Filtering search results using word clouds

Abstract

Various methods and systems are provided for implementing a search engine that generates search results for a natural language description of music. A music description and categorization schema is defined to provide a common terminology and taxonomy. Music catalogs are ingested to generate a searchable catalog index. A natural language description of music is analyzed using various natural language processing techniques to generate corresponding musical features of the schema to be searched. A query string is generated from the musical features using a query term profile including one or more query term generators. A ranking score and other search result statistics are generated. Various visualizations can be provided, including a visualization of the translated search and a visualization of search results. In some embodiments, word clouds are provided to allow a user to filter search results by a selected matched feature. As such, users can efficiently review search results.

What is claimed is: 
     
         1 . A computerized method comprising:
 causing a user interface to present a word cloud of features that were extracted from a natural language description and that matched search results of the natural language description;   generating, based on an input identifying a selected feature of the features from the word cloud, filtered search results that match the selected feature; and   causing the user interface to present a representation of the filtered search results that match the selected feature from the word cloud.   
     
     
         2 . The computerized method of  claim 1 , wherein the features are musical features of a music description and categorization schema, the natural language description is of music, and the search results are songs. 
     
     
         3 . The computerized method of  claim 1 , wherein the word cloud represents each feature of the features as a corresponding word or phrase having a size that corresponds at least in part to a count of the search results that matched the feature. 
     
     
         4 . The computerized method of  claim 1 , further comprising extracting the features by extracting chunks of text from the natural language description and translating the chunks of text into corresponding features of a description and categorization schema. 
     
     
         5 . The computerized method of  claim 1 , wherein the features represented in the word cloud are instances of core schema categories that were extracted from the natural language description and that matched the search results. 
     
     
         6 . The computerized method of  claim 1 , wherein the features represented in the word cloud are genres that were extracted from the natural language description and that matched the search results. 
     
     
         7 . The computerized method of  claim 1 , wherein the features represented in the word cloud are related artists that were extracted from the natural language description and that matched the search results. 
     
     
         8 . One or more computer storage media storing computer-useable instructions that, when executed by one or more computing devices, cause the one or more computing devices to perform operations comprising:
 causing a user interface to present a word cloud of features that were extracted from a natural language description and that matched search results of the natural language description;   generating, based on an input identifying a selected feature of the features from the word cloud, filtered search results that match the selected feature; and   causing the user interface to present a representation of the filtered search results that match the selected feature from the word cloud.   
     
     
         9 . The one or more computer storage media of  claim 8 , wherein the features are musical features of a music description and categorization schema, the natural language description is of music, and the search results are songs. 
     
     
         10 . The one or more computer storage media of  claim 8 , wherein the word cloud represents each feature of the features as a corresponding word or phrase having a size that corresponds at least in part to a count of the search results that matched the feature. 
     
     
         11 . The one or more computer storage media of  claim 8 , the operations further comprising extracting the features by extracting chunks of text from the natural language description and translating the chunks of text into corresponding features of a description and categorization schema. 
     
     
         12 . The one or more computer storage media of  claim 8 , wherein the features represented in the word cloud are instances of core schema categories that were extracted from the natural language description and that matched the search results. 
     
     
         13 . The one or more computer storage media of  claim 8 , wherein the features represented in the word cloud are genres that were extracted from the natural language description and that matched the search results. 
     
     
         14 . The one or more computer storage media of  claim 8 , wherein the features represented in the word cloud are related artists that were extracted from the natural language description and that matched the search results. 
     
     
         15 . A computer system comprising:
 one or more hardware processors and memory storing computer-useable instructions that, when executed by the one or more hardware processors, cause the one or more hardware processors to perform operations comprising:
 causing a user interface to present a word cloud of features that were extracted from a natural language description and that matched search results of the natural language description; 
 generating, based on an input identifying a selected feature of the features from the word cloud, filtered search results that match the selected feature; and 
 causing the user interface to present a representation of the filtered search results that match the selected feature from the word cloud. 
   
     
     
         16 . The computer system of  claim 15 , wherein the features are musical features of a music description and categorization schema, the natural language description is of music, and the search results are songs. 
     
     
         17 . The computer system of  claim 15 , wherein the word cloud represents each feature of the features as a corresponding word or phrase having a size that corresponds at least in part to a count of the search results that matched the feature. 
     
     
         18 . The computer system of  claim 15 , the operations further comprising extracting the features by extracting chunks of text from the natural language description and translating the chunks of text into corresponding features of a description and categorization schema. 
     
     
         19 . The computer system of  claim 15 , wherein the features represented in the word cloud are instances of core schema categories that were extracted from the natural language description and that matched the search results. 
     
     
         20 . The computer system of  claim 15 , wherein the features represented in the word cloud are genres that were extracted from the natural language description and that matched the search results.
