Abstract

In some examples, a system performs language processing of text of an information page to determine whether the text refers to an online resource, and in response to determining that the text refers to the online resource, identify the text as an implicit reference to the online resource. The system derives a link to the online resource based on the implicit reference, the derived link useable in accessing the online resource.

Claims

1. A non-transitory machine-readable storage medium comprising instructions that upon execution cause a system to:

perform language processing of text of an information page to determine whether the text refers to an online resource, and in response to determining that the text refers to the online resource, identify the text as an implicit reference to the online resource;

determine, based on analyzing information describing a structure of an information site, a search interface comprising an input field;

in response to identifying the text as the implicit reference to the online resource, perform a search based on inputting a search term into the input field of the search interface;

obtain a search result referring to the online resource in response to the search; and

use a link of the search result as a link to the online resource.

4. The non-transitory machine-readable storage medium of claim 1, wherein the instructions upon execution cause the system to invoke a classifier that classifies text in online pages;

apply the classifier to the text of the information page in an attempt to derive the link to the online resource based on the implicit reference;

determine whether the classifier was able to derive the link to the online resource,

wherein the determining of the search interface and the performing of the search are in response to determining that the classifier was not able to derive the link to the online resource.

5. The non-transitory machine-readable storage medium of claim 1, wherein the language processing comprises a natural language processing.

6. The non-transitory machine-readable storage medium of claim 1, wherein the link to the online resource comprises a structured or semi-structured hyperlink.

8. The non-transitory machine-readable storage medium of claim 1, wherein the information site is a website, and wherein the analyzing of the information describing the structure of the information site comprises analyzing a Document Object Model (DOM) of the website.

9. The non-transitory machine-readable storage medium of claim 1, wherein the search term input into the input field of the search interface comprises the text.

10. The non-transitory machine-readable storage medium of claim 1, wherein the instructions upon execution cause the system to:

derive the search term based on replacing a word or word phrase in the text with a synonym.

21. The non-transitory machine-readable storage medium of claim 1, wherein the search produces a plurality of search results, and wherein the instructions upon execution cause the system to:

rank the plurality of search results;

select a selected search result of the plurality of search results based on the ranking,

wherein the link to the online resource is from the selected search result.

22. The non-transitory machine-readable storage medium of claim 21, wherein the inputting of the search term into the input field of the search interface comprises inputting a plurality of search terms into one or more input fields of the search interface.

2-3. -3. (canceled)

7. (canceled)

11. A system comprising:

a processor; and

a non-transitory storage medium storing instructions executable on the processor to;

identify text in an information page that refers to an online resource as an implicit reference in response to determining that the text refers to the online resource;

invoke a classifier in response to identifying the implicit reference;

use, by the classifier, a model that defines patterns of text that indicate presence of entities that are part of links to online resources, in an attempt to derive a link to the online resource based on the implicit reference;

determine whether the classifier was able to derive the link to the online resource;

in response to determining that the classifier was not able to derive the link to the online resource;

determine, based on analyzing information describing a structure of an information site, a search interface comprising an input field,

perform a search based on inputting a search term into the input field of the search interface,

obtain a search result referring to the online resource in response to the search; and

use a link of the search result as the link to the online resource; and

access the online resource using the link to the online resource.

12. The system of claim 11, wherein the instructions are executable on the processor to:

use natural language processing to detect the text that refers to the online resource.

13. The system of claim 11, wherein the link to the online resource comprises a structured or semi-structured hyperlink.

15. The system of claim 11, wherein the information site is a website, and wherein the search interface is a search interface of the web site.

16. The system of claim 11, wherein the search term input into the input field of the search interface comprises the text.

17. The system of claim 11, wherein the instructions are executable on the processor to:

perform a plurality of searches using a plurality of search terms in the search interface, the plurality of search terms being variants of the text;

obtain a plurality of search results in response to the plurality of searches; and

use links of the plurality of search results to obtain the link to the online resource.

18. The system of claim 17, wherein the instructions are executable on the processor to:

rank the plurality of search results,

wherein the using of the links of the plurality of search results to obtain the link to the online resource is based on the ranking.

23. The system of claim 11, wherein the instructions are executable on the processor to:

in response to determining that the classifier was able to derive the link to the online resource, use the link to the online resource derived by the classifier in accessing the online resource.

14. (canceled)

19. A method performed by a system comprising a hardware processor, comprising:

performing natural language processing of text of a web page to determine whether the text refers to a web resource, and in response to determining that the text refers to the web resource, identifying the text as an implicit reference to the web resource; and

deriving a link to the web resource based on the implicit reference, the deriving comprising;

determining, based on analyzing information describing a structure of a website, a search interface comprising an input field;

in response to identifying the text as the implicit reference to the web resource, perform a search based on inputting a search term into the input field of the search interface of the website;

obtain a search result referring to the web resource in response to the search; and

use a hyperlink of the search result as the link to the web resource.

20. The method of claim 19, wherein the search term input into the input field of the search interface comprises the text.

24. The method of claim 20, wherein the performing of the search further comprises inputting a variant of the text into the search interface of the web site to identify a further search result, and wherein the deriving further comprises:

selecting a selected search result from the search result and the further search result.

25. The method of claim 19, wherein the deriving further comprises:

applying a classifier to the text of the web page in an attempt to derive the link to the web resource based on the implicit reference;

determining whether the classifier was able to derive the link to the web resource,

wherein the determining of the search interface and the performing of the search are in response to determining that the classifier was not able to derive the link to the web resource.
