Carrot Search: Lingo4G: FAQ

What is the cost of a Lingo4G license?

Lingo4G comes in five editions, please get in touch for pricing.

Can I get a trial license?

Absolutely! Please contact us for a free evaluation package.

What are the typical applications of Lingo4G?

The natural use case for Lingo4G is analyzing large volumes of fairly static human-readable text, such as scientific papers, business or legal documents. Lingo4G can give an instant overview of the topics discussed in the whole collection or in the requested subset of it.

Where can I learn more about Lingo4G?

The best place to start would be the Lingo4G Manual. If you'd like to test Lingo4G on your own data, please get in touch.

Can Lingo4G be integrated with C#?

Lingo4G comes with a REST API that you can call from any environment and programing languauge, including C#.

Which languages does Lingo4G support?

Currently, Lingo4G can only process English text. If you'd like to apply Lingo4G to content written in a different language, please contact us.

What are the system requirements for Lingo4G?

Lingo4G can run on any platform supporting Java 1.8 or later. While Lingo4G processing cannot currently be distributed to multiple machines, a high-end workstation with fast SSD storage should be capable of handling collections of several tens of gigabytes. For most data sets not exceeding gigabytes, any computer with 4GB of memory and some disk space will be sufficient. Please see the Requirements section of Lingo4G manual for more details.

How does Lingo4G differ from Lingo3G?

The main difference is that Lingo3G was designed for real-time clustering of small-to-medium collections of documents (up to about 50 MB of text), while Lingo4G can handle much larger collections (up to about 50 GB of text, millions of documents).

Another difference is that Lingo4G needs to index all documents in your collection before it can cluster them, much like a full text search engine needs to index content to make it searchable. Lingo3G, on the other hand, performs ad-hoc processing without the need for initial indexing.

For a more detailed comparison, please see the Lingo4G vs. Lingo3G section in Lingo4G manual.

Will I get Lingo4G as an upgrade from Lingo3G?

No. Lingo3G and Lingo4G are two separate products we intend to offer and maintain independently. Lingo3G will remain an engine for real-time clustering of small and medium collections, while Lingo4G will address clustering of large data sets. Therefore, Lingo4G is not an upgrade to Lingo3G, but a complementary offering.

Having said that, if you would like to switch from Lingo3G to Lingo4G, we will offer a license trade-in option and count the initial Lingo3G license purchase fee towards the Lingo4G license fee. After you trade-in your Lingo3G license, you will not be able to use it any more. Extended Lingo4G evaluation period will serve as a transition grace period.

Easy to integrate, many tuning options, very fast and lightweight.

I’ve shown two board members of our client company what our FoamTree-powered app does. Amazing what a good visualization can accomplish :-)
