We are happy to announce the first release of our Semantic Assistants 
integration for Liferay-based web portals. Portals are web-based 
software applications that can provide a central entry point to a 
multitude of heterogeneous data sources. Liferay (see 
http://www.liferay.com/) is an open source, JSR 286-compliant enterprise 
portal system written in Java. The motivation behind our integration is 
to bring the power of Natural Language Processing (NLP) techniques to 
web portals, with the ultimate goal of enabling portal systems to 
automatically process their embedded textual content. In this way, 
'intelligent' portals can start to offer content analysis services to 
their users, taking into account contextual information beyond their 
roles and permissions.

Our open-source solution is the first custom 'portlet' for Liferay that 
allows any other portlets in the portal to invoke various NLP pipelines 
deployed in the General Architecture for Text Engineering (GATE, see 
http://gate.ac.uk) on their content. These NLP pipelines are brokered to 
the portal as W3C standard web services through our Semantic Assistants 
framework. This integration provides for a multitude of novel 
applications in the context of portal systems, such as named entity 
recognition, automatic summarization, quality assurance, among others.


Features
=====

This first release includes the following features:

o Light-weight Semantic Assistants Liferay Portlet:
NLP capabilities are embedded into a Liferay portal by installing the 
custom 'Semantic Assistants' portlet. Without requiring modifications on 
the portal core, this portlet can exchange textual content and NLP 
results with other arbitrary portlets through rendering parameters in 
the portal system. This portlet also provides a jQuery-based user 
interface, through which users can inquire about and invoke NLP services 
on a portal's content.

o NLP Pipeline Independent Architecture:
The SA-Liferay integration is backed by the Semantic Assistants server, 
which
provides a service-oriented solution for offering NLP capabilities in a 
portal
system. This way, any NLP service available in a given Semantic Assistants
server can be invoked through our integration on a portal's content. 
Likewise, the same NLP pipeline can be consumed by other clients, such 
as the MediaWiki-NLP integration.

o Flexible NLP Result Handling:
Depending on the nature of the natural language analysis techniques 
(e.g., entity recognition, summarization, index generation), NLP 
pipelines can produce different types of results, such as annotations or 
new documents. Our SA-Liferay integration offers flexible format 
handling, based on JSON and XML, which provides for a convenient 
separation of NLP pipelines' results from their visual representation.
