Abstract: Systems and methods are disclosed herein for processing a natural language query on data tables. According to some embodiments, a query term is obtained from a natural language query. A table summary is prepared based on the query term and a formula of the natural language query is generated based on the table summary. A result is generated based on the formula. Responsive to receiving negative feedback to the result, one or more of the table summary or the formula is disassociated from the query term.

Abstract: Systems and methods are disclosed herein for processing a natural language query on data tables. According to some embodiments, a natural language query may be originated by a user via a user interface. The natural language query may be parsed to obtain a query term, and a grid range may be identified in a data table as relevant to the query term. A table summary may be prepared including a plurality of characteristics based on the grid range. A logic operation may then be determined to apply on the plurality of characteristics to derive the query term. The logic operation may then be translated into a formula executable on the data table, and the formula is applied on the data table to generate a result in response to the natural language query.

Abstract: In one embodiment, a method includes receiving a search query input comprising a character string having a first number of characters; searching one or more indexes of one or more verticals to identify terms corresponding to the search query input, wherein if the first number is less than or equal to a threshold number, then searching one or more first indexes, wherein each first index is related to objects of a first object-type, and if the first number is greater than the threshold number, then searching the one or more first indexes and one or more second indexes, wherein each second index is related to objects of a second object-type different than the first object-type; and sending instructions for presenting one or more suggested queries, each suggested query comprising the character string of the search query input and one or more of the identified terms.

Abstract: In one embodiment, a method includes receiving a plurality of search results based on a search query from a user. A computing system determines a plurality of scores for each search result, each score generated by applying a distinct scoring function of a plurality of scoring functions to the search result. The computing system generates a plurality of diversity groups, each diversity group corresponding to a scoring function of the plurality of scoring functions, each diversity group including at least a subset of the plurality of search results ordered according to the scores generated by applying the scoring function to the at least the subset of the plurality of search results. The method further includes selecting at least one of the plurality of search results from each diversity group and sending the selected search results to the user.
