Webinar: Semantic Web for Developers

GotoWebinar, March 20: Semantic Web for Developers – building semantic applications with PoolParty

This webinar gives insights into software development based on semantic web standards. We will give a short overview over frequently used standards (SPARQL, SKOS and RDF), application scenarios and technologies (OpenRDF, Virtuoso, Solr/Lucene) and we will give live-demos on how to make use of PoolParty technologies to build a variety of semantic applications.

Part 1 (15min):
Short introduction to semantic web and linked data standards, overview over typical application scenarios

Part 2 (30min):
PoolParty architecture, components and APIs: making use of the linked data front end, Sparql endpoint, PoolParty reports, thesaurus API (PPT API), extractor API (PPX API) and semantic search API (PPS API) -  for each API, an example will be shown (incl. returned formats and how to make use of it in a programming language like PHP)

Part 3 (10min):
Putting the pieces together: Combine the APIs to build

- a semantic search engine
- a content recommender
- a linked data mashup

Part 4 (min. 5min):
Questions and answering

SKOS without SPARQL

Today PoolParty Team has announced the first official release of the PoolParty SKOS API.

This API can be installed in addition to a PoolParty Thesaurus Server 3.2 and offers an easy way to programmatically access data of a SKOS thesaurus via RESTful services. The SKOS API can be used without any knowledge about SPARQL .

This first release of the API offers web services to access thesaurus projects, concept schemes, concepts and SPARQL lists. In addition to basic SKOS querying, the API also supports the import of RDF data, SPARQL update and a service to push candidate terms into a thesaurus project triggered by any kind of application (like a CMS or a wiki).

PoolParty PowerTagging – bringing semantics to enterprises

PoolParty PowerTagging (PPP) is on its way: By extending Confluence´s label management, new application scenarios which make use of content recommendation and semantic indexing will be supported soon. PPP will be published at this year´s Atlassian Summit and at SemTechBiz in San Francisco at the beginning of June.

The Problem: weak semantics

Tagging is still not a very popular task, especially in corporate environments. Many users don´t see the benefit of creating metadata to describe the actual content. A typical counter-argument to social tagging is that there are too many words for the same thing. “Even if I am tagging very hard my colleagues won´t find necessarily my pages  because they will use different words to search for the content. I don´t have enough time to insert ‘New York City’, ‘NYC’, ‘Big Apple’ etc. as labels”.

The result: Tagging facilities of enterprise software platforms like Confluence are rarely used and don´t help to index content at all. Search is mostly based on classical full-text indexing. Semantic search as seen more and more on the WWW has still not entered the enterprise realm.

The Solution: thesaurus based indexing

W3C´s Semantic Web technology stack provides means to define controlled vocabularies like thesauri which results into more and more tools and data which make use of standards like SKOS. Tagging based on thesauri means that concepts are attached to pages & documents rather than putting labels on them. Labels like ‘New York City’, ‘NYC’ and ‘Big Apple’ refer to the same concept, thus it should be sufficient if one of the various terms is used for labeling, all the other names of this certain concept should be attached automatically.

PoolParty PowerTagging is able to analyse each Confluence page and to insert concepts from a thesaurus and all of their names automatically. Users can curate all suggested tags or they can also index their spaces automically resulting in a semantic index which makes search more comfortable than ever before.

Usage: enhanced collaboration with enterprise knowledge models

There are two main application scenarios which can be realised on top of Confluence and its PowerTagging extension:

  • Semantic Search: Fully integrated with Confluence´s built-in Lucene based search facility, users no longer have to type in search phrases literally: Even if only ‘New York City’ is mentioned on a page on a word-by-word basis, it´s sufficient to search for ‘Big Apple’ or ‘NYC’ and results will be generated. This feature is especially interesting for domains in which a lot of technical terms or abbreviations are commonly used or for enterprises in multi-lingual environments.
  • Content recommendation: Identifying similar and semantically matching contents especially in larger Confluence instances is a crucial task: Imagine you´re working for a recruiting company and you would like to match a new open position with all people in your applicant database. Or: Imagine you´re working on technical documentation and you can provide your customers automatically with further readings. Or: Imagine you´re working on a slidedeck and you´ll see instantly if some of your colleagues have worked on similar issues recently.

Don´t re-invent the wheel again and again. Save time and money. PPP will help to fulfill these tasks when creating rich contents more efficiently than ever before. You can link similar contents within Confluence automatically and you can fetch further readings even from the WWW like from Wikipedia.

If you are interested in trying out PowerTagging, please drop us a note and we will be happy to support you!

KiWi Software Package Released – Call for KiWi Snow Camp

The 14th of October 2010 was a very special date for the KiWi project: After more than two and a half years of development version 1.0 of the semantic collaborative knowledge management software was published. To celebrate that, the project organized a release party in the planetarium in Vienna, Austria. It was a fine evening that featured speeches of Ross Gardler (Vice President Community, Apache Software Foundation) and David Ayers (Free Software Foundation Europe), followed by a demonstration of KiWi by Sebastian Schaffert (KiWi Project Lead).

KiWi, the Open Source development platform for building Semantic Social Media Applications, offers features required for Social Media applications such as versioning, (semantic) tagging, rich text editing, easy linking, rating and commenting, as well as advanced “smart” services such as recommendations, rule-based reasoning, information extraction, intelligent search and querying, a sophisticated social reputation system, vocabulary management, and rich visualisation.

To make sure, that KiWi does not die, after the closure of the EC-funded periode, the project makes effort to form a community. The release party was thus also an opportunity to get in touch with the project team. Another opportunity to get in touch with the Software and it’s developers behind is in February next year. When KiWi Snow Camp will gonna be somewhere in the Salzburg mountains.

The KiWi projects sponsors ticktes to participate in the camp for all those

  • which have a good idea on how semantic technologies can make social media hit the target?
  • and are inspired by the possibilities of the KiWi platform?

Together with the KiWi Team participants will meet in February 2011 in Salzburg’s mountains to develop ideas, programm, discuss and develop amazing new pieces of code – and of course enjoy the skiing experience. Not to mention receive the glory of recognition from others in the open source communities and within the broader semantic web community.

How to get my trip to the KiWi Snow Camp?

You will need to register as a participant for the KiWi Developer Challenge. Please email kiwimail@kiwi-community.eu to register your intention to participate in the Challenge; if you are not already registered on KiWi Community site, please do so and include a brief biography.
