Abstract

The subject disclosure generally describes a technology by which text and/or speech descriptions are collected by showing a stimulus such as video clips to contributors (e.g., of a crowd-sourcing service). The descriptions, which are in the language of each contributor'"'"'s choice, are of the same stimulus and thus associated with one another. While each contributor may be monolingual, the technique allows for the collection of approximately bilingual data, since more than one language may be represented among the different contributors. The descriptions may be used as translation data for training a machine translation engine, and as paraphrase data (grouped by the same language) for training a machine paraphrasing system. Also described is evaluating the quality of a machine paraphrasing system via a distinctiveness metric.

Claims

1. In a computing environment, a method performed at least in part on at least one processor, comprising, presenting a stimulus to contributors, collecting a linguistic description from each responding contributor as to what the stimulus represented to the contributor, and maintaining at least some of the linguistic descriptions corresponding to that stimulus in association with one another as translation data for use in training a translation engine, or as paraphrase data for use in training a paraphrasing system, or both as translation data for use in training a translation engine, and as paraphrase data for use in training a paraphrasing system.

2. The method of claim 1 wherein collecting the linguistic description comprises receiving text data.

3. The method of claim 1 wherein collecting the linguistic description comprises receiving speech data.

4. The method of claim 1 wherein maintaining the linguistic descriptions in association with one another comprises pairing at least one of the linguistic descriptions in one language with at least one of the linguistic descriptions in another language.

5. The method of claim 1 wherein maintaining the linguistic descriptions in association with one another comprises pairing at least one of the linguistic descriptions in one language with at least one of the linguistic descriptions in another language, and further comprising, using the pairing to provide training data for training a machine translation system.

6. The method of claim 1 wherein maintaining the linguistic descriptions in association with one another comprises maintaining paraphrase data comprising descriptions in one language.

7. The method of claim 6 further comprising, using the paraphrase data to provide training data for training a machine paraphrasing system.

8. The method of claim 7 further comprising, evaluating quality of the machine paraphrasing system by measuring distinctiveness of an original sentence or phrase with a machine-generated paraphrased sentence or phrase.

9. The method of claim 8 wherein evaluating the quality further comprises, applying a metric to measure how well the machine-generated paraphrased sentence or phrase retains the original sentence'"'"'s or phrase'"'"'s meaning.

10. The method of claim 1 wherein presenting the stimulus comprises outputting video from an online video streaming site.

11. The method of claim 1 wherein collecting the linguistic description from each responding contributor comprises collecting the linguistic descriptions via a crowd-sourcing service.

12. The method of claim 1 further comprising, having the stimulus selected via a crowd-sourcing service.

13. The method of claim 1 further comprising, pre-processing the descriptions into training data for training a machine translation system or a machine paraphrasing system, or both for training a machine translation system and for training a machine paraphrasing system.

14. One or more computer-readable media having computer-executable instructions, which when executed perform steps of a process, comprising:

inputting input data corresponding to a set of words to a machine paraphrase system;

receiving output data from the machine paraphrase system corresponding to a paraphrase of the input data; and

evaluating quality of the machine paraphrase system, including obtaining a first score representing how well the output data retained the input data'"'"'s original meaning, and a second score representing how distinct the output data is from the input data.

15. The computer-readable media of claim 14 wherein obtaining the second score comprises computing a dissimilarity score based on n-gram differences between the input data and the output data.

16. The computer-readable media of claim 14 having further computer-executable instructions comprising, selecting a paraphrase based upon the first and second scores, including choosing a paraphrase that is most distinct from the input data based on the second score and that retains the input data'"'"'s original meaning within a range determined by the first score.

17. A system comprising, a source that provides a stimulus to contributors, a data collection mechanism configured to collect a linguistic description of that stimulus from each contributor, the data collection mechanism further configured to maintain translation data that associates linguistic descriptions of that stimulus that are in different languages with one another, and to maintain paraphrase data which, for at least one language, associates linguistic descriptions of that stimulus in that same language with one another.

18. The system of claim 17 further comprising, a training mechanism configured to access the translation data to train a machine translator.

19. The system of claim 17 further comprising, a training mechanism configured to access the paraphrase data to train a machine paraphrasing system.

20. The system of claim 19 further comprising a paraphrase quality measurement mechanism configured to perform a quality evaluation of the machine paraphrasing system, including via a distinctness metric of the paraphrase quality measurement mechanism.
