Search engines are used to locate a variety of types of information. While returning lists of links to relevant documents is now a familiar format, it is not necessarily a convenient format. In order to find a particular piece of information, the user typically must click through a link to review the corresponding document. The user may have to repeat this process multiple times if the desired information is not located in the first document accessed by the user.
In various embodiments, a system and method are provided for detecting entity information contained within search results. The detected entity information can be used to determine a category of entity as well as a specific entity within the search results. Entity information can be extracted from the documents associated with the search results. This information can be used as part of the information for an entity card, which can be displayed to a user in conjunction with and/or in place of the search results.

In various embodiments, when a search query is received, a plurality of search results can be generated by a search engine. The results generated by the search engine can then be analyzed to identify whether an entity category is indicated by the results. This identification can be based in part on identification of one or more category-oriented sites in the results. The results can be further analyzed to determine an intended entity. Based on the intended entity, an entity card corresponding to the entity can be prepared and displayed with the search results. Optionally, one or more of the generated search results can be excluded from display or incorporated into the entity card based on the intended entity.
- Category Templates
In the discussion below, an entity card refers to an enhanced entity-specific presentation of information. An entity card can include a variety of types of information about an entity. An entity card can allow such information to be presented to a user in response to a search query, so that a user does not have to sift through document links to obtain the information.
Determining a user's intent associated with a search query can pose a variety of problems. One method for identifying a user's intent can be to determine if the search query is related to an entity. An entity can refer to a type of person such as an author, politician, or sports player; a type of product such as a movie, book, or a consumer good; or a type of place such as a restaurant, hotel, recreation area, or retail store. However, identifying an entity related to a search query also creates difficulties. Many conventional methods attempt to build lists of entities that can be matched to terms in a search query. Keeping such lists up to date can be difficult and time consuming. Additionally, the entity related to a search query may not be included in the search terms.
In various embodiments, entity information can be determined dynamically based on the search results responsive to a search query. Entities can be identified based in part on identifying search results from documents that are known to correspond to a particular category. Numerous web sites exist that attempt to track the current status of a variety of entities. For example, multiple web locations are available that track movies, hotels, consumer electronics, or books. These sites can be referred to as category-oriented sites. Category-oriented sites typically track current developments within the specific category of interest, and therefore can provide current information about entities within the category. The number and/or identity of category-oriented sites typically changes slowly over time, so identifying appropriate sites as being related to a category can be a manageable task. A document associated with a uniform resource locator (URL) from one of these sites can have an increased likelihood of association with a category.
For documents from category-oriented sites, one or more category templates can be constructed. The structure of a document at a category-oriented site is usually consistent between entities described on the site. This consistency of presentation can be used to construct a template for extracting information from the site. For example, a category-oriented site that provides information about movies will typically have a consistent presentation format. The director of a movie will be noted in a certain way, such as at a certain place in a document or with the heading “Director” adjacent to and/or above the director's name. This expected presentation format can be used to construct a template for extracting the information from the document. Note that a site could be considered as a category-oriented site for more than one category. For example, an online retailer may carry products that include consumer electronics, DVDs, and computer games. The online retailer can have one or more URL components that correspond to each of these areas. Thus, depending on the search query, the appearance of a document from the online retailer could correspond to a movie category, a game category, or a consumer goods category.
A template can be constructed for each category-oriented site. A template can include at least two components. One part of a template can be a URL component. The URL component represents an initial portion of a URL. A document that matches the initial portion of a URL template can be a document from a known category-oriented site. The second component of a template can be an extraction format component. The extraction format component provides a specification for a plurality of data fields, including the type of information the can be extracted for each data field, as well as a specification of how to extract the information. Any convenient type of specification can be used. For example, the specification can identify a specific location in a document to retrieve a piece of information, such as taking a value from the second field in the fifth line of a document. Alternatively, a specification can be tag driven, such as specifying to first identify a header such as “title” or “movie title”, and then taking the information or word that appears in a certain relation to the header.
In addition to the category templates based on the category-oriented sites, one or more category templates that have an open format can be constructed for a category. The open format category templates can be constructed to extract the same information as the templates for the category-oriented sites. The open format templates can be similar to the tag driven templates for a category-oriented site, as the open format templates will be applied to pages that do not match a URL component.
Note that each open format template can be applied to each responsive result, or to each responsive result that is identified as corresponding to an identified entity. This can lead to extraction of multiple values for each data field from the same document. To make this data more useful for each document, a consistency check can be performed to determine which open format template was successful in extracting data for a given data field. For example, for a given document, the multiple values for each field can be compared to the values extracted from a document from a category-oriented site. Since the likelihood of an accidental match is low, a matching value is likely to be the correctly extracted value. Another type of check can be a consistency check versus the values extracted using open format templates from other documents. Again, the likelihood of an accidental match is low, so a match likely indicates a successful extraction for the field.
- Category and Entity Identification
Category-oriented sites can be determined by any convenient method. The category-oriented sites can be identified manually. Alternatively, the category-oriented sites can be determined by submitting known searches that should return category specific results. The sites that appear most frequently can be considered as category-oriented sites.
When a search query is received, a conventional search engine can be used to generate a plurality of responsive results or documents. In the embodiments below, a portion of the responsive documents can be analyzed to determine category or entity information. This can correspond to the top 10 responsive results, or the top 20, or the top 50, or any other convenient number. The responsive documents can be analyzed to determine an entity category. One part of the analysis can be to match documents to the URL component of the category templates. In an embodiment, at least one URL component match can be required in order to make an identification of an entity category. Another part of the analysis can be to match metadata from a search result with known terms. For example, metadata terms such as “movie”, “trailer”, or “film” could be associated with a movie site. The metadata can correspond to metatags for the document, or the caption of the document that is displayed as part of the search results, or any other information associated with the document that is available when the document is returned as a search result.
Matches to either the category template or the metadata can then be weighted to determine a score for whether a search query corresponds to a category. For example, each document that matches a URL component can contribute to a score for that category. Additional weight or score can be assigned for the first document that matches a URL component. Additional weight or score can be assigned for a higher ranked search result that matches a URL component versus a lower ranked search result. Similar types of weightings can be used for metadata analysis.
Based on the scores, an intended category for the search can be determined. For example, if three or more URL component matches are detected for a single category, the query can be assigned to that category. If multiple categories are detected based on matching the URL components, the highest ranked category can be assigned. In some embodiments, if no URL component matches are detected, there may be no selection of a category. Alternatively, no selection of a category can occur if there are one or fewer URL component matches.
The results can also be analyzed to determine if an entity is associated with the search query. In an embodiment, the category can be identified first and then the results can be analyzed to determine an entity. In such an embodiment, only entities that belong to the identified category are considered. In another embodiment, if an entity category is not detected, no entity is associated with the search query.
One part of entity analysis can be to apply a category template to a document from a category-oriented site. Because the document is from a category-oriented site, the extraction format of the document is likely to be known. Thus, the portion of the document that is likely to correspond to an entity is also likely to be known, and the entity can be directly extracted. Another part of entity analysis can be to apply one or more of the open format category templates to documents in the responsive results that are not from category-oriented sites. For example, many restaurant review sites list the name of the restaurant together with the address. An open format template could attempt to extract a restaurant name from an unknown document format by finding a group of text that corresponds to an address. The name immediately before the address could then be extracted as a possible entity. In embodiments where the category is not determined prior to analyzing an open format document to detect an entity, the open format templates used can correspond to the categories of any category-oriented sites in the search results.
The entity data extracted from the documents can then be analyzed to determine whether an entity associated with the search query can be identified. The analysis can compare the extracted information to determine if there is only one possible entity, or if one entity can be selected from several, or whether there is ambiguity that prevents determination of an entity.
Some entity determinations can be relatively straightforward. For example, the category selection may have been based on the presence of multiple category-oriented sites, with each of the category-oriented site documents indicating the same entity. In this situation, the entity from the category-oriented site documents can be selected as the entity.
In another example, one or more documents may be from category-oriented sites, but the extraction of entity information results multiple potential entities. This can be resolved in a variety of manners. One option can be to select the entity appearing in the largest number of category-oriented documents. Another option can be to select the entity extracted from the largest number of documents, regardless of the source. This option would include entities identified based on open format templates. Still another option can be to select an entity based in part on the ranking of the documents that each entity was extracted from. Still other options can be used based on giving various weights to the data extracted from documents, including combinations of any of the above options.
Yet another example can involve a situation where two or more categories are indicated by the search results. In some embodiments, the category can be determined first, and then only entities within the selected category are considered. In another option, each document can be analyzed according to each potential category. The methods for distinguishing between multiple entities as described above can then be used to select an entity. This would result in the corresponding selection of a category. Note that in this type of embodiment, the category weights could be included as another factor in deciding which entity is the best match for the search query.
Still another option can involve a situation where more than one piece of information is needed to differentiate between entities. For example, many restaurants are local businesses with only one location. As a result, more than one city may have a restaurant with the same name, even though the restaurants are different entities. The multiple restaurant entities with the same name can be referred to as entities that have the same primary identification.
The above situation can result in multiple restaurant review sites that have reviews based on a restaurant with the same primary identification, but each review is directed to a different restaurant entity. In this situation, the presence of several URL component matches and other metadata could clearly indicate a restaurant category, but a further determination may be needed to select an entity that corresponds to the search query. One option can be to look at additional extracted data fields for the category. In a restaurant example, typical additional information for extraction could include address and telephone number information. These fields can be compared to identify distinct restaurant entities that share the same name. This can be referred to as comparing secondary information for the various entities. After distinguishing between the entities based on the secondary information, the results corresponding to each distinct entity can be sorted into groups corresponding to each distinct entity. The methods noted above can be applied to determine an entity associated with the search query, such as selecting the entity that occurs most often, selecting the entity with the highest rated document, or other methods.
In some embodiments, the entity analysis can result in no entity being associated with a query. For example, if no category is assigned due to a lack of URL component matches, the entity analysis process can be stopped at that point. As another option, a scoring system can be used to determine the entity, and no entity may have a sufficiently high score and/or a sufficiently different score from other potential entities for an assignment to be made. In the restaurant example above, each restaurant may appear in only one document. The scoring system could require an appearance in more than one document to achieve a sufficient score for assignment as an entity. Alternatively, two restaurants may appear in a comparable number of documents, leading to both restaurants having similar scores. Because the scores are not sufficiently different, no entity may be assigned to the search query.
- Entity Card Extraction
In still other embodiments, multiple entities can be selected. In such embodiments, more than one entity can satisfy a criteria for being selected as an entity. For example, all identified entities can be selected, or entities with a score greater than a threshold value can be selected. In such embodiments, entity information can be extracted for each selected entity. The plurality of selected entities can be from a single category, or multiple entity categories can be identified as well. For example, an entity corresponding to a book and an entity corresponding to a movie can be selected. Optionally, an entity card can be displayed for each selected entity.
After identifying an entity, information regarding the entity can be extracted from the documents returned as search results. The extracted information can be used to generate an entity card. The entity card allows information regarding the intended entity to be displayed as part of the results page, without further clicks or other actions by a user to find the information.
In embodiments where at least one of the search results corresponds to a category-oriented site, the appropriate category template can be used to extract information for an entity card. The types of extracted information can vary based on the category. Examples of information that can be extracted include location information, contact information, and other information commonly requested for a given entity type. For example, an entity card for a movie could include the length of the film, the name of the director, and whether the film is a comedy, drama, or another type of movie. A restaurant entity card could include the type of food and a general indication of the price range. An entity card about a sports team could include the next scheduled game and the result of the prior game.
Another type of information that can be included in the entity card is one or more links to other types of relevant content. In some embodiments, the additional information presented in an entity card can correspond to information related to a secondary intent of the search query. For example, a search query related to a movie currently playing in theaters is likely to provide results such as movie reviews and theater locations. A movie no longer in theaters will instead likely have results related to stores where a copy of the movie can be purchased. This difference in the types of search results can represent a difference in the secondary intent of the search query. This secondary intent information can be used to include links relevant to the secondary intent as part of an entity card. The links included in the entity card may or may not correspond to a links that are part of the results from the search engine. The nature of the additional links can vary depending on the entity. For a restaurant, a link could be provided to an online site that handles reservations. For a sports or entertainment entity, such as a movie or a band, a link can be provided to a site that has tickets available. Links could also be provided to one or more third party review sites that are known to handle reviews for the category.
One of the advantages of forming an entity card based on the search results is that the information can be dynamically generated. Thus, any changes in the information reflected in the search results are automatically updated in the entity card as well. However, dynamically constructed entity cards can be used in conjunction with static entity cards containing previously obtained information. Use of previously obtained information can be helpful in situations where desired information cannot be extracted from the search results.
- Placement of Information Based on Entity Detection
In still another embodiment, an entity can be identified and an entity card including stored information can be provided. In such an embodiment, the methods of entity identification described above can be used to identify and select an entity. Stored information corresponding to the selected entity can then be used to form the entity card.
The intent of a search query in relation to an entity can be used to modify the placement and/or display of results and associated information. After determining an intended entity for a search query, the results can be reviewed to identify any results that are related to the entity. These can include results that correspond to a category-oriented site, results that include the name of the identified entity, or results where additional information regarding the identified entity was successfully extracted.
Identification of an entity can modify placement of information in a variety of ways. In an embodiment, identification of an entity can lead to selection of advertising related to the entity. The selected advertising can be placed on the page in a location near a search result corresponding to the entity. For example, if the highest ranked search results corresponding to the identified entity are results seven through nine, the advertisement can be placed near the bottom of a page showing the first ten search results. Similarly, if an entity card is generated, the entity card can be placed on the page in the vicinity of the highest ranked search result related to the entity, or near the second highest ranked result related to the entity.
- Examples of Entity Detection
Another impact of entity detection can be to remove some items from the display of search results. For example, one or more documents from the search results may be incorporated into an entity card. These results can optionally be removed from the displayed list of search results, as access to these documents is available instead via the entity card. Another way to modify the result display can be to display a portion of the responsive results, such as only the responsive results that are related to either the entity or the category of the entity. In such an embodiment, once an assignment is made of a category and entity, results that do not match the category and/or the entity can be omitted from the results display. Instead, an object can be displayed that allows the user to access the excluded results after an additional user action. For example, a link can be provided to indicate more results are available not related to the identified entity. This link can be accessed by a click through by the user or by moving a pointer or cursor over the location of the link. Alternatively, a drop down menu could be provided with the additional results.
In this hypothetical example, a user initially types the search term “godfather” into a search engine. The results generated by this search include a plurality of results from at least one category-oriented site related to movies. Additional category-oriented sites related to retail sales and/or video games are also in the search results. Since a category-oriented site is the highest ranked search result, the category selection is made based on the highest ranking category-oriented site. As a result, the category “movies” is selected.
After selecting the category, the category-oriented sites are used to detect the entity. This results in detection of multiple entities, as both the movie “Godfather” and the movie “Godfather II” are included in the search results. The movie “Godfather” is selected as the appropriate entity, based on the fact that “Godfather” was detected in more of the responsive results than “Godfather II”. The responsive results are then presented to the user, along with an entity card corresponding to the movie. The entity card is formed based on extracting information from the documents listed in the responsive results.
After viewing the presented results, the user modifies the search terms to “godfather restaurant”. A new set of search results is generated. In the new results, the top rated corresponds to a general review site that can be category-oriented, but for many categories. Many additional potential category-oriented sites are included within the top 20 results, corresponding to other known review sites. Based on metatags from the review site documents, a category of “restaurants” is selected.
Based on this category selection, the appropriate category templates can be selected to analyze both the category-oriented review sites. Open format category templates can also be used to analyze the other document. The search results include several distinct restaurants located around the U.S., as well as a chain of pizza restaurants. However, the only repeat appearance of location data is for a location in San Diego, Calif. The documents listing the San Diego, Calif. address are grouped together, and this entity is selected as the entity corresponding to the search query. Note that if each instance of the restaurant had appeared only once, in some embodiments no entity would have been identified as the intent would not be clear. Additional information can then be extracted regarding the entity from the responsive results that correspond to the entity.
