PRESENTING SUGGESTED FACETS
Method and system to present suggested facets is described. The system includes a search request detector, a search results generator, a facet selector, and a presentation module. The search request detector detects a search request comprising search criteria. The search results generator 220 retrieves search results based on the search criteria. The facet selector selects a suggested facet from a plurality of facets, where a facet represents a category may have a variable value and indicates a filter for refining search results. The presentation module generates a list of items that includes search results and the suggested facet.
1 . A computer-implemented method comprising:
detecting, using at least one processor, in the on-line social network system, a search request from a client computer, the search request comprising search criteria;
retrieving search results based on the search criteria;
selecting, using at least one processor, a suggested facet from a plurality of facets, the plurality of facets maintained in in an on-line social network system, a facet from the plurality of facets representing a category and having a variable value, the facet indicating a filter for refining search results in the on-line social network; and
generating a list of items for presentation at the client computer, the list of items comprising the search results and the suggested facet.
2 . The method of claim 1 , comprising calculating respective facet scores for facets from the plurality of facets, wherein the selecting comprises utilizing the facet scores.
3 . The method of claim 2 , wherein the calculating of the respective scores comprises utilizing historical data with respect to the facets.
4 . The method of claim 3 , wherein the historical data comprises respective frequencies of use for the facets over a period of time.
5 . The method of claim 3 , wherein the historical data indicates respective frequencies of subsequent clicks occurrences for the facets.
6 . The method of claim 2 , wherein the calculating of the respective value scores comprises determining entropy for a value from values associated with a facet from the facets, the entropy indicating frequency of occurrence of the value in the retrieved search results.
7 . The method of claim 2 , wherein the calculating of the respective scores comprises utilizing a number of the retrieved search results.
8 . The method of claim 7 , wherein the selecting of the suggested facet is in response to determining that the number of the retrieved search results is equal or greater than a predetermined threshold value.
9 . The method of claim 1 , comprising calculating respective value scores for values associated with the facets, wherein the selecting comprises utilizing the value scores.
10 . The method of claim 1 , wherein the generating of the list of items for presentation at the client computer comprises determining a position of the suggested facets in the list of items.
11 . A computer-implemented system comprising:
a search request detector, implemented using at least one processor, to detect, in the on-line social network system, a search request from a client compute the search request comprising search criteria;
a search results generator, implemented using at least one processor, to retrieve search results based on the search criteria;
a facet selector, implemented using at least one processor, to select a suggested facet from a plurality of facets, the plurality of facets maintained in in an on-line social network system, a facet from the plurality of facets representing a category and having a variable value, the facet indicating a filter for refining search results in the on-line social network; and
a presentation module, implemented using at least one processor, to generate a list of items for presentation at the client computer, the list of items comprising the search results and the suggested facet.
12 . The system of claim 11 , wherein the facet selector is to calculate respective facet scores for facets from the plurality of facets and to utilize the respective facet scores to select the suggested facet.
13 . The system of claim 12 , wherein the facet selector is to calculate the respective facet scores utilizing historical data with respect to the facets.
14 . The system of claim 13 , wherein the historical data comprises respective frequencies of use for the facets over a period of time.
15 . The system of claim 13 , wherein the historical data indicates respective frequencies of subsequent clicks occurrences for the facets.
16 . The system of claim 12 , wherein the facet selector is to determine entropy for a value from values associated with a facet from the facets to calculate the respective facet scores, the entropy indicating frequency of occurrence of the value in the retrieved search results.
17 . The system of claim 12 , wherein the facet selector is to calculate the respective facet scores utilizing a number of the retrieved search results.
18 . The system of claim 17 , wherein the facet selector is to select the suggested facet in response to determining that the number of the retrieved search results is equal or greater than a predetermined threshold value.
19 . The system of claim 11 , wherein the facet selector is to calculate respective value scores for values associated with the facets, and to utilize the respective value scores to select the suggested facet.
20 . A machine-readable non-transitory storage medium having instruction data to cause a machine to perform operations comprising:
detecting, in the on-line social network system, a search request from a client computer, the search request comprising search criteria;
retrieving search results based on the search criteria;
selecting a suggested facet from a plurality of facets, the plurality of facets maintained in in an on-line social network system, a facet from the plurality of facets representing a category and having a variable value, the facet indicating a filter for refining search results in the on-line social network; and
generating a list of items for presentation at the client computer, the list of items comprising the search results and the suggested facet.
