## 6 Demonstration and Results
### Results of Mapping the Concepts from a New Source to Existing Concepts in the Ubiquitous User Model
For the set of neighbors \(N_{s}\) from the source XML document hierarchy \(H_{s}\), the concept labels of the ancestors of \(c_{s}\) and direct brother who share the same immediate parent element and are terminal elements are selected. The set of neighbors \(N_{T}\) from the ubiquitous user model hierarchy \(H_{t}\) is populated with the labels of the target concepts the sub collection in which the best suited concept for alignment \(c_{tb}\) is a member. \begin{table}

Table 3: Partial view of similarity matrix (XML Document concepts, ubiquitous user model concepts). A sample of the sets of neighbors generated in structure level matching process is presented in Table 4. Notice that the labels of the brother concepts are concatenated with a prefix of the direct parent. With this strategy, we are aiming to add more expressivity to the labels of commonly used generic labels. Once the sets of neighbors are generated, the system processes proceeds to the calculation of a new similarity matrix, based in element level matching and equation 4, between the two sets of neighbors \(N_{s}\) and \(N_{T}\).
