| - | ===== Aspects of File and Data Synchronization ===== | ||
| - | |||
| - | With the ubiquitous use of mobile computational devices such as | ||
| - | laptops and PDAs, it has become increasingly important to be able to | ||
| - | synchronize data between these devices. To give a few examples: a new | ||
| - | appointment inserted in the calendar on a PDA must become visible on | ||
| - | the user's laptop after synchronization (and vice versa); files | ||
| - | modified on the laptop have to be synchronized with the Desktop | ||
| - | computer, and so on. But what do we do when an appointment is modified | ||
| - | on the PDA and at the same time deleted on the laptop? Dealing with | ||
| - | such conflicts is the main difficulty in designing good | ||
| - | synchronization software. | ||
| - | |||
| - | The goal of this thesis is to study, compare, and implement various | ||
| - | approaches to file and data synchronizers. This entails studying some | ||
| - | of the techniques used by distributed systems and version control | ||
| - | systems (such as CVS and Subversion), but also requires an | ||
| - | investigation of some more recent synchronization proposals like | ||
| - | Unison (http://www.cis.upenn.edu/~bcpierce/unison/index.html) and the | ||
| - | so-called "Lenses" proposed in the Harmony project | ||
| - | (http://www.seas.upenn.edu/~harmony). | ||

| - | =====Capturing Semantic Web Data from Web Pages===== | ||
| - | |||
| - | The [[http://linkeddata.org/|Linked Open Data]] (LOD) initiative is aimed at extending the Web by means of publishing various open datasets as RDF, setting RDF links between data items from different data sources. In spite of the interest of organization in publishing their data, many of them are not willing to pay the price of devoting working hours or their employees for doing the hard work that preparing and updating these data requires. Therefore, a very interesting and practical problem that arises is how to produce LOD automatically from Web sites. This problem can be tackled if selected and well-defined domains are chosen. | ||
| - | |||
| - | |||
| - | In his thesis we propose to select a site of a broadcasting company, and, through intelligent crawling techniques capture data of interest and publish it as RDF data. In a second step, we propose to use these data to pose queries that involve different nodes of the Web of linked data. | ||
