Text conceptualization and network representation fused opinion retrieval system and method

The invention relates to a text conceptualization and network representation fused opinion retrieval system and method. The system comprises a text conceptualization module, a network representation module, an opinion retrieval score calculation module, a relevant retrieval unifying module and a sorting learning retrieval module. The text conceptualization module is used for judging concepts, in specific contexts, of entities corresponding to multiple concepts; the network representation module projects vocabulary nodes into a low-dimension semantic space; the opinion retrieval score calculation module calculates query and text topic similarity scores and to-be-queried text opinion scores to obtain text composite scores; the relevant retrieval unifying module obtains a query opinion retrieval result according to a descending order of the text composite scores and outputs the query opinion retrieval result; the sorting learning retrieval module integrates text conceptualization characteristics, network represe
