[iks-community] Introducing myself and the Semantic Scouting demo

[Alfio Massimiliano Gliozzo]

Dear all,

I’m Alfio Massimiliano Gliozzo, researcher at the Semantic Technology  
Laboratory of the Italian National Research Council (CNR) where I  
coordinate the Natural Language Processing and Information Retrieval  
area. You can find additional info about me and my lab here (http://stlab.istc.cnr.it/stlab/User:AlfioGliozzo 
).

My main research topic is hybridizing Information Retrieval, Natural  
Language Processing and Machine learning approaches with knowledge  
management tools at scale. One of the applications I’m interested in  
is Knowledge Retrieval, which is about retrieving structured knowledge  
relevant for natural language queries. This task can be performed on  
large RDF/OWL knowledge bases.

I will present an application of knowledge retrieval in the next IKS  
workshop “Semantic Search - Fact and Fiction” in Rome. This is a  
semantic search engine called “Semantic Scouting” working on an RDF/ 
OWL ontology describing the CNR organization, developed as a  
collaborative work by almost all members of my lab as a showcase for  
the capabilities we are currently developing here.

CNR is the largest research institution in Italy, employing more than  
20k researchers, organized into departments and institutes, subdivided  
into research units characterized by different competences, research  
programmes, and laboratories. We performed a migration of the  
information spread into different CNR databases into a common RDF/OWL  
knowledge base containing both texts (e.g. the titles of the papers  
wrote by any researcher) and structured data (e.g. relations between  
researchers and their institutes) [1]. The result is a critical mass  
of data representing around 30k instances organized into 50 classes  
and 1.8M triples.

Further, we expanded the knowledge base by performing some simple  
inference (e.g. the co-authorship relation) and we automatically  
generated relations with linked open data resources, and in particular  
DBpedia categories, by exploiting advanced text processing techniques.

Then we developed a knowledge retrieval engine whose output are  
entities of different types, where the input are queries in either  
Italian or English language. Using such entities as entry points, we  
can further explore the ontology following two different modalities:  
browsing the graph of relations around each entity or opening forms  
representing relevant attributes and relations.

The result is a running system that I’ll show at the workshop and  
will be delivered soon as a service within the CNR intraweb.

Looking forward to meeting you all in Rome,
