Question Answering for Alzheimer Disease Using Information Retrieval

Sanmitra Bhattacharya, Luca Toldo
2012 Conference and Labs of the Evaluation Forum  
The "Machine Reading of Biomedical Texts about Alzheimer Disease" task of CLEF QA4MRE encouraged the development of systems that can automatically find answers to questions on Alzheimer disease.  ...  With the tremendous growth of biomedical literature and data, it's no longer feasible for researchers to manually sift through this information for answering questions on specific topics.  ...  Conclusion In this paper we proposed various strategies for automated question answering for Alzheimer disease. We selected an information retrieval based approach for this purpose.  ...
