Location aware shopping list

A method comprising:

• receiving, by one or more processors, a shopping list, wherein the shopping list includes one or more shopping list items, wherein the shopping list includes a refined shopping list entry based on a first user preference, and wherein the first user preference is determined by performing sentiment analysis on a source document;
• determining, by one or more processors, whether a shopping list item of the one or more shopping list of items is a high-level, result-based item by semantic analysis;
• responsive to determining the item of the shopping list of items is a high-level, result-based item, determining, by one or more processors, one or more component items of the high-level, result-based item using expertise sources;
• classifying, by one or more processors, each shopping list item of the one or more shopping list items into one or more hierarchies, wherein the classification is done using a predetermined taxonomy classification, wherein the classification includes a confidence level associated with each hierarchy of the one or more hierarchies;
• determining, by one or more processors, whether the confidence level associated with any hierarchy of the one or more hierarchies exceeds a predetermined threshold level;
• receiving, by one or more processors, a user preference for a shopping list item of the one or more shopping list of items;
• determining, by one or more processors, one or more refined items based on the user preference;
• determining, by one or more processors, one or more items, wherein the one or more items includes the one or more refined items in the one or more hierarchies with the confidence level that exceeds the predetermined threshold level and all of the shopping list items in the one or more hierarchies with the confidence level that exceeds the predetermined threshold level;
• determining, by one or more processors, an entity information for each shopping list item of the one or more shopping list items;
• determining, by one or more processors, one or more entity items based on the entity information;
• determining, by one or more processors, one or more items, wherein the one or more items includes the one or more entity items in the one or more hierarchies with the confidence level that exceeds the predetermined threshold level and all of the shopping list items in the one or more hierarchies with the confidence level that exceeds the predetermined threshold level;
• determining, by one or more processors, a user location, wherein the user location is periodically determined by a location-based service;
• determining, by one or more processors, a nearby store, wherein the nearby store is within a predefined driving distance of the user location;
• determining, by one or more processors, a hierarchy of categories related to a list of products offered for sale at the nearby store;
• determining, by one or more processors, a store inventory and a store location;
• determining, by one or more processors, one or more superior categories of the one or more hierarchies;
• determining, by one or more processors, a store category corresponding to one or more superior categories;
• determining, by one or more processors, whether the hierarchy of categories related to a list of products offered for sale at the nearby store matches the store category;
• determining, by one or more processors, one or more inferior categories of the one or more hierarchies;
• determining, by one or more processors, an item category corresponding to the one or more inferior categories;
• determining, by one or more processors, whether the hierarchy of categories related to a list of products offered for sale at the nearby store matches the item category;
• responsive to determining the store matches the item category, determining, by one or more processors, whether the store inventory includes any of the one or more items;
• responsive to determining the store matches the store category, determining, by one or more processors, whether the store inventory includes any of the one or more items;
• responsive to determining the store inventory includes an item of the one or more items, sending, by one or more processors, a notification to the user, wherein the notification includes an identification of the nearby store, the store location, and the item at the nearby store, wherein the identification of the nearby store and the item at the nearby store includes an aisle number where the item is located;
• receiving, by one or more processors, feedback from the user, wherein the feedback is related to the one or more hierarchies;
• and
• updating, by one or more processors, the confidence level associated with each hierarchy of the one or more hierarchies.
