Call For Papers

1st International KEYSTONE Conference (IKC 2015) - CFP
Coimbra Portugal
8-9 September 2015

The first International KEYSTONE Conference (IKC 2015) is organized by EU funded COST Action IC1302 "KEYSTONE - semantic keyword-based search on structured data sources". As an event organized by a COST Action, the participation in the conference does not require any registration fees. Nevertheless, the participation is subject to registration: a limited numbers of seats will be made available.

Participation is open to all interested people.

IKC 2015 is a place where academic and industrial researchers can meet, disseminate scientific results, share new research issues, start joint research activities. The goals of IKC 2015 are larger than those of traditional academic conferences. For this reason we will combine the usual presentation sessions (to achieve the state of the art and disseminate new outcomes) with brainstorming sessions (promoting the discussion, inter/intra domain cross fertilization and enabling new joint research activities among the partners).

The first KEYSTONE Conference has 4 tracks:
- Research Track
- In-use Track
- Challenge Track
- Help me Track.

Research track CFP

Since large-scale data sources are usually comprised of a very large schema and billions of instances, keyword search over such datasets can suffer from 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 heterogeneous databases that are composed of thousand

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 for users. Semantic search can support the process aiming at leveraging semantics to improve the accuracy and recall of search mechanisms.
The theme of the conference is about keyword search on massive data sets and all the topics that surround it. This list includes (but is not limited to) :

- Highly scalable techniques for keyword search
- Keyword search on large graphs
- Keyword search semantics
- Open Data Exploitation for information discovery at large
- Interplay between Analytics and Search
- Semantic similarity, management, disambiguation and indexing
- Social Web and social media;
- Keyword search over privacy preserving data
- Modern interfaces for keyword search and result presentation on Big Data
- Benchmarking for search on Big Data.
- Knowledge / ontology exploitation for efficient and effective search

In-Use Track CFP

Keyword-based search over structured and semi-structured datasets is increasingly deployed in synergy with other technologies, particularly from the fields of semantic web, information retrieval, data mining and databases, to support real-life applications. The In-Use track provides a forum for the community to explore techniques, tools and libraries that can be used in such settings. We expect the submissions that showcase the benefits and pinpoint challenges of applying techniques from the database, semantic web, data mining, natural language processing, IR and related fields, which may be developed by the authors themselves or other third party, e.g., academics or industrials, to search, explore and exploit Web data. We particularly encourage submissions that contain a form of demonstration, albeit optional.

Submissions will be evaluated on the practicality of the tool, method or technique, subject of the submission, its relevance to the community. Submissions should clearly describe the problem addressed, preferably using a use case or illustrative example, and show how the solution (method, technique, library, etc.) can be used for its resolution.

Accepted submission will be made available online. They will not be included in the proceedings. (to be confirmed) Authors will be allocated 20 min (including QA and discussion) to present their work. The presentation and supplement materials such as: demonstration videos, source codes will be incorporated into github repository as well as published at the KEYSTONE website.


Papers submitted to this track (2 pages) will be published in the proceedings.

- Submission deadline: June 1

Challenge Track CFP

Challenges Track is a fully interactive session on the open issues and research challenges in development of keyword search techniques. What open issues do you see? What unresolved keyword search problems are you facing?

Any challenge in the scope of KEYSTONE project interests is welcome.

The goal is to:

- foster joint research ideas and proposals which are needed in the KEYSTONE COST action (STSM networking, joint publications etc.) and
- identify interesting (i.e. open) research issues


Challenge Track will be organized in a form of talks. Talks include 5 minute presentation with 10 minutes of feedback and in-depth discussion from the audience. Talks (presentations) must be prepared jointly by at least two partners from different countries.


Papers submitted to this track (1 page abstracts) will be published in the proceedings or at the web page of KEYSTONE Open Conference (authors will express their choice of preference).

Help me Track CFP

This track is particularly oriented to ECI (Early Career Investigators, (8 years after the PhD) and PhD students. The main goal of the track is provide them with the opportunity to present their research (through a poster or a short presentation) and to discuss it with the attendants and senior researchers.

How to participate:

If you are a PhD student, a ECI or a group of them and you have just started an independent research career and would like to get some pieces of advice and/or collaboration on topics related to KEYSTONE, then you are invited to submit a maximum of 4 pages describing your work in progress or a position paper with ideas you want to develop.

All submissions will be evaluated by at least three reviewers and around 6 of them will be selected to be presented at the conference.

Presentation in the conference:

The selected works will be presented at the conference. The presentation will consist of two parts: The four Minutes Madness and a Traditional poster presentation.

Four Minutes Madness is a fun event oriented to teams or individual ECI and/or PhD students to present their research in 4 minutes. Each presenter/team can use some slides to help them during this short presentation (a projector, a computer, and a remote control to navigate through the slides will be available on the floor). After 4 minutes, the team/presenter must leave the floor (escorted if necessary) and the next presenter/team begins. The running order will be established and published in advance by the organization committee.

The total duration of the four Minutes Madness will be 25-30 minutes and the main goal of each team/presenter should be to capture the attention of the attendees so that they and senior researchers in KEYSTONE visit their slots to discuss with them, provide them with some feedback and/or establish some type of collaboration.

After the Four Minutes Madness every team will go to an assigned slot (desktop) where they will receive the visits of the interesting attendees and researchers during 1 hour. Each slot will have a place for an A1 poster, a power strip to plug computers and a table.
