METHODS AND SYSTEMS FOR DETECTING CHECK WORTHY CLAIMS FOR FACT CHECKING
Methods and systems for automatically selecting a claim for fact checking. In a first stage, a claim can be classified as objective or subjective by an objectivity classifier. If the claim is classified as objective, then in a second stage, the claim is classified as being of public interest or not. If the claim is classified as both objective and of public interest, then the claim can be selected as worthy for fact checking. This approach reduces the workload of automated systems such as data-processing systems, which saves time in performing fact checking operations and results in greater system and network efficiencies.
1 . A method for automatically selecting a claim for fact checking, comprising:
in a first stage, classifying a claim as objective or subjective;
in a second stage, classifying said claim as being of public interest or not, if said claim was classified as objective in said first stage; and
selecting said claim for fact checking if said claim is classified as both objective in said first stage and of public interest in said second stage.
2 . The method of claim 1 wherein said claim is classified as objective or subjective utilizing an objectivity classifier.
3 . The method of claim 2 wherein said objectivity classifier comprises an explicit feature driven objectivity classifier.
4 . The method of claim 2 wherein said objectivity classifier comprises an implicit objectivity classifier.
5 . The method of claim 2 wherein said objectivity classifier comprises an embedding layer, an encoder and a multilayer perceptron classifier.
6 . The method of claim 1 further comprising curating a data set composed of said claim among a plurality of claims from multiple domains.
7 . The method of claim 1 wherein said claim is classified as being of public interest or not via a public interestedness classifier comprising an explicit feature driven public interestedness classifier.
8 . The method of claim 1 further comprising expressing said claim as a textual representation.
9 . The method of claim 1 wherein said claim is classified as being of public interest or not via a public interestedness classifier comprising an implicit featureless classifier using a neural sentence representation.
10 . A system for automatically selecting a claim for fact checking, comprising: one or more computers with executable instructions that when executed cause the system to:
in a first stage, classify a claim as objective or subjective;
in a second stage, classify said claim as being of public interest or not, if said claim was classified as objective in said first stage; and
select said claim for fact checking if said claim is classified as both objective in said first stage and of public interest in said second stage.
11 . The system of claim 10 wherein said claim is classified as objective or subjective utilizing an objectivity classifier.
12 . The system of claim 11 wherein said objectivity classifier comprises at least one of: an explicit feature driven objectivity classifier and an implicit objectivity classifier.
13 . The system of claim 11 wherein said objectivity classifier comprises an embedding layer, an encoder and a multilayer perceptron classifier.
14 . The system of claim 10 wherein said executable instructions further: curate a data set composed of said claim among a plurality of claims from multiple domains.
15 . The system of claim 10 wherein said claim is classified as being of public interest or not via a public interestedness classifier comprising an explicit feature driven public interestedness classifier.
16 . The system of claim 10 wherein said executable instructions further: express said claim as a textual representation.
17 . The system of claim 10 wherein said claim is classified as being of public interest or not via a public interestedness classifier comprising an implicit featureless classifier using a neural sentence representation.
18 . A computer program product for automatically selecting a claim for fact checking by a processor, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:
an executable portion that in a first stage, classifies a claim as objective or subjective;
an executable portion that in a second stage, classifies said claim as being of public interest or not, if said claim was classified as objective in said first stage; and
an executable portion that selects said claim for fact checking if said claim is classified as both objective in said first stage and of public interest in said second stage.
19 . The computer program product of claim 18 wherein said claim is classified as objective or subjective utilizing an objectivity classifier comprising at least one of: an explicit feature driven objectivity classifier and an implicit objectivity classifier.
20 . The computer program product of claim 18 wherein said objectivity classifier comprises an embedding layer, an encoder and a multilayer perceptron classifier.
