Computer-implemented presentation of synonyms based on syntactic dependency
In an embodiment, the disclosed technologies are capable of identifying a target word within a text sequence; displaying a subset of candidate synonyms for the target word, determining a synonym selected from the subset of candidate synonyms, and replacing the target word with the selected synonym, where the subset of candidate synonyms has been created using syntactic dependency data for the target word.
1. A computer-implemented method comprising:
in response to receiving a text sequence input of two or more words, determining and storing the text sequence and a target word of the text sequence;
inputting the text sequence including the target word into a dependency parser and outputting syntactic dependency data for the target word associated with a syntactic dependency relationship between the target word and at least one other word of the text sequence;
retrieving a target word vector indicating a semantic meaning of the target word, a set of candidate synonyms for the target word and a set of candidate word vectors indicating semantic meanings of the candidate synonyms;
inputting the syntactic dependency data into a trained neural network-based model and receiving as output a dependency context vector indicating a semantic meaning of the syntactic dependency data;
for each candidate synonym of the set of candidate synonyms using the target word vector, the candidate word vector, and the dependency context vector, computing a similarity score, wherein the similarity score indicates a semantic similarity of the candidate synonym to the target word;
when the similarity score for a candidate synonym satisfies a criterion, adding the candidate synonym to a subset of candidate synonyms; and
displaying the subset of candidate synonyms on a graphical user interface of a mobile computing device.
2. The computer-implemented method of claim 1 , further comprising:
executing the determining and storing, the inputting, and the outputting using a thesaurus subsystem hosted and executed using a server computer; and
displaying the subset of candidate synonyms using a browser of the mobile computing device.

8. The computer-implemented method of claim 4 , wherein extracting the text from a digital content item comprises extracting the text from a document, a message, a social media posting, a list of search results, or a web page.
9. The computer-implemented method of claim 1 , wherein receiving a text sequence input including a target word comprises detecting a trigger signal and switching from displaying a virtual keyboard to displaying a thesaurus interface.
10. The computer-implemented method of claim 9 , wherein the trigger signal comprises one or more of a position of a cursor relative to a word in the text sequence input and a time elapsed from a last cursor movement.
11. A mobile computing device, comprising a display, a processor coupled to the display, a memory coupled to the processor, and one or more non-transitory computer-readable media coupled to the processor and storing one or more sequences of instructions which, when executed by the processor, cause the processor to perform:
displaying, on the display, a graphical user interface that includes an input area and an output area;
receiving a text sequence input including a target word;
displaying, in the output area, a subset of candidate synonyms for the target word, the subset of candidate synonyms being created by:
inputting the text sequence including the target word into a dependency parser and outputting syntactic dependency data for the target word associated with a syntactic dependency relationship between the target word and at least one other word of the text sequence;
inputting the syntactic dependency data into a trained neural network-based model and receiving as output a dependency context vector indicating a semantic meaning of the syntactic dependency data;
retrieving a set of candidate synonyms for the target word from a search engine;
for each candidate synonym of the set of candidate synonyms, using a target word vector indicating a semantic meaning of the target word, a set of candidate word vectors indicating semantic meanings of the candidate synonyms, and the dependency context vector, computing a similarity score, wherein the similarity score indicates a semantic similarity of the candidate synonym to the target word;
when the similarity score for a candidate synonym satisfies a criterion, adding the candidate synonym to a subset of candidate synonyms.
12. The mobile computing device of claim 11 , wherein the instructions for receiving a text sequence input further comprise sequences of instructions which, when executed by the processor, cause the processor to perform:
executing the inputting, and the outputting using a thesaurus subsystem hosted and executed using a server computer;
