At sentence level, an approximate grammar is used to conflate syntactic and morphosyntactic variants of a given multi-word term into a common base form. ...
At word level, productive derivational morphology is used to conflate semantically related words. ...

In this paper we study the performance of linguisticallymotivated conflation techniques for Information Retrieval in Spanish. ...
In particular, we have studied the application of productive derivational morphology for single word term conflation and the extraction of syntactic dependency pairs for multi-word term conflation. ...
Firstly, we identify relations between pairs of content words inside the multi-word term, to conflate it into syntactic dependency-pairs. ...

For this purpose, we will extract the pairs of words related through syntactic dependencies in order to use them as complex index terms. ...
This process is performed in two steps: firstly, the text is parsed by means of a shallow parser and, secondly, the syntactic dependencies are extracted and conflated into index terms. ...
The authors also would like to thank Darrin Dimmick, from NIST, for giving us the opportunity to use the ZPrise system, and Fernando Martínez, from Universidad de Jaén, for helping us to make it operative ...
