NAME Lingua::Identify::Any - Detect language of text using one of several available backends VERSION This document describes version 0.002 of Lingua::Identify::Any (from Perl distribution Lingua-Identify-Any), released on 2019-07-12. SYNOPSIS use Lingua::Identify::Any qw( detect_text_language ); my $res = detect_text_language(text => 'Blah blah blah'); Sample result: [200, "OK", { backend => 'Lingua::Identify', lang_code => "en", confidence => 0.78, # 1 would mean certainty is_reliable => 1, }] DESCRIPTION This module offers a common interface to several language detection backends. FUNCTIONS detect_text_language Usage: detect_text_language(%args) -> [status, msg, payload, meta] Detect language of text using one of several available backends. Backends will be tried in order. When a backend is not available, or when it fails to detect the language, the next backend will be tried. Currently supported backends: * Lingua::Identify::CLD * Lingua::Identify * WebService::DetectLanguage (only when "try_remote_backends" is set to true) This function is not exported by default, but exportable. Arguments ('*' denotes required arguments): * backends => *array[str]* * dlcom_api_key => *str* API key for detectlanguage.com. Only required if you use WebService::DetectLanguage backend. * text* => *str* * try_remote_backends => *bool* Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (hash) Status: will return 200 status if detection is successful. Otherwise, will return 400 if a specified backend is unknown/unsupported, or 500 if detection has failed. Payload: a hash with the following keys: "backend" (the backend name used to produce the result), "lang_code" (str, 2-letter ISO language code), "confidence" (float), "is_reliable" (bool). ENVIRONMENT PERL_LINGUA_IDENTIFY_ANY_BACKENDS String. Comma-separated list of backends. PERL_LINGUA_IDENTIFY_ANY_TRY_REMOTE_BACKENDS Boolean. Set the default for "detect_text_language"'s "try_remote_backends" argument. If set to 1, will also include backends that query remotely, e.g. WebService::DetectLanguage. PERL_LINGUA_IDENTIFY_ANY_DLCOM_API_KEY String. Set the default for "detect_text_language"'s "dlcom_api_key". HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at .
