Explore instead of Searching!

Creating expert profiles from documents using semantic technologies

Document fingerprints aggregated to expert profiles!

BiomedExperts – more than 300,000+ registered users

Prepopulated network – based on PubMed

1.8 million precalculated experts

More than 24 million co-author relations between them

Representing over 3,500 institutions

From 190 countries

Growing each day between 500 and 1000 users

BME data used in other applications

Co-author based

networks

Geographical

mapping of the

co-author network

Johns Hopkins: The Issue! Connecting Experts

Fall retreat: Main issue how do they take advantage of the

university’s expertise and build collaboration

First solution – Repurpose a parking lot to be a coffee shop

for the JH community to grab a cup of Joe and find new

collaborators.

Outcome – Great coffee, great conversation but

collaboration did not take off.

The Collexis Solution – Expert Institutional Dashboard!

Same Application for the NIH

AsklepiosFacts and Figures

• Asklepios - Europe‘s largest health care provider

– 500.000 patients for inpatient care per year, 95 hospitals, 21.000 beds– 34.500 employees– Asklepios owns medical nursing and allied health schools– Home care programs and residential care programs

• Asklepios International – Pacific Health System – California– Greece, Athens Medical Center– University hospital in Shanghai: Joint Venture with Siemens and Tongji University

Optimize Workflows (e.g. Avoid interruptions

caused by knowledge search, retrieval, and application)

Distribute Expert Knowledge

(across multiple locations, time zones, medical

conditions)

Guide Workflows(e.g. Care Plans, Expert-Task Context Allocation)

Help Asklepios to know “what Asklepios knows”

Stimulate new Knowledge Acquisition Usage

Models

Why Knowledge Management?

• Patient, male, age of 62, needs a knee joint prosthesis due to Rheumatoid Arthritis

• Where is the best place to get it?

• Criteria which will be taken into account:– Geographical aspects– Recommendation of his GP– Publicly available information - mostly via Internet

• Strongest competitors: university hospitals (within the region)

Use Case 1 – Expert profiles

Asklepios Research Profiles

Expert Profile of Prof. Grifka

Make Internal Expertise available!

Provide a single point of search for all relevant content from

publishers!

Link internal expertise / experience and external

knowledge sources!

Provide a single point of search for all relevant content from

publishers!

Link internal expertise / experience and external

knowledge sources!

• Patient with lung cancer and reduced renal function

• Decision in chemotherapeutic drug is pending

• Preferred choice: Cisplatin as chemotherapeutic agent

• Open questions: can Cisplatin be used which has nephrotoxicity as a side effect?

Use Case 4 - External Resources and Internal Experience Use Case 4 - External Resources and Internal Experience

Search - Cisplatin shows the relevant publications from Springer, Elsevier, Thieme, OVID and other publishers

Asklepios Intelligent Digital Library

Opening an journal article…

…shows immediately similar publications colleagues

… and the names and expert profiles

Link External Knowledge and

Internal Expertise

Key Issues in STM IndustryPublishers / Editors

Finding the right reviewer

Expanding their pool of reviewers

Institutions

Determining what grants they should go after

Determining who within their organization is best to apply

Grant Funding Organizations

Analyzing the vast amount of grant applications submitted.

Determining who within the organization is best qualified to review the grant application

(known and unknown)

The Challenge for STM PublishersReceive thousands of manuscripts annually

Timely process to conduct the Peer Review Process

Timely process to determine who should review it.

Important for reviewer to free of conflicts of interest

Ethics of review process are paramount

Key Benefits Reviewer FinderFingerprint of manuscript - Clarity

Determine the best reviewer

Free of conflicts

More efficient and effective process

Ultimately increases profitability

The effectiveness of Semantic Technology

Aggregates the researcher's publications into a Fingerprint of weighted

relevant concepts

Expert Profiles (individual, institution, dept, country,etc.)

Shows co-author relationships (who publishes with whom)

Conduct search by key concepts

Match content from a variety of sources based on a key concept,

researcher, country, etc.

Determine expert for peer review, grant application, project, etc.
