Annual Reports

2002. During the last year I have finalized the topics of the PhD thesis. Specifically, for what concerns the structural similarity, I have computed the time complexity, experimentally validated the proposed approach, and devised applications of the measure [BGM03b]. Moreover, I have exploited the use of Word Sense Disambiguation Techniques for automatically associating with each tag of a document/DTD the corresponding meaning [MRM02,BMR03]. Disambiguated tags are then employed for allowing tag similarity instead of tag equality in measuring the structural similarity. For what concerns the evolution of DTD structure, I have exploited the possibility of employing datamining association rules for extracting the new structure of a DTD element by relying on the structure of the elements classified against it. Furthermore, combining some ideas developed in the context of datawarehousing [CMM00] with work on temporal databases of the database group we have developed an approach for the expiration of temporal values at a given granularity and their aggregation at coarser granularities [CBG02,CBG03].
2001. During the third year I have worked on different topics related with the PhD thesis. First, in the area of access control policies, facilities for helping the Security Officer to define access control policies for sources of XML documents have been developed [BCF02]. Then, an approach for measuring the structural similarity between an XML document and a DTD has been investigated. Such a measure can be exploited for the classification of XML documents against a set of DTDs and for grouping together documents having similar structure [BGM02a,BGM03a]. Finally, an approach for evolving the structure of a set of DTDs to the current documents of a source has been developed [BGM02b]. Results obtained in these investigations have been reported in the phD working status report ("stato di avanzamento"). A paper containing the main goals of the phD thesis, the current status of the research, and the plan for next year have been submitted to the workshop of PhD Student in Database area of EDBT conference [Mes02]. Furthermore, the rule-based mechanism for routing messages, developed during the second year, has been implemented thanks to the help of two master students [BCM03,BCM02]. In May, I and the two students spent two weeks at the Telcordia Labs. in New Jersey, for integrating the prototype in one of their project.
2000. During the second year I have worked on access control mechanisms for selective and secure dissemination of XML documents over the Web [BCF00,BBC00]. Moreover, during the period spent at Telcordia Technologies I have started investigating the possibility of representing in XML components of a telecommunication network and issues related with their representation in traditional database model. Furthermore, during the period at Telcordia I have been involved in a telephony project. The project is related to the definition of a universal communication identifier (UCI) associated with a user independent from the devices he/she has. In this framework I have developed a mechanism based on rules for routing a message arriving at the UCI associated with a user to his/her devices [BCM00]. A work about application of datawarehousing techniques to monitor network traffic developed in the past at Telcordia has been published [CMM00].
1999. During the first year I have worked on classification approaches for semi-structured data in an object-oriented data model continuing work done on this topic in the master thesis. Moreover, I have started investigating topic related to XML (eXtensible Markup Language) since XML documents are good examples of semi-structured data on the Web. In the area of XML I have investigated the problem of classification against a set of DTDs and
