Data extraction from the web

I'm an expert on regular expressions, spiders/crawlers (web scraping / data mining) and databases (MySQL, MSSQL, PL/SQL, SQLite, H2) with more than 15 years of experience in collecting large amount data from the web (from tens of millions of pages per month). My experience include extracting data from large sites like Amazon, Tripadvisor, Yelp, Booking, Google Maps, LastFM, Goodreads, IMDB and others. I have experience in algorithms for detecting similarity and equality and prediction algorithms. I can help with my server administrator skills (Debian/Ubuntu).

Universal Interpersonal Communication Application Prototyping

2023 31st National Conference with International Participation (TELECOM)
This paper describes a mobile application prototype built on the UICA architecture to test the UICA concept in practice. The prototype considers the security issue of managing multiple credentials and implements two of the five UICA communication categories using MTProto (Telegram) and XMPP protocols. It proposes unified interfaces for communication technologies and includes a UICA mechanism for selecting "best" communication service based on context.

An Architecture for Creating Universal Interpersonal Communication Applications (UICAs)

2022 30th National Conference with International Participation (TELECOM)
This paper describes a generic architecture for the creation of universal interpersonal communication applications (UICAs) capable of selecting the ‘best’ service for communication with particular person(s), depending on the current context, based on the calculated service ratings considering different evaluation criteria. A suitable service categorization, serving the UICAs, is proposed. The relevance of the UICA approach to a user-centric realization of the ABC&S paradigm is highlighted.
