Abstract

A computer-implemented method for checking a search query used for retrieving information from a collection of records in an event sequence analysis system is disclosed. The method includes receivinga search query including a plurality of predicates and one or more constraints each associated with plural predicates, in which each predicate is specified to be positive or negative, and the plurality of the predicates forms a logical graph together with the one or more constraints. The method also includes generating from the graph a subgraph including one or more predicates specified to be positive among the plurality of the predicates. The method further includes determining whether the subgraph has plural components or not, and invalidating the search query in response to the subgraph being determined to have plural components.

Description

Background technique [0001] The present disclosure relates generally to data analysis, and more specifically, to techniques for examining search queries for retrieving information from a collection of records in a data analysis system. [0002] Due to the large volumes of data being recorded every hour of every day in various fields, considerable efforts have been made to develop techniques to extract meaningful information from collections of records. Event sequence analysis is a technique for retrieving meaningful patterns from event sequence data. Examples of such sequence of events data may include clinical data in a hospital, message data in a social networking service, and the like. [0003] A search query used in event sequence analysis can consist of one or more predicates, each used to retrieve a list of key-value pairs, and constraints between two predicates, each used to retrieve Extract pairs of elements that have some temporal relationship. [0004] Due to its ...
