not limited to our particular community; it is as old as computers [...]‘”
Linux has certainly had incredible success as the foundation for the internet and the most ported operating system in the world, running on everything from Android devices to super computers. Python has also proven its impact by becoming the fastest growing open source programming language.
While the article goes on to list several other programming languages and another operating system, I cannot help but notice the lack of open source search engine and indexing software. Lucene and Solr have been around since 1999 and 2004, respectively. These projects merged in March 2010, and have just received a robust update. Not only are these programs currently still in use, but they are making strides towards solving the search problems that plague big enterprise.

An impressive showing in second seed round funding–$2.5 million to be exact–was reported by open source file sync and share software company OwnCloud Inc. According to the TechCrunch article titled, “On-Premise Cloud Storage/Sharing Startup, OwnCloud, Closes $2.5M Second Seed Round, Led By General Catalyst Partners,” the round was led by investor General Catalyst Partners as well as new investors.
The Boston-based startup plans to use the money for continued expansion in its enterprise and education customer base as well as support service providers. The article shares:
“‘We’ve been excited about ownCloud since its infancy, and after watching everything they’ve accomplished in a very short time, it validated our belief that they’d developed an exceptional team with an exceptional product,’ said [General Catalyst Managing Director] Bohn in a statement. ‘There’s no one in this increasingly crowded market that can do the things ownCloud does – integrate closely with existing IT, innovate at lightning speed and offer choice of storage locations. With those capabilities already in place differentiating it from the competition, we’re confident that ownCloud will succeed.’”
Serving specific industries and sectors is a great niche for companies concentrating on transformation from storage to deployment. Trusting a solution such as Intrafind, based upon well-formed technology to deploy enterprise solutions that fit the organization, may be a wiser choice in some sectors such as finance and pharmaceuticals.

What is Big Data and what can it do for businesses today? That seems to be the billion dollar question, as businesses literally spent billions on Big Data programs, software and projects this past year. The irony is that despite all the headline hype and the funds being invested, companies are still not sure what they are getting out of Big Data according to Business Insider’s article “Enterprises Are Spending Wildly On ‘Big Data’ But Don’t Know If It’s Worth It Yet”.
This is not to say that corporations do not have Big Data designs in mind for the future:
“Big Data” means scooping up large quantities of information, often from nontraditional, server-busting sources like Web traffic logs or social media, and using it to make business decisions in real time. Including things like watching competitors, monitoring their own brands, creating new services that they can sell, and tracking product and pricing information.”
With over $4.3 billion spent in 2012 and an estimated $34 billion expected in 2013 it is no wonder that Big Data has been generating a lot of buzz. However, all the hype means nothing without an eventual increase in efficiency and ROI. When it comes to finding the right data, companies would benefit from the use of an established search provider like Intrafind that offers rich tagging features and secure search within the enterprise.
