Methods and Systems for Improved Document Processing and Information Retrieval

A method comprising:

• determining by a searching system, at a first time instance, one or more first search results for a first query comprising one or more query terms associated with a first concept;
• modifying the query, based on the determined one or more first search results, to include one or more modified query terms associated with one or more concepts hierarchically related to the first concept;
• wherein modifying the query comprises
• identifying one or more ambiguity categories associated with multiple matches from the one or more first search results, at least one of the one or more identified ambiguity categories being associated with at least some of the multiple matches and including different respective values associated with the at least some of the multiple matches,
• obtaining disambiguation information relevant to the at least one of the one or more identified ambiguity categories, and
• selecting at least one of the multiple matches based on the obtained disambiguation information relevant to the at least one of the one or more identified ambiguity categories;
• and
• determining at a subsequent time instance one or more subsequent search results for the modified query comprising the one or more modified query terms.
