The free-form nature of Graph style data offers a lot of flexibility for connecting data, but that freedom can also make it more challenging to find interesting patterns or simply navigate through your data. It has become typical for RDF data sets to contain thousands of classes and relationship types, making it hard to even formulate the analytics and queries you want to perform.
Gruff, a visual analytics and discovery tool, was developed by Franz to specifically address these Graph data challenges in large data sets. Gruff lets you intelligently explore graphs in multiple views:
The new Gruff v5 uniquely offers users a powerful capability to mark an interesting visual pattern in the Graphical View and convert that automatically into a textual SPARQL or Prolog query. This query code generator operating in conjunction with new zoom in - out controls on Gruff's large graph visualization engine provides users with an unmatched graph discovery tool.
Join us for this webcast training session to learn how to:
Gruff, a free tool, is simple to install and provides an easy on-ramp for non-technical users to engage the Semantic Web. Join us for this one hour training session.

Updating Allegro CL means getting and applying available patches for your version and platform. Patches are posted when they become available. Several tools included with Allegro CL assist in updating the product. Updates are not automatic, although (unless you turn them off) you may get automatic reminders that an update is suggested.
Updating involves two steps: downloading available patches and rebuilding images. Patches cannot always simply be loaded into a Lisp image, since (among other reasons) modified functions might be compiled inline in the existing image (and thus will not be changed) and modified macros will not replace compiled calls. Using in-Lisp tools to download patches therefore requires (at some point) exiting from Lisp and running a separate program. Or you can run a different program (outside Lisp) which both finds and downloads relevant patches and rebuilds images.
Why update? Updating is recommended unless you have a stable application and no time to verify its stability with the new patches (such as a demo to backers this afternoon). Patches can, of course, introduce problems. This can happen in two ways:
One, the patch can contain an error (and so introduce a bug) or can interact badly with your code (by slowing down some heavily used feature). The patch, by correcting code might cause your code to fail because your code depended on the uncorrected behavior (see the full article for an example).
Number two is particularly dicey for us at Franz and we often delay such changes until releases but sometimes consider the change important enough to release the patch anyway. In those cases, the release notes are always updated to note the behavior change.
So, it is very important to test your application after applying patches. If you have difficulty with a patch, note that you can remove it.

The main theme of the 2013 European Lisp Symposium is on the use of these languages with respect to the current grand challenges: big tables, open data, semantic web, network programming, discovery, robustness, runtime failures, etc. The European Lisp Symposium 2013 solicits the submission of papers with these specific themes in mind, alongside the more traditional tracks which have appeared in the past editions.

Graph Search, as recently popularized by Facebook, is also relevant to enterprise information management. Companies are looking to Graph solutions that facilitate understanding of the "connectedness" of their data and as a means to manage the complexity of relationships between elements of information. The Semantic Web has long promised the value of "The Graph" and offers a world of shared information usable beyond the boundaries of legacy applications, inflexible content silos and rigid organizational boundaries. Add in the volume, velocity and variety that is Big Data and we are now hitting stride for semantic technologies to deliver on the promise.
Using real client examples, this webinar demonstrates how organizations use two types of semantic application, namely Content Intelligence and Graph Databases to organize enterprise knowledge. There are many ways to use these technologies but one that is gaining momentum is to semantically classify unstructured documents using ontologies in order to draw new data connections and meaning from very large information sets.
In this talk we will demonstrate two projects where a combination of SKOS/OWL based models, entity extraction, rule based classification, search engines and an RDF Graph Database are used to create a semantic retrieval engine for unstructured documents that delivers new insights to the user.
The business benefits of these projects have included faster development of products; more rapid time to market; improved and more efficient maintenance procedures; new ways of working with information to service customers; enhanced data security and protection; lower cost adherence to compliance tasks.
