ESWC2016 Workshop PROFILES’16 on Dataset Profiling and Federated Search for Linked Data

Posted by & filed under Calls.

Venue: PROFILES 2016 is co-located with ESWC 2016 and takes place in Anissaras, Crete, Greece.
Date: PROFILES 2016 will take place on Monday, May 30, 2016.
The PROFILES’16 workshop aims to gather innovative query and search approaches for large-scale, distributed and heterogeneous
linked datasets inline with dedicated approaches to analyse, describe and discover endpoints, as an inherent task of query distribution.
PROFILES’16 will equally consider both novel scientific methods and techniques for querying, assessment, profiling, and curation of
distributed datasets as well as the application perspective, such as the innovative use of tools and methods for providing structured
knowledge about distributed datasets, their evolution and fundamentally, means to search and query the Web of Data. The workshop will
provide a highly interactive forum for researchers in the fields of Semantic Web and Linked Data, Databases, Semantic Search, Text Mining,
NLP and Information Retrieval.
The main areas of interest of PROFILES’16 include dataset/endpoint analysis, profiling and discovery along with techniques for distributed
semantic search that take such profiles into account. In particular this includes:
Dataset/endpoint analysis, profiling and discovery:
dataset profile representation (vocabularies, schemas)
novel applications and techniques for dataset profiling
automated approaches to dataset analysis and exploration
analysis/monitoring of dataset and graph dynamics
topic profiling of datasets
assessment of dataset schema conformance and evolution
dataset quality analysis for query routing
Distributed semantic search:
query routing taking into account relevance and quality of distributed datasets
semantic annotation and expansion for keyword queries
keyword query interpretation and disambiguation for Linked Data
fusing, cleaning, ranking and refining search results
scalability & performance of distributed data queries
novel applications for federated search over Linked Data
We welcome the following types of contributions.
Short (up to 6 pages) and full (up to 15 pages) research papers
Poster abstracts and system demonstrations should not exceed 4 pages

Call for the organization of the Second KEYSTONE Conference

Posted by & filed under Calls.

The KEYSTONE COST Action is going to organize the second KEYSTONE Open Conference in Sept – Nov 2016. The Management Committee of the Action decided to open a call to select the team in charge of the organization of the conference, its specific topic, and the “structure” of the event.
The KEYSTONE WG members interested in the organization of the event should send their proposal via email to by Feb 21.
The applications will be evaluated by the KEYSTONE MC in the 5th MC Meeting in Marseille France on 22 February.
To support the organization of the proposals a spreadsheet is available in google drive
If you would like to participate in the organization, but you don’t want to be the main responsible, you can collaborate with other WG Members. In that case, you should write in the spreadsheet which is your specific availability and you could be asked to enter in one of the proposal coordinated by other KEYSTONE WG members. If you want to candidate your city as the place where to organize the conference, include this in the spreadsheet.
The proposal should include the following details:
1. Organizers / Team
This refers to the General chair, Program chair and the other leading positions.
The organizers have to be at least from 2 different countries among the ones participating in KEYSTONE
2. Conference theme and topics addressed
The Conference theme and topics addressed should be consistent with the main objectives of the general theme “semantic keyword search in structured data sources”, with particular reference to the semantic web. Main research topic could be:
1. Development of techniques and tools for search and analytics;
2. Study of scalable techniques;
3. Application of semantics;
4. Use of (linked) open data.
3. Structure of the event
The MC has previously suggested organizing a conference that should not follow the typical research conference “pattern”. The conference should:
a. Couple traditional presentation sessions (to achieve the state of the art and disseminate new techniques) with brainstorming sessions (to promote the discussion, inter/intra domain cross fertilization and enabling new joint research activities among the partners).
b. Promote the participation of industrial partners to provide keynotes about their research needs and possible applicative scenarios.
In this section, the applicants should shortly describe the “structure” of the conference they plan to organize, including the number and features of the presentation sessions, the number and features of the brainstorming sessions, and whether they plan to organize tutorials, keynotes, “competitions”, poster sessions, …
4. Location
The proposers should indicate if they have already contacted a Local Organizer or if they need a support for deciding the location.
5. Timing
The conference will take place in summer/winter 2016. The applicants should define the timing of the main steps (issuing the call, deadline for the paper submissions, notification, …)
6. Visibility / Dissemination
The proceedings of the first editions have been published by Springer. The organizers should manage the contacts with Springer for the publication of the current ones. The proposers should indicate if they plan to organize special issues in international journals including  the best papers.
7. Early Career Investigators –ECIs-
One of the COST policies is related to Early Career Investigators, who should particularly benefit from a COST Action. Is there any activity addressed for increasing the involvement / participation of ECIs?
8. Gender Balance
One of the COST policies is related to Gender Balance. Is there any activity addressed for increasing Gender Balance? Is the proposal (in terms of organizers) balanced?

2nd KEYSTONE Summer School: call for volunteers

Posted by & filed under Calls.

The main theme for the 2nd 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
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
