The program code can also cause the processor to output the facets with the result set in response to the query.
Some systems provide filters for filtering search results. For example, a user may submit a search query, and in order to help the user narrow down the list of results, a system may suggest several filters for the user to choose. These filters are referred herein as facets. As used herein, facets refer to dimensions along which each result of a query may be classified. For example, a search engine on a website selling camera lenses may have a set of facets including camera type, lens focal length, lens speed, etc., for a query of a lens made by a particular manufacturer. These facets may be chosen by a system based on the results returned for the query. The system may then suggest one or more facets to a user to help narrow down the search results. In this way, the system may enable the classifications to be accessed and ordered in multiple ways rather than in a single, pre-determined, taxonomic order. However, such facets may be limited to a set of predefined facets. Such a search engine may not be able to automatically adapt to add facets for additional features as they emerge, such as auto-focus abilities, eye or face tracking capabilities, etc. Rather, such search engine may simply count the number of times a concept appears in a set of search results and display a set of predefined facets accordingly. Moreover, queries submitted to general search engines may have many different intents. For example, a submitted query of “jaguar” may be intended to refer to an animal or a car manufacturer. Predefining various sets of facets for all possible query intents may be very difficult if not impossible.
According to embodiments of the present disclosure, a processor of a system can receive concepts extracted from a result set corresponding to a query and result associations for each extracted concept. The processor can build a graph based on the extracted concepts, wherein the graph includes a number of nodes representing the extracted concepts and weighted edges representing similarity between the extracted concepts extracted from shared results. For example, two nodes may only share an edge if the concepts were detected together in at least one of the results. Weights may then be assigned to the edges based on similarity. The processor can partition the graph into subgraphs with vertices corresponding to candidate facets for vertices having higher sums of weighted edges. The processor can further rank the candidate facets. The processor can select higher ranked candidate facets to use as facets. The processor can then output facets with a result set in response to the query. Thus, embodiments of the present disclosure allow users to narrow down a result set of a query using the facets, which may reduce user effort in finding an intended result. The techniques enable the automated generation of facets from a set of predefined meaningful concepts.

In the example of
The concept extractor 104 can then generate groups of concepts with result associations. For example, each group of concepts may be associated with a particular result in the result set 112. In various examples, the concept extractor 104 may have access to a closed set of high-level categories for one or more domains. As one example, for the domain of computer science, the arXiv archive computer science categories may be used. For example, these categories include “artificial intelligence”, “computation and language”, “computational complexity”, “computational engineering”, “finance, and science, computational geometry”, “computer science and game theory”, “computer vision and pattern recognition”, “computers and society”, “cryptography and security”, “data structures and algorithms”, “databases”, “digital libraries”, discrete mathematics“, distributed, parallel, and cluster computing”, “emerging technologies”, “formal languages and automata theory”, “general literature”, “graphics”, “hardware architecture”, “human-computer interaction”, “information retrieval,” information theory”, “logic in computer science”, among other categories. The concept extractor 104 may also have access to a knowledge base. For example, the knowledge base may be Wikipedia. The high level categories for one or more domains can be mapped to categories of the knowledge base. In various examples, a mention detection may be run as part of the concept extractor 104 ingestion pipeline and mentions are stored in an index. For example, the mention detection tool may be any suitable general purpose mention detection tool, such as TagMe, first version released in 2010, a natural language understanding (NLU) tool, or a Term Wikifier (TW). The concept extractor 104 may apply the mention detection tool to all documents in the result set 112. In various examples, the concept extractor 104 can traverse the category tree of the knowledge base and keep only those concepts whose categories are under the hierarchy of the domain. For example, only those concepts whose categories lead to one of the above categories of the hierarchy of the domain may be included in the groups of concepts with result associations 114. The concept extractor 104 can send the groups of concepts with result associations 114 to the facets service 108. As one example, the paper “Sparsity-certifying Graph Decompositions” was parsed to extract concepts using a mention detection tool. The surface form of the extracted concepts as appearing in the paper were: “Pebble game”, “spanning trees”, “matroid”, “verticies”, and “terminology”. The extracted concepts associated with these phrases were: “Pebble game”, “Spanning tree”, “Matroid”, “Vertex (graph theory)”, and “terminology”. The corresponding high level categories associated with these concepts were: “computational complexity theory”, “computational complexity theory”, “discrete mathematics”, “discrete mathematics”, and “computational linguistics”.
In various examples, the concepts extracted by the concept extractor 104 using the mention detection tool may still include concepts that are not very informative. For example, the concepts may be too general for use as filters. To continue the example above, the concepts “verticies” and “terminology” may not be very helpful for use as facets. In some examples, the concept extractor 104 can refine the set of concepts using information from the knowledge base. For example, if a concept mentioned frequently in the knowledge base has few inlinks, it may likely be very generic. Therefore, the concept extractor 104 can remove concepts with a number of inlinks that does not exceed a first threshold or exceeds a higher second threshold. For example, a concept with high number of inlinks may be too general so it is not very informative) In various examples, the concept extractor 104 can further filter the extracted concepts. In some examples, concept extractor 104 can filter the extracted concepts by long paths from top level categories. For example, extracted concepts with a path longer than a threshold path p may be filtered from the concepts with result associations 114. In some examples, the concept extractor 104 can filter the extracted concepts by pre-retrieval query performance prediction (QPP) features. For example, the concept extractor 104 can use QPP to estimate if a query is difficult based on properties of query terms. As one example, a “clarity” property may be measured as the difference of probability of a term in a collection compared to the average probability of all terms. The concept extractor 104 can filter out concepts with low clarity value. In various examples, the concept extractor 104 can calculate similar properties for the concepts.
The facets service 108 can dynamically generate facets 116 based on the groups of concepts with result associations 114 using graph partitioning. Given a query and a result set containing concepts, the facets service 108 can rank the concepts according to some objective. For example, the facets service 108 can rank concepts by their ability to extract homogeneous intents from the result set. In some examples, the facets service 108 can select the top-k concepts to maximize the objective and use the top-k concepts as facets. The facets service 108 can rank concepts by maximizing the separation of the result set to a diversified set of user intents.
For example, the facets service 108 can build a graph from the extracted concepts. The facets service 108 can model the co-occurrence of concepts in the groups of concepts with result associations 114 as nodes connected by edges in an undirected graph. In some examples, the nodes may be weighted based on the number of inlinks of the concepts that the nodes represent, as described above.
As noted above, an edge may exist between two nodes representing concepts in the graph if the two concepts appear together in at least one of the results in the result set 112. In some examples, an edge weight may also be included to indicate the similarity between those concepts. For example, the weight of the edge may represent the similarity between the concepts. In various examples, the facets service 108 can weigh edges using a normalized pairwise mutual information (PMI) or a normalized Google distance (NGD). For example, the facets service 108 can calculate a normalized Google distance between two concepts x and y using corpus data via the equation:
where f(x) is the number of pages that concept x appears in the knowledge base, f(y) is number of pages that concept y appears in the knowledge base, f(x,y) is number of pages that both concepts x and y appear in the knowledge base, and N is the total number of pages in the knowledge base. In various examples, the facets service 108 can calculate a normalized PMI using corpus data via the equation:
where p(x) is the number of inlinks of x, p(y) is the number of inlinks of x, and p(x,y) is the number of pages that point to both x and y. For example, the number of inlinks of x may be the number of links to x, or number of pages that point to x in the knowledge base. In some examples, the facets service 108 can calculate similarity between concepts using a cosine similarity between pretrained embeddings of a knowledge base, such as Wikipedia. For example, pretrained embeddings for words may be created using Word2vec, first released in 2013. Pretrained embeddings for concepts in Wikipedia may be created using Wikipedia2vec, version 0.2.4 first released in May 2018.
In various examples, the facets service 108 can filter the groups of concepts by choosing a vertex corresponding to one of the concepts as a candidate facet to filter results. For example, results filtered by a candidate facet may only contain concepts that are neighbors of the facet in the graph. Choosing a particular concept as a candidate facet thus partitions the graph into a subgraph and a remaining portion of the graph. In some examples, the candidate facets may be chosen by selecting a vertex that yields the most highly related concepts in the resulting subgraph. The resulting subgraph may thus be homogenous, so as to represent a distinct user intent. For example, the sum of edge weights in the subgraph induced by partitioning the graph using a candidate facet may represent the homogeneity of the subgraph. In various examples, candidate facets may be chosen based on a sum of the weights exceeding some threshold homogeneity. The resulting candidate facets may be dynamic facets that represent different distinct intents of a user in submitting the query.
In various examples, the facets service 108 can then rank the candidate facets using a utility function. For example, the facets service 108 can rank the candidate facets using the equation:
U(ci)=wn(ci)Σc
where N(ci) is the neighbors of candidate facet ci and wn is the node weight. The node weight helps avoid facets that are too generic. In various examples, the facets service 108 can calculate the utility of each candidate facet in a predetermined number of top documents in a result set. For example, the facets service 108 can calculate the utility of each of the candidate facets in the 100 top documents of the result set. The facets service 108 can then rank the candidate facets according to the calculated utility. In some examples, the facets service 108 can approximate the ranking using a graph neural network to improve speed. In various examples, the facets service 108 can include a predetermined number of top candidate facets in the set of facets 116. For example, a top 10 number of facets may be returned to be used in the set of facets 116.

A user may then select one or more facets for filtering of the results. For example, the user interface 102 may receive a selection of one of the facets and filter the results displayed to the user accordingly. For example, in response to the user selecting a facet, the result set is filtered to show only results that contain the selected facet. A new concepts graph may then be built from the filtered results and new facets calculated and suggested back to the user. In this manner, the user may be able to more efficiently search a variety of topics.
It is to be understood that the block diagram of
At block 202, a processor receives a query, a result set corresponding to the query, and a knowledge base. For example, the result set may be received from a search engine in response to sending the search engine the query. In various examples, the knowledge base may be a knowledge graph. As one example, the knowledge base may be Wikipedia.
At block 204, the processor extracts concepts from the results sets using the knowledge base. In some examples, the processor can filter the extracted concepts by long paths from top level categories. In various examples, the processor can filter the extracted concepts by pre-retrieval QPP features.
At block 206, the processor builds a graph based on the extracted concepts, where the graph includes a number of nodes representing concepts and weighted edges representing similarity between concepts extracted from shared results. For example, an edge may only be generated between two nodes if the two concepts were detected in a same result. Weights may then be assigned to the edges based on similarity. In some examples, the processor can calculate a weight for each of the nodes based on a number of inlinks of the concept each node represents. In various examples, the processor can calculate a weight for each of the edges using a normalized pairwise mutual information (PMI) or a normalized Google distance (NGD).
At block 208, the processor partitions the graph into subgraphs with vertices corresponding to candidate facets for vertices having higher sums of the weighted edges.
At block 210, the processor ranks the candidate facets. In some examples, the processor can calculate a utility for each of the candidate facets and rank the candidate facets by the calculated utility. In various examples, the processor can approximate the ranking of the candidate facets using a graph neural network. For example, the graph neural network may be trained to rank candidate facets by the suggested utility instead of calculating the utility for each concept.
At block 212, the processor selects higher ranked candidate facets to use as facets. At block 214, the processor outputs the facets with the result set in response to the query.

In some scenarios, the techniques described herein may be implemented in a cloud computing environment. As discussed in more detail below in reference to at least
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.
