A Framework for Enhancing Non Context-Driven XML Search
AbstrAct: A data element specifies one of the characteristics of its parent element. Therefore, the context of a data element is determined by its parent. Non context driven search engines build relationships between data nodes based solely on their labels and proximity to one another while overlooking their contexts. Therefore, they may return faulty answers. This paper investigates the pitfal...
متن کاملSemantic Based XML Context Driven Search And Retrieval System
we present in this paper, a context-driven search engine called XCD Search for answering XML Keyword-based queries as well as Loosely Structured queries, using a stack-based sort-merge algorithm. Most current research is focused on building relationships between data elements based solely on their labels and proximity to one another, while overlooking the contexts of the elements, which may lea...
متن کاملContext-Aware Search Spaces for Queries with Spatial Relations
Web-mapping services, like Google Maps, allow natural language queries, like “Hotels Freiburg”. These queries are interpreted as “Hotels in Freiburg” or “Hotels near Freiburg”. In this thesis, we introduce the two new spatial relation “between” and the compass directions, allowing queries like “Gas stations between Freiburg and Stuttgart” or “Hotels north of Freiburg”. To achieve this, we analy...
متن کاملSpatial context and top-down strategies in visual search.
Marvin M. Chun and Yuhong Jiang (1998) investigated the role of spatial context on visual search. They used two display conditions. In the Old Display condition, the spatial arrangement of items in the search display was kept constant throughout the experiment. In the New Display condition, the spatial arrangement of items was always novel from trial to trial. The results showed better performa...
متن کاملSpatial context learning in visual search and change detection.
Humans conduct visual search more efficiently when the same display is presented for a second time, showing learning of repeated spatial contexts. In this study, we investigate spatial context learning in two tasks: visual search and change detection. In both tasks, we ask whether subjects learn to associate the target with the entire spatial layout of a repeated display (configural learning) o...
