20150220680 | INFERRING BIOLOGICAL PATHWAYS FROM UNSTRUCTURED TEXT ANALYSIS - A biological pathway is a series of actions that take place in an organism that lead to some resulting pathology or otherwise change the organism state. In the cell, these actions typically take place between molecules called proteins.

20150324481 | Building Entity Relationship Networks from n-ary Relative Neighborhood Trees - Entities are objects with feature values that can be thought of as vectors in N-space, where N is the number of features. Similarity between any two entities can be calculated as a distance between the two entity vectors. A similarity network can be drawn between a set of entities based on connecting two entities that are relatively near to each other in N-space. Binary relative neighborhood trees are a special type of entity relationship network, designed to be useful in visualizing the entity space. They have the intuitively simple property that the more typical entities occur at the top of the tree and the more unusual entities occur at the leaf nodes. By limiting the number of links to n+1 per node (one parent, n children), a regularized flat tree structure is created that is much easier to visualize and navigate at both a course and a fine level by domain experts. | 11-12-2015 |
20150332158 | MINING STRONG RELEVANCE BETWEEN HETEROGENEOUS ENTITIES FROM THEIR CO-OCURRENCES - Given two heterogeneous entities, the prevalence of text data provides rich co-occurrence information for them. However, the co-occurrence only is noisy—not only may the co-occurrence just imply an accidental writing, but also it may just reflect the domain-specific common words. Only those strong relevance between entities supported by rich relevance contexts in data can indicate meaningful entity relationships. Strong relevance between heterogeneous entities are mined from their co-occurrences. Drug-disease therapeutic relationships are used as the example to demonstrate an application of this work. | 11-19-2015 |
