Query: Automatic generation of semantic corpora for improving intent estimation
  of taxonomy-driven search engines   With the increasing demand of intelligent systems capable of operating in
different user contexts (e.g. users on the move) the correct interpretation of
the user-need by such systems has become crucial to give a consistent answer to
the user query. The most effective techniques which are used to address such
task are in the fields of natural language processing and semantic expansion of
terms. Such systems are aimed at estimating the actual meaning of input
queries, addressing the concepts of the words which are expressed within the
user questions. The aim of this paper is to demonstrate which semantic relation
impacts the most in semantic expansion-based retrieval systems and to identify
the best tradeoff between accuracy and noise introduction when combining such
relations. The evaluations are made building a simple natural language
processing system capable of querying any taxonomy-driven domain, making use of
the combination of different semantic expansions as knowledge resources. The
proposed evaluation employs a wide and varied taxonomy as a use-case,
exploiting its labels as basis for the expansions. To build the knowledge
resources several corpora have been produced and integrated as gazetteers into
the NLP infrastructure with the purpose of estimating the pseudo-queries
corresponding to the taxonomy labels, considered as the possible intents.
