Abstract: A method, computer system, and computer program product for measuring the similarity of clinical trials are provided. The embodiment may include receiving user-entered clinical trial data. The embodiment may also include extracting concepts and values from each section of the received clinical trial data using natural language processing. The embodiment may further include searching a corpus of existing trials with concepts similar to the extracted concepts and values. The embodiment may also include computing an edit-distance for each section of the existing trial. The embodiment may further include calculating an overall similarity score based on a weighted distance of each section of the existing trial. The embodiment may also include displaying the overall similarity score to a user on a graphical user interface.

Abstract: A method, computer system, and computer program product for measuring similarity of numeric concept values within a corpus are provided. The embodiment may include retrieving numerical values associated with a concept in a corpus. The embodiment may also include converting the numerical values to a standard unit. The embodiment may further include computing a distribution value of the converted numerical values. The embodiment may also include determining a tolerance value based on the distribution value, wherein the tolerance value is the maximum allowable distance between two numerical values. The embodiment may further include determining a distance function based on the determined tolerance value, wherein the distance function is defined by dividing a difference between two numerical values by the determined tolerance value. The embodiment may also include computing a similarity distance between the numerical values.
