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.
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.
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.
