Extracting Higher Order Relations From Biomedical Text
نویسندگان
چکیده
Argumentation in a scientific article is composed of unexpressed and explicit statements of old and new knowledge combined into a logically coherent textual argument. Discourse relations, linguistic coherence relations that connect discourse segments, help to communicate an argument’s logical steps. A biomedical relation exhibits a relationship between biomedical entities. In this paper, we are primarily concerned with the extraction of connections between biomedical relations, a connection that we call a higher order relation. We combine two methods, namely biomedical relation extraction and discourse relation parsing, to extract such higher order relations from biomedical research articles. Finding and extracting these relations can assist in automatically understanding the scientific arguments expressed by the author in the text.

BRONCO: Biomedical entity Relation ONcology COrpus for extracting gene-variant-disease-drug relations
Comprehensive knowledge of genomic variants in a biological context is key for precision medicine. As next-generation sequencing technologies improve, the amount of literature containing genomic variant data, such as new functions or related phenotypes, rapidly increases. Because numerous articles are published every day, it is almost impossible to manually curate all the variant information fr...
متن کاملRobust Relational Parsing Over Biomedical Literature: Extracting Inhibit Relations
We describe the design of a robust parser for identifying and extracting biomolecular relations from the biomedical literature. Separate automata over distinct syntactic domains were developed for extraction of nominal-based relational information versus verbal-based relations. This allowed us to optimize the grammars separately for each module, regardless of any specific relation resulting in ...
متن کاملSubsequence Kernels for Relation Extraction
We present a new kernel method for extracting semantic relations between entities in natural language text, based on a generalization of subsequence kernels. This kernel uses three types of subsequence patterns that are typically employed in natural language to assert relationships between two entities. Experiments on extracting protein interactions from biomedical corpora and top-level relatio...

In this paper we propose a rule-based mechanism using Natural Language Processing techniques for extracting biological relations from biomedical text documents. While the rules identify frequently occurring patterns that can be potential relations, significant relations are identified using statistical analysis. Evaluation of the technique has been done on MEDLINE abstracts obtained from the GE...
متن کاملSimple Algorithms for Complex Relation Extraction with Applications to Biomedical IE
A complex relation is any n-ary relation in which some of the arguments may be be unspecified. We present here a simple two-stage method for extracting complex relations between named entities in text. The first stage creates a graph from pairs of entities that are likely to be related, and the second stage scores maximal cliques in that graph as potential complex relation instances. We evaluat...
