“…Perhaps for these reasons, although there are many IRS able to deal with XML documents 5 , often these systems can only process CO queries. Nevertheless, a general method used to convert some of these only CO-able systems into a fully structured IRS, which can process CAS queries, has recently been proposed by de Campos et al [8]. This may be useful in our case because some of the proposed personalization strategies internally transform the original CO queries submitted by the users into CAS queries.…”

“…Each about clause contains both a set of terms and a relative path from the structural unit which is the container of the clause, to the structural unit contained in it where these terms should be located. NEXI is both a simplified XPath containing only the descendant operator in a tag path and an extended XPath containing the about clause 8 . For example, the following CAS query attempts to retrieve chapters dealing with personalization and containing a bibliography of INEX, within books with a title related to information retrieval: In this case, the chapter units are the target and the 8.…”

“…This modification of the retrieval model can be used together with the normalized query expansion strategy, and also with reranking; within the CAS queries approach it makes no sense because the original and profile terms are not used together, they are used separately in the target and 8 context subqueries of the complete CAS query.…”

Abstract-As the amount of information increases every day and the users normally formulate short and ambiguous queries, personalized search techniques are becoming almost a must. Using the information about the user stored in a user profile, these techniques retrieve results that are closer to the user preferences. On the other hand, the information is being stored more and more in an semi-structured way, and XML has emerged as a standard for representing and exchanging this type of data. XML search allows a higher retrieval effectiveness, due to its ability to retrieve and to show the user specific parts of the documents instead of the full document. In this paper we propose several personalization techniques in the context of XML retrieval. We try to combine the different approaches where personalization may be applied: query reformulation, reranking of results and retrieval model modification. The experimental results obtained from a user study using a parliamentary document collection support the validity of our approach.

“…de Campos et al (2010) provide a good example of XML being used both as a mark-up language for the augmentation of document functionality, but also as a technological framework for the development of services to augment 'frequent user requests' by way of the XML path language. They set out a general methodology to enable an Information Retrieval (IR) system to process structured queries.…”
