System and method for processing cross-lingual search queries

A method being implemented via execution of computing instructions configured to run at one or more processors and stored at one or more non-transitory computer-readable media, the method comprising:

• determining, via a translatability classifier module, a translatability class label for a cross-lingual search query received, via a computer network, from a user device for a user, comprising:
• determining whether a first class-translation pair for the cross-lingual search query exists in the one or more non-transitory computer-readable media;
• when the first class-translation pair exists in the one or more non-transitory computer-readable media, retrieving the first class-translation pair for the cross-lingual search query from the one or more non-transitory computer-readable media;
• and
• when the first class-translation pair does not exist in the one or more non-transitory computer-readable media, determining whether the cross-lingual search query is ambiguous by analyzing historical session data of the cross-lingual search query to detect:
• a difference between (a) a first category sector of an archived cross-lingual search query in a first language and (b) a second category sector of the archived cross-lingual search query in a second language, wherein the archived cross-lingual search query in the second language comprises a translation of the archived cross-lingual search query in the first language;
• and
• a rapid correction instance in a user session of the historical session data, wherein detecting the rapid correction instance comprises detecting that, during the user session, the user did not engage a first set of historical search results associated with the first language, wherein the translatability classifier module is trained to determine the translatability class label among multiple translatability class labels associated with user intentions for the cross-lingual search query, wherein the user intentions comprise a desired translation for the cross-lingual search query or no translation of the cross-lingual search query, wherein the multiple translatability class labels include a first label and a second label, wherein the first label is associated with a first probability of the desired translation for the cross-lingual search query that is greater than a second probability, of the desired translation for the cross-lingual search query, associated with the second label, wherein the translatability class label is the first label or the second label, and wherein the user intentions are determined based at least in part on user interaction rates for the cross-lingual search query;
• when the cross-lingual search query is not determined to be ambiguous, determining, via a language translator module, a class-associated search query for the cross-lingual search query based on the translatability class label, as determined, for the cross-lingual search query;
• and
• transmitting, via the computer network, the class-associated search query to a monolingual search engine.

A non-transitory computer readable storage medium storing one or more computing instructions that, when run on one or more processors, cause the one or more processors to:

• determine that an input search query received, via a computer network and from a user device of a user, is a cross-lingual search query;
• determine, based on determining that the input search query is the cross-lingual search query, that a first class-translation pair for the cross-lingual search query does not exist in storage;
• determine, after determining that the first class-translation pair, for the cross-lingual search query, does not exist in the storage, a user intention of the cross-lingual search query based on interaction rates for the cross-lingual search query and a user intention of a translated search query, for the cross-lingual search query, based on interaction rates for the translated search query,
• wherein the user intention for the cross-lingual search query indicates whether a translation for the cross-lingual search query is desired;
• determine an ambiguity type for the cross-lingual search query based on a difference between the user intention for the cross-lingual search query and the user intention for the translated search query,
• wherein the ambiguity type is one of:
• a cross-language ambiguity when a same term, of the input search query, has different meanings in a primary language and a second language, or
• a second-language-variety ambiguity when one or more of the second language includes multiple second language varieties or the same term is translatable into different terms;
• determine, via a translatability classifier module, a translatability class label, among multiple translatability class labels, for the cross-lingual search query, wherein the multiple translatability class labels include a first label and a second label, wherein the first label is associated with a first probability of a desired translation for the cross-lingual search query that is greater than a second probability, of the desired translation for the cross-lingual search query, associated with the second label, and wherein the translatability class label is the first label or the second label;
• determine, via a language translator module, a class-associated search query for the cross-lingual search query based on the translatability class label, as determined, for the cross-lingual search query;
• and
• transmit, via the computer network, the class-associated search query to a monolingual search engine.
