Abstract: An input text string may be received in a text box that is included on a web page. In response to receiving the input text string, one or more target text strings corresponding to the input text string may be identified. One or more representations of one or more syntactic entities corresponding to the one or more target strings may be identified. The one or more representations, which may be selectable when displayed, may be caused to be displayed on a display. An indication of a selected representation, which may be one of the one or more representations, may be received. In response to receiving the indication of the selected representation, a syntactic entity may be caused to be displayed in the text box in place of the input text string. The syntactic entity may correspond to a syntactic entity represented by the selected representation.
