Recovering traceability links in multilingual Web sites

The problem of verifying the consistency between Web site portions devoted to different languages is investigated. The purpose is to support the activity of the site maintainer, who is responsible for the alignment between different site versions. Anomalies that typically occur in such situations include the absence of pages in some languages, differences in the page structure in different languages, missing information and parts not translated. The approach which is proposed for recovering traceability links so as to simplify the update of the site to a consistent state, is based on a mix of structural and textual information extracted from the page. The syntax trees of the pages to be compared drive the page matching process. When structurally corresponding nodes are encountered during the tree visit, their text attributes are considered to see if they are each other's translation.
