Abstract

A system for information retrieval accessing any number of search engines over a distributed network or local network is presented. The system includes one or more pre-built ontologies or lexicons, representing areas of knowledge. The system includes a settings panel where searchers can preset default languages, default ontologies, and target search engines. The system includes an application that receives a variety of searcher input from a user interface such as a spinning wheel, or from a scrolling list. Through such selections, the application subsequently builds a Boolean search engine string of terms. The Boolean search string is then passed to the target search engine for retrieving semantically accurate search results. The Boolean search string provides a tight range on the search parameters and thereby delivers higher quality results that are more precise.

Claims

1. A computer-implemented method for performing a semantic search, the method comprising:

receiving one or more semantic identifiers that identify content that avoids at least some ambiguities inherent in keywords;

merging one or more ontologies for inclusion in the search;

receiving one or more filters that further refine the search;

selecting a target search engine to which to deliver the query;

generating a Boolean query based on the received semantic identifiers and filters;

sending the generated query to the selected search engine;

receiving query results from the search engine; and

displaying the received query results to the user so that the user can select individual results,

wherein the preceding steps are performed by at least one processor.

2. The method of claim 1 wherein receiving one or more semantic identifiers comprises displaying a list of multi-level categories to a user and receiving the user'"'"'s selection from a category at one or more levels.

3. The method of claim 1 wherein receiving one or more semantic identifiers comprises receiving keywords from the user, mapping the received keywords to possible categories, and receiving a selection from the user of one or more mapped categories to be included in the query, wherein the categories disambiguate the user'"'"'s entered keywords.

4. The method of claim 1 wherein receiving one or more semantic identifiers comprises receiving a user selection from a displayed user interface accessible from a touchscreen attached to a computing device.

5. The method of claim 1 wherein receiving one or more semantic identifiers comprises receiving a user selection from audio input data mapped to one or more categories.

6. The method of claim 1 wherein receiving one or more filters comprises receiving at least one filter related to a user selected language for search results.

7. The method of claim 1 wherein receiving one or more filters comprises receiving at least one filter related to a user selected geographic region for search results.

8. The method of claim 1 wherein selecting a target search engine comprises receiving from the user a Uniform Resource Locator (URL) of a search engine external to a computer system performing the method.

9. The method of claim 1 wherein generating the Boolean query comprises adding additional terms to terms provided by a user and placing the terms in a query string appended to a search engine URL.

10. The method of claim 1 further comprising, after displaying the received query results, receiving user input related to the quality of results received and storing information about the user input to refine subsequent query results.

11. A computer system for improving search results from a search engine, the system comprising:

a processor and memory configured to execute software instructions embodied in the following software components;

a user interface component configured to interact with a search user to receive information describing content that the search user wants to find and to deliver results to the search user;

a semantic selection component configured to receive a selection of one or more categories that semantically refine the content that the search user wants to find, wherein the selected categories identify content without at least some inherent ambiguities of keywords;

a filtering component configured to receive zero or more filters from the search user that further refine the content that the search user wants to find;

a library component configured to store in a data store data that describes one or more categories, filters, and other information used by the system;

a search engine selection component configured to select a search engine external to the system to which to provide a query and from which to receive one or more search results;

a search string generation component configured to generate a search string for delivery to a search engine based on one or more received categories and filters;

a search engine interface component configured to communicate with one or more selected search engines to provide the generated search string and receive one or more search results from the search engine for presentation to the user; and

a results processing component configured to manage information gathered from search user interaction with the received search results.

12. The system of claim 11 wherein the user interface component is further configured to provide a non-keyboard input method such as a touchscreen or audio input interface.

13. The system of claim 11 wherein the semantic selection component is further configured to identify one or more topic areas from which the user wants to receive search results.

14. The system of claim 11 wherein the filtering component is further configured to receive additional information not related to the semantic meaning of what the user is looking for but that can help to eliminate or include some types of results in the search.

15. The system of claim 11 wherein the search engine selection component leverages one or more existing search engines by providing a front-end that refines search queries provided by the user by adding additional search terms that eliminate at least some unwanted results.

16. The system of claim 11 wherein the search string generation component is further configured to include text entered by the user combined with text identified by the system based on automatic analysis of what the user is searching for;

17. The system of claim 11 wherein the search string generation component is further configured to assemble a series of variables derived from the received categories and filters into a Boolean string for input to the selected search engine.

18. The system of claim 11 wherein the search string generation component is further configured to incorporate information from previously provided editorial evaluation of past search results.

19. The system of claim 11 wherein the results processing component is further configured to provide an editorial control through which the search user can indicate relative relevance of search results so that future search results can be sorted or filtered based on the results users have found relevant in the past.

20. A computer-readable storage medium comprising instructions for controlling a computer system to storing user preferences related to search results, wherein the instructions, upon execution, cause a processor to perform actions comprising:

receiving one or more target search engines from the user;

receiving a default language in which to provide search results;

receiving one or more additional languages in which to include search results, wherein the system treats results in the default language as higher ranked than those in additional languages;

receiving one or more included ontologies for the search;

receiving one or more geographic preferences to apply to search results; and

storing the received user preferences for use in subsequent searches.
