Daniel Ferrés and Horacio Rodríguez.
Evaluating Geographical Knowledge Re-Ranking, Linguistic Processing and Query Expansion Techniques for Geographical Information Retrieval .
Proceedings of the 22th International Symposium on String Processing and Information Retrieval (SPIRE 2015). September, 2015. London, UK. Lecture Notes in Computer Science. Vol. 9309, pages 311-323. Springer. 2015.
This paper shows the evaluation of the different components of the TALPGeoIR applied over three state-of-the-art IR algorithms: TF-IDF, BM25 and InL2. The components evalu- ated were: Geographical Knowledge-Reranking, Linguistic Processing, and Query Expansion with Relevance Feedback. The evaluation was done with the full GeoCLEF collections from 2005 to 2008 (100 topics) and showed improvement of the MAP effectiveness measure over of the best official results at GeoCLEF evaluations of 2005, 2006, and 2007.

Knowledge-Based and Data-Driven Approaches for Georeferencing of Infor- mal Documents. Proceedings of the 8th International Conference on Text, Speech and Dialogue TSD 2015. September, 2015. Plzen, Czech Republic.
Lecture Notes in Computer Science. Vol 9302. Springer. Pages 452-460.
This paper describes four Georeferencing approaches, experiments, and results at the MediaEval 2014 Placing Task (ME2014PT) evaluation, and posterior experiments. Some of the approaches achieved state-of-the-art results at ME2014PT evaluation and posterior experiments, including the best results for distance accuracies of 1000km and 5,000km in the task where only the official training dataset can be used to predict the coordinates.

Georeferencing Textual Annotations and Tagsets with Geographical Knowl- edge and Language Models
Actas de la SEPLN (Sociedad Española para el Procesamiento del Lenguaje Natural). September 2011. Huelva, Spain.
This paper proposed 4 new generic textual georeferencing approaches based on Geograph- ical Knowledge Bases, Linguistic Knowledge, and Information Retrieval.
