Search query processing system

A search system configured to perform searches in response to user queries, the system comprising:

• a network interface;
• at least one processing device operable to perform operations comprising:
• access a plurality of items of content comprising text related to one or more items;
• access helpfulness data with respect to respective items plurality of items of content and based at least in part on the accessed helpfulness data determine whether at least a portion of the items plurality of items of content are to be excluded from sentiment analysis;
• tokenize the text of at least a portion of the plurality of items of content related to one or more items, wherein certain portions of the text are split into individual words as respective tokens, and at least one multi-word expression is maintained as a single token thereby preserving its semantic meaning;
• utilize a large language model to extract metadata from at least a portion of the tokenized plurality of items of content related to one or more items, wherein a performance of the large language model is improved by training the large language model on a specific task of sentiment analysis using labeled data;
• perform sentiment analysis to determine user sentiment regarding respective item attributes and/or items;
• assign respective values to one or more of a given item's attributes based at least in part on the determined user sentiment;
• receive a handshaking message from a client on a first user device that identifies a cipher suite supported by the client and that includes a string configured to be used in generating an encryption key;
• generate a key configured to be used in encrypting messages between the system and the first user device;
• respond to the client with a handshaking signal which identifies the cipher suite suit and encryption version to be used;
• receive, via the network interface over a network from a first user device, associated with a first user, a first query;
• enhance a search functionality by:
• perform a search for items satisfying the first query using the extracted metadata;
• rank items identified in the search based at least in part on respective values, the values based at least in part on the determined user sentiment, assigned to respective attributes associated with the items;
• and
• transmit over the network, using the network interface, ranked search results, to the user device, the ranked search results corresponding at least in part to the item and/or item attribute rankings, wherein the ranked search results are displayed via the user device;
• receive a selection of a first item in the search results;
• determine a location of the first item;
• determine a first location of the first user;
• cause a first navigation route to be generated from the first location of the first user to the location of the first item;
• and
• cause the first navigation route from the first location of the first user to the location of the first item to be transmitted to and displayed by the first user device in association with a map.
