Mini book review: Principle of Health Interoperability

Principle of Health Interoperability (SNOMED CT, HL7 and FHIR) Tim Benson and Grahame Grieve (3rd edition) The biomedical data landscape is very broad, and as such it presents many different data standards and terminologies. Nevertheless, as different areas of science and healthcare are converging, it is common for data practitioners to get in contact with data standards from related fields. For anybody coming from a bioinformatics background, it is usually hard to make a coherent map of healthcare standards. Many

The difference between a Knowledge Base and a Database

I have always felt a bit uneasy to say that I am working in “Knowledge Management”. “Knowledge” is such a big word, that I always wonder what my interlocutor (or reader) think “Knowledge Management” is. So I found myself recalling a conversation going like: “I am building a Knowledge Base” and receiving as an answer: “so you are building a database?”. The difference is intuitively obvious to me, but how can I simply explain it? Of course I could present

Neural Networks driven Fuzzy Reasoning

Yesterday my son (who is 8 months) was “playing” with one of my computers (playing consisting mostly of banging the keyboard). It was a fresh installation, so I didn’t pay much attention. When I had a look at the screen, I saw one document open: it was an old work I did as part of an undergraduate course “Neural Network Reason Fuzzy Reasoning” (sort of a report on some soft computing techniques). It must have been in a dropbox folder

SWAT4LS: 10 years after

SWAT4LS (Semantic Web Applications and Tools for Life Sciences) will be held this year in Rome, Dec. 4th-7th. This year marks the 10th consecutive year for SWAT4LS, and this calls for a little retrospective on its history. That is this post, from my perspective as a co-organizer. I think the origin of the workshop can be traced to a Nettab workshop: A Semantic Web for Bioinformatics: Goals, Tools, Systems, Applications. The following year, Paolo Romano, who was organizing Nettab, suggested to have a

The role of the data modeler

Originally posted on Linkedin. I have been developing “data models” in a few occasions, but I always found it difficult to define, exactly, what I was doing as a “data modeller”. So this post is an attempt to explain to myself, and perhaps to discuss with others, what being a data modeller is about. At least from my experience. Perhaps this can be reduced to a simple question: what does doing a data model look like? Is it like designing

While I don’t have much time anymore to write papers, a list my main publications are indexed by Research Gate.

Some of the presentations I gave  are available on slides share.
