This paper gives an overview of the INEX 2008 Ad Hoc Track. The main goals of the Ad Hoc Track were twofold. The first goal was to investigate the value of the internal document structure (as provided by the XML markup) for retrieving relevant information. This is a continuation of INEX 2007 and, for this reason, the retrieval results are liberalized to(More)
Two studies are presented that examine disclosure of sensitive information and personali-zation in Internet-based surveys. In the first study, the impact of a personalized salutation on two forms of non-disclosure to a sensitive personal question (salary level) is tested. The results revealed that a personalized salutation tends to increase levels of active(More)
XML information retrieval (XML-IR) systems aim to better fulfil us-ers' information needs than traditional IR systems by returning results lower than the document level. In order to use XML-IR systems users must encapsulate their structural and content information needs in a structured query. Historically , these structured queries have been formatted using(More)
With XML information retrieval, like in traditional IR, the user's information need is loosely defined, linguistic variations are frequent, and answers are a ranked list of relevant elements. Like in database querying, structure is of importance and a simple list of keywords may not be sufficient to define an XML query. Structured query languages for XML(More)
XML information retrieval (XML-IR) systems differ from traditional information retrieval systems by using structure of XML documents to retrieve more specific units of information than the documents themselves. Users interact with XML-IR systems via structured queries that express their content and structural requirements. Historically, it has been common(More)
It is assumed that by focusing on retrieval at a granularity lower than documents that XML-IR systems will better satisfy users' information need than traditional IR systems. Participates in INEX's Ad-hoc track develop XML-IR systems based upon this assumption, using an evaluation methodology in the tradition of Cranfield. However, since the inception of(More)
XML information retrieval (XML-IR) systems aim to provide users with highly exhaustive and highly specific results. To interact with XML-IR systems users must express both their content and structural needs in the form of a structured query. Historically, these structured queries have been formatted using formal languages such as XPath or NEXI.(More)
