LiquidPub: Services at the service of

scienceMarcos Baez, Fabio Casati , and the LiquidPub

teamDepartment of Information Engineering and Computer Science

University of Trento

ECOWS 2009 – Eindhoven, The Netherlands – 10 Nov 2009

In a nutshell: the goal

Capture the lessons learned and opportunities provided by the Web and open source, agile development to develop concepts, models, metrics, and tools for an efficient (for people), effective (for science), and sustainable (for publishers and the community) way of creating, disseminating, evaluating, and consuming scientific knowledge. Understand what’s good for science, and make it happen

project.liquidpub.org

•Publish and perish: why the current publication and review model is killing

research and wasting your money (ACM Ubiquity 8(3), Feb 2007), and

•Liquid Publications: Scientific Publications meet the Web

With Fausto Giunchiglia and Maurizio Marchese.

Objective

Understand

Dissemination models and

overhead

Evaluation processes, and

quality/impact of research

(people, papers, projects)

Peer review and

innovation

Scientific communities

Funding models and

processes

Improve

Better ways to do the

Fairness

Definition: A review process is fair if and only of

the acceptance of a contribution does not

depend on the particular set of PC members

that reviews it

The key is in the assignment of a paper to

reviewers: A paper assignment is unfair if the

specific assignment influences (makes more

predictable) the fate of the paper.

Principles and objectives

Everything counts!! (not just papers, not just ―innovations‖)

Minimal dissemination overhead

Early sharing

Early feedback/interaction

Find diversity

Interestingness and sharing as measures of reputation

No gatekeeping. Use the filtering power of the community

We are not necessarily right!! Let the community select the principles and models

Model:

3. What you can do with it

project.liquidpub.org Fabio Casati - ECOWS 2009 27

2. How it gets filled…

Can be edited, but can be (semi-)automated

Topics and tags (+ tags by specific people)

Subscriptions/preferences

Journals—editing power of the community!!

Authors

Wisdom of people you trust (as editor)

Wisdom of the crowd (if any)

Diversity!!!

Results

Everybody becomes a journal editor (selfishly)

No gatekeeping, quality enforced by the community (gatekeeping is the noise)

You get things you want to read (or you want your group to read)

You get diversity

You leverage the selection work of your friends

Measure interestingness and quality by sharing

Reduce (optimize) dissemination overhead and encourage early sharing

IT Services: LiquidPubinfrastructure

project.liquidpub.org Fabio Casati - ECOWS 2009 30

Engineer a system that

Accesses heterogeneous src w/ no API

Is modular so that functions can be reused

In a world where modularity had little success

Facilitates the creation of arbitrary dissemination and evaluation models (by non-programmers)

Provides commonly needed research services

Implements liquid journals (agile – our main macro-story)

Simple and lightweight

Take-Home Message

Flaws of current practices (or, lack of evidence

that they work as expected)

Research services for novel dissemination model

Principles, models, composable IT services in a

restricted domain

Liquid journals: Interestingness, reward

innovation, sharing, everything contributes, use

the filtering power of the community
