A non-transient computer readable medium comprising a plurality instructions which are configured to, when executed, decrease a number of individual entries in a database of a plurality of user created data records relating to a single consumable item by causing a computerized apparatus to:

• receive the plurality of user created data records from a plurality of user devices;
• store the plurality of user created data records in the database, each of the plurality of user created data records including at least a description string;
• place each of the plurality of user created data records into one of a plurality of groups based at least in part on the description string associated thereto such that individual ones of the plurality of user created data records having description strings which are identical are placed in a same one of said plurality of groups;
• merge at least two of the plurality of groups into a combined group via application of a comparison operation to the description strings thereof;
• and
• select one of the data record in the combined group as a reliable data record for the combined group.

A method for decreasing a number of individual entries in a database of user-created records which describe a single item, the method comprising:

• receiving a plurality of user-created records, each of said records comprising at least a descriptive string;
• placing individual ones of the plurality of user-created records having a sufficiently similar descriptive string into one of a plurality of first groups, each of the plurality of first groups having a descriptive string;
• hashing the descriptive string of each of the plurality of first groups in order to place two or more groups into a single bin;
• performing a pair-wise comparison of the descriptive strings of the two or more groups in each bin;
• and
• when the comparison of the descriptive strings of the two or more groups in a bin results in a distance below a first threshold, merging the two or more groups into a combined group.
