Abstract: A system is provided for facilitating medical conversation. The system includes a user interface, having a Natural Language Processing (NLP) system and an Automatic Speech Recognition (ASR) system, for processing user utterances to extract symptoms, attribute types and attribute values from a user. The system further includes a memory for storing program code. The system also includes a processor for running the program code to transform the symptoms, the attribute types, and the attribute values into a graph and extract relative entities and relationships of the relative entities from the graph. The processor further runs the program code to calculate an Inquiry Efficiency Index (IEI) of each candidate inquiry path based on the relative entities and the relationships of the relative entities. The processor additionally runs the program code to calculate a recommended inquiry path from among the candidate inquiry paths based on the IEI of each candidate inquiry path.

Abstract: A cognitive conversation system that generates effective diagnostic questions is provided. The cognitive conversation system receives a set of currently known symptoms (or currently available answers to diagnostic questions) of a reported problem or fault. The system identifies (i) a set of possible root causes of the reported problem based on the currently known symptoms and (ii) probabilities for the set of possible root causes by using a bipartite graph data structure that links possible symptoms with possible root causes. Upon determining that at least one possible root cause has a probability that is higher than a threshold, the system presents an explanation or solution associated with the at least one possible root cause. Upon determining that none of the possible root causes in the set of possible root causes has a probability higher than the threshold, the system presents a question based on information entropy that is computed based on probabilities of the identified possible root causes.

Abstract: A mechanism is provided for optimizing web page pre-loading. Source codes of a web page file are analyzed to generate a module dependency graph that describes load dependency relationships between respective modules in the web page file. A load flow graph that indicates load flows of respective modules in the web page file is generated based on the module dependency graph. The load flow graph and the module dependency graph are analyzed to determine pre-load sequences of respective modules in the web page file. A pre-load profile is then generated based on the determined pre-load sequences.

Abstract: Method and systems for tagging code include organizing code units in a hierarchical structure that associates the code units with respective description units. The hierarchical structure is filtered to remove un-meaningful description units from the hierarchical structure. Feature tags are generated based on a weighted sum of term frequencies in the description units of the hierarchical structure to associate features with respective code units.

Abstract: A fine-grained behavior model matching based method and system for effective feature location in large legacy systems. A feature behavior analyzer extracts internal behaviors of a feature under requesting based on NLP techniques or writing rules of the feature specification and generates a feature behavior model. A method uses multiple information sources associated with each method under analyzing to generate an expressive behavior signature for each method. The method integrates control flow information of each method and the signature information of its callees, and generates a CFG-based behavior model. A feature location identifier identifies and ranks the feature-related code locations based on a similarity between the feature behavior and the code behavior models. In one aspect, “use cases”, “source code repository” and “issue tracking system” are historical information of existing applications that are used to help understand each code unit of legacy systems applications, and recommend code units related with the given feature description.
