advances and professional competition have contributed to the large volume of scientific articles, making it impossible for researchers to keep up with the literature. This information overload also exists in the biomedical field, where scientific publications and other forms of text-based data are produced at an unprecedented rate due to growing research activities in the recent past. The number of text documents disseminating knowledge in this area has gone up manifolds. Most scientific knowledge is registered in publications and other unstructured representations that make it difficult to use and to integrate the information with other sources (e.g., biological databases).
