Also the ECDC definition is supposed to be used by a doctor, while such a person normally is not involved in the formulation of the web queries.
The objective of this component is, given the free text formulation of the user's query, to extract the "important" parts, using n-grams [ 28], that refer to or designate known ontology terms, in order to get matched to the patterns that form the physicians' necessities.
The correct formulation of query plays the crucial role in the outcome of database screening and requires small additional study.
We now turn the discussion to the description of the proposed GUI, which extends the traditional input box of large-scale web search engines by (a) suggesting context-aware formulations of the intended queries based on the first letters that are inserted into the input box, and (b) visualizing the semantics of the initial query.
We consider a number of different approaches for the formulation of ranked queries for searching in the context of systematic reviews.
We are working on a graphical query builder, which will allow the formulation of queries by visually inspecting the classes and relations in the ontology schema.
In the paper, we introduce an evaluation methodology based on the 2011 QALD workshop queries that allows to measure the accuracy of a semantic search system as well as the complexity of the query formulation process.
Methods to facilitate the formulation of precise queries, using more relevant terms, should be the focus of education and research.
Amphion accepts user queries formulated with the help of a graphical query-formulation guide, producing a diagrammatic representation of the query.
