“…In next step it uses the partial tree arrangement approach which is based on tree matching, it means arranging those data field in a couple of data records that can be arranged and these independent to other data field. Jiying Wang, Fred H. Lochovsky [8], it describes the system which rebuilds the section of invisible back end database. It sends a query by using HTML form, and generates the regular expression wrappers that mine the data from query page and put the retrieved data in a structured format i.e.…”

“…There are several previous work on extracting instances and their labels from data pages [1,23]. A fundamental difference between these work and ours is that we utilize existing knowledge in the growing ontology to effectively identify data regions and occurrences of instances and labels on the data pages.…”

Abstract. The vision of Semantic Web services promises a network of interoperable Web services over different sources. A major challenge to the realization of this vision is the lack of automated means of acquiring domain ontologies necessary for marking up the Web services. In this paper, we propose the DeepMiner system which learns domain ontologies from the source Web sites. Given a set of sources in a domain of interest, DeepMiner first learns a base ontology from their query interfaces. It then grows the current ontology by probing the sources and discovering additional concepts and instances from the data pages retrieved from the sources. We have evaluated DeepMiner in several real-world domains. Preliminary results indicate that DeepMiner discovers concepts and instances with high accuracy.

Abstract. Most of Web sites are built as a matter of priority. Therefore, to reduce the development time, the conceptualization phase is often put aside and the associated documentation is neglected. Moreover, during the exploitation phase, Web sites suffer the effects of a rapid and unstructured evolution process. Their reconstruction encompasses inevitably a reverse engineering process. In this paper, we propose RetroWeb, a reverse engineering approach of semi-structured Web sites. It aims to provide a description of the site informative content at the physical, logical and conceptual levels. This approach uses, at each level, a meta-model which is instantiated using reverse engineering rules.
