Abstract

Systems and methods are disclosed herein for providing search results, particularly product records from a product database. Tokens of a query are identified. Product records including one or more tokens in values associated with the attributes thereof are identified. A score is generated for attributes of products including a token (an attribute-token score). The attribute-token score is based on a frequency of occurrence of the token in the attribute value and a length of the attribute value in which it occurs. The attribute-token scores for the token are summed to generated a score. The token score for a token may be scaled in a non-linear fashion such that the scaled value approaches a saturation value, which may be an inverse document frequency (IDF) score for the token. The scaled values may then be summed to generate a score for the document that is used to rank the search results.

Dependent claims

A method for attribute-based searching, the method comprising:

receiving, by a computer system, a query;
identifying, by the computer system, tokens in the query;
identifying, by the computer system, a plurality of documents including at least one token t of the tokens in the query;
for each document d of the plurality of documents including at least one token t of the tokens in the query, calculating, by the computer system, token-attribute scores tfc(t,d) for each attribute value c of the each document d, the token-attribute scores tfc(t,d) decreasing with length of the attribute value c;
assigning, by the computer system, a document score to each document d of the plurality of documents based on a summation of the token-attribute scores tfc(t,d) for the each document d;
ranking, by the computer system, the plurality of documents according to the document scores;
and
returning, by the computer system, at least a portion of the ranked plurality of documents as a response to the query.

5 more elements

A system for attribute-based searching, the system comprising one or more processors and one or more memory devices operably coupled to the one or more processors, the memory devices storing executable and operational data effective to cause the one or more processors to:

receive a query;
identify tokens in the query;
identify a plurality of documents including at least one token t of the tokens in the query;
for each document d of the plurality of documents including at least one token t of the tokens in the query, calculate token-attribute scores tfc(t,d) for each attribute value c of the each document d, the token-attribute scores tfc(t,d) decreasing with length of the attribute value c;
assign a document score to each document d of the plurality of documents based on a summation of the token-attribute scores tfc(t,d) for the each document d;
rank the plurality of documents according to the document scores;
and
return at least a portion of the ranked plurality of documents as a response to the query.
