Prof. Massimo Marchiori
DISTINGUISHED ADVISOR, AI RESEARCH

​Massimo has advised Loop AI Group since 2014, bringing rare insight into the foundational architectures of machine intelligence and web-scale information systems. The creator of HyperSearch—the algorithm that inspired Google's PageRank—and a principal architect of web standards including P3P, XQuery, and OWL at Tim Berners-Lee's W3C, Massimo has shaped how the world organizes, queries, and reasons over information. His guidance has been instrumental in grounding Loop's cognitive technology in rigorous first principles.

Prof. Massimo Marchiori is an Italian mathematician and computer scientist who is a Professor of Computer Science at the University of Padua, a Research Scientist at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) within the World Wide Web Consortium (W3C), and the Chief Technology Officer of the European Institute for Science, Media and Democracy (Atomium Culture), the Permanent Platform for European Excellence. In July 2004, he was honored with the TR35 prize by MIT Technology Review as one of the 35 top researchers in the world under the age of 35.


Marchiori is internationally recognized as a seminal figure in the development of search engine technology. He developed the concept of "hyperinformation" and formulated the HyperSearch algorithm, which he presented at the Sixth International World Wide Web Conference (WWW6) in Santa Clara, California in April 1997. His paper, "The Quest for Correct Information on the Web: Hyper Search Engines," introduced the revolutionary concept of ranking search results based not only on single page content, but on the relationship between individual pages and the entire web—the first search engine to do so.


Following his presentation in Santa Clara, a 23-year-old Larry Page, who was in the audience, sought out Marchiori and spent the day discussing algorithms with him. According to Marchiori, Page said, "Man, I would like to develop your idea further." The following year, Google co-founders Larry Page and Sergey Brin cited HyperSearch when they introduced their PageRank algorithm in their seminal 1998 paper, "The Anatomy of a Large-Scale Hypertextual Web Search Engine," and subsequently in their PageRank patent (U.S. Patent 6,285,999), which was assigned to Stanford University. Wikipedia notes that "PageRank was influenced by citation analysis, early developed by Eugene Garfield in the 1950s at the University of Pennsylvania, and by Hyper Search, developed by Massimo Marchiori at the University of Padua." Marchiori has stated that Google's founders "have always acknowledged his contribution to the Google formula" and that he harbors no regrets about not participating in their commercial venture.


Marchiori was appointed as Research Scientist at MIT by Tim Berners-Lee (the inventor of the World Wide Web) himself, and has worked closely with him on developing the foundations of the Semantic Web. He is a member of the board of Tim Berners-Lee's World Wide Web Consortium (W3C).
Massimo is the creator of several world-impact technologies, including:


P3P (Platform for Privacy Preferences): The global standard for web privacy. Marchiori served as Chief Editor of the P3P specification.


XML-Query (XQuery): The world standard for semi-structured data handling. Marchiori was the initiator of the Query Languages effort at W3C (chairing QL'98) and started the XML-Query project, for which he served as W3C contact for many years. He received the Lifetime Membership Award from the Oxford Society for his lifetime achievements and efforts in developing the XML Query standard.


Web Ontology Language (OWL): The world standard for web knowledge representation.


APPEL: The proposed world standard for privacy selection; Marchiori is co-author of the APPEL specification.


Metalog: The world's first semantic web system (1998), developed in collaboration with Tim Berners-Lee. Metalog allowed querying and reasoning for the Semantic Web using a pseudo-natural language interface.


Volunia: The world's first social search engine and meta mappings system. Launched in beta for registered "power users" on February 6, 2012, and went live on June 14, 2012. Volunia introduced a "fly-over" map visualization for websites and allowed users to interact with each other on any page they visited. The name derives from the Italian words "volo" (flying) and "luna" (moon).


SEP (Search Engine Persuasion): The world's first formal study on what is now known as Search Engine Optimization (SEO).
Hyperinformation: The world's first "hyper" technique for search engines.


HyperSearch: The world's first hyper search engine, a forerunner to Google.


Marchiori is also the Editor-in-Chief of the Open Journal of Web Technologies (OJWT) and serves as a co-founder and Executive Committee member of the European Commission Network of Excellence on Web Reasoning, REWERSE. He has served as W3C's responsible for the IEEE Internet Best Practices Activity.


His accolades include the Gini Foundation Award for innovative research, the IBM Young Scientist Award, the Lifetime Membership Award from the Oxford Society for his lifetime achievements and efforts in developing the XML Query standard, and the Masi Award.


Massimo has tackled several significant open research problems, including the longstanding modularity problem in rewriting systems (published in Journal of Symbolic Computation), the existential termination problem in logic programs, and the constrained evolution of neural networks.
He holds a Ph.D. in Computational Mathematics and Computer Science from an Italian university, with a thesis that won the EATCS (European Association for Theoretical Computer Science) Best Ph.D. Thesis Award for the invention of local analysis in programming languages. Prior to the University of Padua, he was a research scientist at CWI (the National Research Institute for Mathematics and Computer Science in the Netherlands) and served as a professor at Ca' Foscari University of Venice.
