Abstract: Transcription factors (TFs) are key activators of transcriptional regulation of all genes in gene transcriptional regulatory networks. Extracting a large volume of the existing knowledge about TF-TF relations from the biomedical literature is not well developed. In this thesis, we present a system called Dragon TF Relation Extractor (DTFRE), for extracting TF-TF relations from biomedical texts. This system is based on one of the largest TF-TF relation databases to date, called TFRD. DTFRE ( is the first public system that can extract relations between TFs from PubMed abstracts submitted by users. The system performance achieves an overall precision of 93% and recall 82% for a selected group of relation expressions. This technology can efficiently support biologists and medical scientists to infer function of genes, paving way for a more focused and detailed follow-up research.
