Assistance in retrieving of documents on the World Wide Web is provided either by search engines, through keyword based queries, or by catalogues, which organise documents into hierarchical collections. Maintaining catalogues manually is becoming increasingly difficult due to the sheer amount of material, and therefore it will be necessary to resort to techniques for automatic classification of...

Link analysis on Web graphs and social networks form the foundation for authority assessment, search result ranking, and other forms of Web and graph mining. The PageRank (PR) method is the most widely known member of this family. All link analysis methods perform Eigenvector computations on a potentially huge matrix that is derived from the underlying graph, and the large size of the data make...

The term “spam,” as applied to unsolicited commercial email and related undesirable online communication, derives from a popular Monty Python sketch set in a cafe that includes the cannedmeat product SPAM in almost every dish. As the waitress describes the menu with increasing usage of the word “spam,” a group of Vikings in the cafe start singing, “Spam, spam, spam, spam, spam,” drowning out al...

We develop a technique we call spectral filtering, for discovering high-quality topical resources in hyperlinked corpora. Through relevance and quality judgements collected from 37 users, we show that, over 26 topics, spectral filtering usually finds web pages that are rated better than those returned by the hand-compiled Yahoo! resource list, and by the Altavista search engine.

In the paper we introduce intermediate results of building domain ontology for describing food and food products. The ontology we’re building extends the most powerful ontology for product and service domains GoodRelations which is used by big companies such as Google, Yahoo, Best Buy and others. We give an overview of the relevant conceptual entities and relationships in the domain.

The work described in the thesis proposes a Geodistributed key-value datastore, named ChainReaction, that offers causal+ consistency, with high performance, fault-tolerance, and scalability. ChainReaction avoids the bottlenecks of linearizability while providing competitive performance when compared with systems merely offering eventual consistency. We have experimentally evaluated the benefits...
