Methods, systems and computer program products are provided. Terms of unsubmitted input data entered by a user during composition of submitted input data for the performance of a task are identified. For an identified unsubmitted term, a relevance score indicating the relevance of the unsubmitted term to user intent is determined. The relevance score of the unsubmitted term is determined using a graphical semantic model based on the submitted input data as a representation of user intent. The identified unsubmitted term is selected, for use in supplementing the submitted input data for the performance of the task, based on the determined relevance score.

Utilizing unsumbitted user input data for improved task performance

A processor expands a search expression. The processor determines nodes representing query terms of a search expression. The nodes have associated text for search term expansion, and represent at least one concept in a semantic graph of nodes that represents a domain of semantically related concepts. The processor determines i) a center of focus within the semantic graph for the two or more nodes based, at least in part, on a spreading activation in the graph and ii) a contextual relevance for the two or more nodes with respect to node the center of focus. The processor selects, for a query term, a node based on contextual relevance between that node and the query term and expands the search expression using an associated text of that node.
