Globalization (G11n) of an application involves more than just translating text. Internationalization (I18n) is the process of enabling your application to be used in different languages and culture. Localization (L10n) covers the work to provide the application in one specific language and culture. Selected locales can help in providing translated text, but some information needs to be converted (times, dates, currencies).
#NLP #MachineLearning #algorithm learns to tell #stories by summarizing #commercial #RealEstate #data, #earning #profits and spurring #CustomerRetention. #BINGO!
When localizing an application, treat the capabilities as features. Consider the specific use cases and work with the users to refine the approach. There may be design and layout adjustments needed per language. If the application is a CMS, content as well as application resources may need translations.

In this post, we're going to dive into the client-side single-page application, commonly abbreviated as “SPA”. What is considered an SPA? What are important choices to be made when building one? How do you deploy it? When is an SPA a good choice or a bad choice?
In this blog post, I'll discuss the process of building a micro service that is backed by a graph database and the technologies leveraged to accomplish it. I'll be building this microservice in Java using Maven for its declarative dependency management and build process and Dropwizard for its straightforward architecture and configuration, and then connect everything up to an Apache Tinkerpop enabled Graph Database.
Trying to modernize monolithic legacy applications is hard: these applications are core drivers of the business and the risk of messing them up is too great. However, as time goes on, the cost of maintaining these monoliths grows.
We get asked that question a lot given our early customer work with Titan evaluations, participation in the JanusGraph project and usage of Apache TinkerPop while concurrently being a premier DataStax Graph partner.

One of the major hesitations from product stakeholders regarding end-user engagement, specifically user testing, is that they often don’t want anyone to see it till it’s “perfect” or “ready” or “MVP.”
A supernode is a vertex with a large number of edges. In graph theory, these high-degree vertices are known as hubs.
When designing and developing software, it is critical to take into account the limitations of the technology employed, especially hardware—things like computers, boxes and other physical devices. But there’s another aspect to hardware that should be taken into account and is often overlooked: the user.

How do you handle customer #2? You delivered an MVP of some hosted software for customer #1. Your brother-in-law knows a guy who has a similar problem and after a lunch meeting, now you need to add customer #2 to your incubating SaaS tool. Of course customer #1 and customer #2 shouldn’t be able to see each other’s data, but you don’t necessarily want to install and configure everything all over again just because you added another customer.

A case study at Graph Day recounting a client study we did to see whether their database could be reorganized to offer improved query performance. We looked at graph databases (OrientDB, Titan, Neo4J) because they thought of their data as graph data, and relational (Postgresql) because that’s what their database already implemented.

For our presentation at Graph Day, we’ll be walking through one in particular, but really there are a variety of answers you may want.
Everyone gets delusions of grandeur!” That’s what Han Solo said after being frozen in carbonite. I’ve been solving data problems for customers the last year and a half and am now getting back in graph DBMSs. We took a nice look at Titan last week, can’t wait to play with that some more. I’m going to give a bit of the same to Neo4j. All of this as prep for my talk at GraphDay 2016 in Austin, TX.

Business users want to access their software applications from a myriad of devices, all behaving correctly regardless of form factor.
As part of the work we’re doing to refresh our graph database evaluation for a couple of clients (and our upcoming talk at Graph Day!) we took Titan 1.0out for a spin last week. We’ll be doing more in-depth explorations on some in-house and public datasets over the next few weeks, but here’s some preliminary impressions based on a contrast with the Titan we came to know a year ago or so.
“Can’t we just…” I know the phrase. I can’t specify the last instance I heard it. And, worst of all, I’ve said it myself. If I close my eyes, I can see the meeting rooms I’ve heard it in…which is every meeting I’ve ever been in.
What do my users want to do with Big Data? How do they want to visualize it, interact with it and manage it? How big is my data, really? How much data can a human deal with at one time, and how much data should we process at one time? How can the UX accommodate data sources that respond at different rates?
