Since large-scale data sources are usually comprised of a very large schema and billions of instances, keyword search over such datasets offers several challenges mainly related to scalability, interpretation of the keyword query intended meaning. Whereas state-of-the-art keyword search techniques work well for small or medium-sized databases in a particular domain, many of them fail to scale on large heterogeneous databases. The discovery of suitable, i.e. semantically-related data sources, is another critical issue, hindered by the lack of sufficient information on available datasets and endpoints. Browsing and searching data on such a scale is not an easy task. Semantic search can support the process aiming at leveraging semantics to improve the accuracy and recall of search mechanisms.
The Third International KEYSTONE Conference is a place where academic and industrial researchers can meet, disseminate scientific results, share new ideas and start joint research activities, all related to the challenges mentioned above. The goals are broader than those of traditional academic conferences. For this reason the usual presentation sessions that aim at disseminating new outcomes and training, are intermixed with brainstorming sessions aiming at promoting the discussion, inter/intra domain cross fertilization and at enabling new joint research activities among the partners. The conference is the last event organised by Cost Action IC1302 during which a special emphasis will be put in summarising and promoting goals reached during the project.
As an event organized by an EU COST Action, the participation in conference does not require any registration fees.
The Conference offers 2 tracks:
– Research Track, where regular papers will be presented
– Demo/Poster Track, where we invite for presentation the best experiences achieved thanks to the KEYSTONE Cost Action  IC1302 i.e. reports from STSMs, joint projects, research  developed during the action.
Contributions could fall within the following indicative topics, or other related.
– Keyword search on big data
– Keyword search on graph databases and the Semantic Web
– Use of Linked Data
– Information Retrieval
– Information discovery and extraction
– Development of techniques and tools for Search and Analytics
– Social Web
– Search-based interaction
– Privacy in keyword search
– Benchmarking for keyword search
Authors are invited to submit their work in the form of full research paper (max 12 pages), or a short paper (max 6 pages) or in the form of a demo/poster (max 4 pages). Demos/Posters should prefix the title of their submission with the word: “[Demo]” or “[Poster]”. Submissions should be done electronically using the easychair ( All research contributions should be original and not published elsewhere. The papers should be written in  english and formatted according to guidelines of  Springer’s LNCS/LNAI:
Accepted research papers will be published after the conference in the proceedings of Springer LNCS (confirmation pending). The publication of the papers in the proceedings is subject to the presentation in the conference by one of the authors.

3rd KEYSTONE School: Call for Speakers and Organizers

Posted by & filed under Calls.

The main theme for the 3rd KEYSTONE Summer School will revolve around the topics of Keyword Search and Big, Linked Data.
Big Data and Linked Data are becoming an important and integral part of the web infrastructure, where massive amounts of data are available, connected and identifiable via Uniform Resource Identifiers. The use of Big, Linked Data for organisational and enterprise purposes is considered to be one of the next big challenges in the evolution of the Web. Big Data takes account of the fact that new techniques and technologies are needed for the sustainable and socially balanced exploitation of huge data pools. The Linked Data paradigm is one approach to cope with Big Data, as it advances the hypertext principle from a web of documents to a web of rich data. Both branches are being described as crucial driving forces in the next generation economies.
There are numerous topics of interest that can be considered for the 2nd KEYSTONE summer school. The list can include (and is however not limited to) :

keyword-based navigation and search over Big,Linked data
quality of Big, Linked Data
semantic annotation and expansion for keyword queries
keyword query interpretation and disambiguation for Linked Data
fusing, cleaning, ranking and refining search results
scalability and performance of distributed queries
federated search over Big, Linked Data
clustering in support of keyword search over Linked Data
technologies for Big, Linked Data

The level of the lectures can be of an introductory, intermediate or advanced nature. Apart from lectures and hands-on sessions the event should also include a hackathon.
Expressions of interest to organise this event are now open. Interested parties should send an email to  and cc by Feb 18, 2017.
