Biomedical Relationship Extraction from literature based on bio-semantic token subsequences

Toward Ontology-Based Knowledge Extraction from Biomedical Literature

Semantic Based Retrieval of Biomedical Literature

The published literature in bioinformatics and the biomedical field is rapidly increasing and the total citations maintained by PubMed surpass 16 million. While it is very encouraging to witness the rapid advancement of research in this important area, this enormous volume creates a problem for researchers to keep up with the current literature. Text-based search portals such as Google help to ...

Mining hidden connections among biomedical concepts from disjoint biomedical literature sets through semantic-based association rule

The novel connection between Raynaud dise ase and fish oils was uncovered from two disjointed biomedical literature sets by Swanson in 1986. Since then, there have been many approaches to uncover novel connections by mining the biomedical literature. One of the popular approaches is to adapt the Association Rule (AR) method to automatically identify implicit novel connections between concept A ...

Disease causality extraction based on lexical semantics and document-clause frequency from biomedical literature

BACKGROUND Recently, research on human disease network has succeeded and has become an aid in figuring out the relationship between various diseases. In most disease networks, however, the relationship between diseases has been simply represented as an association. This representation results in the difficulty of identifying prior diseases and their influence on posterior diseases. In this pape...

Semantic Property Grammars for Knowledge Extraction from Biomedical Text

We present Semantic Property Grammars, designed to extract concepts and relations from biomedical texts. The implementation adapts a CHRG parser we designed for Property Grammars [1], which views linguistic constraints as properties between sets of categories and solves them by constraint satisfaction, can handle incomplete or erroneous text, and extract phrases of interest selectively. We endo...
