Method and system for processing a voice-based user-input

A server for processing a search query, the server comprising:

• a network communication interface for a two-way communication over a communication network;
• a processor coupled to the network communication interface, the processor being configured to:
• receive, via the network communication interface from an electronic device associated with the user, a first voice command from the user, the first voice command comprising an indication of a first search query;
• receive, via the network communication interface from the electronic device associated with the user, a second voice command from the user, the second voice command comprising an indication of a second search query;
• determine if the second search query is a refinement of the first search query by executing the steps of:
• performing a first pseudo search based on a combination of the first search query and the second search query;
• performing a second pseudo search including the second search query alone;
• determining relative weight of the first pseudo search results and the second pseudo search results;
• deducing that:
• (i) the second search query is a refinement of the first search query responsive to the relative weight of the first pseudo search results being higher than that of the second pseudo search results;
• (ii) the second search query is a brand new query independent of the first search query responsive to the relative weight of the first pseudo search results being lower than that of the second pseudo search results.

A non-transient computer readable medium comprising computer executable instructions, which instructions when executed are configured to cause a processor of a server to execute:

• receiving, via a communication network from an electronic device associated with the user, a first voice command from the user, the first voice command comprising an indication of a first search query;
• receiving, via the communication network from the electronic device associated with the user, a second voice command from the user, the second voice command comprising an indication of a second search query;
• determining if the second search query is a refinement of the first search query, said determining comprising:
• performing a first pseudo search based on a combination of the first search query and the second search query;
• performing a second pseudo search including the second search query alone;
• determining relative weight of the first pseudo search results and the second pseudo search results;
• deducing that:
• (i) the second search query is a refinement of the first search query responsive to the relative weight of the first pseudo search results being higher than that of the second pseudo search results;
• (ii) the second search query is a brand new query independent of the first search query responsive to the relative weight of the first pseudo search results being lower than that of the second pseudo search results.
