WebDocs: a real-life huge transactional dataset
Lucchese C., Orlando S., Perego R., Silvestri F.
This short note describes the main characteristics of WebDocs, a huge real-life transactional dataset we made publicly available to the Data Mining community through the FIMI repository. We built WebDocs from a spidered collection of web html documents. The whole collection contains about 1.7 millions documents, mainly written in English, and its size is about 5GB.Source: ICDM Workshop on Frequent Itemset Mining Implementations, pp. 2–2, Brighton, UK, 1 November 2004

Rights protection of trajectory datasets
Lucchese C., Vlachos M., Rayan D., Yu P. S.
This work presents a technique of convincingly claiming ownership rights over a trajectory dataset. The presented methodology distorts imperceptibly a collection of sequences, effectively embedding a secret key, while retaining as well as possible the neighborhood of each object, which is vital for operations such as similarity search, classification or clustering.Source: 24th International Conference on Data Engineering, pp. 1349 -–1351, Cancún, Mexico, 7-12 Aprile 2008

ExAMinerGEN
Bonchi F., Lucchese C.
ExAMinerGEN: è un software per il mining di pattern frequenti capace di sfruttare tutti i vincoli studiati ad oggi in letteratura. Il software `e implementato utilizzando lo stato dell'arte delle tecniche per il pushing di vincoli nell'estrazione di pattern frequenti. Il software è efficiente, robusto, data aware (adatta il suo comportamento ai dati in analisi) e resource-aware (passa in memoria principale, cambiando strategia di mining, non appena il database di input è stato ridotto a sufficienza rispetto alle risorse disponibili). ExAMinerGEN è il motore di mining utilizzato dal sistema ConQueSt.

Discovering Europeana Users' Search Behavior
Ceccarelli D., Gordea S., Lucchese C., Nardini F. M., Perego R. Tolomei G.
Europeana is a strategic project funded by the European Commission with the goal of making Europe's cultural and scientific heritage accessible to the public. ASSETS is a two-year Best Practice Network co-funded by the CIP PSP Programme to improve performance, accessibility and usability of the Europeana search engine. Here we present a characterization of the Europeana logs by showing statistics on common behavioral patterns of the Europeana users.Source: ERCIM news 86 (2011): 39–40.

VISITO - Componenti per l'estrazione delle features dalle immagini
Lucchese C., Venturini R.
La ricerca efficiente di informazioni utilizza tecniche di indicizzazione dei dati al fine di soddisfare efficientemente ed efficacemente le interrogazioni sottomesse dagli utenti. In pratica gli indici rappresentano un'astrazione delle informazioni basata su bag-of-feature, l'insieme cioè delle caratteristiche più importanti (feature) di un generico oggetto, sia esso un documento testuale o un oggettomultimedialequaleunafotografiadigitale.

Pushing tougher constraints in frequent pattern mining
Bonchi F., Lucchese C.
In this paper we extend the state-of-art of the constraints that can be pushed in a frequent pattern computation. We introduce a new class of tough constraints, namely Loose Anti-monotone constraints, and we deeply characterize them by showing that they are a superclass of convertible anti-monotone constraints (e.g. constraints on average or median) and that they model tougher constraints (e.g. constraints on variance or standard deviation). Then we show how these constraints can be exploited in a level-wise Apriori-like computation by means of a new data-reduction technique: the resulting algorithm outperforms previous proposals for convertible constraints, and it is to treat much tougher constraints with the same effectiveness of easier ones.Source: Advances in Knowledge Discovery and Data Mining, Pacific-Asia, pp. 114–124, Hanoi, Vietnam, 18-20 May 2005

On condensed representations of constrained frequent patterns
Bonchi F., Lucchese C.
Constrained frequent patterns and closed frequent patterns are two paradigms aimed at reducing the set of extracted patterns to a smaller, more interesting, subset. Although a lot of work has been done with both these paradigms, there is still confusion around the mining problem obtained by joining closed and constrained frequent patterns in a unique framework. In this paper we shed light on this problem by providing a formal definition and a thorough characterization. We also study computational issues and show how to combine the most recent results in both paradigms, providing a very efficient algorithm which exploits the two requirements (satisfying constraints and being closed) together at mining time in order to reduce the computation as much as possible.Source: Knowledge and Information Systems 9 (2006): 180–201.
