Natural language processing for mapping dependency data and parts-of-speech to group labels

A system comprising:

• one or more computers;
• and
• one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• receiving, by a computing device, data representing an unstructured sentence that includes a plurality of words;
• generating, by the computing device, a dependency parse of the unstructured sentence by assigning, to each word of the plurality of words, a dependency relationship label that identifies a relationship between the word and another word of the plurality of words;
• determining, by the computing device and for one or more of the dependency relationship labels, a mapped dependency relationship label based on the dependency relationship label;
• determining, by the computing device and for each word of the plurality of words, a part-of-speech label that identifies a part of speech for the word;
• determining, by the computing device and for each part-of-speech label, a mapped part-of-speech label based on the part-of-speech label;
• and
• selecting, by the computing device and for two or more words of the plurality of words using the respective dependency relationship labels and the respective mapped part-of-speech labels, the mapped dependency relationship label and the mapped part-of-speech label of one of the two or more words to represent the two or more words as a group dependency relationship label and a group part-of-speech label.

A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:

• receiving, by a computing device, data representing an unstructured sentence that includes a plurality of words;
• generating, by the computing device, a dependency parse of the unstructured sentence by assigning, to each word of the plurality of words, a dependency relationship label that identifies a relationship between the word and another word of the plurality of words;
• determining, by the computing device and for one or more of the dependency relationship labels, a mapped dependency relationship label based on the dependency relationship label;
• determining, by the computing device and for each word of the plurality of words, a part-of-speech label that identifies a part of speech for the word;
• determining, by the computing device and for each part-of-speech label, a mapped part-of-speech label based on the part-of-speech label;
• and
• selecting, by the computing device and for two or more words of the plurality of words using the respective dependency relationship labels and the respective mapped part-of-speech labels, the mapped dependency relationship label and the mapped part-of-speech label of one of the two or more words to represent the two or more words as a group dependency relationship label and a group part-of-speech label.
