Abstract: The present invention relates to processing of textual information in order to automatically answer user-submitted questions pertaining to a given knowledge domain. A proposed system (500) includes a user input interface (510) adapted to receive a user-formulated question (QU) on a natural language format. A transforming module (520), on one hand, converts the user formulated question (QU) into a question template format (QUT) including at least one entity term indicative of a respective main concept embodied in the user formulated question (QU), and on the other hand, converts the user formulated question (QU) into a data instance matching format (QUD) adapted to query a structured database (570), which represents at least a part of a conceptual model of the knowledge domain. A lexicon database (540) contains a multitude of concepts (C) which each is related to a specific question template.
