Sindice posts

It is with sadness that the Sindice team here at Insight say goodbye to two of the original founders of Sindice.com,  Dr. Giovanni Tummarello and Dr. Renaud Delbru.  Renauld and Giovanni are with the project since it’s inception and have been crucial for Sindice to become a showcase for what is possible using […]

We are happy to announce the availability of SIREn 1.0 under the Apache License Version 2.0. SIREn is the information retrieval engine that has been powering Sindice.com these past years. SIREn has been developed as a plugin for Apache Lucene and Apache Solr to enable efficient indexing and searching of arbitrary structured documents, e.g., JSON […]

How to get some unexpected big data satisfaction. First: build an infrastructure to process millions of document documents. Instead of just doing it home-brew, however, do your big data homework, no shortcuts. Second: unclog some long standing clogged pipe The feeling is that of “it all makes sense” and it happened to us the other […]

SPARQL is really hard to beat as a tool to experiment with data integration across datasets.  For this reason we get many request on what data we have in our sparql.sindice.com, frequency of  updates, etc. We admit there was a bit of disappointment as in the past months we were not able to keep up […]

The original Sig.ma The http://sig.ma service was created as a demonstration of live, on the fly Web of Data mashup. Provide a query and Sig.ma will demonstrate how the Web of Data is likely to contain surprising structured information about it (pages that embed RDF, RDFa, Microdata, Microformats) By using the Sindice search engine Sig.ma allows a […]

Having streamlined several procedures inside Sindice, rebuilding the sindice index from scratch now takes just a few hours. Over the weekend, we built a new Sindice index based on the latest updates of Siren and improvements to the pipelines. This is now in production and sports the following enhancements: Ranking no more big docs first […]

Luckly we’re now getting close to their deployment and today we’re happy to begin by introducing SIREn, the new Sindice core index,  its supporting new frontend and the API.  SIREn: Sindice’s own semantic search engine SIREn (Semantic Information Retrieval […]

This is mainly a test post to verify that the Sindice blog continues to work after migrating it to a new server. But it is also a good opportunity to briefly mention the upgrades we are making to the Sindice infrastructure. I’m happy to report that Sindice has been suffering from some growing pains over […]

So far semantic web search engines and semantic aggregation services have been inserting datasets by hand or have been based on “random walk” like crawls with no data completeness or freshness guarantees. After quite some work, we are happy to announce that Sindice is now supporting effective large scale data acquisition with *efficient syncing* capabilities based on […]

Hi. Due to an expansion of one of our datacentres (and the electrical work that this implies), Sindice and related services such as sig.ma will be down from 1730 GMT+1, 11-Jun (Friday) to 1730 GMT+1, 12-Jun (Saturday). This major upgrade will give us increased room to grow the Sindice infrastructure over time. On 27-May we […]
