Abstract: A system and method for analysing a data set based on ranking of observations is disclosed. The method includes uploading the data set by a user and selecting one or more significant variables in the data set that interests the user and represents a priority & focus of a study. The method further includes automatically selecting an appropriate statistical technique based on the type of the variable for performing a correlation analysis for measuring an interdependence of one or more variables associated with the data set and assessing a magnitude of the relationship between the one or more variables. The method further includes performing a correlation for generating one or more correlation results. The method further includes returning a list of key analysis to the user, based on the one or more significant variables and the one or more correlation results.

Abstract: A method of information retrieval is provided. The method comprises receiving a query from a user and parsing the query in real-time as the user enters the query. The parsed query is interpreted dynamically based on a defined schema of a knowledge base, and a number of query interpretations is displayed in real-time as the user enters the query. When a selection of one of the query interpretations is received from the user information is retrieved from the knowledge base according to the selected query interpretation.

Abstract: A processor-implemented method and a system for user-selected selected joining two or more research studies to extract analytical insights for enabling cross-study analysis is disclosed. The method includes identifying, using an identification module, at least one matched variable in a statistically representative sample in each of the two or more research studies. The method further includes establishing, using a segment establishing module, for each combination of matched variables, a schema of segments, from the two or more research studies. The method furthermore includes determining, using the segment establishing module if each of the established schema of segments is statistically representative. The method furthermore includes creating a joint study, using a joint study creation module, by combining responses from each of the two or more research studies within each segment of the statistically representative schema of segments.
