Abstract

A method includes determining whether an electronic source link of a curated item is broken. In response to the electronic source link not being broken, the method includes determining whether linked content at the electronic source link is consistent with a version of a document originally accessed on which the curated item is based (item document). In response to the linked content not being consistent with the item document, the method includes locating an alternative item or an alternative source for an inconsistent source link. In response to the electronic source link being broken, the method includes locating an alternative item or an alternative source for a broken source link. Following an expiration date of the curated item, the method also includes locating updated content that is relevant to the curated item.

Claims

1. A method, comprising:

determining whether an electronic source link of a curated item is broken;

in response to the source link not being broken;

determining whether linked content at the electronic source link is consistent with a version of a document originally accessed on which the curated item is based (item document), and

in response to the linked content not being consistent with the item document, locating an alternative item or an alternative source for an inconsistent source link;

in response to the electronic source link being broken, locating an alternative item or an alternative source for a broken source link; and

following an expiration date of the curated item, locating updated content that is relevant to the curated item.

2. The method of claim 1, further comprising generating a notification message indicating whether the electronic source link of the curated item is broken, whether the linked content is consistent with the item document, and the updated content.

3. The method of claim 1, further comprising:

waiting a particular interval;

after the particular interval, determining whether the electronic source link is broken;

in response to the source link not being broken, determining whether linked content at the electronic source link is consistent with a version of the item document, and in response to the linked content not being consistent with the item document, locating an alternative item or an alternative source;

in response to the electronic source link being broken, locating an alternative item or an alternative source; and

locating updated content that is relevant to the curated item in response to passing of an expiration date of the curated item.

4. The method of claim 1, wherein the determining whether the electronic source link of the curated item is broken includes sending a request to the electronic source link, the method further comprising:

in response to a request failure, updating a status of the item in the item table as broken; and

in response to a request success, updating a status of the item in the item table as live.

5. The method of claim 1, wherein the locating the alternative item or the alternative source for a broken source link includes:

attempting to locate internal alternatives based on a comparison between the item document and the one or more cached documents in the search index (stored documents); and

attempting to locate external alternatives by executing a search on an external search engine.

6. The method of claim 5, wherein the locating the alternative item or the alternative source for a broken source link includes:

assigning one or more element weights to one or more elements of the item document;

in response to the internal alternatives being located, sorting the internal alternatives; and

selecting a specific number of the internal alternatives,

wherein;

the comparison includes context similarities between the item document and the one or more cached documents in the search index (stored documents) that factor in the element weights; and

search terms entered into the external search engine include a keyword within the item document.

7. The method of claim 6, wherein the locating the alternative item or the alternative source for a broken source link includes in response to no internal alternatives and no external alternatives being located, making a broken link associated with the curated item unselectable.

8. The method of claim 1, wherein the locating the updated content includes:

in response to the expiration date being past, combining content of one or more curated items;

attempting to identify one or more of the cached documents in the search index (stored documents) which are newer than the curated item as relevant content based on a comparison between the combined content and the cached documents;

sorting the identified stored documents based on a context similarity between the combined content and the identified stored documents; and

selecting a particular number of identified cached documents based on the context similarity.

9. The method of claim 1, wherein the locating the alternative item or the alternative source for the inconsistent source link includes:

determining whether there is a match between the item document and the linked content; and

in response to there not being a match between the item document and the linked content;

assigning one or more element weights to one or more elements of the item document;

attempting to locate internal alternatives based on a comparison between the item document and one or more cached documents in the search index (stored documents), wherein the comparison includes context similarities between the item document and the stored documents that factor in the element weights;

in response to the internal alternatives being located, sorting the internal alternatives; and

selecting a specific number of the internal alternatives.

10. The method of claim 9, wherein the locating the alternative item or the alternative source for the inconsistent source link includes:

combining content of one or more curated items;

extracting keywords from the combined content;

attempting to locate external alternatives by executing a search on an external search engine using the extracted keywords;

ranking external search results according to a comparison with the common content; and

narrowing the ranked search results by an update time.

11. A non-transitory computer-readable medium having encoded therein programming code executable by a processor to perform or control performance of operations comprising:

determining whether an electronic source link of a curated item is broken;

in response to the electronic source link not being broken;

determining whether linked content at the electronic source link is consistent with a version of a document originally accessed on which the curated item is based (item document), and

in response to the linked content not being consistent with the item document, locating an alternative item or an alternative source for an inconsistent source link;

in response to the source link being broken, locating an alternative item or an alternative source for a broken source link; and

following an expiration date of the curated item, locating updated content that is relevant to the curated item.

12. The non-transitory computer-readable medium of claim 11, wherein the operations further comprise generating a notification message indicating whether the electronic source link of the curated item is broken, whether the linked content is consistent with the item document, and the updated content.

13. The non-transitory computer-readable medium of claim 11, wherein the operations further comprise:

waiting a particular interval;

after the particular interval, determining whether the electronic source link is broken;

in response to the source link not being broken, determining whether linked content at the source link is consistent with a version of the item document, and in response to the linked content not being consistent with the item document, locating an alternative item or an alternative source;

in response to the electronic source link being broken, locating an alternative item or an alternative source; and

locating updated content that is relevant to the curated item in response to passing of an expiration date of the curated item.

14. The non-transitory computer-readable medium of claim 11, wherein the determining whether the electronic source link of the curated item is broken includes sending a request to the source link, the method further comprising:

in response to a request failure, updating a status of the item in the item table as broken; and

in response to a request success, updating a status of the item in the item table as live.

15. The non-transitory computer-readable medium of claim 11, wherein the locating the alternative item or the alternative source for a broken source link includes:
